Detailed ways

The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, the drawings only show some but not all structures related to the present invention.

Example 1

1a is a flowchart of a method for synchronizing cursor shape according to Embodiment 1 of the present invention. This embodiment is applicable to when a remote browsing service is implemented based on a pixel transfer method, and the client cursor pointer changes shape in real time with the cursor on the remote browsing server The method can be executed by a cursor shape synchronization device, the device can be implemented by means of software and/or hardware, and the device can be integrated in an electronic device, such as a client device such as a mobile phone or a computer.

Specifically, the cursor shape synchronization method provided in the first embodiment of the present invention can be applied to a remote browsing system, and is executed by a client in the remote browsing system. Wherein, the remote browsing system may implement a remote browsing service based on a pixel transmission method. The remote browsing system may include a client and a remote browsing server. The client can access the web browser content of the remote browsing server through the remote browsing mode. However, the content generated by the interface of the web browser without remote access in the client, such as the hypertext transfer protocol and the style required for the formation of the web page, can ensure that the client will not be attacked and user losses will be avoided. The client can be understood as a remote display interface for remotely browsing the content of the server page. The content of the remote page displayed on the client can be understood as a picture. When the cursor moves on the content of the remote page, the shape of the cursor will not change. For example, the cursor on the client is fixedly displayed as an arrow pointer. Access to the remote browsing server can be a terminal such as the cloud or a remote server. Remote browsing can reduce the attack risk borne by the client, reduce attack targets, and protect resources.

As shown in Figure 1a, the method specifically includes:

Step 110: After establishing a communication connection with the remote browsing server, acquire cursor attribute information of the local browser, and perform information binding.

The client and the remote browsing server both have their own local browsers. The client's local browser can implement the client's basic access to browsing. The local browser of the remote browsing server can realize the remote access of the client to browsing. The client's cursor shape can be changed through the native browser's styling interface. In the embodiment of the present invention, the client can bind the cursor attribute information of the local browser, so as to realize the synchronization of the cursor shape during remote browsing through the style interface of the local browser. The cursor can be understood as the indicator of the client, for example, the cursor can be the indicator displayed by the mouse on the display interface.

Specifically, to obtain the cursor attribute information of the local browser and bind the information, it may be to bind the Cursor attribute in the Cascading Style Sheets (CSS) of the local browser on the client canvas. The Cursor property can determine the cursor shape that is displayed when it is within the bounds of an element, such as question marks, small hands, crosses, arrows, move marks, text marks, and busy marks.

Step 120: Acquire the cursor shape notification information published by the remote browsing server, and process the cursor shape notification information to obtain the cursor shape information.

The cursor shape notification information may include cursor shape information. For example, the cursor shape notification information may be a concrete embodiment of the processed cursor shape information. Alternatively, the cursor shape notification information may include cursor shape information and other auxiliary information. The processing of the cursor shape notification information may be processing such as parsing or decoding the cursor shape notification information, so as to extract key information such as cursor shape information. The cursor shape information may be a specific embodiment of the cursor shape determined by the remote browsing server.

In an optional implementation manner of the embodiment of the present invention, before acquiring the notification information of the cursor shape published by the remote browsing server, the method further includes: determining the target position of the current cursor and the target content matching the target position, and comparing the target position and the target position with the target content. The target content is fed back to the remote browsing server.

The target position may be the position of the page where the cursor is located when the client performs remote browsing. The target content can be content in the page that matches the target location. For example, the target position of the cursor is the fourth word in the third line of the page position. The target content that matches the target location is the hyperlink content. The remote browser server can perform position synchronization with the target position of the client cursor, and determine the content type to which the target content matching the target position belongs, so as to determine the cursor shape according to the content type. For example, the shape of the cursor corresponding to the hyperlink content is a small hand; the shape of the cursor corresponding to the content seeking help is a question mark; the shape of the cursor corresponding to the text content is a text mark, which can indicate that the client user can select or copy the current content. Therefore, when the client performs cursor synchronization according to the cursor shape of the remote browser server, the client user can perform remote browsing access without perception.

Step 130: Update the bound cursor attribute information according to the cursor shape information to synchronize the cursor shape.

The cursor attribute information can be specifically set according to the cursor shape information, and the client can present the cursor shape according to the updated cursor attribute information, so that the client cursor shape is consistent with the remote browsing server, that is, the cursor shape synchronization is realized.

In an optional implementation of the embodiment of the present invention, after the cursor shape notification information is processed to obtain the cursor shape information, the method further includes: determining the cursor type according to the cursor shape notification information; when the cursor type is a custom type, Perform base64 decoding on the custom cursor text content in the cursor shape notification information, and generate cursor type information in image format. Updating the bound cursor attribute information according to the cursor shape information to synchronize the cursor shape includes: updating the bound cursor attribute information according to the cursor shape information and the cursor type information to synchronize the cursor shape.

The cursor shape that may be used by the remotely browsed page is the custom cursor shape of the website. In order to better enable the client user to perform remote browsing without perception, in this embodiment of the present invention, it can be determined whether the cursor type is a custom type. If the cursor type is a custom type, you can update the cursor shape under the custom type, so that the cursor shape of the client is exactly the same as that of the remote browsing server.

Specifically, the cursor shape notification information published by the remote browsing server may include custom cursor text content. If the cursor type is a non-custom type, that is, the default cursor type, the text content of the custom cursor can be empty data, or other forms of data representing the default cursor type. If the cursor type is a custom type, the custom cursor text content can be the information related to the custom cursor image information under the custom type. The customized cursor image information may be specific image information of one or more customized cursor shapes under the customized type. For example, the custom cursor image information may include image information of a little green hand; or, image information of a rose-shaped text logo, and the like.

In the embodiment of the present invention, in order to avoid data loss or garbled data when the custom cursor image information is transmitted between the remote browsing server and the client, the custom cursor image information can be encoded. For example, the custom cursor image information can be converted into text information for transmission, so as to realize the transmission of visible characters, thereby avoiding the problem of garbled characters. Therefore, in this embodiment of the present invention, the custom cursor text content may be content generated by the remote browsing server by performing base64 encoding conversion on the custom cursor image information. Specifically, through base64 encoding, the custom cursor image information originally encoded in binary can be converted into text content, which can facilitate transmission and avoid garbled characters.

In this embodiment of the present invention, when the cursor type is a custom type, the client can perform base64 decoding processing on the custom cursor text content in the cursor shape notification information, and generate cursor type information in an image format. The cursor type information can be in JSON format. JSON format is a data standard format in network communication, which can facilitate the client to synchronize cursor shape.

In an optional implementation of the embodiment of the present invention, updating the bound cursor attribute information according to the cursor shape information and the cursor type information, and performing cursor shape synchronization, includes: updating the cursor in the bound cursor attribute information according to the cursor type information Type, synchronize the cursor type; under the cursor type, update the cursor shape in the bound cursor attribute information according to the cursor shape information, and perform the cursor shape synchronization under the cursor type.

The client can determine the cursor name corresponding to the custom cursor image information corresponding to the custom cursor type according to the cursor type information, so that the cursor type in the cursor attribute information can be updated according to the cursor name, so as to realize the synchronization of the cursor types. Further, under the cursor type, specific cursor shape synchronization can be performed.

Exemplarily, the cursor shape corresponding to the default hyperlink content is a small white hand, and the cursor shape corresponding to the hyperlink content under the custom type is a small green hand. In the embodiment of the present invention, the cursor attribute information may be updated to a custom type corresponding to green through cursor type synchronization first; and then the cursor shape synchronization may be performed to update the cursor attribute information to green in the custom type corresponding to green tiny hand. Thus, the cursor shape synchronization under the cursor type can be realized, the cursor shape synchronization of the remote browsing page under the user-defined type can be realized, and the remote browsing access that the client user is completely unaware of can be realized.

In the technical solution of this embodiment, after establishing a communication connection with the remote browsing server, the cursor attribute information of the local browser is obtained, and information is bound; the notification information of the cursor shape published by the remote browsing server is obtained, and the cursor shape The notification information is processed to obtain the cursor shape information; the bound cursor attribute information is updated according to the cursor shape information, and the cursor shape is synchronized, which solves the problem that the client cursor pointer cannot be changed in real time when the remote browsing service based on pixel transmission is currently implemented. It realizes the synchronization of the cursor shape of the remote browsing server in the remote browsing system to the client, and the client cursor can change the shape in real time with the remote browsing server, so as to achieve the effect that the client does not perceive the remote browsing access.

Specifically, FIG. 1b is a flowchart of another method for synchronizing a cursor shape provided by Embodiment 1 of the present invention. As shown in FIG. 1b, the specific application process of the cursor shape synchronization method provided by the embodiment of the present invention may be as follows: the client initiates a remote browsing access request to the remote browsing server, and the client establishes a remote browsing session with the remote browsing server; Bind the cursor attribute of the mouse on the client canvas; the client obtains the cursor shape notification information published by the remote browsing server in real time; when the cursor shape notification information is obtained, it determines whether the cursor type is a custom type according to the cursor shape notification information; If no, update the cursor attribute information of the bound mouse according to the cursor shape information in the cursor shape notification information; if yes, perform base64 decoding processing on the custom cursor text content in the cursor shape notification information to generate the cursor type information in image format , to load the cursor data of the custom type; and update the cursor attribute information of the bound mouse according to the cursor shape information and the cursor type information.

The technical solution of the embodiment of the present invention is to remotely obtain the notification information of the cursor shape in real time through the client, decode it, and set the cursor shape of the client, so as to solve the problem that the client mouse pointer cannot display the content according to the page when the remote browsing service is currently implemented based on the pixel transmission method. The problem of real-time changes; especially suitable for the synchronization of the cursor shape of the client page when the cursor shape of the custom type is included.

Embodiment 2

FIG. 2a is a flowchart of a cursor shape synchronization method according to Embodiment 2 of the present invention. This embodiment can be applied to the situation where the client cursor pointer changes shape in real time with the cursor on the remote browsing server when the remote browsing service is implemented based on the pixel transfer method. And/or hardware implementation, the apparatus can be integrated in an electronic device, such as a remote browsing server device such as a cloud or a remote server.

Specifically, the cursor shape synchronization method provided in the second embodiment of the present invention can be applied to a remote browsing system, and is executed by a remote browsing server in the remote browsing system. The remote browsing system may be the same as the above-mentioned embodiment, and details are not repeated here.

As shown in Figure 2a, the method includes:

Step 210: After establishing the communication connection with the client, monitor the cursor shape change of the local browser.

The local browser of the remote browsing server can synchronize the access situation of the client, and when the cursor position changes, the cursor shape of the remote browsing server can dynamically change according to the content corresponding to the cursor position. The remote browsing server can monitor the cursor shape change in real time.

Step 220 , when the cursor shape of the local browser is monitored, generate cursor shape notification information, and publish the cursor shape notification information to the client, so that the client can synchronize the cursor shape.

The remote browsing server can generate cursor shape notification information according to the changed cursor shape when monitoring the change of the cursor shape of the local browser.

In an optional implementation of this embodiment of the present invention, when a change in the cursor shape of the local browser is monitored, generating cursor shape notification information includes: acquiring the target position and target content fed back by the client, and determining the target position and the target content according to the target position and the target content. Target content, determine the cursor shape information when the cursor shape changes; generate cursor shape notification information according to the cursor shape information.

The local browser of the remote browsing server can determine the target cursor shape corresponding to the target page content according to the target position and the target content. When the target cursor shape is inconsistent with the current cursor shape, it can be determined that the cursor shape is changed. The cursor shape information may be information corresponding to the target cursor shape. The remote browsing server can generate cursor shape notification information according to the cursor shape information.

On the basis of the above embodiment, optionally, after determining the cursor shape information when the cursor shape changes according to the target position and the target content, the method further includes: extracting the cursor type of the local browser; when determining that the cursor type is a custom type, extract the custom cursor image information of the local browser; perform base64 encoding processing on the custom cursor image information to generate custom cursor text content; generate cursor shape notification information according to the cursor shape information, including: according to the cursor shape information and Customize cursor text content and generate cursor shape notification information.

The remote browsing server can extract the cursor type from the cursor attribute information of the local browser. When the cursor type is a non-custom type, the remote browsing server can directly generate cursor shape notification information according to the cursor shape information. When it is determined that the cursor type is a custom type, the remote browsing server can extract the custom cursor image information of the local browser. The custom cursor image information may be cursor shape information customized by the website corresponding to the currently accessed page. Some personalized websites can embody custom cursors through pictures. The custom cursor image information can be reflected in the cursor attribute information of the local browser of the remote browsing server.

Exemplarily, FIG. 2b is a flowchart of a remote browsing server generating custom cursor text content according to Embodiment 2 of the present invention. As shown in Figure 2b, when the remote browsing server determines that the cursor type is a custom type, it can read the bitmap data of the custom cursor shape loaded by the local browser; convert the bitmap data to an image, such as converting it to Sklmage object; then encode the Sklmage object into a webp image, which can reduce the sending time of the image on the network while ensuring the quality of the image; finally, the webp image is base64 encoded to generate a custom cursor text content, which can be converted into binary encoding It is a visible character to avoid garbled characters during transmission.

In this embodiment of the present invention, the cursor shape notification information may include cursor shape information and custom cursor text content, which may specifically reflect the cursor shape and the custom type of the cursor, so that the client can perform indiscriminate cursor synchronization with the remote browsing server.

The technical solution of this embodiment is to monitor the change of the cursor shape of the local browser after establishing a communication connection with the client; when monitoring the change of the cursor shape of the local browser, generate cursor shape notification information, and send the cursor The shape notification information is released to the client, so that the client can synchronize the cursor shape, which solves the problem that the client cursor pointer cannot be changed in real time when the remote browsing service based on pixel transmission is currently implemented, and realizes the remote browsing service in the remote browsing system. The cursor shape of the client is synchronized to the client, and the client cursor can change its shape in real time with the remote browsing server, so as to achieve the effect that the client does not perceive the remote browsing access.

Fig. 2c is a flowchart of another cursor shape synchronization method provided by the second embodiment of the present invention. As shown in Fig. 2c, the use process of the cursor shape synchronization method provided by the present invention may be as follows: the remote browsing server can Monitor the cursor shape change of the browser; when monitoring the cursor shape change of the local browser, extract the cursor type of the local browser; determine whether the cursor type is a custom type; if not, generate the cursor shape according to the cursor shape information notification information, and publish the cursor shape notification information to the client, so that the client can synchronize the cursor shape; if so, extract the custom cursor image information of the local browser; perform base64 encoding processing on the custom cursor image information, and generate a custom cursor image information. Define the cursor text content; generate cursor shape notification information according to the cursor shape information and the custom cursor text content, and publish the cursor shape notification information to the client, so that the client can synchronize the cursor shape.
