Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1a is a flowchart of a cursor shape synchronization method according to an embodiment of the present invention, where this embodiment is applicable to a case where a cursor pointer of a client performs a shape change in real time with a cursor of a remote browsing server when a remote browsing service is implemented based on a pixel transfer manner, and the method may be executed by a cursor shape synchronization device, where the cursor shape synchronization device may be implemented in a software and/or hardware manner, and the cursor shape synchronization device may be integrated in an electronic device, such as a mobile phone or a computer.
Specifically, the cursor shape synchronization method provided in the embodiment of the present invention may be applied to a remote browsing system, and executed by a client in the remote browsing system. The remote browsing system can realize remote browsing service based on pixel transmission mode. The remote browsing system can comprise a client and a remote browsing server. The client can access the Web browser content of the remote browsing server in a remote browsing mode. The client does not have interface generation content of the Web browser accessed remotely, such as a hypertext transfer protocol and a form required by Web page formation, so that the client can be prevented from being attacked, and the loss of a user is avoided. The client can be understood as a remote display interface for remotely browsing the contents of the server page. The remote page content displayed at the client may be understood as a picture, and when the cursor moves on the remote page content, the shape of the cursor does not change, for example, the cursor of the client is fixedly displayed as an arrow pointer. The access remote browsing server can be a cloud terminal or a remote server and other terminals, the attack risk borne by the client can be reduced through a remote browsing mode, the attack objects are reduced, and resources are protected.
As shown in fig. 1a, the method specifically includes:
and step 110, after communication connection with the remote browsing server is established, acquiring cursor attribute information of the local browser, and performing information binding.
The client and the remote browsing server are respectively provided with a local browser. The local browser of the client can realize the basic access of the client to the browsing. The local browser of the remote browsing server can realize the remote access of the client to the browsing. The cursor shape of the client can be changed through the style interface of the local browser. In the embodiment of the invention, the client can bind the cursor attribute information of the local browser so as to realize the synchronous and remote cursor shape browsing through the style interface of the local browser. The cursor may be understood as a pointing indicator of the client, for example, the cursor may be a pointing indicator displayed on the display interface by a mouse.
Specifically, the Cursor attribute information of the local browser is obtained, and the information binding may be performed by binding a Cursor attribute in a Cascading Style Sheet (CSS) of the local browser on a canvas of the client. The Cursor property may determine the Cursor shape that appears when within certain element boundaries, such as question marks, handlets, crosses, arrows, movement markers, text markers, busy markers, and the like.
And step 120, acquiring cursor shape notification information issued by the remote browsing server, and processing the cursor shape notification information to obtain cursor shape information.
The cursor shape notification information may include cursor shape information, among others. For example, the cursor shape notification information may be a concrete representation of the processed cursor shape information. Alternatively, the cursor shape notification information may include cursor shape information and other ancillary information. The processing of the cursor shape notification information may be a process of parsing or decoding the cursor shape notification information, or the like, thereby extracting key information such as cursor shape information. The cursor shape information may be a concrete representation 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 cursor shape notification information issued by the remote browsing server, the method further includes: and determining the target position of the current cursor and the target content matched with the target position, and feeding back the target position and the target content to the remote browsing server.
The target position may be a page position where the cursor is located when the client performs remote browsing. The target content may be content in the page that matches the target location. For example, the target position of the cursor is the third row and the fourth word of the page position. The target content matched with the target position is hyperlink content. The remote browser server side can perform position synchronization with the target position of the cursor of the client side, and determine the content type to which the target content matched with the target position belongs, so that the cursor shape is determined according to the content type. For example, the cursor shape corresponding to the hyperlink content is a little hand; seeking a cursor shape corresponding to the help content as a question mark; the cursor shape corresponding to the text content is a text identifier, and can indicate that the current content of the client user can be selected, copied and the like. 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.
And step 130, updating the bound cursor attribute information according to the cursor shape information, and synchronizing the cursor shape.
The client can present the cursor shape according to the updated cursor attribute information, so that the cursor shape of the client is consistent with that of the remote browsing server, namely, the cursor shape is synchronized.
In an optional implementation manner of the embodiment of the present invention, after processing the cursor shape notification information to obtain the cursor shape information, the method further includes: determining the type of the cursor according to the cursor shape notification information; and when the cursor type is the custom type, performing base64 decoding processing on the custom cursor text content in the cursor shape notification information, and generating cursor type information in an image format. Updating the bound cursor attribute information according to the cursor shape information, and performing cursor shape synchronization, wherein the cursor shape synchronization comprises the following steps: and updating the bound cursor attribute information according to the cursor shape information and the cursor type information, and synchronizing the cursor shape.
The cursor shape possibly 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 the embodiment of the present invention, it may be determined whether the cursor type is a custom type. If the cursor type is the custom type, the cursor shape under the custom type can be updated, so that the cursor shape of the client side is completely consistent with that of the remote browsing server side.
Specifically, the cursor shape notification information issued by the remote browsing server may include custom cursor text content. If the cursor type is a non-custom type, i.e. a default cursor type, the custom cursor text content may be null data or other forms of data representing the default cursor type. If the cursor type is the self-defined type, the self-defined cursor text content can be information related to the self-defined cursor image information under the self-defined type. The user-defined cursor image information can be specific image information of one or more user-defined cursor shapes in a user-defined type. For example, the custom cursor image information may include image information of a green little hand; or image information of a rose text logo, etc.
In the embodiment of the invention, in order to avoid the situations of data loss or data messy codes and the like when the user-defined cursor image information is transmitted between the remote browsing server side and the client side, the user-defined cursor image information can be coded. For example, the user-defined cursor image information can be changed into text information for transmission, so that the transmission of visible characters is realized, and the problem of messy codes is avoided. Therefore, in the embodiment of the present invention, the custom cursor text content may be a content generated by the remote browsing server by performing base64 transcoding on the custom cursor image information. Specifically, the self-defined cursor image information originally coded through binary can be converted into text content through base64 coding, transmission can be facilitated, and messy codes are avoided.
In the embodiment of the present invention, when the cursor type is the custom type, the client may 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 may be in JSON format. The JSON format is a data standard format in network communication, and can facilitate the client to perform cursor shape synchronization.
In an optional implementation manner 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 type in the bound cursor attribute information according to the cursor type information, and synchronizing the cursor type; and under the cursor type, updating the cursor shape in the bound cursor attribute information according to the cursor shape information, and synchronizing the cursor shape under the cursor type.
The client can determine the cursor name corresponding to the user-defined cursor image information corresponding to the user-defined 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, and the synchronization of the cursor type is realized. Further, under the cursor type, specific cursor shape synchronization can be performed.
Illustratively, the default hyperlink content corresponds to a cursor shape that is a white little hand, while the custom type hyperlink content corresponds to a cursor shape that is a green little hand. In the embodiment of the invention, the cursor attribute information can be updated into a custom type corresponding to green through cursor type synchronization; and then, carrying out cursor shape synchronization, and updating the cursor attribute information into green little hands in a custom type corresponding to green. Therefore, the cursor shape synchronization under the cursor type is realized, the cursor shape synchronization of the remote browsing page under the user-defined type can be realized, and the remote browsing access without perception of the client user is realized.
According to the technical scheme of the embodiment, after the communication connection with the remote browsing server is established, the cursor attribute information of the local browser is acquired, and the information binding is carried out; acquiring cursor shape notification information issued by a remote browsing server, and processing the cursor shape notification information to obtain cursor shape information; the method has the advantages that the bound cursor attribute information is updated according to the cursor shape information, the cursor shape synchronization is carried out, the problem that a client cursor pointer cannot change in real time when the remote browsing service is realized based on a pixel transmission mode at present is solved, the cursor shape of a remote browsing server in a remote browsing system is synchronized to a client, the client cursor can change in real time shape along with the remote browsing server, and therefore the effect that the client does not sense remote browsing access is achieved.
Specifically, fig. 1b is a flowchart of another cursor shape synchronization method according to an embodiment of the present invention. As shown in fig. 1b, a specific application process of the cursor shape synchronization method provided by the embodiment of the present invention may be: the client side initiates a remote browsing access request to the remote browsing server side, and the client side and the remote browsing server side establish a remote browsing session; the client binds the cursor attribute of the mouse on the canvas of the client; the client acquires cursor shape notification information issued by a remote browsing server in real time; when the cursor shape notification information is acquired, judging whether the cursor type is a user-defined type according to the cursor shape notification information; if not, updating cursor attribute information of the bound mouse according to the cursor shape information in the cursor shape notification information; if so, carrying out base64 decoding processing on the self-defined cursor text content in the cursor shape notification information to generate cursor type information in an image format, and realizing the loading of the cursor data in the self-defined type; and updating cursor attribute information of the bound mouse according to the cursor shape information and the cursor type information.
According to the technical scheme of the embodiment of the invention, the client-side remotely obtains the cursor shape notification information in real time, decodes the cursor shape and sets the cursor shape of the client-side, so that the problem that a mouse pointer of the client-side cannot change in real time according to the display content of a page when the remote browsing service is realized based on a pixel transmission mode at present is solved; the method is particularly suitable for the synchronization of the client page cursor shape when the user-defined type cursor shape is included.

When the target cursor shape is not consistent with the current cursor shape, it may be determined that the cursor shape has changed. The cursor shape information may be information corresponding to a target cursor shape. The remote browsing server side can generate cursor shape notification information according to the cursor shape information.

When the cursor type is a non-self-defined type, the remote browsing server side can directly generate cursor shape notification information according to the cursor shape information. When the cursor type is determined to be the custom type, the remote browsing server can extract the custom cursor image information of the local browser. The user-defined cursor image information can be cursor shape information defined by a website corresponding to the currently accessed page. Some personalized websites may embody a custom cursor through a picture. The user-defined cursor image information can be embodied in the cursor attribute information of the local browser of the remote browsing server.
Fig. 2b is a flowchart of generating a custom cursor text content by a remote browsing server according to a second embodiment of the present invention. As shown in fig. 2b, when determining that the cursor type is the custom type, the remote browsing server may read bitmap (bitmap) data of the custom cursor shape loaded by the local browser; performing image conversion on the bitmap data, such as converting the bitmap data into a Sklmage object; the Sklmage object is coded into a webp image, so that the sending time of the image on the network can be reduced while the image quality is ensured; and finally, performing base64 coding processing on the webp image to generate self-defined cursor text content, converting binary codes into visible characters, and avoiding the problem of code disorder during transmission.
