And the other participating terminals are terminals corresponding to the second user identifier, and the other participating terminals acquire and analyze the operation message and execute corresponding operations, for example, loading a next page of picture from the server for display.

According to the document sharing method, the operation instructions of the sharer terminal are collected and packaged into the operation messages, the operation messages are distributed to other participating terminals through the server, and the operation instructions comprise marks, so that the documents are paid and marked during document sharing, and the document sharing is more convenient.

FIG. 12 is a flow diagram of a document sharing method of an embodiment. The present embodiment is described by taking the method as an example applied to the first user terminal 101 shown in fig. 1. As shown in fig. 12, the method includes the steps of:

s102: sending a document sharing request to a server, wherein the document sharing request carries a document identifier, and acquiring a first storage address of a picture document corresponding to the document identifier on a storage platform by the server; the picture document is obtained by converting the document corresponding to the document identification into a picture format.

The document identification is a unique identification of the document, and can be a digest value of the document. When the terminal requests to upload the document, a data summarization algorithm is adopted to calculate the summarization value of the document, such as a hash algorithm, an MD5 algorithm and the like.

The server obtains a first storage address of the picture document corresponding to the document identifier in the storage platform, and sends the first storage address to the sharer terminal, that is, the first terminal in the embodiment, where the picture document is obtained after the document corresponding to the document identifier is converted into a picture format.

S104: and receiving the first storage address sent by the server.

S106: and downloading the picture document from the storage platform to the local according to the first storage address.

According to the document sharing method, a sharing request is sent to a server, the sharing request carries a document identifier, a first storage address of a picture document corresponding to the returned document identifier in a storage platform is obtained by the server, the picture document is obtained after the document corresponding to the document identifier is converted into a picture format, and the first storage address sent by the server is received; and downloading the picture document from the storage platform to the local according to the first storage address. Because the data volume of the picture is smaller than that of the video, the bandwidth and the flow occupied by document sharing can be saved. And meanwhile, a document sharing framework of the terminal, the server and the storage platform is formed, and by utilizing the picture document of the storage platform, the user can access at any place at any time by depending on the mobile device through data concentration, so that in-network resource sharing and cooperative work are realized, the traditional resource interaction is reduced, and the working efficiency is improved.

In another embodiment, the first storage address comprises an address of the first pictorial document and an address of the second pictorial document; and the pictures in the second picture document are thumbnails corresponding to the pictures in the first picture document.

Step S106 includes: and downloading pictures from the storage platform to the sharing display area for display according to the address of the first picture document, and downloading pictures from the storage platform to the directory list display area for display according to the address of the second picture document.

The thumbnail refers to a thumbnail obtained by compressing the first picture document. In a specific embodiment, the second storage address returned by the server is a list of URL addresses (Uniform resource locators) of the first picture document and the second picture document, and the URL addresses of the pictures are formed by splicing storage locations and page numbers.

In another embodiment, as shown in fig. 13, a document sharing method further includes S108 and S110:

s108: and collecting an operation instruction for the picture document, and packaging the operation instruction into an operation message, wherein the operation message carries the first user identifier.

Specifically, step S108 includes: collecting operation instructions of page turning/closing/zooming of the picture document, and packaging the operation instructions into operation messages.

Or, the step S108 includes the following steps S1 to S3:

s1: and collecting a marking instruction, wherein the marking instruction comprises marking parameters.

The marking parameters include the shape, size, color, etc. of the selected marking tool. The shape of the marking tool includes straight lines, circles, squares, and the like. The size refers to the width of the line of the formed mark, and the color refers to the color used for the mark. It will be appreciated that the system provides a mask for the user to select which parameters of the marking tool are preset, such as shape, size, color, etc.

S2: acquiring a starting point coordinate and an end point coordinate of the trigger operation in the first view relative to the second view; the first view is superimposed on a second view of the same size and same position for displaying the currently displayed picture in the shared display area.

The relative positional relationship of the first view and the second view is shown in fig. 14, the first view and the second view having the same size and the same position, the first view being superimposed on the second view. The first view is used for receiving mark triggering operation, such as triggering operation of a mouse or touch operation, and the second view is used for displaying a current display picture in the sharing display area.

Specifically, when the mouse is used for drawing and dragging, the first view can be continuously refreshed and redrawn, and the drawing effect can be seen. And when the mouse is lifted up, the starting point and the end point are removed, and at the moment, the first view is redrawn again, the drawn straight line disappears, and one-time complete marking operation is finished.

In consideration of the difference in coordinate systems of different platforms, the transmitted start point coordinate and end point coordinate in the present embodiment are relative coordinates with respect to the second view. Specifically, the start point coordinate and the end point coordinate are divided by the width and the height of the first view, respectively, for example, the width and the height of the first view displayed by the current picture are (100,200), the start point coordinate is (10,40), and the relative coordinate P (x, y) of the start point coordinate with respect to the second view is ((10.f/100.f), (40.f/200. f)). The difference in coordinate systems of different platforms also needs to be taken into account when encapsulating the start-point sitting and end-point coordinates. For example, in an IOS device, the origin of the view is in the upper left corner, while in a MAC device, the origin of the view is in the lower left corner. Therefore, it is necessary to reduce the vertical coordinates of the package coordinates of the MAC device. For example, in the MAC device, the relative coordinates P (x, y) of the start point with respect to the second view are ((10.f/100.f), 1- (40.f/200. f)).

S3: and packaging the marking parameters, the starting point seat identification and the end point coordinate into an operation message.

S110: and sending the operation message to a server, and sending the operation message to a terminal corresponding to a second user identifier with the same group identifier as the first user identifier by the server.

The sharer terminal system calls the mouse dragging event according to the refreshing frequency of the UI thread, and if the mouse dragging event is called each time, the data is sent again, so that greater data transmission pressure is brought to a network layer and a background. If the data is transmitted only once before the drawing is finished, the display of one mark disappears immediately after the audience receives the data, and the shared drawing and marking process cannot be seen completely. To this end, in another embodiment, the start point coordinate and the end point coordinate are start point coordinates and end point coordinates within a first preset time, and the step S110 includes: and sending the operation message to the server at intervals of a first preset time.

The first preset time in this embodiment is 0.1 second, that is, drawing data is collected and sent once every 0.1 second, which not only reduces the pressure on the network layer, but also enables the audience to completely see the drawing process.

The embodiment further provides a document sharing method, which is executed in the second user terminal 102 shown in fig. 1, and as shown in fig. 15, the method includes the following steps:

s302: and receiving a first storage address of the picture document in the storage platform, wherein the picture document is sent by the server and is obtained after the corresponding document is converted into a picture format.
