Detailed Description

Exemplary embodiments of the present invention are described below with reference to the accompanying drawings, in which various details of embodiments of the invention are included to assist understanding, and which are to be considered as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.

Fig. 1 is a schematic flow chart of a cloud document processing method according to an embodiment of the present invention. A cloud document processing method is applied to a client, and at least comprises the following operation flows:

s101, sending an editing request of the cloud document, so that the server side selects target content from the cloud document and encrypts the target content.

Here, the target content refers to a part of content in the cloud document.

S102, receiving and storing the encrypted target content.

S103, reading the stored target content and inserting the target file.

Illustratively, determining whether to create a new file and insert the stored target content; if so, creating a new file, and taking the created new file as a target file; reading the stored target content and inserting the read target content into a target file; if not, selecting a target file from the candidate files, reading the stored target content and inserting the read target content into the target file.

The client can read the stored target content in many ways, for example, via a communication protocol. Reading the stored target content and inserting the read target content into the target file can be realized by the following steps: and acquiring a key of the target content from the server, decrypting the stored target content according to the key, and inserting the decrypted target content into the target file.

It should be noted that before creating a new file, the file type of the new file needs to be further determined; a new file corresponding to the file type is created. The candidate file is a file existing in the client, and the target file is a file which needs to be edited currently by the user.

S104, acquiring the request of finishing the interaction, and deleting the stored target content.

Here, the interaction ends in a manner of closing the browser of the client or exiting the operation right of the client.

In the prior art, when a client edits a ppt, an excel chart of a cloud document is needed, and the excel chart on the cloud document is copy and paste prohibited, but the method is very time-consuming if data of the excel chart is input in the ppt. For this reason, the client side of the embodiment first obtains a cloud document editing request of a user, and then sends the cloud document editing request to the server side, for example, the editing request is mainly a request for editing target content in the cloud document. The server side selects target content corresponding to the editing request from the cloud document according to the editing request, encrypts the target content, and sends the encrypted target content to the client side. The client receives the encrypted target content and then stores the encrypted target content, and generates a trigger instruction; the client responds to the trigger instruction, reads the stored target content, and the reading process is to decrypt the stored target content; the decrypted target content is then inserted at the specified location of the target document. When the target document is edited online and the client acquires an instruction for closing the online browser, deleting the stored target content; for example, a link address is corresponding to the client, and an authorized user can remotely control the client by using a virtual machine through the link address, and the closing of the online browser of the client is realized by closing the virtual machine or disconnecting the link address. When the client deletes the stored target content, the target content is invalid.

It should be appreciated that in this embodiment, the client need not maintain a target document carrying the target content.

According to the embodiment of the invention, the target content of the cloud document is encrypted by the server and then sent to the client, and the stored target content is deleted by the client after the target document is edited, so that the safety of the content of the cloud document is ensured.

Fig. 2 is a schematic flow chart of a cloud document processing method according to another embodiment of the present invention. A cloud document processing method is applied to a client, and at least comprises the following operation flows:

and S204, storing the target file carrying the target content and sending the target file to the server so that the server stores the target file carrying the target content.

Specifically, the client analyzes the target file carrying the target content into json for storage, and then sends the message corresponding to the json to the server.

S205, the request for finishing the interaction is obtained, and the stored target content and the target file carrying the target content are deleted.

The specific implementation processes of steps S201, S202, and S203 are similar to the specific implementation processes of S101, S102, and S103 in the embodiment shown in fig. 1, and are not described herein again.

According to the embodiment of the invention, the target file carrying the target content is sent to the server side for storage, so that the target file can be reused conveniently, and the convenience of using the cloud document information is improved. When the interaction is finished, the target file carrying the target content and stored in the client is deleted, so that the risk of leakage of the decrypted cloud document content is reduced, and the safety of the target content in the cloud document is improved.

Fig. 3 is a schematic flow chart of a cloud document processing method according to another embodiment of the present invention. A cloud document processing method is applied to a server side and at least comprises the following operation flows:

s301, receiving an editing request of the cloud document.

S302, according to the editing request, target content is selected from the cloud document and encrypted.

S303, sending the encrypted target content, so that the client reads the encrypted target content and inserts the read target content into the target file.

Fig. 4 is a schematic flow chart of a cloud document processing method according to still another embodiment of the present invention. A cloud document processing method at least comprises the following operation flows:

s401, the client sends an editing request of the cloud document to the server.

S402, the server side selects target content from the cloud document according to the editing request and encrypts the target content.

S403, the server sends the encrypted target content to the client.

S404, the client stores the encrypted target content.

S405, the client reads the stored target content and inserts the target file.

Specifically, after the server sends the encrypted target content, a password request of the target content is received; and determining a password corresponding to the target content according to the password request, and then sending the password to the client so that the client can read the encrypted target content.

S406, the client stores the target file carrying the target content.

S407, the client sends a target file carrying the target content to the server.

S408, the server stores the target file.

S409, the client side obtains the request of finishing the interaction, and deletes the stored target content and the target file carrying the target content.
