A method of controlling the number of times a page is previewed, comprising:
after uploading the file to a computer, a user inputs a parameter to a server, wherein the parameter is the number of times the file is allowed to be previewed;
the background program acquires the parameters and allocates a unique address to the file, the parameters are stored in the address, the background program generates a preview link corresponding to the file, and the unique address and the preview link are stored in a server side;
when a user previews a file through the preview link, the background program analyzes a file address through the preview link, the server records the previewed times of the file, and if the previewed times are larger than the value of the parameter, the file is limited to be previewed by the server.
In one embodiment, a user sends a preview limiting request to a background program by inputting parameters, and the background program receives the preview limiting request and acquires the parameters;
and the background program allocates a unique address to the uploaded file according to the acquired parameters, and the address records the allowed preview times of the file set by the user.
In one embodiment, the daemon establishes an association between the generated preview link and a unique address allocated to the uploaded file, and stores the established association in a server side at the same time.
In one embodiment, a user opens a preview link on computer equipment, and a background program acquires an address of the preview link and analyzes the unique address of the preview corresponding to the preview link;
and the background program inquires the file address recorded by the server side and the allowable preview times of the file.
In one embodiment, the server records the previewed times of the file, the previewed times are increased along with the times of the file being opened, the background program compares the previewed times with the allowable previewing times of the file, and if the previewed times are greater than the allowable previewing times, the file is limited to be previewed by the server.
Aiming at the premise that a user has a safety requirement on the link and the resource of the preview document, if the preview link and the resource are required to be only allowed to be accessed once, namely, the preview link and the resource are burnt after reading, the user hopes to carry out the operation of destroying after reading aiming at part of files containing privacy or important contents, and the method for controlling the page previewing frequency can effectively solve the problem when the safety requirements such as confidentiality and the like are met.
The method for controlling the page previewing times is mainly characterized in that a background program inquires a file address (id) recorded by a server side and information of allowed previewing times, and the previewing times are compared with the previewed times to control the file previewing times, so that the server side is closed at regular time.
The previewing times are increased along with the previewing times of the user, the user previews the previewed times once, the server records the value of the unique id and the previewed times once, the previewed times are increased by one, then whether the previewed times are legal or not is judged by comparing the recorded previewed times with the allowed times set at the beginning, if the previewed times are smaller than or equal to the allowed times, the previewed times are legal, otherwise, the previewed times are illegal, normal resource information is returned, the illegal situation prompts the user that the link is overdue, and when the user requests the link, the background adds one to the unique id.
Referring to fig. 1-3, a user sets an allowed preview time to be 1, when a server generates a preview web page file, the server records the preview time according to the unique id of the file, when the user previews the web page content, the time is increased by 1 (see fig. 2, the preview is successfully opened for the first time), until the time is greater than a set value, the user directly stops obtaining the preview content, and when the user refreshes a browser, the server does not preview the content for the client any more because of the time limitation (for example, fig. 3, the preview fails to be opened for the second time).
Referring to fig. 4-7, the user sets the allowed preview number to be 2, when the server generates a preview web page file, the server records the preview number according to the unique id of the file, when the user previews the web page content, the number of times is increased by 1 (see fig. 5 and 6, the first time and the second time of opening the preview are both successful), until the number of times is greater than the set value, the user directly stops obtaining the preview content, when the user refreshes the browser, the server does not preview the content to the client any more because of the number limitation (for example, fig. 7, the third time of opening the preview fails), so that the accuracy of the recorded number of times and the security of the file are greatly guaranteed.
In summary, the invention provides a method for controlling the number of times of previewing a page, which realizes that a server side sets the number of times of previewing a file, when a browser previews the file, the page access is controlled according to the access number set by the server side, once the number of times of previewing exceeds the number of times of previewing, the function can realize that the file is burnt after being read, and the information security is ensured.
