Method for preventing repeat submission of page

Abstract

The invention relates to the technical field of computer application, and particularly relates to a method for preventing repeat submission of a page. The method includes steps of modifying a traditional Token mechanism; adopting a token object distributed in group, wherein every token object is corresponding to 1 url request, and all token objects form a token object group; then accumulating thesignal volume of token and comparing with 1; taking out the token group corresponding to the page from a serve before judging if it is repeatedly submitted; then judging if every object in the group and the token object of current request have the signal volume plus 1; if it is more than 1, regarding that the page is repeatedly submitted; terminating operation and returning wrong information prompt; if not, executing the business procedure, and finishing the detection. The token is generated through a form and cannot be modified; meanwhile, one token is corresponding to one request, the repeatsubmission of the whole page is controlled, thus infinite number of token groups can be placed; the method is simple and high-efficient, and able to effectively prevent the page from repeated submission.

Description

technical field [0001] The invention relates to the technical field of computer applications, in particular to a method for preventing repeated submission of pages. Background technique [0002] The Token (token) mechanism is adopted in the prior art scheme, and the principle is as follows: when accessing a request, the underlying framework puts a token (the so-called token is a randomly generated character string) into the session and stores it. Then turn to the page. The html:form tag in the page saves the token in the session to a hidden input field in the form form. When the user finishes entering the data and clicks save to execute the save request, the underlying framework will be in the business Before the program judges whether the token in the session is equal to the token in the hidden input field passed by the client, if they are equal, update the token in the session and execute the business program; when the system responds slowly, the user may It will click th...

Problems solved by technology

[0006] 3. When the page has an iframe (whether it is hidden or not), the cmd executed by the iframe will rewrite the token in the session, so that the homepage where the iframe is located cannot be submitted

[0007] 4. When multiple tab pages are used to display content on one page, and the user opens multiple pages, the newly opened page will modify the token in the session, causing the previously opened page to be unable to submit
