Method and device for submitting online examination data

Abstract

The invention discloses a method and device for submitting online examination data. The method includes entering an online examination system by a user; initializing a stack manager; answering test questions; judging whether current test questions are answered for the first time, and if yes, creating a stack and a timer for the test questions; otherwise, updating stack data; when the timer reaches a time interval threshold value and answering records exist in the stack, submitting the answering records in the stack to a server side; after the user answers all the test questions, clicking to submit test papers; traversing a stack list in the stack manager, finding the answering records that are not submitted yet, submitting to the server side, and completing updating of the answering records of all the test questions; closing a timing task, and destroying the stack manager; and completing test paper submission. The method provided by the invention can effectively prevent the user from frequent modification of answering results or vicious submission operation, minimizes requests to the server side, reduces concurrent pressure of the server side, and can effectively guarantee accuracy of online examination performance of the user.

Description

Technical field [0001] The invention relates to the field of online examinations, in particular to a method and device for submitting online examination data. Background technique [0002] Online examination refers to a form of examination in which the examination process is conducted on the network media through a computer. Because a computer failure or network abnormality will cause the user to experience an abnormal interruption during the examination process, it is necessary to record the user’s examination process in real time to facilitate the examination. When an interruption occurs, the user's answer record can be quickly restored to ensure the accuracy of the user's online test results. [0003] When traditional online exams record user answer data in real time, they usually record the answer data information in real time when the user modifies the answer, but this will cause a sharp increase in http requests to the server, and there may be users who can quickly switch ans...

Problems solved by technology

Although this method can prevent malicious attacks on the service caused by rapid switching of answer options, it is only a temporary solution, not the root cause. First of all, if the threshold is set too short, the request will not be reduced, because every time the answer record is updated, all test questions need to be submitted. Answer data, if there is too much question data, the request will not be reduced at this time, and the risk of large concurrency will increase. Secondly, if the threshold is set too large, the recorded answer data will be inaccurate
