The core technical idea of the application is as follows: the time limit is added to the validity of the verification code, and the verification code is a short video, namely, the user must watch the short video, answer the content related to the short video, and the verification is calculated after the answer is correct. The malicious program can be effectively prevented from capturing the content of the verification code, realizing automatic login, malicious watering, malicious access increasing and other actions.
The following expansion description:
step S101: responding to a verification code request instruction, and returning a preset verification code to a front-end page, wherein the preset verification code comprises: short video and problem module.
Step S102: responding to the video playing instruction, and judging whether the user answers the questions of the question module correctly within the preset time after the video is played; the questions of the question module are related to the content of the short video.
A webpage verification generation method based on a preset video comprises the following steps: responding to a verification code request instruction, and returning a preset verification code to a front-end page, wherein the preset verification code comprises: a short video and question module; responding to the video playing instruction, and judging whether the user answers the questions of the question module correctly within the preset time after the video is played; the questions of the question module are related to the content of the short video. The content of the verification code is displayed in a video mode, a user needs to click and watch the verification code and then obtain a correct answer by combining the content, pick the correct answer and submit the verification, and actions such as capturing the content of the verification code by a malicious program, realizing automatic login, malicious watering, malicious access and the like can be avoided to a large extent.
In this embodiment, the front-end page is presented in a visual interface form, the user clicks a verification code acquisition button, and sends a session request for generating a verification code to the background, and the background responds to a verification code request instruction, where "return a preset verification code to the front-end page, and the preset verification code includes: short video and question module ", comprising the steps of: randomly selecting short video files (preferably 5-10s in time length) preset in a database, and a question module, wherein the question module comprises: question descriptions, option lists, and whether to multi-select modes related to the content of the short video.
And after the front-end page receives the preset verification code returned by the background, displaying the problem description, the short video and the option list on the front-end page. The front-end page renders different option list styles according to whether a multi-selection mode is adopted, the multi-selection mode displays a multi-selection frame, and a non-multi-selection mode displays a single-selection frame.
At this point the countdown of the preset time begins, such as 60 seconds. After the video is played, if the user answers the questions before the countdown is finished, the verification is passed.
