AnQiCMS Verification Code: A strategy to parse the effective identification and prevention of automated tools from submitting forms
In the wave of digitalization, website security and content purity are the focus of operators.With the development of Internet technology, the activity of automated tools (Bot) is increasing day by day. They submit spam comments, malicious registrations, and flood messages in bulk, which not only consume server resources and pollute data but may also damage the brand image and user experience of the website.As a senior website operations expert, I fully understand the importance of a robust content management system in mitigating such threats.AnQiCMS, relying on the efficient characteristics of the Go language and its emphasis on security, provides an effective captcha mechanism in dealing with automated tool form submission.
AnQiCMS as an enterprise-level content management system developed based on the Go language, has high performance and security as its core advantages from the bottom-up architecture.Its design philosophy is to provide a stable, efficient and secure operation platform for small and medium-sized enterprises, self-media operators, and others.Facing the challenges of automated tools, AnQiCMS does not just stop at basic firewalls or IP restrictions, but delves into the form submission process. By introducing captcha, this classic and effective anti-bot and anti-spam mechanism, it performs intelligent recognition and interception at the user behavior level.
How does AnQiCMS's captcha mechanism effectively identify and prevent automated tools from submitting forms?This is mainly reflected in the convenience of its background configuration and the flexibility of front-end template integration.
Firstly,Enable captcha functionIs the first step of defense.The website administrator only needs to log in to the AnQiCMS backend management system, check the option to enable captcha in relevant settings (such as message management or comment management module).This operation will activate the system-built captcha generation and verification service, laying a foundation for the secure submission of subsequent forms.
Next,Skillful integration of front-end templatesIs the core to implement the captcha function.The reason why automated tools can submit forms in batches largely lies in their ability to directly parse HTML code and simulate HTTP requests.
- Dynamic captcha image and unique identifierIn a form that requires captcha, such as a message form or comment form, AnQiCMS requires integrating an image tag (
<img>To display the captcha, as well as two key hidden or text input fields:captcha_idandcaptcha.captcha_idIs a unique identifier generated by the server, used to track the session state of the current captcha;captchaField is used for users to input the content of the verification code they recognize. - JavaScript dynamic loading and refreshing：Verification code image is not statically hardcoded on the page, but is generated through front-end JavaScript code,
/api/captchaThis dynamic interface initiates a request to obtain JSON data containingcaptcha_idThis JavaScript will handlecaptcha_idFill in the hidden field and set the URL of the obtained captcha image to<img>TagssrcProperties. What's more, users can trigger the same JavaScript function by clicking on the captcha image to refresh the captcha, obtaining a new image andcaptcha_id. - Front-end and back-end collaboration verificationWhen the user submits the form, in addition to the other data of the form,
captcha_idand the value entered by thecaptchauser will also be submitted to the server. The backend of AnQiCMS will be based oncaptcha_idFind the corresponding verification code session and compare it with the user's input.captchaIs it correct. Only when both of these match will the form data be considered a valid submission and processed by the system.
The ingenious aspect of this mechanism lies in its utilization of the differences between humans and automated programs in recognizing image text.For human users, recognizing characters in images and inputting them, refreshing unclear captcha, are all simple operations.captcha_idEven if there are more complex Bots trying to simulate, the cost and complexity will increase greatly.
Through such captcha integration strategy, AnQiCMS can effectively reduce spam submissions from automated tools.This not only helps maintain the cleanliness of the website content, reduce the operating pressure of the server, but also ensures the quality of the website data, allowing operators to focus on truly valuable user interactions and content management.
AnQiCMS not only provides powerful content management capabilities, but also builds a solid defense line for operators in terms of security.Its captcha function is an important part of its overall security strategy, aiming to provide users with a stable, pure and easy-to-manage website environment.
Common Questions (FAQ)
1. Can AnQiCMS's captcha be applied to all types of forms on a website?
Currently, the captcha function of AnQiCMS is mainly designed to protect modules such as comment forms and message forms that are prone to attacks by automated tools.These are the most common garbage information submission entry points on the website.If you have other custom form validation requirements, you may need to combine custom development or consider integrating a third-party advanced validation service.
2. If the user cannot recognize the characters in the captcha image, does AnQiCMS provide a solution?
Yes, AnQiCMS's captcha mechanism takes this into account. When integrating the captcha on the front-end, users can refresh the captcha image by clicking on it, and the system will generate a new captcha image and correspondingcaptcha_id. So, if the current captcha is difficult to recognize, users can easily obtain a new one to try, thus optimizing the user experience.
3. Besides the captcha, does AnQiCMS have other mechanisms to prevent automated tools (Bot) from submitting?
AnQiCMS was designed with website security in mind from the beginning.In addition to the captcha, the system also includes features such as "anti-crawling interference code", which is used to protect original content from malicious scraping.Moreover, its high-performance architecture based on Go language itself can better resist high concurrency attacks, and in conjunction with content security management and sensitive word filtering functions, they together build a multi-level security protection system for the website.
