摘要
建设社会各方资源的协同学习型平台在开放大学办学中有非常重要的意义。验证码技术可以为平台构建保驾护航。PHP作为一种web编程语言,可以创建和输出多种格式的图像。结合PHP程序特点,生成验证码,输出干扰曲线、背景以及干扰字符。对PHP生成验证码进行类实例化,在视图中调用,通过异步方式完成对输入验证码表单的验证,有效防止非法用户对平台注册用户的跨站攻击和暴力破解。
The construction of collaborative learning platform for all resources in society is of great significance in the process of the transformation of open universities. The verification code technology to build the escort for the platform effectively prevents the illegal users＇ XSS attack and brute force against the platform＇s registered users. PHP, as a web programming language, can create and output images in a variety of formats. By using the advantages of PHP program, the PHP program is enhanced, the function of the generated image data output verification is instantiated, and the verification code output to the browser is completed in the form verification.
