调试403错误 [英] Debug a 403 error

问题描述

具有SSL证书的域（ https://www.example.com/form.html ）上的简单html表单定义如下：

< form method =postaction =https://www.example.com/processForm.php>

当我发布表单时，我收到了一条403错误消息

我已经广泛搜索了解决方案。我发现：

• 表单内容中的网址应该被编码


• 可能有权限需要解决的问题 .htaccess


• 表单方法属性可能不正确


• action属性可能是错误的（例如，缺少 www。）
  

我已经检查了上述每一项，但没有解决问题。

可能存在403错误的其他原因？

解决方案

您的目标网址可能需要CSRF令牌才能防止跨网站请求伪造。请阅读 https://www.owasp.org/index.php/ Cross-Site_Request_Forgery_％28CSRF％29

A simple html form on a domain with an ssl certificate (https://www.example.com/form.html) is defined like this:

<form method="post" action="https://www.example.com/processForm.php">

When I post the form I get a 403 error message

I have searched extensively for solutions. I found that:

• urls in the form content should be encoded
• there might be a permission problem to be resolved in .htaccess
• form method attribute might be incorrect
• action attribute might be erroneous (for example missing the www.)

I have checked each of the above and not fixed the problem.

What other reasons may exist for a 403 error?

解决方案

Your target url may required a CSRF token to prevent Cross-Site Request Forgery. Read more at https://www.owasp.org/index.php/Cross-Site_Request_Forgery_%28CSRF%29
