奇怪的 403 禁止错误

Question

我在这里遇到了一个奇怪的情况。此错误仅出现在目录中的一个文件上，并且在提交表单时也会出现。它在我的机器上运行良好。但是服务器顽固地在表单提交时抛出错误！

错误：

Forbidden

You don't have permission to access /Myadmin/searchnsendmail2.php on this server.

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.
Apache/2.2.24 (Unix) mod_ssl/2.2.24 OpenSSL/1.0.0-fips mod_auth_passthrough/2.1 mod_bwlimited/1.4 FrontPage/5.0.2.2635 Server at www.landshoppe.com Port 80

代码在这里；

Answer 1

解决了！服务器似乎不喜欢 Textarea 值中的文本并提交了 html 字符！我删除了它们，现在一切都好！谢谢大家！

我还想借此机会强调一个事实，即每当我在谷歌上搜索这个问题时，我总是发现有人说这是一个权限问题。太令人沮丧了，因为我无法理解为什么突然只有一个文件和一个表单出现权限问题。我希望我的这个例子能让所有对这个问题感到沮丧的人（以及那些提供权限问题作为答案的人）知道它也可能是我的错误并调查它。应该为很多人节省很多时间！

Answer 2

遇到了同样的错误，但它是由表单长度引起的。我有一个包含数百个字段的表单。删除一些字段后，表单提交成功。

表单长度触发了关于 mod_security 的规则。我的应用程序位于共享主机上，因此向主机提供商提出绕过规则的简单请求即可解决问题。

Answer 3

我只是在提交包含表单的 php 页面时间歇性地遇到此错误...在我的情况下，问题是服务器上的完整 /tmp 目录。在此处发布此内容以防对其他人有所帮助。
