问题描述

YO


当我使用method =" POST";

$时，我得到（401）未经授权


b $ b

但是当我使用method =" PUT";


时它可以工作，但是asd.php无法使用


下面的代码我尝试了两种不同的方式

嗨


这是事实，我建议访问以下链接：

扩展代码 原因 描述
401.1 登录失败 网络服务器会将此声明为"HTTP错误401.1 - 未经授权：由于凭据无效而拒绝访问"和"b
401.2 由于服务器配置登录失败 您的Web浏览器和IIS服务器无法就身份验证协议达成一致。
Web服务器将此声明为"HTTP错误401.2 - 未经授权：由于服务器配置而拒绝访问。"
401.3 由于资源上的ACL而未经授权 服务器可以对您进行身份验证，但您没有足够的权限来访问所请求的内容。

I get (401) Unauthorized

when i use method = "POST";

but when i use method = "PUT";

it works, but asd.php cant use that

Hi

This are the fact, I would suggest to visit the link below:

http://support.microsoft.com/kb/907273

Extended code Reason Description
401.1 Logon failed The web server will announce this as “HTTP Error 401.1 - Unauthorized: Access is denied due to invalid credentials”
401.2 Logon failed due to server configuration Your web browser and the IIS server could not agree on an authentication protocol
The web server will announce this as “HTTP Error 401.2 - Unauthorized: Access is denied due to server configuration.”
401.3 Unauthorized due to ACL on resource The server could authenticate you, but you do not have sufficient permission to access the content requested.
The web server will announce this as “HTTP Error 401.3 - Unauthorized: Access is denied due to an ACL set on the requested resource.”
