在开发用于基本身份验证的 IIS 模块期间,我遇到了一个问题。该模块在浏览页面时工作正常,但是在调用 Web 服务时,请求似乎没有到达该模块,并且一些中间模块控制了请求。
使用提琴手,我发现Content-type
在 http 请求头设置为application/json
中间模块/处理程序时触发。所以以下请求不起作用:
WWW-Authenticate
正常工作时,服务器应通过设置响应头来要求客户端发送用户凭据
GET /WebServices/service.asmx/someMethod?param=test HTTP/1.1
Host: localhost
Connection: keep-alive
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.22 (KHTML, like Gecko) Chrome/25.0.1364.152 Safari/537.22

Accept-Language: en-US,en;q=0.8
Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.3
Content-Type: application/json
asdfasdf
asdfasdfasdf
响应:注意响应中的jsonerror标头
HTTP/1.1 401 Unauthorized
Content-Type: application/json; charset=utf-8
Server: Microsoft-IIS/7.5
jsonerror: true

{"Message":"Authentication failed.","StackTrace":null,"ExceptionType":"System.In
validOperationException"}
这个工作正常的地方:注意没有content-type
GET /WebServices/service.asmx/someMethod?param=test HTTP/1.1
Host: localhost
Connection: keep-alive
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.22 (KHTML, like Gecko) Chrome/25.0.1364.152 Safari/537.22
Accept-Encoding: gzip,deflate,sdch
Accept-Language: en-US,en;q=0.8
Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.3
asdfasdf
asdfasdfasdf
正确的响应是:注意响应中的WWW-Authenticate
标头
HTTP/1.1 401 Unauthorized
