我正在尝试对authentication.asmx Web服务进行身份验证。
在visual studio中，我右键单击我的项目并单击“添加服务引用”。
我在我的地址中输入以下内容：
https://my-domain.com/sp/testsite/_vti_bin/Authentication.asmx
然后点击“开始”按钮。然后我得到以下错误。我可以通过浏览器访问网络服务，但没有任何问题，所以不确定我做错了什么。
The document at the url https://my-domain.com/sp/testsite/_vti_bin/Authentication.asmx was not recognized as a known document type.
The error message from each known type may help you fix the problem:
- Report from 'https://my-domain.com/sp/testsite/_vti_bin/Authentication.asmx' is 'The document format is not recognized (the content type is 'text/html; charset=utf-8').'.
- Report from 'DISCO Document' is 'There was an error downloading 'https://my-domain.com/_vti_bin/Authentication.asmx?disco'.'.

If the service is defined in the current solution, try building the solution and adding the service reference again.
