调用web services提示Access Denied的解决办法[整理]

现象:

asp.net中调用web services时提示错误:

请求因 HTTP 状态 401 失败：Access Denied。

将web services放到另一台服务器问题又不存在该问题。

解决办法:

1.新建方法:

#region GetCredentialCache

/// <summary>

/// 获取CredentialCache

/// 解决访问web service时提示没有权限的问题

/// </summary>

/// <returns></returns>

public static CredentialCache GetCredentialCache()

{

//权限验证web services地址

string WSUrl = RightsServicesUrl;

//Create an instance of the CredentialCache class.

CredentialCache cache = new CredentialCache();

// Add a NetworkCredential instance to CredentialCache.

// Negotiate for NTLM or Kerberos authentication.

cache.Add( new Uri(WSUrl), "Negotiate", new NetworkCredential("域用户名", "域密码", "域"));

return cache;

}

#endregion

2.为web services指定CredentialCache

web services引用名为RightsControl，添加如下代码：

RightsControl rightsControl = new RightsControl();

//为web services指定CredentialCache,最重要的就是这一句

rightsControl.Credentials = GetCredentialCache();

//调用rightsControl的方法
