Question

我正在尝试通过在SOAP标头中传递用户凭据来验证对WCF Web服务的外部请求。

using (UsrService client = new UsrService())
{
    client.Credentials = new System.Net.NetworkCredential("User 1", "Password 1");
    client.SomeRemoteMethod();
}

我得到例外：

未处理的异常：System.Net.WebException：请求失败错误消息：对象已移动

Unhandled exception: System.Net.WebException: The request failed with the error message:

以下列方式制作。

通过使用传输协议，我发送了用户凭据，如下所示：

public const string authServiceUri = "http://localhost:8080/ServiceModel/AuthService.svc/Login";
public static CookieContainer AuthCookie = new CookieContainer();

public static bool TryLogin(string userName, string userPassword)
{
    var authRequest = HttpWebRequest.Create(authServiceUri) as HttpWebRequest;
    authRequest.Method = "POST";
    authRequest.ContentType = "application/json";
    authRequest.CookieContainer = AuthCookie;

    using (var requesrStream = authRequest.GetRequestStream())
    {
        using (var writer = new StreamWriter(requesrStream))
        {
            writer.Write(@"{
                ""UserName"":""" + userName + @""",
                ""UserPassword"":""" + userPassword + @"""
            }");
        }
    }

    using (var response = (HttpWebResponse)authRequest.GetResponse())
    {
        if (AuthCookie.Count > 0)
        {
            return true;
        }
    }
    return false;
}

然后我按如下方式设置CookieContainer：

client.CookieContainer = AuthCookie;

之后，可以访问Web服务：

static void Main(string[] args)
{
    using (UsrService client = new UsrService())
    {
        if(TryLogin("User 1", "User 1"))
        {
            client.CookieContainer = AuthCookie;
            Console.WriteLine(client.SayHello());
        }
    }
}
