How to pass user credentials to web service?

我想使用以下代码使用Web服务:

WebService.GenRelClient client = new WebService.GenRelClient();
client.ClientCredentials.UserName.UserName = @"UserName";
client.ClientCredentials.UserName.Password = @"Password";
var response = client.returnString("test");

我的配置如下所示:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <startup>
    <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" />
  </startup>
  <system.serviceModel>
    <bindings>
      <basicHttpBinding>
        <binding name="GenRelClientPortBinding">
        <security mode="TransportCredentialOnly">
          <transport clientCredentialType="Basic" />
        </security>
        </binding>
      </basicHttpBinding>
    </bindings>
    <client>
      <endpoint
          address="http://ws.domain.com/GenRel/GenRel"
          binding="basicHttpBinding"
          bindingConfiguration="GenRelClientPortBinding"
          contract="WebService.GenRelClientPort"
          name="GenRelClientPort" />
    </client>
  </system.serviceModel>
</configuration>

该请求被发送到Web服务，并以不正确的消息发送回响应，该消息表明它需要基本身份验证，因为该请求可能是没有凭据发送的，所以我不知道错误在哪里。

为了能够调用Web服务，您将需要在SOAP header 中添加安全信息。

单击here以阅读MSDN文章，其中解释了基本原理。

查看下面的代码示例，看看它是否可以解决您的问题:

 var client = new WCClient();
 using (OperationContextScope scope = new OperationContextScope(client.InnerChannel))
 {
     var httpRequestProperty = new HttpRequestMessageProperty();
     httpRequestProperty.Headers[System.Net.HttpRequestHeader.Authorization] = "Basic " +
                  Convert.ToBase64String(Encoding.ASCII.GetBytes(client.ClientCredentials.UserName.UserName + ":" +
                  client.ClientCredentials.UserName.Password));
     OperationContext.Current.OutgoingMessageProperties[HttpRequestMessageProperty.Name] = httpRequestProperty;

     client.DoSomething();
 }
