[英]Web Service call error
我已经从提供的WSDL文件创建了WCF服务参考。 在C#中,我创建了具有基本绑定的代理客户端实例,并调用了所需的方法:
public static bool main()
{
Debugger.Launch();
var binding = new BasicHttpsBinding();
binding.Security.Mode = BasicHttpsSecurityMode.Transport;
binding.TextEncoding = System.Text.Encoding.UTF8;
var remoteAddress = new System.ServiceModel.EndpointAddress("https://tester.mysite.de:8443/webservice/OrderNumber");
using (var orderNumberClient = new orderNumberClient(new System.ServiceModel.BasicHttpBinding(BasicHttpSecurityMode.Transport), remoteAddress))
{
string IDSystem = "123";
string IDOSystem = "abc";
//set timeout
orderNumberClient.Endpoint.Binding.SendTimeout = new TimeSpan(0, 0, 0, 10000);
orderNumberClient.ClientCredentials.UserName.UserName = "test";
orderNumberClient.ClientCredentials.UserName.Password = "test";
//call web service method
string productResponse = orderNumberClient.getNewOrderNumber(IDSystem, "01", IDOSystem); ;
MessageBox.Show(productResponse);
}
return true;
}
不幸的是,当我调用“ getNewOrderNumber”方法时,我收到了一个无用的错误:
System.Reflection.TargetInvocationException:Ein Aufrufziel发生异常。 ---> System.ServiceModel.FaultException:Web服务处理异常
服务器堆栈跟踪:
bei System.ServiceModel.Channels.ServiceChannel.HandleReply(ProxyOperationRuntime操作,ProxyRpc&rpc)
bei System.ServiceModel.Channels.ServiceChannel.Call(字符串操作,布尔型单向,ProxyOperationRuntime操作,Object [] ins,Object [] out,TimeSpan超时)
bei System.ServiceModel.Channels.ServiceChannelProxy.InvokeService(IMethodCallMessage methodCall,ProxyOperationRuntime操作)
...
这不是Web服务方面的错误,因为在SOAPUI中可以正常工作,我是否可能在绑定中缺少某些内容?
希望对网络服务有更多了解的人可以阐明根本原因。
事实证明,我没有随电话一起发送“ Authorization”标头。 为了克服该问题,在进行实际的Web服务方法调用之前,我使用了OperationContextScope
类将所需的HttpRequestMessageProperty
添加到代理实例内部通道:
using (OperationContextScope scope = new OperationContextScope(orderNumberClient.InnerChannel))
{
var httpRequestProperty = new HttpRequestMessageProperty();
httpRequestProperty.Headers[System.Net.HttpRequestHeader.Authorization] = "Basic " +
Convert.ToBase64String(Encoding.ASCII.GetBytes(orderNumberClient.ClientCredentials.UserName.UserName + ":" +
orderNumberClient.ClientCredentials.UserName.Password));
OperationContext.Current.OutgoingMessageProperties[HttpRequestMessageProperty.Name] = httpRequestProperty;
string Response = orderNumberClient.getNewOrderNumber(IDSystem, "01", IDOSystem);
}
