Question

当我手动调用wcf服务时，我应该在url中输入什么：

HttpWebRequest httpWebRequest = WebRequest.Create(url)as HttpWebRequest;

应该是我的svc文件的URL

http://localhost/service/LMTService.svc

或wsdl

http://localhost/service/LMTService.svc?wsdl

或网址服务行动？

http://localhost/service/LMTService.svc/soap/GetSerializedSoapData

这取决于端点的绑定。如果使用SOAP绑定（即basicHttpBinding，wsHttpBinding等），请求URI应该是端点地址（而不是服务地址）。此外，在某些SOAP版本（例如，basicHttpBinding中使用的SOAP11）中，您需要将操作指定为HTTP标头。如果您正在使用webHttpBinding（具有webHttp行为），则地址是端点的地址，以及要调用的操作的UriTemplate（默认情况下只是方法名称）。 / p>

以下代码显示基于HttpWebRequest的请求发送到两个端点，一个使用BasicHttpBinding，一个使用WebHttpBinding。
