Question

我有一个json wcf。给出了地址。 wsdl中的代码具有以下内容：

<wsdl:binding name="BasicHttpBinding_iBOER" type="tns:iBOER">
 <soap:binding transport="http://schemas.xmlsoap.org/soap/http" /> 
 - <wsdl:operation name="PhoneCall">
 <soap:operation soapAction="http://tempuri.org/iBOER/PhoneCall" style="document" /> 
 - <wsdl:input>
 <soap:body use="literal" /> 
 </wsdl:input>
- <wsdl:output>
 <soap:body use="literal" /> 
 </wsdl:output>
 </wsdl:operation>

- <wsdl:service name="BOER">
- <wsdl:port name="BasicHttpBinding_iBOER" binding="tns:BasicHttpBinding_iBOER">
      <soap:address location="http://wsvc01/BOER/BOER.svc" /> 
  </wsdl:port>
  </wsdl:service>

如何在C＃中使用它？只是可以吗？

class Test
{
   static void Main()
   {
       iBOERClient client = new iBOERClient();

      // Use the 'client' variable to call operations on the service.

      // Always close the client.
      client.Close();
   }
}

我是否需要将URL放在客户端？该服务有两个DataContract和许多DataMember。我对此并不坚强。

感谢。

您实际上没有JSON WCF服务。您有一个服务，可能有也可能没有可以接收/发送JSON数据的端点。您要显示的WSDL列出了一个使用基于SOAP的绑定（wsdl:port）的端点（BasicHttpBinding）。可以“谈话”JSON的端点使用WebHttpBinding定义，并且应用了一个特定行为（WebHttpBehavior） - 并且do not show up in the WSDL。

因此，您无法使用由添加服务引用或svcutil.exe等工具生成的客户端来使用它。如果您在客户端代码中拥有相同的合同，则可以使用ChannelFactory<T>或WebChannelFactory<T>等类创建代理以与服务进行通信，或者您可以手动处理请求并将其发送到使用通用HTTP客户端的服务。

下面的示例代码显示了如何使用WebChannelFactory<T>和“普通”HTTP客户端（WebClient）来使用JSON端点。

            Address = new Address

        });
        Console.WriteLine(proxy.FindPerson("John Doe").Age);
        Console.WriteLine();

        Console.WriteLine("Accessing via \"normal\" HTTP client");
        string jsonInput = "{'Name':'Jane Roe','Age':30,'Address':{'Street':'1 Wall St','City':'Springfield','Zip':'12346'}}".Replace('\'', '\"');
        WebClient c = new WebClient();
        c.Headers[HttpRequestHeader.ContentType] = "application/json";
        c.UploadString(baseAddress + "/RegisterPerson", jsonInput);

        c = new WebClient();
        Console.WriteLine(c.DownloadString(baseAddress + "/FindPerson?name=Jane Roe"));
        Console.WriteLine();

        Console.Write("Press ENTER to close the host");
        Console.ReadLine();
        host.Close();
    }
}
