教程:简单的WCF XML-RPC客户端 [英] Tutorial: Simple WCF XML-RPC client

问题描述

更新:我在下面的答案中提供了完整的代码示例.

我已经构建了自己的小型自定义XML-RPC服务器，并且由于我想保持简单，因此无论是在服务器端还是客户端上，我要完成的工作都是创建一个尽可能简单的客户端(最好使用C#) )使用WCF.

I have built my own little custom XML-RPC server, and since I'd like to keep things simple, on both server and client side, what I would like to accomplish is to create a simplest possible client (in C# preferably) using WCF.

让我们说通过XML-RPC公开的服务合同如下:

Let's say that Contract for service exposed via XML-RPC is as follows:

[ServiceContract]
public interface IContract
{
    [OperationContract(Action="Ping")]
    string Ping(); // server returns back string "Pong"

    [OperationContract(Action="Echo")]
    string Echo(string message); // server echoes back whatever message is
}

因此，有两个示例方法，一个不带任何参数，另一个带简单的字符串参数，都返回字符串(仅出于示例目的).服务通过http公开.

So, there are two example methods, one without any arguments, and another with simple string argument, both returning strings (just for sake of example). Service is exposed via http.

Aaand，接下来要做什么? :)

Aaand, what's next? :)

受杜比的回答启发，我查找了有关该主题的更多信息(示例)，并得出以下发现.

Inspired by Doobi's answer, I looked up some more info (examples) on the subject, and came up with the following findings.

创建简单的WCF XML-RPC客户端的步骤:

Steps to create simple WCF XML-RPC client:

1. 从此页面下载WCF的XML-RPC: http://vasters.com/clemensv/PermaLink,guid,679ca50b-c907-4831-81c4-369ef7​​b85839.aspx (下载链接位于页面顶部)
2. 创建一个以 .NET 4.0 Full 框架为目标的空项目(否则System.ServiceModel.Web稍后将不可用)
3. 将存档中的 Microsoft.Samples.XmlRpc 项目添加到您的项目中
4. 添加对Microsoft.Samples.XmlRpc项目的引用
5. 添加对System.ServiceModel和System.ServiceModel.Web的引用

1. Download XML-RPC for WCF from this page: http://vasters.com/clemensv/PermaLink,guid,679ca50b-c907-4831-81c4-369ef7b85839.aspx (download link is at the top of page)
2. Create an empty project which targets .NET 4.0 Full framework (or else System.ServiceModel.Web won't be available later on)
3. Add Microsoft.Samples.XmlRpc project from the archive to your project
4. Add reference to Microsoft.Samples.XmlRpc project
5. Add references to System.ServiceModel and System.ServiceModel.Web

示例代码

using System;
using System.ServiceModel;
using Microsoft.Samples.XmlRpc;

namespace ConsoleApplication1
{


    // describe your service's interface here
    [ServiceContract]
    public interface IServiceContract
    {
        [OperationContract(Action="Hello")]
        string Hello(string name);
    }


    class Program
    {
        static void Main(string[] args)
        {
            ChannelFactory<IServiceContract> cf = new ChannelFactory<IServiceContract>(
                new WebHttpBinding(), "http://www.example.com/xmlrpc");

            cf.Endpoint.Behaviors.Add(new XmlRpcEndpointBehavior());

            IServiceContract client = cf.CreateChannel();

            // you can now call methods from your remote service
            string answer = client.Hello("World");
        }
    }
}

请求/响应消息示例

请求XML

<?xml version="1.0" encoding="utf-8"?>
<methodCall> 
    <methodName>Hello</methodName> 
    <params> 
        <param> 
            <value> 
                <string>World</string> 
            </value> 
        </param> 
    </params> 
</methodCall> 

响应XML

<?xml version="1.0" encoding="utf-8"?>
<methodResponse> 
    <params> 
        <param> 
            <value> 
                <string>Hello, World!</string> 
            </value> 
        </param> 
    </params> 
</methodResponse>
