如何通过C中的伪REST服务发出get请求#

在 WCF REST Starter Kit ,用于实现调用在任何平台中实现的服务的.NET REST客户端。

Here's a video 它描述了如何使用客户端部件。

示例代码片段:

HttpClient c = new HttpClient("http://twitter.com/statuses");
c.TransportSettings.Credentials = 
    new NetworkCredentials(username, password);
// make a GET request on the resource.
HttpResponseMessage resp = c.Get("public_timeline.xml");
// There are also Methods on HttpClient for put, delete, head, etc
resp.EnsureResponseIsSuccessful(); // throw if not success
// read resp.Content as XElement
resp.Content.ReadAsXElement(); 

简单的 System.Net.Webclient 功能上类似于 python 的 urllib .

这个 C# 示例(从上面的引用中略微编辑)显示了如何“触发一个GET请求”:

using System;
using System.Net;
using System.IO;
using System.Web;

public class Test
{
    public static String GetRequest (string theService, string[] params)
    {
        WebClient client = new WebClient ();

        // Add a user agent header in case the 
        // requested URI contains a query.

        client.Headers.Add ("user-agent", "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.2; .NET CLR 1.0.3705;)");

        string req = theService + "?";
        foreach(string p in params)
            req += HttpUtility.UrlEncode(p) + "&";
        Stream data = client.OpenRead ( req.Substring(0, req.Length-1)
        StreamReader reader = new StreamReader (data);
        return = reader.ReadToEnd ();
    }
}

要分析结果,请使用System.xml类或更好的类- System.Xml.Linq 类。一个直接的可能性是 XDocument.Load(TextReader) 方法-您可以使用 WebClient 流返回者 OpenRead() 直接。
