制作一个简易的RestClient类

public class RestClient
{
private HttpWebRequest CreateHttpRequest(string url, string method)
{
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
this.SetProxy(request);
request.Headers.Set("Cache-Control", "No-Cache");
request.Method = method;
request.ContentType = "application/json";
return request;
}

public virtual T Post<T>(string url, object requestContact) where T : class
{
T local;
HttpWebRequest request = this.CreateHttpRequest(url, "Post");
if (requestContact != null)
{
using (Stream stream = request.GetRequestStream())
{
new DataContractJsonSerializer(requestContact.GetType()).WriteObject(stream, requestContact);
}
}
using (WebResponse response = request.GetResponse())
{
using (Stream stream2 = response.GetResponseStream())
{
local = new DataContractJsonSerializer(typeof(T)).ReadObject(stream2) as T;
}
}
return local;
}

public T Get<T>(string url, object requestContact) where T : class
{
T local;
HttpWebRequest request = this.CreateHttpRequest(url, "GET");
if (requestContact != null)
{
using (Stream stream = request.GetRequestStream())
{
new DataContractJsonSerializer(requestContact.GetType()).WriteObject(stream, requestContact);
}
}
using (WebResponse response = request.GetResponse())
{
using (Stream stream2 = response.GetResponseStream())
{
local = new DataContractJsonSerializer(typeof(T)).ReadObject(stream2) as T;
}
}
return local;
}

private void SetProxy(HttpWebRequest request)
{
WebProxy proxy2 = new WebProxy
{
Credentials = CredentialCache.DefaultCredentials
};
WebProxy proxy = proxy2;
request.Proxy = proxy;
}
}
