HTTP GET请求

Hi,
Try this REST web API example.
HTTP GET Requests

static string HttpGet(string url) {
  HttpWebRequest req = WebRequest.Create(url)
                       as HttpWebRequest;
  string result = null;
  using (HttpWebResponse resp = req.GetResponse()
                                as HttpWebResponse)
  {
    StreamReader reader =
        new StreamReader(resp.GetResponseStream());
    result = reader.ReadToEnd();
  }
  return result;
}

HTTP POST请求

HTTP POST Requests

<pre lang="c#">

静态字符串HttpPost（字符串url，

string [] paramName，string [] paramVal）

{

HttpWebRequest req = WebRequest.Create（new Uri（url））

as HttpWebRequest;

req.Method =POST;

req.ContentType =application / x-www-form-urlencoded;



StringBuilder paramz = new StringBuilder（）;

for（int i = 0; i< paramName.Length; i ++）{

paramz.Append（paramName [i]）;

paramz .Append（=）;

paramz.Append（HttpUtility.UrlEncode（paramVal [i]））;

paramz.Append（&）;
}



//将参数编码为表格数据：

byte [] formData =

UTF8Encoding.UTF8.GetBytes（paramz.ToString（））;

req.ContentLength = formData.Length;



/ /发送请求：

使用（Stream post = req.GetRequestStream（））

{

post.Write（formData，0，formData 。长度）;

}





string result = null;

using（HttpWebResponse resp = req.GetResponse（）

as HttpWebResponse）

{

StreamReader reader =

new StreamReader（resp。 GetResponseStream（））;

result = reader.ReadToEnd（）;

}



返回结果;

}

static string HttpPost(string url,
string[] paramName, string[] paramVal)
{
HttpWebRequest req = WebRequest.Create(new Uri(url))
as HttpWebRequest;
req.Method = "POST";
req.ContentType = "application/x-www-form-urlencoded";

StringBuilder paramz = new StringBuilder();
for (int i = 0; i < paramName.Length; i++) {
paramz.Append(paramName[i]);
paramz.Append("=");
paramz.Append(HttpUtility.UrlEncode(paramVal[i]));
paramz.Append("&");
}

// Encode the parameters as form data:
byte[] formData =
UTF8Encoding.UTF8.GetBytes(paramz.ToString());
req.ContentLength = formData.Length;

// Send the request:
using (Stream post = req.GetRequestStream())
{
post.Write(formData, 0, formData.Length);
}


string result = null;
using (HttpWebResponse resp = req.GetResponse()
as HttpWebResponse)
{
StreamReader reader =
new StreamReader(resp.GetResponseStream());
result = reader.ReadToEnd();
}

return result;
}
