.net 调用java rest ful api 实例

注意post的参数组合

HttpWebRequest request = WebRequest.Create(url) as HttpWebRequest;
request.Method = "POST";
request.KeepAlive = true;
request.AllowAutoRedirect = false;
request.ContentType = "application/x-www-form-urlencoded";
byte[] postdatabtyes = Encoding.UTF8.GetBytes("param={"imsi":"","session":"hwJPCFmgNRtyOED91iTwpteCY"}");
request.ContentLength = postdatabtyes.Length;
Stream requeststream = request.GetRequestStream();
requeststream.Write(postdatabtyes, , postdatabtyes.Length);
requeststream.Close();
string resp;
try{
using (HttpWebResponse response = request.GetResponse() as HttpWebResponse)
{
StreamReader sr = new StreamReader(response.GetResponseStream(), Encoding.UTF8);
resp = sr.ReadToEnd();
}
}

另外一种:

、以Post方式获取

  using System.Web;

  Uri address = new Uri("http://api.search.yahoo.com/ContentAnalysisService/V1/termExtraction");

  // Create the web request
  HttpWebRequest request = WebRequest.Create(address) as HttpWebRequest;   // Set type to POST
  request.Method = "POST";
  request.ContentType = "application/x-www-form-urlencoded";   // Create the data we want to send
  string appId = "YahooDemo";
  string context = "Italian sculptors and painters of the renaissance"
  + "favored the Virgin Mary for inspiration";
  string query = "madonna";   StringBuilder data = new StringBuilder();
  data.Append("appid=" + HttpUtility.UrlEncode(appId));
  data.Append("&context=" + HttpUtility.UrlEncode(context));
  data.Append("&query=" + HttpUtility.UrlEncode(query));   // Create a byte array of the data we want to send
  byte[] byteData = UTF8Encoding.UTF8.GetBytes(data.ToString());   // Set the content length in the request headers
  request.ContentLength = byteData.Length;   // Write data
  using (Stream postStream = request.GetRequestStream())
  {
  postStream.Write(byteData, , byteData.Length);
  }   // Get response
  using (HttpWebResponse response = request.GetResponse() as HttpWebResponse)
  {
  // Get the response stream
  StreamReader reader = new StreamReader(response.GetResponseStream());   // Console application output
  Console.WriteLine(reader.ReadToEnd());
  }
  三、HTTP 验证请求   有些朋友在调用Restful Api时,可能要提供用户名和密码进行Http身份验证,这里我们可以通过为请求增加一个 NetworkCredentials 实例来完成.   // Create the web request
  HttpWebRequest request
  = WebRequest.Create("https://api.del.icio.us/v1/posts/recent") as HttpWebRequest;   // Add authentication to request
  request.Credentials = new NetworkCredential("username", "password");   // Get response
  using (HttpWebResponse response = request.GetResponse() as HttpWebResponse)
  {
  // Get the response stream
  StreamReader reader = new StreamReader(response.GetResponseStream());   // Console application output
  Console.WriteLine(reader.ReadToEnd());
  }
