C#에서 http 프로토콜을 이용한 인터페이스.

protected void HttpCall()
{
    String callUrl = "http://localhost:8080/test/call";
    String[] data = new String[1];
    data[0] = "nikemodel";         // id
    data[1] = "password";          // pw
    
    String postData = String.Format("id=&pw=", data[0], data[1]); 
    HttpWebRequest httpWebRequest = (HttpWebRequest) WebRequest.Create(callUrl);

    //인코딩 UTF-8
    byte[] sendData = UTF8Encoding.UTF8.GetBytes(postData);
    httpWebRequest.ContentType = "application/x-www-form-urlencoded; charset=UTF-8";
    httpWebRequest.Method = "POST";
    httpWebRequest.ContentLength = sendData.Length;

    Stream requestStream = httpWebRequest.GetRequestStream();
    requestStream.Write(sendData, 0, sendData.Length);
    requestStream.Close();

    HttpWebResponse httpWebResponse = (HttpWebResponse) httpWebRequest.GetResponse();
    StreamReader streamReader = new StreamReader(httpWebResponse.GetResponseStream(), Encoding.GetEncoding("UTF-8"));    
    String response = streamReader.ReadToEnd();

    streamReader.Close();
    httpWebResponse.Close();
 
    console.Write("response : " + response);
