轉向的處理

  // 填入各個表單域的值

  // 將表單的值放入postMethod中
  postMethod.setRequestBody(data);
  // 執行postMethod
  int statusCode = httpClient.executeMethod(postMethod);
  System.out.println(" status code:" + statusCode);
  // HttpClient對于要求接受后繼服務的請求，象POST和PUT等不能自動處理轉發
 

 

if(statusCode == HttpStatus.SC_OK)
  {
   StringBuffer contentBuffer = new StringBuffer();
   InputStream in = postMethod.getResponseBodyAsStream();
            BufferedReader reader = new BufferedReader(new InputStreamReader(in,postMethod.getResponseCharSet()));
            String inputLine = null;
            while((inputLine = reader.readLine()) != null)
            {
             contentBuffer.append(inputLine);
             System.out.println("input line:"+ inputLine);
             contentBuffer.append("/n");
            }
            in.close();

  }
  else if (statusCode == HttpStatus.SC_MOVED_PERMANENTLY || statusCode == HttpStatus.SC_MOVED_TEMPORARILY) 
  {
      // 從頭中取出轉向的地址
      Header locationHeader = postMethod.getResponseHeader("location");
      String location = null;
      if (locationHeader != null) 
      {
       location = locationHeader.getValue();
       System.out.println("The page was redirected to:" + location);
      } 
      else

 }

從文件讀取
