public static String sendGet(String url,String param)

    while ((line = in.readLine())!= null)
    {
     result += line;
    }
    in.close();   
   }catch(Exception e){
    System.out.println("没有结果！"+e);
   }
   return result;
}

public static String sendPost(String url,String param)
{
   String result="";
   try{
