Java进行Http连接时出现invalid http response

[weixin_38055863]

下面是我的代码，不带参数发起Http连接时不会出现invalid Http Response，一带参数就会出现错误。求高手为我解答一下 import java.net.URL; import java.net.URLEncoder; import java.net.HttpURLConnection; import java.io.*; public class Http {     public static final String POST_URL="http://kirasms.sinaapp.com?";     public static void connect() throws IOException{     StringBuffer get_url=new StringBuffer(POST_URL);     get_url.append(URLEncoder.encode("Message=HelloJava","UTF-8"));     URL url=new URL(get_url.toString());     HttpURLConnection connect=(HttpURLConnection)url.openConnection();     connect.connect();     BufferedReader reader = new BufferedReader(new InputStreamReader(connect.getInputStream()));     String line;     while((line=reader.readLine())!=null)      System.out.println(line);     reader.close();     connect.disconnect();   }   public static void main(String[] args){      try{     connect(); }catch(IOException e){     e.printStackTrace(); }   } } 服务器端的处理代码是： <?php echo $_GET['Message']; ?>
