本文介绍如何使用Java通过HTTP POST方法发送带有中文参数的请求，并确保正确编码这些参数以避免乱码问题。文章详细展示了设置请求头、处理异常及连接管理的过程。

  URL httpurl;
  String str = "username=中国";
  String url = "http://127.0.0.1:8080/login.do";
  try {
   str = URLEncoder.encode(str, "utf-8");
   // 如有中文一定要加上，在接收方用相应字符转码即可
  } catch (UnsupportedEncodingException e1) {
   // TODO Auto-generated catch block
   e1.printStackTrace();
  }
  HttpURLConnection httpurlconnection = null;
  try {
   httpurl = new URL(url + str);
   httpurlconnection = (HttpURLConnection) httpurl.openConnection();
   httpurlconnection.setDoOutput(true);
   httpurlconnection.setRequestMethod("POST");
   httpurlconnection.setRequestProperty("Content-type", "text/html");
   httpurlconnection.setRequestProperty("Accept-Charset", "utf-8");
   httpurlconnection.setRequestProperty("contentType", "utf-8");
   if (httpurlconnection.getResponseCode() == httpurlconnection.HTTP_OK) {
   }
