最近在專案中又遇到一個小問題，通過HttpURLConnection來傳遞漢字時，服務端獲取漢字引數時都為亂碼，以下分別為在servlet或action中獲取URL中的漢字解決辦法：

1.   以下程式碼為 通過HttpURLConnection連線來傳遞引數，其中，對待漢字的操作需要先進行編碼的操作，之後在服務端進行解碼操作即可。

	public static void main(String[] args) throws UnsupportedEncodingException {
		 
//		String url = "http://61.154.14.46:8080/exter.shtml?serviceType=1011";
		String name = java.net.URLEncoder.encode("行子愛上大叔的","UTF-8");
		String url = "http://localhost:8081/exter.shtml?serviceType=1023&guid=11&mobile=13696900475&content=123" + name;
//		String url = "http://localhost:8080/webtest/servlet/URLTest?name=這個是測試用的" + name;
//		String url = "http://localhost:8081/exter.shtml?serviceType=1022&menuId=4481&mobile=15806092760&text_data=linlinlin&imgName=testa.jpg";
//		getReturnData1(url);
		sendPost(url,null);
	}
