我的J2EE应用程序能够从JSP页面接收POST请求,没问题.
但是如果我使用另一个java应用程序发送POST请求,则收到的参数不是UTF-8字符串.
这里有我的代码：
URL url = new URL("http://localhost:8080/ITUNLPWebInterface/SimpleApi");
HttpURLConnection cox = (HttpURLConnection) url.openConnection();
cox.setDoInput(true);
cox.setDoOutput(true);
cox.setRequestMethod("POST");
cox.setRequestProperty("Accept-Charset","UTF-8");
cox.setRequestProperty("Content-Type","application/x-www-form-urlencoded");
cox.setRequestProperty("charset","UTF-8");
DataOutputStream dos = new DataOutputStream(cox.getOutputStream());
String query = "tool=ner&input=şaşaşa";
dos.writeBytes(query);
dos.close();
难道我做错了什么？
感谢您的回复
