做阀门的英文网站怎么写/手机打开国外网站app

我现在已经花了一半星期天,我现在需要帮助：

我想使用Java HttpURLConnection将包含特殊字符UTF-8编码的字符串发送到服务器.字符的正确编码失败.

例：

strToSend: ä ù €

strUrlEncoded: %C3%A4+%C3%B9+%E2%82%AC

strReceived:ä ù â¬

我的代码：

urlConnection = (HttpURLConnection) new URL("http://localhost:8080/NetworkingServer/ServerServlet").openConnection();

urlConnection.setUseCaches(false);

urlConnection.setDoOutput(true); // Triggers POST.

urlConnection.setRequestProperty("accept-charset", "UTF-8");

urlConnection.setRequestProperty("content-type", "application/x-www-form-urlencoded");

String strToSend = "ä ù €";

System.out.println("strToSend: " + strToSend);

String strUrlEncoded = URLEncoder.encode(strToSend, "UTF-8");

System.out.println("strUrlEncoded: " + strUrlEncoded);

OutputStreamWriter writer = new OutputStreamWriter(urlConnection.getOutputStream(), "UTF-8");

writer.write(String.format("content=%s", strUrlEncoded));

writer.close();

有任何想法吗？

解决方法:

您需要在Content-Type标头中设置编码.

将其设置为“application / x-www-form-urlencoded; charset = utf-8”.目前你只设置了accept-charset – 这告诉服务器要发回什么.
