[英]Send UTF-8 chars via HttpURLConnection failing
I have spent half Sunday on this now I need help: 我现在已经花了一半星期天,我现在需要帮助:
I want to send a String including special chars UTF-8 encoded to a server using Java HttpURLConnection. 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。 The correct encoding of the chars fails. 字符的正确编码失败。
Example: 例:
strToSend: ä ù € strUrlEncoded: %C3%A4+%C3%B9+%E2%82%AC strReceived:ä ù â¬
My code: 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();
Any ideas? 有任何想法吗?
You need to set the encoding in your Content-Type
header. 您需要在Content-Type
标头中设置编码。
Set it to " application/x-www-form-urlencoded; charset=utf-8
". 将其设置为“ application/x-www-form-urlencoded; charset=utf-8
”。 Currently you only set the accept-charset
- this tells the server what to send back. 目前你只设置了accept-charset
- 这告诉服务器要发回什么。
