Question

我有一个可用的XML POST请求，直到我更改字段以包含拉丁文UTF-8字符，例如“Î”。我从该服务收到400 Bad Response。

这两项请求都适用于Google Chrome扩展程序Postman。

我认为这与Java编码字符或读取数据流的方式有关。下面是我的代码，包括相关的库。怎么解决这个？谢谢！

public class CardCallbacks extends ValutecWSCallbackHandler  {
    private void sendInfoToMaropost(GiftCard please) throws IOException {

        URL serverUrl = new URL(TARGET_URL + API_KEY);
        URLConnection urlConnection = serverUrl.openConnection();
        HttpURLConnection hcon = (HttpURLConnection)urlConnection;
        System.out.println(dont.getBarcode());
        try {


            hcon.setReadTimeout(10000);
            hcon.setConnectTimeout(15000);
            hcon.setRequestMethod("POST");
            hcon.setRequestProperty("Content-Type", "application/xml");
            hcon.setRequestProperty("Accept", "application/xml");
            hcon.setDoInput(true);
            hcon.setDoOutput(true);

            String body = 

                "<?xml version=\"1.0\" encoding=\"UTF-8\"?>" +
                "<record>" + 
                        "  <orderlineid>fakeorderid</orderlineid>" +

                           //the request that doesn't work
                "</record>";    

            OutputStream output = new BufferedOutputStream(hcon.getOutputStream());

            output.write(body.getBytes());
            output.flush();

            int responseCode = hcon.getResponseCode();
            System.out.println(responseCode);
            if(responseCode == 200) {

            }
            BufferedReader in = new BufferedReader(
                    new InputStreamReader(hcon.getInputStream()));

            String inputLine;
            StringBuffer response = new StringBuffer();

            while((inputLine = in.readLine()) != null) {
                response.append(inputLine);
            }



            System.out.println(response);

            in.close();

        }
        finally {
            hcon.disconnect();
        }
    }

编辑：我找到了解决方案。这有助于：Unicode字符这是所需的编辑：

output.write(body.getBytes("UTF-8"));

该类的默认编码是“ISO 8859-1”。我没弄明白如何将“响应”格式化为UTF-8，以便仍然返回错误的字符。

拉丁字符破坏了Java
