编码/解码HttpPost UTF-8 Java

Question

我在尝试将utf8格式的发布数据从客户端发送到我的服务器时遇到了麻烦.

我已经阅读了很多关于这个主题但我找不到解决方案.我确信我遗漏了一些基本的东西.

这是我发布帖子请求的客户端代码

public static PostResponse post(String url, String data) {
        PostResponse response = new PostResponse();
        try {
            // 1. create HttpClient
            HttpClient httpclient = new DefaultHttpClient();

            // 2. make POST request to the given URL
            HttpPost httpPost = new HttpPost(url);
            httpPost.setHeader("Content-Type", "text/plain; charset=UTF-8");

            // 3. set string to StringEntity
            StringEntity se = new StringEntity(data);

            // 4. set httpPost Entity
            httpPost.setEntity(se);

            // 5. Execute POST request to the given URL
            HttpResponse httpResponse = httpclient.execute(httpPost);

        } catch (IOException e) {

        }
        return response;

    }

这是我服务器端的代码,用于接收utf8中的文本(波兰字符没有出现,我得到"？"而不是.)

protected void doPost(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
try {
            BufferedReader reader;
            reader = req.getReader();
            Gson gson = new Gson();
            msg = gson.fromJson(reader, MsgChat.class); //String in the client was json
        } catch (IOException e) {

        }
}

我只写了相关的代码.

我将不胜感激任何帮助.谢谢.

Answer 1

我有同样的问题.您应该使用此代码:

httpPost.setEntity(new StringEntity(json, "UTF-8"));

希望这可以帮到你.

Answer 2

据我所知你应该使用new StringEntity(data, ContentType.APPLICATION_JSON). 默认情况下iso-8859-1，setHeader据我所知，这不是设置编码的正确方法。
