为越南语Android设置UTF-8

Question

我需要从Android设备向服务器发送字符串（越南语），如下所示：

HttpClient httpclient = new DefaultHttpClient();
    HttpPost httppost = new HttpPost(Constants.URL.UPDATE_CURRENT_STATUS);
    try {
        // Add your data
        List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
        nameValuePairs.add(new BasicNameValuePair("location", "Thạch thất Hanoi "));
        httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs,
                HTTP.UTF_8));
        // Execute HTTP Post Request
        HttpResponse response = httpclient.execute(httppost);
        int respnseCode = response.getStatusLine().getStatusCode();
        if (respnseCode == 200) {
            HttpEntity entity = response.getEntity();
            return EntityUtils.toString(entity);
        }
    } catch (ClientProtocolException e) {
    } catch (IOException e) {
    }

但当服务器得到字符串时，它不像

Thạch thất Hanoi 

它变成

Thạch Thất Hanoi 

我在服务器端的代码：

    @RequestMapping(value = "/UpdateCurrentStatus", method = RequestMethod.POST, produces = { "application/json" })
    @ResponseBody
    public MessageDTO updateCurrentStatus(
                @RequestParam Map<String, String> requestParams) throws TNException {
      String location = requestParams.get("location");
      System.out.println(location);
    MessageDTO result = driverBO.updateCurrentStatus(location);
              return result;
}

我该如何解决这个问题？非常感谢。

您是否将android httpclient Content-Type标头设置为application/json；charset=utf-8而不是"application/json"？

我认为您的问题是您发送的内容实体location以UTF-8正确编码，但服务器无法确认UTF-8。在"内容类型"标题中对其进行澄清。

您可以使用伟大的http监控工具Fiddler诊断http内容及其标头。

按如下方式放松UrlEncodedFormEntity。如前所述，将标头设置为application/json; charset=utf-8。把它设置得静止是件好事。

        JSONObject jsonParam = new JSONObject();
        jsonParam.put("location", "Thạch thất Hanoi ");
        StringEntity entity = new StringEntity(jsonParam.toString(), "UTF-8");
        httppost.setEntity(entity);
