android - Android 通过 Json 将希伯来字母传递给基于服务器的 Spring MVC 出现乱码

Question

我正在构建一个 Android 应用程序，我需要通过 Json 将希伯来语（UTF-8？）字母传递给服务器，而这些字母显示为乱码。试图在网上寻找信息，但没有运气。怎么可能做到这一点？

in the JSONParser.java class:

public JSONObject makeHttpRequest(String url, String method,
        List<NameValuePair> params) {
    Log.d("params in json",String.valueOf(params));
    // Making HTTP request
    try {

        // check for request method
        if(method == "POST"){
            // request method is POST
            // defaultHttpClient
            DefaultHttpClient httpClient = new DefaultHttpClient();
            HttpPost httpPost = new HttpPost(url);
            httpPost.setEntity(new UrlEncodedFormEntity(params, "utf-8"));

            HttpResponse httpResponse = httpClient.execute(httpPost);
            HttpEntity httpEntity = httpResponse.getEntity();
            is = httpEntity.getContent();

        }else if(method == "GET"){
            // request method is GET
            DefaultHttpClient httpClient = new DefaultHttpClient();
            String paramString = URLEncodedUtils.format(params, "utf-8");
            url += "?" + paramString;
            HttpGet httpGet = new HttpGet(url);

            HttpResponse httpResponse = httpClient.execute(httpGet);
            HttpEntity httpEntity = httpResponse.getEntity();
            is = httpEntity.getContent();
        }           

    } catch (UnsupportedEncodingException e) {
        e.printStackTrace();
    } catch (ClientProtocolException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }

    try {
        BufferedReader reader = new BufferedReader(new InputStreamReader(
                is, "iso-8859-1"), 8);
        StringBuilder sb = new StringBuilder();
        String line = null;
        while ((line = reader.readLine()) != null) {
            sb.append(line + "\n");
        }
        is.close();
        json = sb.toString();
    } catch (Exception e) {
        Log.e("Buffer Error", "Error converting result " + e.toString());
    }

    // try parse the string to a JSON object
    try {
        jObj = new JSONObject(json);
    } catch (JSONException e) {
        Log.e("JSON Parser", "Error parsing data " + e.toString());
    }

    // return JSON String
    return jObj;

}

I had the same problem, found the solution, hope it can still help. in the line:

httpPost.setEntity(new UrlEncodedFormEntity(params, "utf-8"));

I didn't have the utf-8 defined. I used post method, if you use get method then the line is:

String paramString = URLEncodedUtils.format(params, "utf-8");
