Android HttpPost數據中文亂碼的解決方案

在項目中，以HttpPost方式向服務器上提交數據時，服務器上中文竟然顯示亂碼，針對該種情況證明解決呢？其實，這樣的問題，在架構的時候，就應該考慮到，如果牽扯到各個不同的平臺應用，盡量統一使用UTF8編碼，可以少很多麻煩。當然在post數據的時候，可以指定編碼，請參閱下面的函數：

   public Map<String, Object> CreateNote(int albumId, String title,
            String remark) {
        String noteId = "";
        Map<String, Object> map = new HashMap<String, Object>();
        try {
            HttpParams parms = new BasicHttpParams();
            parms.setParameter("charset", HTTP.UTF_8);
                    HttpConnectionParams.setConnectionTimeout(parms, 8  1000);
                    HttpConnectionParams.setSoTimeout(parms, 8  1000);
            HttpClient httpclient = new DefaultHttpClient(parms);
            HttpPost httppost = new HttpPost(ConfigHelper.CreateUri);
            httppost.addHeader("Authorization", mToken);
            httppost.addHeader("Content-Type", "application/json");

            httppost.addHeader("charset", HTTP.UTF_8);


        JSONObject obj = new JSONObject();
        obj.put("title", title);
        obj.put("categoryId", mCategoryId);
        obj.put("sourceUrl", GetSourceUri());

        JSONArray arr = new JSONArray();

        arr.put(DateFormat.format("yyyyMM",Calendar.getInstance(Locale.CHINA)));      
        obj.put("tags", arr);
        obj.put("content", remark);   
        httppost.setEntity(new StringEntity(obj.toString(), HTTP.UTF_8));
        HttpResponse response;
        response = httpclient.execute(httppost);
        int code = response.getStatusLine().getStatusCode();
        if (code == ConstanDefine.ErrorCode.SuccOfHttpStatusCode) {
            String rev = EntityUtils.toString(response.getEntity());
            obj = new JSONObject(rev);
            noteId = obj.getString("id");
            map.put("return_code", "0");
            map.put("content", rev);          
        }
    } catch (Exception e) {
        if (map.containsKey("return_code")) {
            map.remove("return_code");
        }
        map.put("return_code", "1");        
    }
    return map;
