解决http://wthrcdn.etouch.cn/weather_mini?city=接口获取天气的返回字符串是乱码

最近在做一个类似天气预报的demo,数据是从http://wthrcdn.etouch.cn/weather_mini?city=获取，但是解析出来的字符串是乱码，通常更换编码类型就可以了，但是并不见效。所以最后才发现问题所在，这个接口的数据传给客户端的时候把数据压缩了，所以当我们在客户端获取到数据后要给他解压缩gzip即可，问题就解决了，现在把代码贴出来。

// 获取天气预报public void getWeatherByHttp(String city) {String url = Constants.GETWEATHER;ArrayList<NameValuePair> params = new ArrayList<NameValuePair>();params.add(new BasicNameValuePair("city", city));String param = URLEncodedUtils.format(params, "utf-8");HttpGet httpGet = new HttpGet(url + param);HttpClient httpClient = new DefaultHttpClient();try {HttpResponse httpResponse = httpClient.execute(httpGet);String result = getJsonStringFromGZIP(httpResponse);// 获取到解压缩之后的字符串Log.i("result", result);JSONObject obj = new JSONObject(result);if (obj != null && obj.getString("desc").equals("OK")) {String str = obj.getString("data");WeatherModel model = new Gson().fromJson(str,WeatherModel.class);handler.sendMessage(handler.obtainMessage(GETWEATHERDATA, model));} else {handler.sendMessage(handler.obtainMessage(GETWEATHERDATA,obj.getString("desc")));}} catch (Exception e) {e.printStackTrace();}}private String getJsonStringFromGZIP(HttpResponse response) {String jsonString = null;try {InputStream is = response.getEntity().getContent();BufferedInputStream bis = new BufferedInputStream(is);bis.mark(2);// 取前两个字节byte[] header = new byte[2];int result = bis.read(header);// reset输入流到开始位置bis.reset();// 判断是否是GZIP格式int headerData = getShort(header);if (result != -1 && headerData == 0x1f8b) {is = new GZIPInputStream(bis);} else {is = bis;}InputStreamReader reader = new InputStreamReader(is, "utf-8");char[] data = new char[100];int readSize;StringBuffer sb = new StringBuffer();while ((readSize = reader.read(data)) > 0) {sb.append(data, 0, readSize);}jsonString = sb.toString();bis.close();reader.close();} catch (Exception e) {Log.e("HttpTask", e.toString(), e);}return jsonString;}private int getShort(byte[] data) {return (int) ((data[0] << 8) | data[1] & 0xFF);}
