【第七篇】Volley之处理Gzip数据

一般对于API请求需带上GZip压缩，因为API返回数据大都是JSon串之类字符串，GZip压缩后内容大小大幅降低.

public class GZipRequest extends StringRequest {
    public GZipRequest(int paramInt, String paramString,
            Response.Listener<String> paramListener,
            Response.ErrorListener paramErrorListener) {
        super(paramInt, paramString, paramListener, paramErrorListener);
    }

    public GZipRequest(String paramString,
            Response.Listener<String> paramListener,
            Response.ErrorListener paramErrorListener) {
        super(paramString, paramListener, paramErrorListener);
    }

    protected Response<String> parseNetworkResponse(
            NetworkResponse paramNetworkResponse) {
        String str1 = "";

            try {
                GZIPInputStream gzipInputStream = new GZIPInputStream(
                        new ByteArrayInputStream(paramNetworkResponse.data));
                InputStreamReader inputStreamReader = new InputStreamReader(
                        gzipInputStream);
                BufferedReader bufferedReader = new BufferedReader(
                        inputStreamReader);
                while (true) {
                    String str2 = bufferedReader.readLine();
                    if (str2 == null)
                        break;
                    str1 = str1 + str2;
                }
                inputStreamReader.close();
                bufferedReader.close();
                gzipInputStream.close();
                return Response.success(str1,
                        HttpHeaderParser.parseCacheHeaders(paramNetworkResponse),
                        false);
            } catch (IOException e) {
                e.printStackTrace();
            }
             return Response.error(new ParseError());
    }
}
