在用HttpWebRequest对象时,一般我们都没有开启gzip压缩,如果服务端返回的数据比较大,这是我们需要开启gzip压缩,怎么开启呢?
1.给HttpWebRequest对象,添加如下Header:
request.Headers.Add("Accept-Encoding", "gzip");2.对接收到的流进行解码:
PRivate string GetResponseBody(HttpWebResponse response){ string responseBody = string.Empty; if (response.ContentEncoding.ToLower().Contains("gzip")) { using (GZipStream stream = new GZipStream(response.GetResponseStream(), CompressionMode.Decompress)) { using (StreamReaderreader = new StreamReader(stream)) { responseBody = reader.ReadToEnd(); } } } else if (response.ContentEncoding.ToLower().Contains("deflate")) { using (DeflateStream stream = new DeflateStream( response.GetResponseStream(), CompressionMode.Decompress)) { using (StreamReader reader = new StreamReader(stream, Encoding.UTF8)) { responseBody = reader.ReadToEnd(); } } } else { using (Stream stream = response.GetResponseStream()) { using (StreamReader reader = new StreamReader(stream, Encoding.UTF8)) { responseBody = reader.ReadToEnd(); } } } return responseBody;}
