Question

我在Header中请求gZip响应，如：

request.Headers.Add（HttpRequestHeader.AcceptEncoding，“gzip”）;

在网络回复中我得到 ContentEncoding = gzip

我不知道如何用我的代码解压缩gzip响应，当我用json读取字符串时，我得到 Newtonsoft.Json.JsonReaderException

解决方案是什么？

using (WebResponse response = GetWebResponse(request))
        using (StreamReader reader = new StreamReader(response.GetResponseStream()))
        {
            var result = reader.ReadToEnd();
            return JsonConvert.DeserializeObject<T>(result);
        }

这是我构建请求的方式：

var request = CreateWebRequest(new Uri(uri), type);

        // create request stream from arguments
        if (args != null)
        {
            string requestData = string.Empty;

            requestData = Newtonsoft.Json.JsonConvert.SerializeObject(args, new JsonSerializerSettings { NullValueHandling = NullValueHandling.Ignore });
            var data = Encoding.GetEncoding("UTF-8").GetBytes(requestData);
            request.ContentLength = data.Length;

            using (Stream stream = request.GetRequestStream())
            {
                stream.Write(data, 0, data.Length);                
            }                
        }

 protected WebRequest CreateWebRequest(Uri uri, MethodType type, bool IsUrlEncoded = false)
    {
        WebRequest request = WebRequest.Create(uri);

        (request as HttpWebRequest).Accept = "application/json";
        System.Net.ServicePointManager.Expect100Continue = false;
        if (IsUrlEncoded)
            request.ContentType = "application/x-www-form-urlencoded";
        else
            request.ContentType = "application / json";
            request.Headers.Add("X-Application", AppKeyData.Appkey);
        if (!string.IsNullOrEmpty(AppKeyData.SessionToken))
        {
            request.Headers.Add("X-Authentication", AppKeyData.SessionToken);
        }
        request.Headers.Add(HttpRequestHeader.AcceptEncoding, "gzip");
        request.Method = type.ToString();

        return request;
    }

您必须在请求中设置AutomaticDecompression属性。

request.AutomaticDecompression = DecompressionMethods.GZip | DecompressionMethods.Deflate;

<强>更新

您可以在CreateWebRequest方法中添加以下内容。

(request as HttpWebRequest).AutomaticDecompression = DecompressionMethods.GZip | DecompressionMethods.Deflate;

获取异常Newtonsoft.Json.JsonReaderException
