C# 处理gzip格式的json

看代码中对response的处理即可，

public class GetParam
{
   
    public GetParam(string key, string value)
    {
   
        this.key = key;
        this.value = value;
    }

    public string key {
    get; set; }
    public string value {
    get; set; }
}


public static string RestfulGet(List<GetParam> getParams,string url)
{
   
    StringBuilder urlBulder = new StringBuilder();
    urlBulder.Append(url);
    GetParam item;
    if (getParams.Count>0)
    {
   
        item = getParams[0];
        urlBulder.Append(item.key);
        urlBulder.Append("=");
        urlBulder.Append(item.value);
    }
    for (int i = 1; i < getParams.Count; i++)
    {
   
        item = getParams[i];
        urlBulder.Append("&");
        urlBulder.Append(item.key);
        urlBulder.Append("=");
        urlBulder.Append(item.value);
    }
    HttpWebRequest request = WebRequest.Create(urlBulder.ToString()) as HttpWebRequest;
    request.Method = "GET";
    string json = string.Empty; 
    using (HttpWebResponse response = request.GetResponse() as HttpWebResponse)
    {
   
        Stream responseStream = responseStream = response.GetResponseStream();
        if (response.ContentEncoding.ToLower().Contains("gzip"))
            responseStream = new GZipStream(responseStream, CompressionMode.Decompress);
        else if (response.ContentEncoding.ToLower().Contains("deflate"))
            responseStream = new DeflateStream(responseStream, CompressionMode.Decompress);

        StreamReader reader = new StreamReader(responseStream, Encoding.UTF8);
        json = reader.ReadToEnd();
    }
    return json;
}
