RestSharp组件Get请求带body的时候返回数据丢失问题

postman的复制代码默认就是RestSharp。方便也好用，但是使用get请求并且带Body的时候要注意，返回的数据竟然会有丢失

解决办法：

string RequestByGet(string index, string action, object paramter)
{
    var api = $"{ElasticsearchUrl}/{index}/{action}";
    HttpWebRequest request = (HttpWebRequest)WebRequest.Create(api);
    request.Proxy = null;
    request.KeepAlive = false;
    request.Method = "GET";
    request.ContentType = "application/json; charset=UTF-8";
    request.AutomaticDecompression = DecompressionMethods.GZip;
    string body = InitBody("order", paramter);

    var type = request.GetType();
    var currentMethod = type.GetProperty("CurrentMethod", BindingFlags.NonPublic | BindingFlags.Instance).GetValue(request);
    var methodType = currentMethod.GetType();
    methodType.GetField("ContentBodyNotAllowed", BindingFlags.NonPublic | BindingFlags.Instance).SetValue(currentMethod, false);

    using (var streamWriter = new StreamWriter(request.GetRequestStream()))
    {
        streamWriter.Write(body);
    }

    HttpWebResponse response = (HttpWebResponse)request.GetResponse();
    Stream myResponseStream = response.GetResponseStream();
    StreamReader myStreamReader = new StreamReader(myResponseStream, Encoding.UTF8);
    string retString = myStreamReader.ReadToEnd();

    myStreamReader.Close();
    myResponseStream.Close();

    if (response != null)
    {
        response.Close();
    }
    if (request != null)
    {
        request.Abort();
    }
    return retString;
}
