• RestSharp使用

var url = "https://i.cnblogs.com/posts";
            var client = new RestClient(url);
            var request = new RestRequest("ControllerName/ActionName", Method.POST);
            request.AddParameter("name","linda");
            request.AddParameter("id","123");
            var response = client.Execute(request);
            Console.WriteLine(response.Content);
