RestSharp发送请求得到Json数据

NUGET安装：RestSharp

code:

public string Post(string url, string content)
{
string contentType = "application/json"; //Content-Type
try
{
var client = new RestClient(url);
var request = new RestRequest(Method.POST);
request.Timeout = 10000;
request.AddParameter(contentType, content, ParameterType.RequestBody);

IRestResponse response = client.Execute(request);
return response.Content; //返回的结果
}
catch (Exception ex)
{
return "连接服务器出错： " + ex.Message;
}
}

public class RestClientManager
    {
        public JObject Post(string baseUrl, string url, JObject sendData)
        {
            return Post(baseUrl, url, sendData, string.Empty);
        }

        public JObject Post(string baseUrl, string url, JObject sendData, string token)
        {
            RestClient client = new RestClient(baseUrl);
            var request = new RestRequest(url, Method.POST);
            var contenType = "application/json";
            request.AddHeader("Accept", contenType);
            if (!string.IsNullOrWhiteSpace(token))
            {
                request.AddHeader("token", token);
            }
            if (sendData == null)
            {
                sendData = new JObject();
            }
            request.AddParameter(contenType, sendData, ParameterType.RequestBody);
            var response = client.Execute(request);
            if (string.IsNullOrWhiteSpace(response.Content))
            {
                return null;
            }
            return JObject.Parse(response.Content);
        }

        public JObject Get(string baseUrl, string url, JObject sendData)
        {
            return Get(baseUrl, url, sendData, string.Empty);
        }

        public JObject Get(string baseUrl, string url, JObject sendData, string token)
        {
            string parames = string.Empty;
            if (sendData != null)
            {
                StringBuilder datas = new StringBuilder();
                foreach (var item in sendData)
                {
                    datas.AppendFormat("{0}={1}", item.Key, item.Value);
                }
                parames = string.Format("?{0}", string.Join("&", datas));
            }
            var client = new RestClient(string.Format("{0}{1}{2}", baseUrl, url, parames));
            var request = new RestRequest(Method.GET);
            var response = client.Execute(request);
            return JObject.Parse(response.Content);
        }
    }

使用：

　　　　　　　string baseUrl = "https://api.weixin.qq.com";
            string urlToken = @"/sns/oauth2/access_token";
            JObject paras = new JObject
            {
                ["appid"] = "",
                ["secret"] = "",
                ["code"] = "",
                ["grant_type"] = "authorization_code"
            };
            JObject objToken = new RestClientManager().Get(baseUrl, urlToken, paras);
　　　　　　　if (objToken["errcode"] == null)
            {
                string access_token = objToken["access_token"].Value<string>();
                string openid = objToken["openid"].Value<string>();
　　　　　　　}
