1、get请求类型接口调用

 public JObject GetDate(string url)
        {
            url = RequestIP + url;//比如【http://192.168.xx.xx:1234】
            using (var httpClient = new HttpClient())
            {
                httpClient.DefaultRequestHeaders.Add("Accept", "application/json");//设置请求头
                //get
                var url1 = new Uri(url);
                // response
                var response = httpClient.GetAsync(url1).Result;
                var data = response.Content.ReadAsStringAsync().Result;

                JObject obj = (JObject)JsonConvert.DeserializeObject(data);
                return obj;
            }
        }

处理接口返回的jobject数据

//数据结构
 {\"message\": \"请求成功\",\"nid\": \"321\",\"nid\":{\"mid\": \"123456\",\"nid\": \"321\",\"details\": [" +
                "{\"mid\": \"1\",\"name\": \"111\" }," +
                "{\"mid\": \"5\", \"name\": \"555\" } ]" +
                "}"+
                "}";
//获取返回消息
JObject obj=GetDate（url）
obj["message"].ToString() == "请求成功"
//获取数据详情，
 JArray jar = (JArray)JsonConvert.DeserializeObject(obj["details"].ToString());
 string mid1=jar[0]["mid"].ToString()
  string mid2=jar[1]["mid"].ToString()

2、 post请求类型接口调用

      //content为body中的参数
     // content数据格式:
             content = "{\"identity_card_id\":\"" + identity.Content + "\"" +
                 ",\"flight_no\":\"" + flight.Content.ToString() + "\",\"plane_ticket_no\":\"3790C40WILUZWU\",\"boarding_date\":\"" + this.boarding_date.Content.ToString() +
                 "\",\"seat_number\":\"" + seat_number.Content.ToString() + "\",\"aircraft_cabin\":\"" + aircraft_cabin.Content.ToString() + "\"" +
                 ",\"checkcollecting\":\""+ userimage + "\",\"SecurityStates\":\"0\",\"process_node\":\"" + Constant.PROCESS_NODE_SIC_CODE + "\"}";
        public string PostDate(string url, string content)
        {
            url = RequestIP + url;//比如【http://192.168.xx.xx:1234】
            //post
            HttpWebRequest httpWeb = (HttpWebRequest)WebRequest.Create(url);
            httpWeb.Headers.Add("Accept", "application/json");//添加消息头
            httpWeb.Timeout = 20000;
            httpWeb.Method = "POST";
            httpWeb.ContentType = "application/json; charset=utf-8";
            byte[] bytePara = Encoding.UTF8.GetBytes(content);
            using (Stream reqStream = httpWeb.GetRequestStream())
            {
                //提交数据
                reqStream.Write(bytePara, 0, bytePara.Length);
            }
            //获取服务器返回值
            HttpWebResponse httpWebResponse = (HttpWebResponse)httpWeb.GetResponse();
            Stream stream = httpWebResponse.GetResponseStream();
            StreamReader streamReader = new StreamReader(stream, Encoding.GetEncoding("utf-8"));
            //获得返回值
            string result = streamReader.ReadToEnd();
            stream.Close();
            return result;
        }

处理接口返回值

var jObject1 = JObject.Parse(PostDate(url, content));

if(jObject1["message"].ToString() == "请求成功")
