使用WebHelper调用Asp.net WebAPI

1.WebHelper

 using System;
 using System.Collections.Generic;
 using System.Collections.Specialized;
 using System.Linq;
 using System.Net;
 using System.Net.Http;
 using System.Text;
 using System.Threading.Tasks;

 namespace CommonFoundation.Common
 {
     public class WebHelper
     {
         public WebHelper(string _url)
         {
             url = _url;
         }
         private string url;
         /// <summary>
         /// 接口调用地址
         /// </summary>
         public string Url
         {
             get { return url; }
             set { url = value; }
         }
         /// <summary>
         /// get请求
         /// </summary>
         /// <returns></returns>
         public async Task<string> get()
         {
             var result = string.Empty;
             using (var client = new HttpClient())
             {
                 result = await client.GetStringAsync(url);
             }
             return result;
         }

         /// <summary>
         /// post请求
         /// </summary>
         /// <param name="value">参数值</param>
         /// <returns></returns>
         public async Task<string> post(string value)
         {
             //var handler = new HttpClientHandler() { AutomaticDecompression = DecompressionMethods.GZip };
             var result = string.Empty;
             using (var client = new HttpClient())
             {
                 var values = new List<KeyValuePair<string, string>>();
                 values.Add(new KeyValuePair<string, string>("", value));
                 var content = new FormUrlEncodedContent(values);
                 var response = await client.PostAsync(url, content);
                 var responseString = await response.Content.ReadAsStringAsync();
                 result = responseString;
             }
             return result;
         }

         public string post1()
         {
             string result = "";
             using (var client = new WebClient())
             {
                 var values = new NameValueCollection();
                 values[""] = "shunfeng";

                 var response = client.UploadValues("http://localhost:15954/api/test", values);

                 var responseString = Encoding.Default.GetString(response);
             }
             return result;
         }
     }
 }

2.调用

 private static async void test()
         {
             var url = "https://www.bjcytxkj.com/api/express";
             WebHelper webHelper = new WebHelper(url);
             var dic = new Dictionary<string, string>();
             dic["ShipperName"] = "SF";
             dic["ShipperCode"] = "";
             string str = JsonConvert.SerializeObject(dic);
             var result1 = await webHelper.get();
             var result = await webHelper.post(str);
             result = result.Replace("\\", "");
             Console.WriteLine(result);
         }
