使用HttpClient操作ASP.NET Web API 2.1增删改查

使用NuGet包安装Microsoft ASP.NET Web API 2.1 Client Libraries,

调用方式代码如下：

 　　　　　　HttpClient client = new HttpClient();
            client.BaseAddress = new Uri("http://localhost:2471/");//基地址
            client.DefaultRequestHeaders.Accept.Add(
                new MediaTypeWithQualityHeaderValue("application/json"));
            HttpResponseMessage response = client.GetAsync("api/values").Result;
            if (response.IsSuccessStatusCode)
            {
                var products = response.Content.ReadAsAsync<IEnumerable<ProductInfo>>().Result;
            }
            else
            {
                Console.WriteLine("{0} ({1})", (int)response.StatusCode, response.ReasonPhrase);
            }

          
            
            //HTTP Post请求
            ProductInfo pro = new ProductInfo();
            pro.dateTime1 = DateTime.Now;
            pro.Int = 1;
             response = client.PutAsJsonAsync<ProductInfo>("api/Values", pro).Result;
            if (response.IsSuccessStatusCode)
            {
                
            }
            else
            {
                Console.WriteLine("{0} ({1})", (int)response.StatusCode, response.ReasonPhrase);
            }

           response =  client.DeleteAsync("api/values/5").Result;
           if (response.IsSuccessStatusCode)
           {

           }
           else
           {
               Console.WriteLine("{0} ({1})", (int)response.StatusCode, response.ReasonPhrase);
           }

values控制器代码如下：

public IEnumerable<ProductInfo> GetList()
        {
            //string s = this.Request.Headers.GetValues("YXLCookie").FirstOrDefault();

            ProductInfo p = new ProductInfo();
            p.Int = 432;
            p.string1 = "432432";
            p.dateTime2 = DateTime.Now;


            ProductItem pi = new ProductItem() { Int = 1, string1 = "432432" };
            p.productItem = pi;

            ProductInfo p2 = new ProductInfo();
            p2.Int = 432;
            p2.string1 = "432432";
            p2.dateTime2 = DateTime.Now;


            ProductItem pi2 = new ProductItem() { Int = 1, string1 = "432432", dateTime1 = DateTime.Now };
            p2.productItem = pi2;

            List<ProductInfo> list = new List<ProductInfo>();
            list.Add(p);
            list.Add(p2);

            return list;
        }

      

        // POST api/values
        public void PostProduct([FromBody]ProductInfo pro)
        {

        }
        // DELETE api/values/5
        public void Delete(int id)
        {
        }

使用JsonConvert要安装Json.NET，使用NuGet安装Json.NET如果我们新增json格式的数据，需要将json格式转换为object对象，代码如下：

HttpClient client = httpClient;
            client.BaseAddress = new Uri("https://api.weixin.qq.com");
            client.DefaultRequestHeaders.Accept.Add(
                new MediaTypeWithQualityHeaderValue("application/json"));
            
           
            object s1 = JsonConvert.DeserializeObject<object>(@"{
                 'button':[
                 {    
                      'type':'click',
                      'name':'协运跟踪',
                      'key':'V1001_TODAY_MUSIC'
                  },
                  {
                       'type':'click',
                       'name':'金牌航线',
                       'key':'V1001_TODAY_SINGER'
                  },
                  {
                       'name':'菜单测试',
                       'sub_button':[
                       {    
                           'type':'view',
                           'name':'运价',
                           'url':'http://weixin.51xieyun.com/price/index'
                        },
                        {
                           'type':'view',
                           'name':'首页',
                           'url':'http://weixin.51xieyun.com'
                        },
                        {
                           'type':'click',
                           'name':'赞一下我们',
                           'key':'V1001_GOOD'
                        }]
                   }]
             }
            ");
            HttpResponseMessage response = client.PostAsJsonAsync<object>("cgi-bin/menu/create?access_token=dPm9S5I6bMKp3QHhcxxqyJhuaNH4h20lJaIeNi-gXVbkpQCsUdyvOLbfQCPmDFWMIS0LowOXSVfu1iD47VC9nolu29-rRJ0oWUhIX0WRDYKPOIZtf4onsSvFePdt1iX9jba5rmhR769OG7cye--V4g", s1).Result;
            if (response.IsSuccessStatusCode)
            {
                var products = response.Content.ReadAsAsync<object>().Result;
            }
            else
            {
                Console.WriteLine("{0} ({1})", (int)response.StatusCode, response.ReasonPhrase);
            }
