包含通过HttpClient发起get或post请求的方法,所有调用微信接口的操作都通过此类。话不多说,直接上代码:

  1 public class HttpClientHelper
  2     {
  3         /// <summary>
  4         /// get请求
  5         /// </summary>
  6         /// <param name="url"></param>
  7         /// <returns></returns>
  8         public static string GetResponse(string url)
  9         {
 10             HttpClient httpClient = new HttpClient();
 11             httpClient.DefaultRequestHeaders.Accept.Add(
 12                new MediaTypeWithQualityHeaderValue("application/json"));
 13             HttpResponseMessage response = httpClient.GetAsync(url).Result;
 14 
 15             if (response.IsSuccessStatusCode)
 16             {
 17                 string result = response.Content.ReadAsStringAsync().Result;
 18                 return result;
 19             }
 20             return null;
 21         }
 22 
 23         public static T GetResponse<T>(string url)
 24             where T : class,new()
 25         {

 27             httpClient.DefaultRequestHeaders.Accept.Add(
 28                new MediaTypeWithQualityHeaderValue("application/json"));
 29             HttpResponseMessage response = httpClient.GetAsync(url).Result;
 30 
 31             T result = default(T);
 32

 36                 string s = t.Result;
 37 
 38                 result = JsonConvert.DeserializeObject<T>(s);
 39             }
 40             return result;
 41         }
