這個主要用于WebApi和MVC進行交互橋梁的一種方法

public class HttpClientHelper { public HttpClientHelper(string baseAddr){this.BaseAddr = baseAddr;}public string BaseAddr { get; set; } public string Get(string Url){HttpClient client = new HttpClient();//設置 API的 基地址client.BaseAddress=newUri(BaseAddr);//設置 默認請求頭ACCEPTclient.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));//發送GET請求HttpResponseMessage msg = client.GetAsync(Url).Result;//判斷結果是否成功if (msg.IsSuccessStatusCode){//返回響應結果return msg.Content.ReadAsStringAsync().Result;}//返回空字符串，表示響應錯誤return "";}public string Delete(string Url){HttpClient client = new HttpClient();//設置 API的 基地址client.BaseAddress = new Uri(BaseAddr);//設置 默認請求頭ACCEPTclient.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));//發送GET請求HttpResponseMessage msg = client.DeleteAsync(Url).Result;//判斷結果是否成功if (msg.IsSuccessStatusCode){//返回響應結果return msg.Content.ReadAsStringAsync().Result;}//返回空字符串，表示響應錯誤return "";} public string Post(string Url,string JsonData){HttpClient client = new HttpClient();//設置 API的 基地址client.BaseAddress = new Uri(BaseAddr);//設置 默認請求頭ACCEPTclient.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));//設置消息體HttpContent content = new StringContent(JsonData);content.Headers.ContentType = new MediaTypeHeaderValue("application/json");//發送Post請求HttpResponseMessage msg = client.PostAsync(Url,content).Result;//判斷結果是否成功if (msg.IsSuccessStatusCode){ //返回響應結果return msg.Content.ReadAsStringAsync().Result;}//返回空字符串，表示響應錯誤return "";} public string Put(string Url, string JsonData){HttpClient client = new HttpClient();//設置 API的 基地址client.BaseAddress = new Uri(BaseAddr);//設置 默認請求頭ACCEPTclient.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));//設置消息體HttpContent content = new StringContent(JsonData);content.Headers.ContentType = new MediaTypeHeaderValue("application/json");//發送Post請求HttpResponseMessage msg = client.PutAsync(Url, content).Result;//判斷結果是否成功if (msg.IsSuccessStatusCode){ //返回響應結果return msg.Content.ReadAsStringAsync().Result;}//返回空字符串，表示響應錯誤return "";} public T Request<T>(string type, string url, object data = null){string json = JsonConvert.SerializeObject(data);string result = "";switch (type){ case "Get": result = Get(url); break; case "Post": result = Post(url, json); break; case "Put": result = Put(url, json); break; case "Delete": result = Delete(url); break;}return JsonConvert.DeserializeObject<T>(result);} }
