11       {
12           using (HttpClient client = new HttpClient())
13           {
14               HttpRequestMessage request = new HttpRequestMessage(method, url);
15               if (method == HttpMethod.Post && !string.IsNullOrEmpty(postData))
16               {
17                   request.Content = new StringContent(postData);
18               }
19 
20               HttpResponseMessage response = await client.SendAsync(request);
21               if (response.IsSuccessStatusCode)
22               {
23                   return await response.Content.ReadAsStringAsync();
24               }
25               else
26               {
27                   Console.WriteLine($"Request failed: {response.StatusCode}");
28                   return null;
29               }
30           }
31       }

33       /// <summary>
34       /// Make an HTTP request.

37       /// <param name="method">The request method.</param>
38       /// <param name="requestBody">The request body parameters.</param>
39       /// <returns></returns>
40       public static string HttpRequest(string baseUrl, Method method, RestRequest requestBody)
41       {
42           try
43           {
44               var client = new RestClient(baseUrl);
45 
46               requestBody.Method = method;
47               var response = client.Execute(requestBody);
48               if (response.StatusCode == HttpStatusCode.OK)
49               {
50                   return response.Content;
51               }
52 
53               throw new Exception("HTTP request result error: " + response.ErrorMessage);
54           }
55           catch (Exception ex)
56           {
57               throw new Exception("HTTP request failed: " + ex.Message);
58           }
59       }
60   }

请注意，当 response.StatusCode 状态不是ok时，我会抛出异常。如果不符合业务，请自行修改。
