请求 https://api.github.com/users (api) returns System.Net.HttpStatusCode.Forbidden IsSuccessStatusCode = false

Question

我试图向 https://api.github.com/users 发出 api 请求，但我收到了这个被禁止的响应。由于它不需要身份验证，我不知道为什么会返回 403。

{StatusCode: 403, Version: 1.0, Content: System.Net.Http.StreamContent, 
Headers:

RequestMessage = {Method: GET, RequestUri: 'https://api.github.com/users', 
Version: 1.1, Content: <null>, Headers:
{
   Accept: application/json
}}

ReasonPhrase = "Forbidden"
IsSuccessStatusCode = false

以下是我的代码。

namespace ConsumingWebAapiRESTinMVC.Controllers
{
public class HomeController : Controller
    {
    //Hosted web API REST Service base url  
    string Baseurl = "https://api.github.com/users";
    public async Task<ActionResult> Index()
    {
        List<Employee> EmpInfo = new List<Employee>();

        using (var client = new HttpClient())
        {
            //Passing service base url  
            client.BaseAddress = new Uri(Baseurl);

            client.DefaultRequestHeaders.Clear();
            //Define request data format  
            client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));

            //Sending request to find web api REST service resource GetAllEmployees using HttpClient  
            HttpResponseMessage Res = await client.GetAsync(Baseurl);

            //Checking the response is successful or not which is sent using HttpClient  
            if (Res.IsSuccessStatusCode)
            {
                //Storing the response details recieved from web api   
                var EmpResponse = Res.Content.ReadAsStringAsync().Result;

                //Deserializing the response recieved from web api and storing into the Employee list  
                EmpInfo = JsonConvert.DeserializeObject<List<Employee>>(EmpResponse);

            }
            //returning the employee list to view  
            return View(EmpInfo);
        }
    }
}

}

如果您检查实际的响应文本 Res.Content.ReadAsStringAsync().Result 那么您会看到以下错误消息：

Request forbidden by administrative rules. Please make sure your request has a User-Agent header (http://developer.github.com/v3/#user-agent-required). Check https://developer.github.com for other possible causes.

您需要添加一个User-Agent header。

client.DefaultRequestHeaders.Add("User-Agent", "C# App");

但更普遍的是，您需要改进日志记录，以便了解无法正常工作的真正原因。
