使用IHttpClientFactory设置默认请求头

Question

我正在开发一个ASP.NET Core应用程序，在该应用程序中，当用户到达某个页面时，我希望为每个请求设置一个授权头。我试着使用来自DefaultRequestHeaders.Authorization类的HttpClient。然而，它只是没有设置标题。这是我的密码：

启动

public void ConfigureServices(IServiceCollection services)
{
    services.AddHttpClient();
    //Some more code
}

控制器

public class MyController: Controller
{
    private readonly System.Net.Http.IHttpClientFactory _clientFactory;

    public MyController(System.Net.Http.IHttpClientFactory clientFactory)
    {
         _clientFactory = clientFactory;
    }

    public IActionResult MethodWhichIWantToSetTheToken()
    {
        var client = _clientFactory.CreateClient();
        client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue(JwtBearerDefaults.AuthenticationScheme, "veryBigTokenHere");
         
       string abc = Request.Headers["Authorization"]; //Yeah, it's null!
       return View();
    }

Answer 1

而不是

  client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue(JwtBearerDefaults.AuthenticationScheme, "veryBigTokenHere");

使用

 client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", "veryBigTokenHere");
