Asp.Net Web Api JWT 身份授权始终获得 401

Question

我正在使用 Asp.Net Core 5，Asp.Net Identity with EFcore。我遵循了许多视频教程的部分内容、在 SO 上发布的建议和 this 非常有用的文章，使我的项目达到至少获得 401 的程度。我现在的问题是我不明白为什么我会收到 401。我已经在 jwt.io 上用我的秘密验证了我的令牌，一切都告诉我它应该工作，但事实并非如此。我完全不知所措。废话不多说，言归正传。

我的创业公司Class。注意：在 OnMessageReceived 事件中 context.Token 为空，直到我使用授权 header.

            app.UseEndpoints(endpoints =>
            {
                endpoints.MapControllers();

我的授权控制器。有三个端点。两个用于测试我拥有的角色，一个用于测试任何有效的 jwt。都是return一个401.

// imports

namespace auto_highlighter_iam.Controllers
{
    [ApiController]
    [Route("/api-v1/[controller]")]
    public class AuthorizationController : ControllerBase
    {
        [HttpGet("[action]")]
        [Authorize(Roles = "SUPERADMIN")]
        public IActionResult TestSuperAdmin()
        {
            return Ok();
        }

        [HttpGet("[action]")]
        [Authorize(Roles = "DEFAULT")]
        public IActionResult TestDefault()
        {
            return Ok();
        }

        [HttpGet("[action]")]
        [Authorize]
        public IActionResult TestAny()
        {
            return Ok();
        }
    }
}

我正在测试的 JWT（假装令牌没有过期，我一直在确保它有效）

Answer 1

你需要把你的中间件：

app.UseAuthentication();

在你的app.UseAuthorization();

之前

像这样：

app.UseAuthentication();
app.UseAuthorization();

更新：

并且您需要将您的请求更改为（删除 Bearer）：

curl --location --request GET 'http://localhost:5000/api-v1/Authorization/TestAny' \
--header 'Authorization: eyJhbGciOiJIUzUxMiIsInR5cCI6IkpXVCJ9.eyJWSUVXIjoiRmFsc2UiLCJFRElUIjoiRmFsc2UiLCJERUxFVEUiOiJGYWxzZSIsIkNSRUFURSI6IkZhbHNlIiwicm9sZXMiOiJERUZBVUxUIiwibmJmIjoxNjExMTIwMDkzLCJleHAiOjE2MTExMjM2OTMsImlzcyI6ImF1dG8taGlnaGxpZ2h0ZXItaWFtIiwiYXVkIjoiYXV0by1oaWdobGlnaHRlci1mcm9udC1lbmQifQ.zOsNADvKGx1FYkzKLX4K53Y185dHFiM408aAjinQUQrVWQ_spXClozOAvp2glgiQkM0IwkDneB4Q_JCpQfet1g'
