Question

我有一个 API，我为身份验证实现了 jwt，这是我的身份验证：

         [Route("api/[controller]")]
            [ApiController]
            public class AuthController : ControllerBase
            {

                [HttpPost, Route("login")]
                public IActionResult Login([FromBody]LoginModel user)
                {
                   if (user == null)
                    {
                        return BadRequest("Invalid client request");
                    }


                    if (user.UserName == "test" && user.Password == "1234")
                    {

                        var secretKey = new SymmetricSecurityKey(Encoding.UTF8.GetBytes("sretKey@345"));
                        var signinCredentials = new SigningCredentials(secretKey, SecurityAlgorithms.HmacSha256);

                        var tokeOptions = new JwtSecurityToken(

                            issuer: "https://localhost:44361",
                            audience: "https://localhost:44378",
                            claims: new List<Claim>(),
                            expires: DateTime.Now.AddMinutes(25),
                            signingCredentials: signinCredentials
                        );

在邮递员这里是错误

在我的控制器中，我添加了授权属性，我在没有授权属性的情况下测试了我的控制器并且它可以工作，问题是为什么它没有授权我使用凭据

这是我的启动

             public class Startup
            {
                public Startup(IConfiguration configuration)
                {
                    Configuration = configuration;
                }

                public IConfiguration Configuration { get; }

                // This method gets called by the runtime. Use this method to add services to the container.
                public void ConfigureServices(IServiceCollection services)
                {
                    services.AddAuthentication(opt => {
                        opt.DefaultAuthenticateScheme = JwtBearerDefaults.AuthenticationScheme;
                        opt.DefaultChallengeScheme = JwtBearerDefaults.AuthenticationScheme;
                    })
                    .AddJwtBearer(options =>
                    {
                        options.TokenValidationParameters = new TokenValidationParameters
                        {
                            ValidateIssuer = true,
                            ValidateAudience = true,
                            ValidateLifetime = true,
                            ValidateIssuerSigningKey = true,

                            ValidIssuer = "https://localhost:44361",
                            ValidAudience = "https://localhost:44378",
                            IssuerSigningKey = new SymmetricSecurityKey(Encoding.UTF8.GetBytes("sretKey@345"))
                        };
                    });

                    services.AddCors(options =>
                    {
                        options.AddPolicy("EnableCORS", builder =>
                        {
                            builder.WithOrigins("http://localhost:44378")
                            .AllowAnyHeader()
                            .AllowAnyMethod();
                        });
                    });




                    services.AddDbContext<DbContextClass>(options =>
                    options.UseNpgsql(Configuration.GetConnectionString("DefaultConnection")));


               
                    services.AddControllers();

                }

                // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
                public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
                {
                    if (env.IsDevelopment())
                    {
                        app.UseDeveloperExceptionPage();
                    }

                    app.UseHttpsRedirection();

                    app.UseRouting();

                    app.UseAuthorization();

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

在您的登录操作中添加 AllowAnonymous

  [AllowAnonymous]
 [HttpPost("login")]
 public IActionResult Login([FromBody]LoginModel user)
{
.... your code
var token = new JwtSecurityTokenHandler().WriteToken(tokeOptions);
return Ok(token);
}

在此之后，您必须配置启动以使用此令牌。而且您还必须将此令牌添加到 Postman 以进行动作测试。 Postman 有一个特殊的菜单 Autorization。打开它，选择令牌选项并将您的令牌粘贴到该字段中。如果需要，不要登录并传递输入操作参数

并尝试像这样添加 app.UseAuthentication() ：

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