我使用 blazor 作为前端，api 已完成 JWT 配置。前端可以创建用户帐户并登录API，但现在我的前端httpclient没有设置JWT令牌，所以如果我在Api控制器中设置[授权]，前端将无法访问它。

api程序代码如下

builder.Services.AddIdentity<IdentityUser, IdentityRole>().AddEntityFrameworkStores<DBContext>();//add user model,role model and connect toDbcontext
builder.Services.AddAuthentication(JwtBearerDefaults.AuthenticationScheme)
    .AddJwtBearer(options => {
        options.TokenValidationParameters = new TokenValidationParameters() {
            ValidateIssuer = true,
            ValidIssuer = builder.Configuration["Authentication:Issuer"],
            ValidateAudience = true,
            ValidAudience = builder.Configuration["Authentication:Audience"],
            ValidateLifetime = true,
            IssuerSigningKey = new SymmetricSecurityKey(Encoding.UTF8.GetBytes(builder.Configuration["Authentication:SecretKey"]))
        };
    }); 

控制器代码如下

   [HttpGet("all")]
    [HttpHead]
    //[Authorize(AuthenticationSchemes = "Bearer")]
    [Authorize]
    public async Task<ActionResult<IEnumerable<Quiz>>> GetQuizzesDetailsAsync() {
     
       var quizzes= await _quizzesRepository.GetQuizzesDetailsAsync( );
        var quizDtos=_mapper.Map<IEnumerable<QuizOverviewDto>>(quizzes);
        return Ok(quizDtos);
    }

前端 Blazor 程序代码如下

builder.Services.AddHttpClient<IQuizService, QuizService>(
      client => client.BaseAddress = new Uri("https://localhost:7172"))
    .AddHttpMessageHandler<CustomAuthorizationMessageHandler>();

和“CustomAuthorizationMessageHandler”代码如下。 …
