[英]C# ASP.NET Core 5.0 - Why the method is not even called, when [Authorization] is used
我有 JWT 令牌和 API。
在 startup.cs - 我有 jwt 授權的配置:
public void ConfigureServices(IServiceCollection services)
{
SetupJWTServices(services);
services.AddControllers();
services.AddSwaggerGen(c =>
{
c.SwaggerDoc("v3", new OpenApiInfo { Title = "MyTitle", Version = "v3" });
c.OperationFilter<AddSwaggerService>();
c.AddSecurityDefinition("Bearer", new OpenApiSecurityScheme
{
Description = "JWT Token authorization",
Name = "Authorization",
In = ParameterLocation.Header,
Type = SecuritySchemeType.ApiKey,
});
}
);
}
private static void SetupJWTServices(IServiceCollection services)
{
string key = "secret Public key Token";
var issuer = "myIssuer";
byte[] publicKey = Convert.FromBase64String(key);
var ecdsa = ECDsa.Create();
ecdsa.ImportSubjectPublicKeyInfo(source: publicKey, bytesRead: out _);
services.AddAuthentication(JwtBearerDefaults.AuthenticationScheme).AddJwtBearer(options =>
{
options.TokenValidationParameters = new TokenValidationParameters
{
ValidateIssuer = true,
ValidateAudience = false,
ValidateIssuerSigningKey = true,
ValidIssuer = issuer,
ValidAudience = issuer,
IssuerSigningKey = new ECDsaSecurityKey(ecdsa),
ValidAlgorithms = new[]
{
@"ES256"
}
};
options.Events = new JwtBearerEvents
{
OnAuthenticationFailed = context =>
{
if (context.Exception.GetType() == typeof(SecurityTokenExpiredException))
{
context.Response.Headers.Add("Token-Expired", "true");
}
return Task.CompletedTask;
}
};
});
}
public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
if (env.IsDevelopment())
{
app.UseDeveloperExceptionPage();
app.UseSwagger();
app.UseSwaggerUI(c => {
c.SwaggerEndpoint("/swagger/v3/swagger.json", "MyAPIService");
});
}
app.UseHttpsRedirection();
app.UseRouting();
app.UseAuthorization();
app.UseAuthentication();
app.UseEndpoints(endpoints =>
{
endpoints.MapControllers();
});
}
然后我在控制器中有方法,我稱之為:
[Authorize]
[HttpGet("CreateNewPassword")]
public IActionResult CreateNewPassword(string Password)
{
if (User.Identity.IsAuthenticated)
{
if (User.Identity is ClaimsIdentity identity)
{
_ = identity.Claims;
}
return Json(new { YourNewHashedPassword = Helpers.GetNewHashedText(Password) });
}
else
{
return Json(new { ErrorMessage = "JWT is invalid!" });
}
}
問題是:
如果我將 [Authorize] 放在方法上方 - 該方法甚至不會執行,調用時(來自 swagger 和來自郵遞員的相同行為)並自動返回 401
如果我刪除 [Authorize] 行為是 - 根據 JWT 令牌是正確的 - 所以如果 JWT 來自 POSTMAN 無效 - 它返回 401 和 ErrorMessage(這沒問題) - 如果 JWT 令牌來自 POSTMAN - 它返回一個新的密碼(這只是我的測試方法)
但! 當我刪除 [Authorize] 並從 swagger 執行調用時 - 總是有消息 401(沒有錯誤消息) - 因為缺少帶有 JWT 令牌的標頭。
問題是:
我如何使用 [Authorize] - 這樣 swagger 和 postman 將正確執行該方法:當 JWT 正確時=它將以常規方式執行當 JWT 無效時=它將返回 401...
認證和授權中間件的順序似乎是錯誤的。 您首先擁有UseAuthorization
。
app.UseRouting();
app.UseAuthorization();
app.UseAuthentication();
app.UseEndpoints(endpoints =>
{
endpoints.MapControllers();
});
試試這個:
app.UseRouting();
app.UseAuthentication();
app.UseAuthorization();
app.UseEndpoints(endpoints =>
{
endpoints.MapControllers();
});
