[英]Cors policy error when using Authorize Attribute
I am getting a cors policy error whenever I use Authorize attribute on my user controller.I am using Angular 8 as my front-end framework and asp .net core 3.0.0 as my backend.It is working fine if I remove the authorize attribute from the controller.每当我在用户控制器上使用 Authorize 属性时,我都会收到 cors 策略错误。我使用 Angular 8 作为我的前端框架,使用 asp .net core 3.0.0 作为我的后端。如果我删除授权属性,它工作正常从控制器。
.
. Below is my startup.cs file.
下面是我的startup.cs文件。
using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Threading.Tasks;
using AutoMapper;
using DatingApp.API.Data;
using DatingApp.API.Helpers;
using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Diagnostics;
using Microsoft.AspNetCore.Hosting;
using Microsoft.AspNetCore.Http;
using Microsoft.AspNetCore.HttpsPolicy;
using Microsoft.AspNetCore.Mvc;
using Microsoft.EntityFrameworkCore;
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Hosting;
using Microsoft.Extensions.Logging;
using Microsoft.Extensions.Options;
namespace DatingApp.API {
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.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_3_0);
services.AddDbContext<DataContext>(x => x.UseSqlite(Configuration.GetConnectionString("DefaultConnection")));
services.AddCors(options =>
{
options.AddPolicy("CorsPolicy",
builder => builder.AllowAnyOrigin()
.AllowAnyMethod()
.AllowAnyHeader());
});
services.AddAutoMapper(typeof(DatingRepository).Assembly);
services.AddScoped<IAuthRepository, AuthRepository>();
services.AddScoped<IDatingRepository, DatingRepository>();
}
// 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();
}
else
{
app.UseExceptionHandler(builder =>
{
builder.Run(async context =>
{
context.Response.StatusCode = (int)HttpStatusCode.InternalServerError;
var error = context.Features.Get<IExceptionHandlerFeature>();
if (error != null)
{
context.Response.AddApplicationError(error.Error.Message);
await context.Response.WriteAsync(error.Error.Message);
}
});
});
// The default HSTS value is 30 days. You may want to change this for production scenarios, see https://aka.ms/aspnetcore-hsts.
// app.UseHsts();
}
app.UseHttpsRedirection();
app.UseRouting();
app.UseAuthorization();
app.UseCors("CorsPolicy");
app.UseEndpoints(endpoints =>
{
endpoints.MapControllers().RequireCors("CorsPolicy");
});
}
}
}
Firstly I need to add app.UseAuthentication();
首先我需要添加
app.UseAuthentication();
for adding the authentication as a middleware in my startup.cs file and then I also need to configure the same in my services.用于在我的 startup.cs 文件中添加身份验证作为中间件,然后我还需要在我的服务中配置相同的内容。 Here is modification in startup.cs file
这是在startup.cs文件中的修改
