[英]ASP.NET core Cors policy
I'm having problem setting up Cors policy in my ASP.NET core project.我在我的 ASP.NET 核心项目中设置 Cors 策略时遇到问题。
public void ConfigureServices(IServiceCollection services)
{
services.AddCors(options =>
{
options.AddPolicy("AllowAll",
builder =>
{
builder
.AllowAnyOrigin()
.AllowAnyMethod()
.AllowAnyHeader()
.AllowCredentials();
});
});
services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_1);
services.AddMemoryCache();
}
I've tried adding app.UseCors("AllowAll");
我试过添加
app.UseCors("AllowAll");
in Configure(IApplicationBuilder app, IHostingEnvironment env)
, tried [EnableCors("AllowAll")]
before controller declaration:在
Configure(IApplicationBuilder app, IHostingEnvironment env)
中,在 controller 声明之前尝试了[EnableCors("AllowAll")]
:
[Route("api/[controller]")]
[ApiController]
[EnableCors("AllowAll")]
public class TestController : ControllerBase
and before method declaration:和方法声明之前:
[HttpPost]
[EnableCors("AllowAll")]
public JsonResult Post([FromBody] dynamic request)
and no luck, I'm keep getting "Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at..."没有运气,我不断收到“跨源请求被阻止:同源策略不允许在...读取远程资源”
Maybe someone can help me?也许有人可以帮助我?
I know this is too late, but can help someone,我知道这为时已晚,但可以帮助某人,
using CorsMiddleware in specified order is matters按指定顺序使用 CorsMiddleware 很重要
app.UseRouting();
app.UseCors("AllowAll");
app.UseAuthorization();
app.UseResponseCaching();
