B2C和Azure App Service的CORS问题 [英] CORS problem with B2C and Azure App Service

问题描述

我通过在控制器中使用AddCors和EnableCors在我的ASP.NET/Angular应用程序中启用了CORS.我的应用程序正在与AD B2C页面通信.构建后，我在控制台中遇到此错误:

I have enabled CORS in my ASP.NET/Angular application by using AddCors and EnableCors in controllers. My application is communicating with AD B2C pages. After build I have this error in the console :

通过' https://XXX.b2clogin.com/访问XMLHttpRequest(已重定向)来自' https://XXX.azurewebsites.net/User/Info ')" https://XXX.azurewebsites.net "已被CORS政策禁止:否请求中存在"Access-Control-Allow-Origin"标头资源.

Access to XMLHttpRequest at 'https://XXX.b2clogin.com/ (redirected from 'https://XXX.azurewebsites.net/User/Info') from origin 'https://XXX.azurewebsites.net' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

Startup.cs:

Startup.cs :

            services.AddCors(options =>
        {
            options.AddPolicy("CorsPolicy",
                builder => builder.AllowAnyOrigin()
                .AllowAnyMethod()
                .AllowAnyHeader()
                .AllowCredentials());
        });

控制器:

[EnableCors("CorsPolicy")]
[Authorize]
public class UserEditController : Controller

我也通过以下方式在Azure上启用了CORS: Allowed Origins-* .

I have enabled CORS on Azure too by putting : Allowed Origins - * .

更新:

[Route("User/Info")]
[HttpGet]
public async Task<IActionResult> LoggedInUserInfo()
{
    if (User.Identity.IsAuthenticated)
    {
        var user = ((ClaimsIdentity)User.Identity).FindFirst(ClaimTypes.NameIdentifier).Value;
        var viewmodel = await userService.GetUserByObjectId(user);
        return Json(new { loggedIn = "true", user = viewmodel });
    }
    return Json(new { loggedIn = "false" });
}

推荐答案

您似乎正在尝试来自 https://xxx.azurewebsites.net/ 域添加到

It appears that you're attempting a cross-origin request from the https://xxx.azurewebsites.net/ domain to the https://xxx.b2clogin.com/ domain.

当前 .b2clogin.com 域不允许来自任何其他域的任何跨域请求.

Currently the .b2clogin.com domain doesn't allow any cross-origin requests from any other domain.
