c# - 使用 Azure 应用服务和 Facebook 身份配置 ASP.NET Core Web 应用程序时出错

Question

我的 ASP.Net Core 2.2 应用程序的“Facebook 外部登录设置”可以在我的本地计算机上运行，​​但不能在 Azure 应用服务上运行。我收到一个您无法从不安全的页面获取访问 token 或登录此应用程序。当应用程序重定向到 facebook 时，尝试将页面重新加载为 https:// 错误。不过，我已经在 facebook 配置下设置了应用程序的安全 URL=>“有效的 OAuth 重定向 URI”(请参见下面的屏幕截图)。

我错过了什么？

Startup.cs:

public void ConfigureServices(IServiceCollection services)
{
  services.Configure<ForwardedHeadersOptions>(options =>
  {
    options.ForwardedHeaders = ForwardedHeaders.XForwardedFor | ForwardedHeaders.XForwardedProto;
  });
.............

}
public void Configure(IApplicationBuilder app, IHostingEnvironment env)
    {
      app.UseForwardedHeaders();
    }

根据 this 对输出进行故障排除链接:

Facebook 配置:有效的 OAuth 重定向 URI 显示我的网站配置了 https:

对我有用的是记录的解决方案 here 。还需要在 Microsoft Azure 中添加 ASPNETCORE_FORWARDEDHEADERS_ENABLED=true 应用设置。

//配置服务

if (string.Equals("true", hostingContext.Configuration["ForwardedHeaders_Enabled"], StringComparison.OrdinalIgnoreCase))
            {
                services.Configure<ForwardedHeadersOptions>(options =>
                {
                    options.ForwardedHeaders = ForwardedHeaders.XForwardedFor | ForwardedHeaders.XForwardedProto;
                    // Only loopback proxies are allowed by default. Clear that restriction because forwarders are
                    // being enabled by explicit configuration.
                    options.KnownNetworks.Clear();
                    options.KnownProxies.Clear();
                });
            }
