配置核心以允许使用ASP.NET Core(Asp.net 5，MVC6，VNext)的所有子域 [英] Configure cors to allow all subdomains using ASP.NET Core (Asp.net 5, MVC6, VNext)

问题描述

我在ASP.NET Core Web应用程序中正确设置了cors.我正在使用以下程序包...

I have cors setup correctly in an ASP.NET Core web app. Im using the following package...

"Microsoft.AspNet.Cors": "6.0.0-rc1-final"

这是startup.cs片段...

and here is the startup.cs snippet...

public virtual IServiceProvider ConfigureServices(IServiceCollection services)
{
    services.AddCors
    (
        options =>
        {
            options.AddPolicy
            (
                CORSDefaults.PolicyName, 
                builder =>
                {
                    //From config...
                    var allowedDomains = new []{"http://aaa.somewhere.com","https://aaa.somewhere.com","http://bbb.somewhere.com","https://bbb.somewhere.com"};

                    //Load it
                    builder
                        .WithOrigins(allowedDomains)
                        .AllowAnyHeader()
                        .AllowAnyMethod()
                        .AllowCredentials();
                }
            );
        }
    );
}

这很好用，只不过允许的子域列表增长很快，而我想允许"somewhere.com"的所有子域.类似于"* .somewhere.com".我似乎在新的ASP.NET Core(MVC6，ASP.NET5，VNext)中找不到有关如何执行此操作的任何文档.我发现的所有文档/示例都演示了如何执行此操作，这些文档/示例适用于MVC或WebApi的早期版本.如何在新堆栈中实现这一目标?

This works great except that the list of subdomains to allow is growing fast and I want to allow all subdomains of "somewhere.com". Something like "*.somewhere.com". I cant seem to find any documentation on how to do this in the new ASP.NET Core (MVC6, ASP.NET5, VNext). All the docs/examples I'm finding that demonstrate how to do this are for earlier versions of MVC or WebApi. How can I achieve this in the new stack?

推荐答案

现在已在2.0.0版中实现.在您的ConfigureServices中，使用以下命令:

This has now been implemented in version 2.0.0. In your ConfigureServices use the following:

options.AddPolicy("MyCorsPolicy",
   builder => builder
      .SetIsOriginAllowedToAllowWildcardSubdomains()
      .WithOrigins("https://*.mydomain.com")
      .AllowAnyMethod()
      .AllowCredentials()
      .AllowAnyHeader()
      .Build()
   );

此外，不要忘记在您的Configure通话中也致电UseCors:

Also, don't forget to call UseCors in your Configure call too:

app.UseCors("MyCorsPolicy");
