我正在尝试将我的Web Api2迁移到ASP.NET核心web api项目.在我的项目中,我们使用的是EnableCors功能.
我在Microsoft网站上找到了这个文档,我将其用作参考 – https://docs.asp.net/en/latest/security/cors.html
正如“在MVC中启用CORS”一节中所述,我试图在这样的ConfigureServices menthod中全局启用cors –
services.Configure<Mvcoptions>(options => { options.Filters.Add(new CorsAuthorizationFilterFactory("AllowSpecificOrigin")); });
但是,我收到了这个我无法理解的错误 –
The call is ambiguous between the following methods or properties:
‘Microsoft.Extensions.DependencyInjection.OptionsServiceCollectionExtensions.Configure(Microsoft.Extensions.DependencyInjection.IServiceCollection,
System.Action)’ and
‘Microsoft.Extensions.DependencyInjection.OptionsServiceCollectionExtensions.Configure(Microsoft.Extensions.DependencyInjection.IServiceCollection,
System.Action)’
请参阅错误截图 – ERROR scrrenshot
有谁能告诉我如何在我的ASP.NET核心WebApi项目中全局启用CORS？
