如何启用CORS在ASP.NET 5 [英] How to enable CORS in ASP.NET 5

问题描述

我试图启用跨起源资源共​​享我的ASP.NET 5 API，但我卡住了。

I am trying to enable cross origin resources sharing on my ASP.NET 5 API, but I am stuck.

EnableCors 属性接受 policyName 类型字符串作为参数：

The EnableCors attribute accepts policyName of type string as parameter:

// Summary:
//     Creates a new instance of the Microsoft.AspNet.Cors.Core.EnableCorsAttribute.
//
// Parameters:
//   policyName:
//     The name of the policy to be applied.
public EnableCorsAttribute(string policyName);

什么的 policyName 的含义及如何能我配置的 CORS 上的ASP.NET 5 API？

What does the policyName mean and how can I configure CORS on an ASP.NET 5 API?

推荐答案

您必须配置一个CORS政策在该 ConfigureServices 方法，应用程序的启动：

You have to configure a CORS policy at application startup in the ConfigureServices method:

public void ConfigureServices(IServiceCollection services)
{
    services.AddCors(o => o.AddPolicy("MyPolicy", builder =>
    {
        builder.AllowAnyOrigin()
               .AllowAnyMethod()
               .AllowAnyHeader();
    }));

    // ...
}

的

CorsPolicyBuilder 在建设者允许您配置策略您的需求。现在，您可以使用此名称将策略应用到控制器和操作：

The CorsPolicyBuilder in builder allows you to configure the policy to your needs. You can now use this name to apply the policy to controllers and actions:

[EnableCors("MyPolicy")]

或者，它适用于每一个请求：

Or apply it to every request:

public void Configure(IApplicationBuilder app)
{
    app.UseCors("MyPolicy");

    // ...
}
