c# – 带有Authorize属性的ASP.NET 5 beta8 CORS无效

2023年3月14日 265次阅读

在beta7中,CORS能够像这样设置：

// in the ConfigurationServices
services.AddMvc();
services.ConfigureCors(options =>
{
    // set cors settings...
});

//...
// in the Startup.Configure method
app.UseCors();
app.UseMvc();

它就像一个魅力,但beta8打破了它.我发现了这个问题：Why Cors doesn’t work after update to beta8 on ASP.NET 5?,并修改如下：

// in Startup.ConfigureServices method
services.AddCors(options =>
{
    options.AddPolicy("CorsPolicy", builder =>
    {
        // allow them all
        builder.AllowAnyHeader();
        builder.AllowAnyMethod();
        builder.AllowAnyOrigin();
        builder.AllowCredentials();
    });
});
services.AddMvc();

//...
// in the Startup.Configure method
app.UseMvc();

//...
// in the Controller
[EnableCors("CorsPolicy")]
public IActionResult Get()
{
    return OK();
}

是的它再次起作用,但是当我添加[Authorize(“Bearer”)]时,控制器通过ajax调用返回401 Unauthorized for OPTIONS请求.这是HTTP请求和响应.

[请求]

OPTIONS https://api.mywebsite.net/ HTTP/1.1
Accept: */*
Origin: https://myanotherwebsite.net
Access-Control-Request-Method: GET
Access-Control-Request-Headers: accept, authorization
Accept-Encoding: gzip, deflate
User-Agent: Mozilla/5.0 (Windows NT 10.0; WOW64; Trident/7.0; Touch; rv:11.0) like Gecko
Host: api.mywebsite.net
Connection: Keep-Alive
Cache-Control: no-cache

[响应]

HTTP/1.1 401 Unauthorized
Content-Length: 0
Server: Microsoft-IIS/8.0
WWW-Authenticate: Bearer
X-Powered-By: ASP.NET
Set-Cookie: ARRAffinity=...;Path=/;Domain=api.mywebsite.net

如何在ASP.NET 5 beta8中使用[Authorization]属性启用CORS？

编辑
我能够使用默认的ASP.NET MV C6模板(beta 8)重现此问题.
当我使用[EnableCors]和[Authorize]装饰控制器或方法时,它返回401 Unauthorized(或302重定向到登录页面).

EDIT2
事实证明,这是我的一个愚蠢的错误.我回答了自己是什么问题.

最佳答案 好吧,这是我的愚蠢错误.我对Microsoft.AspNet.Mvc.Cors和Microsoft.AspNet.Cors感到困惑.

前一个是关于OWIN中间件,另一个是关于Mvc过滤器.我没有在Project.json中添加Microsoft.AspNet.Cors,也没有在Configures()中添加app.UseCors().

ConfigureServices()中的AddCors()和Configure()中的UseCors()都需要协同工作.

这可能是CORS的基本设置.

(在Project.json中)

"dependencies": {
  ...
  "Microsoft.AspNet.Cors": "6.0.0-beta8",
  "Microsoft.AspNet.Mvc.Cors": "6.0.0-beta8",
  ...
}

(在Startup.cs中)

public void ConfigureServices(IServiceCollection services)
{
    services.AddCors(options =>
    {
        options.AddPolicy("CorsPolicy", builder =>
        {
            // ...build cors options...
        });
    });
    services.AddMvc();
}

public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
    app.UseIISPlatformHandler();
    app.UseStaticFiles();
    app.UseCors("CorsPolicy");
    app.UseMvc();
}

或这个：

public void ConfigureServices(IServiceCollection services)
{
    services.AddCors();
    services.AddMvc();
}

public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
    app.UseIISPlatformHandler();
    app.UseStaticFiles();
    app.UseCors(builder =>
    {
        // ...default cors options...
    });
    app.UseMvc();
}

希望没有人像我一样犯愚蠢的错误.
