如何在.NET Core 2中設置AuthenticationScheme和AutomaticAuthenticate？

Question

我試圖按照本指南中的.NET核心運行測試時，讓用戶的登錄2

http://geeklearning.io/how-to-deal-with-identity-when-testing-an-asp-net-core-application/

它說我應該用於測試目的，這樣的配置認證中間件：

public class TestAuthenticationOptions : AuthenticationOptions 
{ 
    public virtual ClaimsIdentity Identity { get; } = new ClaimsIdentity(new Claim[] 
    { 
     new Claim("http://schemas.xmlsoap.org/ws/2005/05/identity/claims/nameidentifier", Guid.NewGuid().ToString()), 
     new Claim("http://schemas.microsoft.com/identity/claims/tenantid", "test"), 
     new Claim("http://schemas.microsoft.com/identity/claims/objectidentifier", Guid.NewGuid().ToString()), 
     new Claim("http://schemas.xmlsoap.org/ws/2005/05/identity/claims/givenname", "test"), 
     new Claim("http://schemas.xmlsoap.org/ws/2005/05/identity/claims/surname", "test"), 
     new Claim("http://schemas.xmlsoap.org/ws/2005/05/identity/claims/upn", "test"), 
    }, "test"); 

    public TestAuthenticationOptions() 
    { 
     this.AuthenticationScheme = "TestAuthenticationMiddleware"; 
     this.AutomaticAuthenticate = true; 
    } 
} 

由於AuthenticationOptions類已將AuthenticationScheme和AutomaticAuthenticate屬性從.NET Core 2 cf中的AuthenticationOptions實例中刪除，因此這不起作用。 https://docs.microsoft.com/en-us/aspnet/core/migration/1x-to-2x/identity-2x#setting-default-authentication-schemes

所以，現在我不知道怎麼去登錄在測試中的.NET核心2

你不能這樣做是爲了工作方式了。 AuthenticationScheme只能在Startup.cs中設置。像你這樣分支是不可能的。 而不是測試計劃，您應該使用您的應用程序中使用的計劃。

public class TestAuthenticationOptions : AuthenticationOptions 
{ 
public virtual ClaimsIdentity Identity { get; } = new ClaimsIdentity(new Claim[] 
{ 
    new Claim("http://schemas.xmlsoap.org/ws/2005/05/identity/claims/nameidentifier", Guid.NewGuid().ToString()), 
    new Claim("http://schemas.microsoft.com/identity/claims/tenantid", "test"), 
    new Claim("http://schemas.microsoft.com/identity/claims/objectidentifier", Guid.NewGuid().ToString()), 
    new Claim("http://schemas.xmlsoap.org/ws/2005/05/identity/claims/givenname", "test"), 
    new Claim("http://schemas.xmlsoap.org/ws/2005/05/identity/claims/surname", "test"), 
    new Claim("http://schemas.xmlsoap.org/ws/2005/05/identity/claims/upn", "test"), 
}, "<ProductionScheme>"); 

    public TestAuthenticationOptions 
    { 
     //nothing to do here. 
    } 
} 

在啓動你希望：

services.AddAuthentication("<ProductionScheme>"); 

也許這可以幫助你：

Answer 2

您可以設置配置選項在startup.cs

services.AddAuthentication(config => { 
    this.AuthenticationScheme = "TestAuthenticationMiddleware"; 
    this.AutomaticAuthenticate = true; 
}); 

我在.net core 2.0中找到的大多數代碼都使用這種方式來配置AuthenticationOptions。但是如果你需要創建自己的AuthenticationOptions類並使用。您可以制定自己的計劃，這意味着您還需要製作AuthenticationHandler<TestAuthenticationOptions>課程（讓我們稱之爲TestAuthenticationHandler）並將其添加爲計劃。

services.AddAuthentication(config => { 
    this.AuthenticationScheme = "TestAuthenticationMiddleware"; 
    this.AutomaticAuthenticate = true; 
}) 
.AddScheme<TestAuthenticationHandler, TestAuthenticationOptions>("TestAuthenticationMiddleware", o => {});
