AuthorizationBuilder.SetFallbackPolicy(AuthorizationPolicy) 方法

定义

命名空间:

Microsoft.AspNetCore.Authorization

程序集:

Microsoft.AspNetCore.Authorization.dll

包:

Microsoft.AspNetCore.Authorization v8.0.0

Source:

AuthorizationBuilder.cs

设置未提供 IAuthorizeData 时使用的 CombineAsync(IAuthorizationPolicyProvider, IEnumerable<IAuthorizeData>) 回退授权策略。 因此，如果资源没有 IAuthorizeData 实例，AuthorizationMiddleware 将使用回退策略。 如果资源具有任何 IAuthorizeData 资源，则评估它们，而不是回退策略。 默认情况下，回退策略为 null，通常不起作用，除非管道中有 AuthorizationMiddleware。 默认 IAuthorizationService不会以任何方式使用它。

public virtual Microsoft.AspNetCore.Authorization.AuthorizationBuilder SetFallbackPolicy (Microsoft.AspNetCore.Authorization.AuthorizationPolicy? policy);

abstract member SetFallbackPolicy : Microsoft.AspNetCore.Authorization.AuthorizationPolicy -> Microsoft.AspNetCore.Authorization.AuthorizationBuilder
override this.SetFallbackPolicy : Microsoft.AspNetCore.Authorization.AuthorizationPolicy -> Microsoft.AspNetCore.Authorization.AuthorizationBuilder

Public Overridable Function SetFallbackPolicy (policy As AuthorizationPolicy) As AuthorizationBuilder
