ASP.NET Core分布式项目实战（Consent Controller Get请求逻辑实现）--学习笔记

任务20：Consent Controller Get请求逻辑实现

接着上一节的思路，实现一下 ConsentController

根据流程图在构造函数注入 IClientStore，IResourceStore，IIdentityServerInteractionService

构造函数

private readonly IClientStore _clientSotre;private readonly IResourceStore _resourceStore;private readonly IIdentityServerInteractionService _identityServerInteractionService;private ConsentController(IClientStore clientStore,IResourceStore resourceStore,IIdentityServerInteractionService identityServerInteractionService){_clientSotre = clientStore;_resourceStore = resourceStore;_identityServerInteractionService = identityServerInteractionService;}

Index

public IActionResult Index(string returnUrl){var model = BuildConsentViewModel(returnUrl);if (model == null){}return View(model);}

BuildConsentViewModel

private async Task<ConsentViewModel> BuildConsentViewModel(string returnUrl){var request = await _identityServerInteractionService.GetAuthorizationContextAsync(returnUrl);if (request == null)return null;var client = await _clientSotre.FindEnabledClientByIdAsync(request.ClientId);var resources = await _resourceStore.FindEnabledResourcesByScopeAsync(request.ScopesRequested);return CreateConsentViewModel(request, client, resources);}

CreateConsentViewModel

private ConsentViewModel CreateConsentViewModel(AuthorizationRequest request, Client client, Resources resources){var vm = new ConsentViewModel();vm.ClientName = client.ClientName;vm.ClientLogoUrl = client.LogoUri;vm.ClientUrl = client.ClientUri;vm.AllowRemeberConsent = client.AllowRememberConsent;vm.IdentityScopes = resources.IdentityResources.Select(i => CreateScopeViewModel(i));vm.ResourceScopes = resources.ApiResources.SelectMany(i => i.Scopes).Select(x => CreateScopeViewModel(x));return vm;}

在获取 vm.ResourceScopes 的时候我们用到了 SelectMany，如果我们使用 resources.ApiResources.Select 的话，我们会得到一个 List<List>，而我们想要得到的是一个 List，所以通过 SelectMany 会把 List<List> 展开得到里面的每一个 List

CreateScopeViewModel

private ScopeViewModel CreateScopeViewModel(IdentityResource identityResource){return new ScopeViewModel{Name = identityResource.Name,DisplayName = identityResource.DisplayName,Description = identityResource.Description,Required = identityResource.Required,Checked = identityResource.Required,Emphasize = identityResource.Emphasize,};}private ScopeViewModel CreateScopeViewModel(Scope scope){return new ScopeViewModel{Name = scope.Name,DisplayName = scope.DisplayName,Description = scope.Description,Required = scope.Required,Checked = scope.Required,Emphasize = scope.Emphasize,};}
