任務20：Consent Controller Get請求邏輯實現

接著上一節的思路，實現一下 ConsentController

根據流程圖在構造函數注入 IClientStore，IResourceStore，IIdentityServerInteractionService

構造函數

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; }

在獲取 vm.ResourceScopes 的時候我們用到了 SelectMany，如果我們使用 resources.ApiResources.Select 的話，我們會得到一個 List<List>，而我們想要得到的是一個 List，所以通過 SelectMany 會把 List<List> 展開得到里面的每一個 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,}; }

ConsentViewModel 添加 ClientUrl

public string ClientUrl { get; set; }

ScopeViewModel 修改字段類型為 bool

public bool Emphasize { get; set; } public bool Required { get; set; }
