angular - IdentityServer 外部身份验证提供程序 - 身份验证回调 - 重定向 - 400 错误请求

Question

我正在关注 https://www.scottbrady91.com/Angular/SPA-Authentiction-using-OpenID-Connect-Angular-CLI-and-oidc-client和https://www.scottbrady91.com/Angular/Migrating-oidc -client-js-to-use-the-OpenID-Connect-Authorization-Code-Flow-and- PKCE 在 SPA（Angular）中实现 OIDC

我正在使用 aspboilerplate 集成 IdentityServer

我已经按照上述文章设置了所有内容，并且能够导航到外部身份验证提供程序，并且还能够输入所需的凭据。

在重定向到 Angular 时，我收到 400 - 错误请求。这是详细信息

请让我知道可能出了什么问题

编辑：到目前为止我发现的是

1. 即使使用另一个 Angular oidc 客户端angular-auth-oidc-client，我也陷入了同样的错误
2. 使用 JS 客户端（https://github.com/IdentityServer/IdentityServer4/tree/master/samples/Quickstarts/6_JavaScriptClient），它按预期工作。但由于我们有 Angular 作为前端，我通过包含所需的 JS 库在 Angular 中实现了 JS 示例，令我惊讶的是，我面临同样的问题

3. 当我复制 URL 并粘贴到另一个浏览器中时，call-back会调用该组件。所以看起来 Header & Cookie 有问题。这是我从 Fiddler 收到的请求的完整数据

   HTTP/1.1 400 错误请求连接：关闭

这是我在浏览器中看到的

Answer 1

正如您已经发现确切的问题是标题限制并通过限制 cookie 大小来解决它，但限制 cookie 大小可能不是每次都可以解决的问题。angular 不接受大标题数据的主要原因是 bcs angular 使用 node servewebpack-dev-server和那里是节点 js 中标头大小的限制，您可以在下面找到相关问题

存在大型 cookie 时，ng serve 无法提供页面

由于节点将标头大小限制为 8kB，导致 400 错误请求

更新 npm run 以修复最新 nodejs 版本中的 hpe_header_overflow

使 HTTP_MAX_HEADER_SIZE 可配置

所以不要使用ng serveusing 命令

node --max-http-header-size=16385 ./node_modules/@angular/cli/bin/ng serve

应该是您问题的解决方案

Answer 2

出于某种原因，Angular 不接受那么多数据（Cookie）作为 Header 的一部分。虽然这适用于 JS 客户端，但我不确定为什么 Angular 会发生这种情况。

Account/ExternalController.cs在开发的初始阶段，出于某种原因，我在IdentityServer中注释掉了以下几行

// delete temporary cookie used during external authentication
await HttpContext.SignOutAsync(IdentityServer4.IdentityServerConstants.ExternalCookieAuthenticationScheme);

当这一行被注释掉时，将会有额外的 Cookie 在回调期间发布到 Angular。

取消注释上述行将删除临时 Cookie，并且在回调期间将有更少的标头数据，它会调用相应的 Angular 回调组件并设置不记名令牌。

需要澄清

1. 如果有人可以分享为什么 Angular 在与 JS 客户端完美配合的情况下不接受大型标头数据。
2. 尽管 Angular 说请求错误，但我无法找到引发此错误的位置（Angular 中的哪一层）。我什至没有看到一行错误，我可以从中得到一些关于错误原因的提示（大标题数据）

如果一些专家可以分享他们在上述几点上的经验，那么了解 Angular 的工作原理将非常有帮助。

如果由于任何原因，您无法限制标头大小，则增加节点的 --max-http-header-size。请参阅 https://stackoverflow.com/a/57667786/2922388了解如何操作。

Answer 3

只需尝试一些修复即可。首先 -RedirectUris似乎可疑，因为它包含多个值， - 根据http://docs.identityserver.io/en/latest/topics/clients.html - 声明这List<string>可能是问题的根源。

接下来，以服务器端配置为例https://github.com/IdentityServer/IdentityServer4.Demo/blob/master/src/IdentityServer4Demo/Config.cs

    new Client
    {
       ...
        RequireClientSecret = false,
        RequireConsent = false,

        AllowedGrantTypes = GrantTypes.Code,
        AllowedScopes = { "openid", "profile", "email", "api" },

        AllowOfflineAccess = true,
        RefreshTokenUsage = TokenUsage.ReUse

    }

让我们假设AllowedScopes应该包括强制email范围，然后GetIdentityResources()需要最后修复：

    public static IEnumerable<IdentityResource> GetIdentityResources()
    {
        return new List<IdentityResource>
        {
            new IdentityResources.OpenId(),
            new IdentityResources.Profile(),
            new IdentityResources.Email(),
        };
    }

由于 SPA 代码超出了此处的范围，因此要正确执行流程，请遵循以下示例：

https://github.com/IdentityServer/IdentityServer4.Demo/ ,

Answer 4

也许您在路由或redirect_url配置中混淆了一些东西？

根据您发布的客户端和服务器的配置，redirect_url应该是：

http://localhost:4200/auth-callback `

然而，在截图路径是/call-back，不是/auth-callback。

我会检查配置（客户端和服务器）和 Angular 路由器是否都/auth-callback配置了相同的路径。
