json - Azure 应用服务中的授权规则不起作用

Question

我按照 this blog post 上的说明进行操作尝试启用对主页的匿名访问，并在使用此authorization.json 访问/Admin 页面时重定向到Google。

{
  "routes": [
    {
      "path_prefix": "/",
      "policies": { "unauthenticated_action": "AllowAnonymous" }
    },
    {
      "path_prefix": "/Admin",
      "policies": { "unauthenticated_action": "RedirectToLoginPage" }
    }
  ]
}

当我访问主页@ http://mysite.azurewebsites.net/时它总是引导我进入登录页面。在我登录然后发布重定向后，我在日志流中收到以下错误。

其他详细信息。1.如上所述从 Visual Studio 发布后重新启动网站。2. 我在 AdminController 中拥有的那些/Admin 路径。3.authorization.json位于站点的根目录下。如果我导航到 PS D:\home\site\wwwroot>，我可以看到authorization.json 文件。

我不知道我在文件语法方面犯了什么错误。

根据你的描述，我关注了URL Authorization Rules并在我的 Visual Studio 中创建了authorization.json。我可以让它在我的 Azure Web 应用程序上按预期工作。

我认为您的authorization.json 文件有问题。我发现了关于 Encountered unexpected character ‘ï’ error serializing JSON 的类似问题，你可以引用一下。

这是我的authorization.json 文件:

请确保您已在 Azure 门户上应用服务的身份验证/授权边栏选项卡中的“请求未经身份验证时采取的操作”下选择允许匿名请求(无操作)。
