在项目的“云存储桶”列表中，您将找到一个名为artifacts.[project-id].appspot.com的桶。在那里，您会找到部署到App Engine的容器映像。

但是，App Engine提供按需服务器设置和扩展。这意味着，当请求开始进入时，将创建App Engine实例；如果流量增加，则将创建更多实例。

每个实例将分别加载您应用的图片。

在这种类型的环境中，您不应将任何相关信息存储在App的目录中，因为当实例由于流量不足而被杀死时，所有信息都将被擦除，并且在一个实例中存储的数据将不可用。其他情况。有关更多信息，请参见how instances are managed。

如果您希望应用程序将数据存储在SQL数据库中，则可以查看Cloud SQL，或者，您可能会发现Cloud Firestore（这是一个NoSQL数据库）可以满足您的要求。需要。这是list of GCP databases

用于创建角度项目的链接 – https://docs.microsoft.com/en-us/aspnet/core/spa/angular?view=aspnetcore-2.1&tabs=visual-studio

现在我按照链接更新到Angular 6 How to update / upgrade from Angular 4 to Angular 5+

使用另一个链接进行更新,但所有链接都显示相同的错误
https://asish.com.au/how-to-upgrade-angular-5-application-to-angular-6-with-visual-studio-2017/

https://update.angular.io/

但是得到很多错误

处理请求时发生未处理的异常.
AggregateException：发生一个或多个错误. (发生了一个或多个错误.(NPM脚本’start’退出但未指示Angular CLI正在侦听请求.错误输出为：UnkNown选项：’ – extraxtCss’
))

错误详情

任何人都可以让我知道如何通过适当的链接将角度5.2转换为角度6

dotnet new angular -o my-new-app
cd my-new-app
cd ClientApp
npm install

首先,使用以下命令将Angular CLI全局更新为最新版本：

npm install -g @angular/cli

接下来,我们需要更新特定于应用程序的Angular CLI本地版本.为此,请导航到Angular应用程序根文件夹(package.json所在的位置)并运行以下命令.

npm install @angular/cli

Angular CLI现在支持包含多个项目的工作区,例如多个应用程序或库.因此,现在可以在同一个CLI项目中创建多个应用程序(称为工作空间),并创建库(一组共享的组件,指令,管道和服务)！这个新架构使用angular.json而不是.angular-cli.json进行构建和项目配置.因此,需要删除.angular-cli.json文件,并且需要在项目中添加新的angular.json文件.别担心,您不必手动执行此操作.运行以下命令将配置文件转换为新格式(angular.json).

ng update @angular/cli

成功完成此命令后,您可以在解决方案资源管理器中看到angular.json文件.我必须运行此命令两次以获取新文件.因此,如果您在第一次运行该命令后在解决方案资源管理器中找不到新的angular.json文件,请再试一次.

接下来,是时候将所有框架包升级到Angular 6.为此,请运行以下命令：

ng update @angular/core

所有Angular框架包都升级到Angular 6.您可以通过package.json文件对其进行验证.

接下来,运行ng update以识别和更新其他依赖项.

Angular 6现在依赖于TypeScript 2.7和RxJS 6.因此,我们需要升级RxJS.您将考虑在使用RxJS导入和运算符的任何地方手动更改代码.别担心,有一个包装可以解决这个问题.运行以下命令以升级RxJS.

npm install -g rxjs-tslint
rxjs-5-to-6-migrate -p src/tsconfig.app.json

完成后,删除rxjs-compat.此软件包需要向后兼容版本6之前的RxJS.但是,现在不再需要它,所以让我们使用以下命令将其删除：

npm uninstall rxjs-compat

现在,运行ng来查看应用程序正在构建和运行而没有任何错误.还剩下一件事.如果我们从Visual Studio 2017构建应用程序并运行它,您可能会在浏览器中看到以下异常.
InvalidOperationException：NPM脚本“start”退出,但未指示Angular CLI正在侦听请求.错误输出为：未知选项：’ – extxtCss’

这是因为ng serve命令不再支持–extractCss选项. extractCSS是一个JavaScript库和一个在线工具,可以从HTML文档中提取元素ID,类和内联样式,并将它们输出为CSS样式表.此选项在ng服务上不可用,因为它是与构建相关的选项,而不是与服务相关的选项.

要解决此问题,请从package.json文件的scripts部分中的ng serve命令中删除–extract-css选项.

"start": "ng serve"

保存package.json文件,构建应用程序并再次运行.您应该会在浏览器中看到该应用正在运行

services
  .AddAuthentication(CookieAuthenticationDefaults.AuthenticationScheme)
  .AddCookie(options =>
  {
      options.ExpireTimeSpan = TimeSpan.FromDays(1);
      options.SlidingExpiration = true;
      options.Cookie.Name = "authtoken";
  });

解决方法

services.AddAuthentication("CookieAuthenticationScheme")
    .AddCookie(options => {
        options.Events.OnRedirectToLogin = (context) =>
        {
            context.Response.StatusCode = 401;
            return Task.CompletedTask;
        };
    });

解决方法

services.AddAuthentication()
    .AddGoogle(options => 
    {
        //Set client Id and secret here
        options.ClientId = "clientId_here";
        options.ClientSecret = "ClientSecret_here";
    });
