推荐答案

打开angular.json文件.我们可以看到默认情况下的配置，该配置将针对您各自的环境在生产添加代码段中显示.在开发环境中添加environment.dev.ts文件，为qa添加environment.qa.ts.根据您的喜好命名. 使用

Open angular.json file. we can see the configurations by default it will be shown for production add code snippet for your respective environments. add environment.dev.ts file in environment for dev, add environment.qa.ts for qa. Name as you prefered. use

 ng serve --configuration=environment_name

environment_name-(dev，qa，prod)ng构建可以遵循相同的过程

environment_name - (dev,qa,prod) same process can be followed for ng build
