先决条件:设置AWS放大CLI。

1.项目初始化。

amplify init：安装AWS放大本地和远程。

注意:放大init命令找不到

1)`npm install -g @aws-amplify/cli` - ### install the Amplify CLI ###
2)`curl -sL https://aws-amplify.github.io/amplify-cli/install | bash && $SHELL` ### configured $Path correctly ###
3)`amplify init` ###Try Amplify init###

Amplify Demo project or click enter for the default name：输入项目名称

Dev or click enter for the default name：为环境输入一个名称

Choose Visual Studio Code：选择默认编辑器

iOS：选择您正在构建的应用程序类型

yes：您想使用AWS配置文件吗？

2.项目存储设置

amplify add storage：添加存储

Content(Images, audio, video, etc.)：选择下面提到的服务

yes：(亚马逊-科尼图)你现在想添加auth吗？

No：您要配置高级设置吗？

bucket name or click enter for the default name：请提供桶名

Auth users only or Auth and guest users：谁应该有权限

create/update , read , delete.：通过身份验证的用户需要什么样的访问？

create/update , read , delete.：您想为客人用户提供什么样的访问？

No：你想为你的S3桶添加一个喇嘛触发器吗？

3.向后端推挽放大配置

amplify push：放大推

Yes：你确定要继续吗？
