\n

Demo 实战

\n
    \n
  1. 安装Serverless Framework
    2. \n
\n
npm install -g serverless
\n
    \n
  1. 初始化项目模板
    2. \n
\n
sls init -t websocket-order
\n
    \n
  1. 查看项目目录
    2. \n
\n

下载到本地后，查看项目目录结构如下：

\n

\n

包含 DB、网关、函数等多个子模块。

\n\n
# secret for credential\nTENCENT_SECRET_ID=xxxxxx\nTENCENT_SECRET_KEY=xxxxxx\n\n# global config\nREGION=ap-shanghai
\n
    \n
  1. 项目部署
    2. \n
\n
sls deploy --all
\n
    \n
  1. 更新配置及部署
    2. \n
  2. 执行 initdb-dev 函数，进行数据库初始化。在控制台或者 vscode 插件中，点击测试 initdb-dev 函数，对数据库进行初始化的建表等操作
    3. \n
  3. 更新 apiid 配置，再次部署\n\"serverless\"\n查看输出信息，在 functionbill 目录和 functionws_trans 目录的 serverless.yml 中，分别配置 websocket API 的 apiid ，并重新部署两个函数，刷新环境变量配置。\n\"serverless\"
    4. \n
\n
sls deploy --target=./function_ws_trans \nsls deploy --target=./function_bill
\n
    \n
  1. 更改客户端与厨房订单系统的地址
    2. \n
\n

App点单系统.html 更改 29 行 以及 88 行中 xxxx 为：生成的 API 网关服务域名

\n

店家厨房系统.html 更改 17 行 xxxx 为 API 网关服务域名

\n

效果演示：\n\"效果演示\"

\n

附录：参考文档和配置

\n
    \n
  1. 安装 Serverless Framework
    2. \n
  2. 安装 Serverless DB
    3. \n
  3. API 网关的 yaml 完整配置
    4. \n
  4. SCF 的 yaml 完整配置
    5. \n
\n
