本地调试

下载代码在本地调试，请参考微信云托管本地调试指南

实时开发

代码变动时，不需要重新构建和启动容器，即可查看变动后的效果。请参考微信云托管实时开发指南

Dockerfile最佳实践

请参考如何提高项目构建效率

项目结构说明

.
├── Dockerfile
├── README.md
├── container.config.json
├── db.js
├── index.js
├── index.html
├── package.json
  • index.js：项目入口，实现主要的读写 API
  • db.js：数据库相关实现，使用 sequelize 作为 ORM
  • index.html：首页代码
  • package.json：Node.js 项目定义文件
  • container.config.json：模板部署「服务设置」初始化配置（二开请忽略）
  • Dockerfile：容器配置文件

服务 API 文档

POST /guanhai_ticket

请求参数

expire_seconds: int scene_str: string

响应结果

  • code：错误码
  • data：当前计数值
响应结果示例
{
  "ticket": xxxxx,
  "expire_seconds": xx,
  "url": "http://xxxx",
}

vscode插件

  • Weixin Cloudbase Docker Extension
    安装之后，在设置中搜索"wxcloud", 设置Appid和CLI key

Ubuntu安装Docker

sudo apt update
sudo apt install apt-transport-https ca-certificates curl gnupg lsb-release
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg
sudo apt update
sudo apt install docker-ce docker-ce-cli containerd.io
sudo systemctl start docker
sudo docker run hello-world

权限问题(docker报错：ERROR: Got permission denied)

  • 第一次切换到root
    sudo passwd root
  • su root
phong@phong-virtual-machine:~/Desktop/express-ticket$ su root
Password:
root@phong-virtual-machine:/home/phong/Desktop/express-ticket# sudo groupadd docker
groupadd: group 'docker' already exists
root@phong-virtual-machine:/home/phong/Desktop/express-ticket# sudo gpasswd -a phong docker
Adding user phong to group docker
root@phong-virtual-machine:/home/phong/Desktop/express-ticket# newgrp docker
root@phong-virtual-machine:/home/phong/Desktop/express-ticket# su phong
phong@phong-virtual-machine:~/Desktop/express-ticket$ docker ps

启动Proxy nodes for VPC access

启动api.weixin.qq.com容器

Executing task: docker run  --rm -d --network wxcb0 --name api.weixin.qq.com --pull=always -e TOAL_ROLE=client -e TOAL_SERVER=https://wxcloud-localdebug-proxy-68063-4-1320492701.sh.run.tcloudbase.com:443 -e TOAL_KEY=TOAL_j8h4uqhl5m -e TOAL_SERVER_TIMEOUT=200 -e TOAL_MODE=shortpoll -e TOAL_LOCAL_PORT=80 -e TOAL_TARGET=api.weixin.qq.com -e TOAL_VERBOSE=DEBUG -l role=vpcdebugproxy -l wxcloud=api.weixin.qq.com -l domain=api.weixin.qq.com ccr.ccs.tencentyun.com/tcb_prd/wxcloud-localdebug-proxy:latest

将项目打包成容器

phong@phong-virtual-machine:~/Desktop/express-ticket$ docker run --rm --network wxcb0 -p 8080:80 -it -v /home/phong/Desktop/express-ticket:/app alpine:3.13 /bin/sh
/ # cd app
/app # ls
Dockerfile             README.md              db.js                  index.js
LICENSE                container.config.json  index.html             package.json

安装Dockerfile中的命令，安装依赖，运行

sed -i 's/dl-cdn.alpinelinux.org/mirrors.tencent.com/g' /etc/apk/repositories \
apk add --update --no-cache nodejs npm
npm install
npm start

访问8080端口的ticket接口

http://Linux的IP地址:8080/ticket 返回：

{
    "ticket": "xxx",
    "expire_seconds": xxx,
    "url": "http://weixin.qq.com/q/xxx"
}
