服务器

编写 Dockerfile.dev

FROM golang:1.14
WORKDIR workspace
# 阿里云
RUN go env -w GO111MODULE=on
RUN go env -w GOPROXY=https://mirrors.aliyun.com/goproxy/,direct
# debug
RUN go get github.com/go-delve/delve/cmd/dlv
# live reload
RUN go get -u github.com/cosmtrek/air
# copy modules manifests
COPY go.mod go.mod
COPY go.sum go.sum
# cache modules
RUN go mod download

构建本地开发 Image

docker build -f Dockerfile.dev -t scmj-server:dev .

编写 mysql.cnf

编写 docker-compose.mysql.yaml

version: "3.7"
services:
  db:
    image: mysql:5.7
    volumes:
      - db_data:/var/lib/mysql
      - ./mysql.cnf:/etc/mysql/my.cnf
    networks:
      - db_network
    ports:
      - "3306:3306"
    restart: always
    environment:
      MYSQL_ROOT_PASSWORD: 123456
      MYSQL_DATABASE: scmj
      MYSQL_USER: scmj
      MYSQL_PASSWORD: scmj
      TZ: Asia/Shanghai
  adminer:
    depends_on:
      - db
    image: adminer
    restart: always
    networks:
      - db_network
    ports:
      - 8086:8080
networks:
  db_network:
    driver: "bridge"
volumes:
    db_data: {}

一键启动 MySql 和 Adminer

docker-compose -f docker-compose.mysql.yaml up -d

登录 Adminer 管理界面

我们进入 http://localhost:8086，使用如下配置登录：

MySQLdbroot123456scmj

加入 launch.json

方便 VSCode 调试

{
  "version": "0.2.0",
  "configurations": [
      {
          "name": "nanoserver",
          "type": "go",
          "request": "launch",
          "mode": "remote",
          "remotePath":"/workspace/app",
          "port": 2345,
          "program": "${workspaceFolder}",
          "env": {
              "GO111MODULE":"on"
          },
          "args": [],
          "trace": "log",
          "showLog": true
      }
  ]
}

加入 .air.toml

# Config file for [Air](https://github.com/cosmtrek/air) in TOML format

# Working directory
# . or absolute path, please note that the directories following must be under root.
root = "."
tmp_dir = "tmp"

[build]
# Just plain old shell command. You could use `make` as well.
cmd = "go build -o ./tmp/main ."
# Binary file yields from `cmd`.
bin = "tmp/main"
# Customize binary.
full_bin = "APP_ENV=dev APP_USER=air ./tmp/main"
# Watch these filename extensions.
include_ext = ["go", "tpl", "tmpl", "html"]
# Ignore these filename extensions or directories.
exclude_dir = ["assets", "tmp", "vendor", "frontend/node_modules"]
# Watch these directories if you specified.
include_dir = []
# Exclude files.
exclude_file = []
# This log file places in your tmp_dir.
log = "air.log"
# It's not necessary to trigger build each time file changes if it's too frequent.
delay = 1000 # ms
# Stop running old binary when build errors occur.
stop_on_error = true
# Send Interrupt signal before killing process (windows does not support this feature)
send_interrupt = false
# Delay after sending Interrupt signal
kill_delay = 500 # ms

[log]
# Show log time
time = false

[color]
# Customize each part's color. If no color found, use the raw app log.
main = "magenta"
watcher = "cyan"
build = "yellow"
runner = "green"

[misc]
# Delete tmp directory on exit
clean_on_exit = true

编写 docker-compose.dev.yaml

version: "3.4"
services:
  scmj:
    image: scmj-server:dev
    command: >
      bash -c "cp ./go.mod ./go.sum app/
      && cd app/
      && ls -la
      && air -c .air.toml -d"
    volumes:
    - ./:/workspace/app
    networks:
      - db_network
    ports:
      - 12307:12307
      - 33251:33251
  scmj-debug:
    image: scmj-server:dev
    command: >
      bash -c "cp ./go.mod ./go.sum app/
      && cd app/
      && ls -la
      && dlv debug main.go --headless --log -l 0.0.0.0:2345 --api-version=2"
    volumes:
    - ./:/workspace/app
    networks:
      - db_network
    ports:
      - 12307:12307
      - 33251:33251
      - 2345:2345
    security_opt:
      - "seccomp:unconfined"
networks:
  db_network:
    driver: "bridge"

使用 docker-compose 调试

docker-compose -f docker-compose.dev.yaml up scmj-debug

使用 docker-compose 开发

docker-compose -f docker-compose.dev.yaml up scmj

modelschema

XORM 同步数据库

scmj

相关代码是：

....
func syncSchema() {
    database.StoreEngine("InnoDB").Sync2(
        new(model.Agent),
        new(model.CardConsume),
        new(model.Desk),
        new(model.History),
        new(model.Login),
        new(model.Online),
        new(model.Order),
        new(model.Recharge),
        new(model.Register),
        new(model.ThirdAccount),
        new(model.Trade),
        new(model.User),
        new(model.Uuid),
        new(model.Club),
        new(model.UserClub),
    )
}
...

客户端

apk

安装安卓模拟器

这里我推荐网易的 MuMu模拟器。

安装 APK

mahjong.apk，已经放到笔者修改过的项目中。这里我们使用多开助手，开4个空来血战。

客户端登录

我们点击微信登录。

发现登录失败……

解决客户端登录失败问题

当然这问题，也好解决：

apkappConfig.luac

Charles 对客户端请求地址转发

Map Remote

加入 guest 测试渠道 konglai

重新登录进入游戏

完美，搞定。
