|
||
## 标准答案
|
||
|
||
### 1. 标准项目结构
|
||
|
||
#### **Standard Go Project Layout**
|
||
|
||
```
|
||
myapp/
|
||
├── cmd/ # 主程序入口
|
||
│ └── myapp/
|
||
│ └── main.go
|
||
├── internal/ # 私有应用代码（不可导入）
|
||
│ ├── app/
|
||
│ ├── model/
|
||
│ └── service/
|
||
├── pkg/ # 公共库（可外部导入）
|
||
│ └── util/
|
||
├── api/ # API 协议定义
|
||
│ └── proto/
|
||
├── web/ # Web 静态资源
|
||
├── configs/ # 配置文件
|
||
├── scripts/ # 构建、安装脚本
|
||
├── test/ # 额外测试数据
|
||
├── docs/ # 文档
|
||
├── tools/ # 工具
|
||
├── go.mod
|
||
├── go.sum
|
||
├── Makefile
|
||
└── README.md
|
||
```
|
||
|
||
---
|
||
|
||
### 2. Go Module
|
||
|
||
#### **初始化 Module**
|
||
|
||
```bash
|
||
go mod init github.com/user/myapp
|
||
```
|
||
|
||
---
|
||
|
||
#### **go.mod 文件**
|
||
|
||
```go
|
||
module github.com/user/myapp
|
||
|
||
go 1.21
|
||
|
||
require (
|
||
github.com/gin-gonic/gin v1.9.1
|
||
github.com/spf13/viper v1.18.2
|
||
)
|
||
```
|
||
|
||
---
|
||
|
||
### 3. 依赖管理
|
||
|
||
#### **添加依赖**
|
||
|
||
```bash
|
||
go get github.com/gin-gonic/gin@latest
|
||
go get github.com/spf13/viper@v1.18.2
|
||
```
|
||
|
||
---
|
||
|
||
#### **升级依赖**
|
||
|
||
```bash
|
||
# 升级所有依赖
|
||
go get -u ./...
|
||
|
||
# 升级特定依赖
|
||
go get -u github.com/gin-gonic/gin
|
||
```
|
||
|
||
---
|
||
|
||
#### **清理未使用的依赖**
|
||
|
||
```bash
|
||
go mod tidy
|
||
```
|
||
|
||
---
|
||
|
||
### 4. 构建和发布
|
||
|
||
#### **构建应用**
|
||
|
||
```bash
|
||
# 构建
|
||
go build -o bin/myapp ./cmd/myapp
|
||
|
||
# 交叉编译
|
||
GOOS=linux GOARCH=amd64 go build -o bin/myapp-linux ./cmd/myapp
|
||
```
|
||
|
||
---
|
||
|
||
#### **Docker 多阶段构建**
|
||
|
||
```dockerfile
|
||
# 构建
|
||
FROM golang:1.21-alpine AS builder
|
||
WORKDIR /app
|
||
COPY go.mod go.sum ./
|
||
RUN go mod download
|
||
COPY . .
|
||
RUN CGO_ENABLED=0 go build -o myapp ./cmd/myapp
|
||
|
||
# 运行
|
||
FROM alpine:latest
|
||
WORKDIR /root/
|
||
COPY --from=builder /app/myapp .
|
||
CMD ["./myapp"]
|
||
```
|
||
|
||
---
|
||
|
||
### 5. CI/CD 最佳实践
|
||
|
||
#### **GitHub Actions**
|
||
|
||
```yaml
|
||
name: CI
|
||
|
||
on:
|
||
push:
|
||
branches: [ main ]
|
||
|
||
jobs:
|
||
test:
|
||
runs-on: ubuntu-latest
|
||
steps:
|
||
- uses: actions/checkout@v3
|
||
|
||
- name: Set up Go
|
||
uses: actions/setup-go@v4
|
||
with:
|
||
go-version: '1.21'
|
||
|
||
- name: Install dependencies
|
||
run: go mod download
|
||
|
||
- name: Run tests
|
||
run: go test -v -race -coverprofile=coverage.out ./...
|
||
|
||
- name: Upload coverage
|
||
uses: codecov/codecov-action@v3
|
||
with:
|
||
files: ./coverage.out
|
||
```
|
