## 快速开始
|
||
|
||
### 安装
|
||
|
||
```bash
|
||
go get github.com/go-common
|
||
```
|
||
|
||
### 使用示例
|
||
|
||
#### 数据库迁移
|
||
|
||
```go
|
||
import "github.com/go-common/migration"
|
||
|
||
migrator := migration.NewMigrator(db)
|
||
migrator.AddMigration(migration.Migration{
|
||
Version: "20240101000001",
|
||
Description: "create_users_table",
|
||
Up: func(db *gorm.DB) error {
|
||
return db.Exec("CREATE TABLE users ...").Error
|
||
},
|
||
})
|
||
migrator.Up()
|
||
```
|
||
|
||
#### 日期转换
|
||
|
||
```go
|
||
import "github.com/go-common/datetime"
|
||
|
||
datetime.SetDefaultTimeZone(datetime.AsiaShanghai)
|
||
now := datetime.Now()
|
||
str := datetime.FormatDateTime(now)
|
||
```
|
||
|
||
#### HTTP响应
|
||
|
||
```go
|
||
import "github.com/go-common/http"
|
||
|
||
http.Success(w, data)
|
||
http.SuccessPage(w, list, total, page, pageSize)
|
||
http.Error(w, 1001, "业务错误")
|
||
```
|
||
|
||
#### 中间件
|
||
|
||
```go
|
||
import (
|
||
"github.com/go-common/middleware"
|
||
"github.com/go-common/http"
|
||
)
|
||
|
||
// CORS + 时区中间件
|
||
chain := middleware.NewChain(
|
||
middleware.CORS(),
|
||
middleware.Timezone,
|
||
)
|
||
handler := chain.ThenFunc(yourHandler)
|
||
|
||
// 在处理器中获取时区
|
||
timezone := http.GetTimezone(r)
|
||
```
|
||
|
||
#### 配置管理
|
||
|
||
```go
|
||
import "github.com/go-common/config"
|
||
|
||
// 从文件加载配置
|
||
cfg, err := config.LoadFromFile("./config.json")
|
||
|
||
// 获取各种配置
|
||
dsn, _ := cfg.GetDatabaseDSN()
|
||
redisAddr := cfg.GetRedisAddr()
|
||
corsConfig := cfg.GetCORS()
|
||
```
