# 开始后端程序开发
|
|||
|
|
|
|||
|
|
## 克隆代码
|
|||
|
|
|
|||
|
|
打开后端的开发容器 IDE, 打开 Terminal，可控你的代码到 `/Code` 目录。
|
|||
|
|
|
|||
|
|
```sh
|
|||
|
|
gh auth login
|
|||
|
|
|
|||
|
|
cd /Code
|
|||
|
|
git clone https://github.com/beclab/terminus-app-demo.git
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
之后便可以在 IDE 中打开后端代码进行开发。
|
|||
|
|
|
|||
|
|
|
|||
|
|
|
|||
|
|
## 连接数据库
|
|||
|
|
|
|||
|
|
在开发容器中，可以通过环境变量获取数据库信息（如果你在部署的时候以环境变量的方式将数据库参数注入容器）。
|
|||
|
|
|
|||
|
|
以 gorm 为例：
|
|||
|
|
```go
|
|||
|
|
import (
|
|||
|
|
"fmt"
|
|||
|
|
"os"
|
|||
|
|
"strconv"
|
|||
|
|
|
|||
|
|
"gorm.io/driver/postgres"
|
|||
|
|
"gorm.io/gorm"
|
|||
|
|
)
|
|||
|
|
|
|||
|
|
|
|||
|
|
func init() {
|
|||
|
|
var err error
|
|||
|
|
|
|||
|
|
db_host = os.Getenv("DB_HOST")
|
|||
|
|
db_port, err = strconv.Atoi(os.Getenv("DB_PORT"))
|
|||
|
|
if err != nil {
|
|||
|
|
panic(err)
|
|||
|
|
}
|
|||
|
|
db_username = os.Getenv("DB_USER")
|
|||
|
|
db_password = os.Getenv("DB_PWD")
|
|||
|
|
db_name = os.Getenv("DB_NAME")
|
|||
|
|
}
|
|||
|
|
|
|||
|
|
|
|||
|
|
func main(){
|
|||
|
|
dsn := fmt.Sprintf("host=%s user=%s password=%s dbname=%s port=%d sslmode=disable TimeZone=Asia/Shanghai",
|
|||
|
|
db_host, db_username, db_password, db_name, db_port)
|
|||
|
|
db, err := gorm.Open(postgres.Open(dsn), &gorm.Config{})
|
|||
|
|
if err != nil {
|
|||
|
|
panic(err)
|
|||
|
|
}
|
|||
|
|
|
|||
|
|
}
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
## 调试
|
|||
|
|
|
|||
|
|
完成代码开发后，便可在 IDE 中运行调试你的代码。
|
|||
|
|
|
|||
|
|
|
|||
|
|
|
|||
|
|
也可以在 Terminal 中运行你的代码，例如：
|
|||
|
|
|
|||
|
|
```sh
|
|||
|
|
go run main.go
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
这时，就可以配合前端完成接口联调。
