连接

安装嬴图Go驱动并部署一个嬴图实例后，就可以将应用与数据库连接了。

你可以使用UltipaConfig配置连接，点击查看UltipaConfig字段。

建立连接

使用sdk.NewUltipaDriver()创建连接：

package main

import (
	"log"

	"github.com/ultipa/ultipa-go-sdk/sdk"
	"github.com/ultipa/ultipa-go-sdk/sdk/configuration"
)

func main() {
	config := &configuration.UltipaConfig{
		// URI example:	Hosts: []string{"mqj4zouys.us-east-1.cloud.ultipa.com:60010"},
		Hosts:    []string{"192.168.1.85:60061", "192.168.1.87:60061", "192.168.1.88:60061"},
		Username: "<usernmae>",
		Password: "<password>",
	}

	driver, err := sdk.NewUltipaDriver(config)
	if err != nil {
		log.Fatalln("Failed to connect to Ultipa:", err)
	}
	isSuccess, _ := driver.Test(nil)
	println(isSuccess)
}

true

使用配置文件

本例演示如何使用配置文件（config.yml）建立连接：

package main

import (
	"log"

	"github.com/ultipa/ultipa-go-sdk/sdk"
	"github.com/ultipa/ultipa-go-sdk/sdk/configuration"
)

func main() {
	config, _ := configuration.LoadConfigFromYAML("./config.yml")

	driver, err := sdk.NewUltipaDriver(config)
	if err != nil {
		log.Fatalln("Failed to connect to Ultipa:", err)
	}
	isSuccess, _ := driver.Test(nil)
	println(isSuccess)
}

true

config.yml文件示例：

hosts: 
  - "192.168.1.85:60061"
  - "192.168.1.87:60061"
  - "192.168.1.88:60061"
# URI example
# hosts: ["mqj4zouys.us-east-1.cloud.ultipa.com:60010"]
username: "<username>"
password: "<password>"
