package main

import (
	"context"
	"fmt"
	"time"

	"github.com/cloudwego/hertz/pkg/app/client"
	"github.com/cloudwego/hertz/pkg/network/standard"
)

func main() {
	c, err := client.NewClient(
		client.WithDialTimeout(1*time.Second),
		client.WithDialer(standard.NewDialer()),
		client.WithKeepAlive(true),
	)
	if err != nil {
		return
	}

	status, body, _ := c.Get(context.Background(), nil, "http://www.example.com")
	fmt.Printf("status=%v body=%v\n", status, string(body))
}

这个例子里面用到了三个配置，第一个配置设置超时时间，默认 1 秒，第二个设置 client 使用的网络库，默认 netpoll，第三个设置是否使用长连接，默认开启。

要运行还是单文件运行然后访问请求对应的地址即可。因为这个例子里面用到的配置都和默认配置一样，所以光看结果感觉不到什么区别。
