Hertz 学习笔记（25）

使用 hertz 客户端上传文件的示例

这一个例子也是配合服务端的例子来使用的，客户端的代码如下：

package main

import (
	"context"
	"fmt"

	"github.com/cloudwego/hertz/pkg/app/client"
	"github.com/cloudwego/hertz/pkg/protocol"
	"github.com/cloudwego/hertz/pkg/protocol/consts"
)

func main() {
	client, err := client.NewClient()
	if err != nil {
		return
	}
	req := &protocol.Request{}
	res := &protocol.Response{}
	req.SetMethod(consts.MethodPost)
	req.SetRequestURI("http://127.0.0.1:8080/singleFile")
	req.SetFile("file", "./client/upload_file/file1.txt")

	err = client.Do(context.Background(), req, res)
	if err != nil {
		return
	}
	fmt.Println(err, string(res.Body()))

	req.SetRequestURI("http://127.0.0.1:8080/multiFile")
	req.SetFile("file", "./client/upload_file/file2.txt")
	err = client.Do(context.Background(), req, res)
	if err != nil {
		return
	}
	fmt.Println(err, string(res.Body()))
}

然后同一目录里放两个 txt 文件即可，这里用到的 Do() 方法就是刚刚学到的客户端发送请求的一种写法。最后分别打印两个请求的响应。
