Python和Go 同时发送文件和formdata请求

前言

用到这个主要是做图片上传, python的好写, go的找各种文档真的挺费劲的…

Python

# 获取字节流
with open("/Users/xiaofei/Downloads/ywdhzxf.jpg", "rb") as f:
    res = f.read()
print(res)

# 发送请求
resp = requests.post(url='http://127.0.0.1/pic/upload', files={'file_stream': res},
                     data={'route_str': 'xiaofei/1d7608ac3d4bdaa28c0bdc1805f03fc2.jpg'},
                     headers={'enctype': 'mutlipart/form-data'})
print(resp.text)

Go

package main

import (
	"bytes"
	"fmt"
	"io/ioutil"
	"mime/multipart"
	"net/http"
	"os"
	"io"
)

func main() {
	var buff bytes.Buffer
	writer := multipart.NewWriter(&buff)
	// 添加form表单参数, 可以添加多个
	writer.WriteField("route_str", "xiaofei/1d7608ac3d4bdaa28c0bdc1805f03fc2.jpg")
	w, _ := writer.CreateFormFile("file_stream", "ywdhzxf.jpg")
	fd1, _ := os.Open("/Users/xiaofei/Downloads/ywdhzxf.jpg")
	defer fd1.Close()
	// 把文件流写入到缓冲区里去
	_, _ = io.Copy(w, fd1)
	writer.Close()
	//w.Write([]byte("this is a byte"))  如果有字节流直接写入就可以
	var client http.Client
	// 发送请求
	resp, err := client.Post("http://127.0.0.1/pic/upload", writer.FormDataContentType(), &buff)
	if err != nil {
		fmt.Println(err)
		return
	}
	defer resp.Body.Close()
	data, _ := ioutil.ReadAll(resp.Body)
	fmt.Println(string(data))
}
