Python和Go 同时发送文件和formdata请求

# 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)

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))
}
