Question

我正在尝试在节点js express app中接收图像二进制数据。数据由以下python脚本发送：

import requests
import shutil
from time import sleep

def uploadFile(url,filename):
    url = 'http://208.97.169.108:3000'
    files = {'photo':open("C:/EmojifyMe/downloadedImage.jpg",'rb')}
    values = {'name':"Ali"}
    unsplashAuthHeader = {"auth":unsplash_id,'acceptversion': 'v1'};
    response = requests.post(url,files=files);
    print(response.text)
    if(response.status_code == 200):
        print("Upload Successful")

python脚本发出的HTTP请求是：

{
  "args": {}, 
  "data": "", 
  "files": {
    "photo": "[image binary data comes here]"
  }, 
  "form": {
    "sentby": "Osama Asif"
  }, 
  "headers": {
    "Accept": "/", 
    "Accept-Encoding": "gzip, deflate", 
    "Connection": "close", 
    "auth":"14fe25847dcac2578100192",
    "Content-Length": "273", 
    "Content-Type": "multipart/form-data; boundary=59e0880732fd417bbca2fefe900275de", 
    "Host": "httpbin.org", 
    "User-Agent": "python-requests/2.18.4"
  }, 
  "json": null, 
  "origin": "103.255.4.58", 
  "url": "http://httpbin.org/post"
}

这是我到目前为止在节点JS服务器上尝试获取属性“files.photo”时所做的：

var express = require('express');
var app = express();
var bodyParser = require('body-parser');
var urlencodedParser = bodyParser.urlencoded({ extended: false });
app.post('/', urlencodedParser, function(req, res)
{
  res.writeHead(200);
  console.log("Received");
  console.log(req.body.files.photo);
  res.end("Got it!")
});
app.listen(3000);
console.log("Listening to port 3000");

收到请求后，控制台会记录“undefined”。

我正在寻找一种方法来接收正确的二进制数据，并将其转换回jpg图像。

P.S当我尝试使用req.get（“auth”）访问“headers”的“auth”属性时，它工作正常，但此方法不适用于其他属性。

我在两端使用了base64编码，这对我来说非常合适。
