在POST中将文件和数据从Python上传到Node.js中

Question

如何将文件发送到POST中的Node.js和参数数据。我很高兴使用任何框架。我曾经尝试过，但我很乐意改变。

在我的尝试中，文件发送，但req.body是空

Python代码上传：

with open('fileName.txt', 'rb') as f: 
     payLoad = dict() 
     payLoad["data"] = "my_data" 
     r = requests.post('http://xx.xx.xx.xx:8080/sendFile',json = payLoad, files={'fileName.txt': f}) 

服务器端的Node.js：

var express = require('express'); 
var formidable = require('formidable'); 
var app = express(); 
var bodyParser = require('body-parser'); 

app.use(bodyParser.json()); 
app.use(bodyParser.urlencoded({ extended: false })); 

app.post('/sendFile', function (req, res){ 
    console.log(req.body) 
    // req.body is empty

我不t知道如何正确使用python发送文件，但要接收带有node.js的文件，您可以使用express-fileupload

var fileUpload = require('express-fileupload'); 
app.use(fileUpload()); 

app.post('/upload', function(req, res) { 
    if (!req.files) 
    return res.status(400).send('No files were uploaded.'); 

    // The name of the input field (i.e. "sampleFile") is used to retrieve the uploaded file 
    let sampleFile = req.files.sampleFile; 

    // Use the mv() method to place the file somewhere on your server 
    sampleFile.mv('/somewhere/on/your/server/filename.jpg', function(err) { 
    if (err) 
     return res.status(500).send(err); 

    res.send('File uploaded!'); 
    }); 
});
