如何处理来自 express 4 的 FormData [英] How to handle FormData from express 4

问题描述

我尝试向我的节点服务器发送一些表单数据，但是 req.body 在节点端没有我的表单字段

I tried sending some form data to my node server but req.body has none of my form fields the node side

 var express = require('express')
var app = express()
var path = require('path')
var bodyParser = require('body-parser')
app.use(bodyParser.urlencoded({
  extended: true
}));

app.get('/', function (req, res) {
  res.sendFile('index.html')
})
app.post('/sendmail', function (req, res) {

  const formData = req.body.formData

这是我从浏览器发送的内容

this is what I'm sending from the browser

fetch('/send', {
  method: 'POST',
  body: new FormData(form)
})

在开发工具中，我只能看到在 Referer 中传递的数据，这可能是我的问题

in dev tools I only see the data passed in the Referer, maybe that is my issue

Referer:http://localhost:3000/?name=&budget=%C2%A31000

推荐答案

body-parser 不处理多部分主体，这就是 FormData 提交的内容.

body-parser doesn't handle multipart bodies, which is what FormData is submitted as.

相反，使用像 multer 这样的模块.

Instead, use a module like multer.

例如，检索请求的(常规)字段:

For example, to retrieve the (regular) fields of a request:

const multer = require('multer');
const upload = multer();

app.post('/send', upload.none(), (req, res) => {
  const formData = req.body;
  console.log('form data', formData);
  res.sendStatus(200);
});
