How to handle FormData from express 4
提问by SuperUberDuper
I tried sending some form data to my node server but req.bodyhas none of my form fields the node side
我尝试将一些表单数据发送到我的节点服务器，但req.body在节点端没有我的表单字段
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
this is what I'm sending from the browser
这是我从浏览器发送的
fetch('/send', {
method: 'POST',
body: new FormData(form)
})
in dev tools I only see the data passed in the Referer, maybe that is my issue
在开发工具中，我只看到在 Referer 中传递的数据，也许这是我的问题

body-parserdoesn't handle multipart bodies, which is what FormDatais submitted as.
body-parser不处理多部分主体，这FormData是提交的内容。
Instead, use a module like multer.
相反，使用像multer.
For example, to retrieve the (regular) fields of a request:
例如，要检索请求的（常规）字段：
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);
});
