未定义busboy与expres的connect-busboy

Question

I am working with expressjs 4.12.3, and trying to connect to connect-busboy, but on request I am not able to get req.busboy object, it says "undefined" my simple code is as follows :

 var express=require('express'); var busboy = require('connect-busboy'); var app=express(); app.use(busboy()); app.use(function(req, res, next) { req.busboy.on('field', function(fieldname, val) { // console.log(fieldname, val); req.body[fieldname] = val; }); req.busboy.on('finish', function(){ next(); }); }); app.listen(5555); 

I have initialize busboy module, assigned it to the app, also sending content-length: "5276" content-type:'application/x-www-formurlencoded' as headers.

what am I doing wrong??

Answer 1

The problem is that you're setting up event handlers, but you're not actually piping the request to busboy so it can parse the request. Add req.pipe(req.busboy); after your busboy event handlers and it should work fine.

EDIT: I slightly misread your question. If req.busboy is undefined that means the Content-Type is wrong. If your Content-Type really is application/x-www-formurlencoded , then that is wrong. It should be: application/x-www-form-urlencoded .
