我在express3.x上并且使用强大

app.post "/up",(req,res)->
formidable = require('formidable')
form = new formidable.IncomingForm()
form.uploadDir = __dirname + "/uploads"
form.encoding = 'binary'


form.addListener 'file',(name,file) ->
    #write file
    console.log('file uploaded')
    return
console.log('$$$$$$$$$$$')
form.addListener 'end', ->
    console.log('end')
    res.end()
    return
console.log('@@@@@$$$$')
form.parse req,(err,fields,files)->
    console.log('parse')
    console.log(err) if(err)
    return
console.log('######')
return

上载表格是
block content
:coffeescript
    $ ->
        formData = new FormData()
        xhr = new XMLHttpRequest()
        onProgress = (e)->
            per_complete = (e.loaded/e.total) * 100 if e.lengthComputable

        onReady = (e)->
            alert("Ready")

        onError = (err)->
            alert("Error Loading "+err)

        $('#upload').click (e)->
            formData.append('img',document.getElementById('img').files[0])
            xhr.open('post','/up',true)
            xhr.addEventListener('error',onError,false)
            xhr.addEventListener('progress',onProgress,false)
            xhr.send(formData)
            xhr.addEventListener('readystatechange',onReady,false)

h1 hello world
form
    |select Image:
    input(type='file',name='img', id='img')
    input(type='button',value='button', id='upload')

没有任何事件被触发...不确定我想念的是什么..

最佳答案

如果您使用app.use(express.bodyParser())等效于:

app.use(express.json());
app.use(express.urlencoded());
app.use(express.multipart());

您可以删除app.use(express.multipart());,然后可以使用强大的对象。
