Node.js Multiparty-Upload funktioniert nicht

Question

Die multiparty.Form() funktioniert nicht. Ich versuche zu drucken. (Zum Beispiel 2,3,4)

Hier ist mein Bild-Upload-Code:

app.post('/gallery/add',function(req, res,next) { 
var input = JSON.parse(JSON.stringify(req.body)); 
var multipart = require('connect-multiparty'); 
var multiparty = require('multiparty'); 
var format = require('util').format; 
var fs = require("fs"); 
var path = require('path'); 
var tempPath =req.files.image.path; 
var filename2 =req.files.image.originalFilename; 
req.getConnection(function (err, connection) { 
    console.log('1'); 
    var form = new multiparty.Form(); 
    var image; 
    var title; 
form.on('error', next); 
    form.on('close', function(err, fields, files){ 
     console.log('2'); 
     if(err) { 
     next(err); 
     console.log(err); 
    } else { 
    console.log('3'); 
     ins = fs.createReadStream(tempPath); 
     ous = fs.createWriteStream(__dirname + '/uploads/' + image.filename); 
     util.pump(ins, ous, function(err) { 
     if(err) { 
      next(err); 
     } else { 
      res.redirect('/#gallery/add'); 
      res.end(); 
     } 
     }); 
     //console.log('\nUploaded %s to %s', files.photo.filename, files.photo.path); 
     //res.send('Uploaded ' + files.photo.filename + ' to ' + files.photo.path); 
    } 
    res.send(format('\nuploaded %s (%d Kb) as %s' 
     , image.filename 
     , image.size/1024 | 0 
     , title)); 
    }); 
// listen on field event for title 
    form.on('field', function(name, val){ 

    console.log('4'); 
    if (name !== 'title') return; 
    title = val; 
    }); 

    // listen on part event for image file 
    form.on('part', function(part){ 
console.log('5'); 
    if (!part.filename) return; 
    if (part.name !== 'image') return part.resume(); 
    image = {}; 
    image.filename = part.filename; 
    image.size = 0; 
    part.on('data', function(buf){ 
     image.size += buf.length; 
    }); 
    }); 

    // parse the form 
    form.parse(req); 

    }); 
}); 

Es scheint, wie die form.on Methode funktioniert nicht.

Wohin gehe ich falsch?

Answer 1

es einfach verwenden:

// parse a file upload 
    var form = new multiparty.Form(); 

    form.parse(req, function(err, fields, files) { 
     res.writeHead(200, {'content-type': 'text/plain'}); 
     res.write('received upload:\n\n'); 
     res.end(util.inspect({fields: fields, files: files})); 
    }); 

    return;
