无法读取未定义nodejs的属性“path”
这是我的服务器端代码：
var fs = require('fs'), MongoClient = require('mongodb').MongoClient, db; var url = "mongodb://localhost:27017/fullwardrobedb"; MongoClient.connect(url, {native_parser: true}, function (err, connection) { if (err) { console.log("Cannot connect to database " + url); process.exit(1); } db = connection; }); fs.exists(__dirname + '/uploads', function(exists){ if(!exists){ console.log('Creating dir ' + __dirname + '/uploads'); fs.mkdir(__dirname + '/uploads', function(err){ if(err){ console.log('Error creating dir'); process.exit(1); } }) } }); exports.addPhoto = function(req,res,next){ console.log('Starting upload file'); console.log(req.files); console.log(req.files.file); var file = req.files.file, filePath = req.files.file.path, lastIndex = filePath.lastIndexOf("/"), tmpFileName = filePath.substr(lastIndex + 1), image = req.body, images = db.collection('images'); image.fileName = tmpFileName; console.log('New file: ' + tmpFileName); images.insert(image, function (err, result) { if (err) { console.log(err); return next(err); } res.json(image); }); } 和server.js：
var express = require('express'), http = require('http'), path = require('path'), clothes = require('./routes/clothes'), users = require('./routes/users'); photos = require('./routes/photos') var app = express(); app.configure(function(){ app.use(express.logger('dev')); // app.use(express.bodyParser({ // uploadDir:__dirname + '/uploads', // keepExtensions: true // })); app.use(express.json()); app.use(express.multipart({ uploadDir:__dirname + '/uploads', keepExtensions: true })); app.use(express.static(path.join(__dirname, './uploads'))); }); app.get('/clothes', clothes.findAll); //app.get('/clothes/:id', clothes.findById); // app.post('/clothes', clothes.addWine); //app.put('/clothes/:id', clothes.updateWine); //app.delete('/clothes/:id', clothes.deleteWine); app.post('/users', users.addUser); app.get('/users', users.findAll); app.get('/users/:id', users.findById); app.put('/users/:id', users.updateUser); app.post('/photos', photos.addPhoto); app.listen(3000,'192.168.1.8'); console.log('Listening on port 3000...');
问题是，当我试图把curl image curl -i -H "Content-Type:image/jpeg" -F filedata=@antoni_01.jpg http://192.168.1.8:3000/photos
我有这样的例外：

有人可以帮助我吗？ 请注意，我是在节点JS新:)
问题是您重写了Content-Type标头。 你基本上是擦除现有的multipart/form-data Content-Type ，这是多部分中间件为了parsing表单而正在寻找的东西。 如果需要明确设置文件字段的types，可以在文件名后添加;type=image/jpeg （例如-F "filedata=@antoni_01.jpg;type=image/jpeg" ）。
另一个问题是该文件的字段名称不匹配： filedata vs file 。
