在Node.js + Express（通过多方）上传表格
这是我在app / routes / index.js中的上传方法：
exports.uploadFile = function(req, res) { var multiparty = require('multiparty'); var gm = require('gm'); var fs = require('fs'); var form = new multiparty.Form(); var size = ''; var fileName = ''; form.on('part', function(part){ if(!part.filename) return; size = part.byteCount; fileName = part.filename; }); form.on('file', function(name,file){ console.log(file.path); console.log(__dirname); console.log('filename: ' + fileName); console.log('fileSize: '+ (size / 1024)); var tmp_path = file.path var target_path = __dirname + '/uploads/fullsize/' + fileName; var thumbPath = __dirname + '/uploads/thumbs/'; fs.renameSync(tmp_path, target_path, function(err) { if(err) console.error(err.stack); }); res.redirect('/uploads/fullsize/' + fileName); console.log(target_path); /*gm(tmp_path) .resize(150, 150) .noProfile() .write(thumbPath + 'small.png', function(err) { if(err) console.error(err.stack); });*/ }); form.parse(req); };
我从app.js中调用这个方法
app.post('/uploadFile', routes.uploadFile);
当我从上传表单上传文件时，在控制台中得到这个错误信息：
/tmp/9039-1m6kw46.jpg /home/danyaloff/Development/nodejs/projects/nodetest1/routes filename: 3D-Background-Wallpapers-HD-Wallpapers-in-HD.jpg fileSize: 910.255859375 fs.js:543 return binding.rename(pathModule._makeLong(oldPath), ^ Error: ENOENT, no such file or directory '/tmp/9039-1m6kw46.jpg' at Object.fs.renameSync (fs.js:543:18) at Form.<anonymous> (/home/danyaloff/Development/nodejs/projects/nodetest1/routes/index.js:25:6) at Form.EventEmitter.emit (events.js:98:17) at WriteStream.<anonymous> (/home/danyaloff/Development/nodejs/projects/nodetest1/node_modules/multiparty/index.js:527:10) at WriteStream.EventEmitter.emit (events.js:117:20) at fs.js:1596:14 at Object.oncomplete (fs.js:107:15) 23 Dec 03:52:59 - [nodemon] app crashed - waiting for file changes before starting...
但是当我在我的app.js文件中使用上传function：
app.post('/uploadFile', function(req, res){ //my upload function });
一切正常。 我的代码中有什么问题？ 谢谢！
使用后问题解决了：
var target_path = './uploads/fullsize/' + fileName;
代替
var target_path = __dirname + '/uploads/fullsize/' + fileName;
