怎么从multipart/form-data获取到post参数的？ about douban_website HOT 1 CLOSED

var multer = require('multer');
var upload = multer({dest: 'public/upload/'})   //这里dest定义的是存放的目标文件夹

	var posterData = req.file    //req.file是"uploadPoster"文件信息
	console.log(posterData)       //查看posterData具体信息
	var filePath = posterData.path    
	var originalFilename = posterData.originalname //文件原始名字
	if(originalFilename){   //有文件名字，判断文件上传
		fs.readFile(filePath, function(err, data){
			var timestamp = Date.now()
			var type = posterData.mimetype.split('/')[1]
			var poster = timestamp + '.' + type
			var newPath = path.join(__dirname,'../../','/public/upload/'+poster)
			console.log('新路径为：'+newPath)
			fs.writeFile(newPath,data,function(err){
				req.poster = poster
				next()
			})
		})
	}
	else{
		next()
	}
