主要用到了formidable模塊：
/** * [導出一個中間件，formupload，用於處理文件上傳；] */ exports.formupload = function(req,res,next){ //console.log(req); var form = new formidable.IncomingForm(); var uploadDir = path.normalize(__dirname+'/'+"../avatar"); form.uploadDir = uploadDir; console.log(uploadDir); form.parse(req, function(err, fields, files) { for(item in files){ (function(){ var oldname = files[item].path; var newname = files[item].name === 'blob' ? oldname+'.xml' : oldname+"."+files[item].name.split('.')[1]; fs.rename(oldname,newname,function(err){ if(err) console.log(err); console.log('修改成功'); }) })(item); } console.log(util.inspect({fields: fields, files: files})); res.send('2'); });
