Nodejs Express Frame Upload file

Web Project Application express4.0 Framework

HTML form Post File upload failed, backend cannot get submit file

Express does not support file uploads.

Way One

If the picture, you can transcode the image to BASE64 upload

The front-end framework Angularjs code Conversion code is as follows

$scope. filechange=function(index) {varFile = This. files[0]; varURL =webkiturl.createobjecturl (file); /*Create picture *----------------------*/        var$img =NewImage (); $img. SRC=URL; $img. OnLoad=function () {            //Build Scale            varwidth = This. width, height= This. Height, scale= width/height; Width= parseint (800); Height= parseint (Width/Scale ); //Build Canvas            var$canvas = $ (' #canvas '); varCTX = $canvas [0].getcontext (' 2d '));            $canvas. attr ({width:width, height:height}); Ctx.drawimage ($img,0, 0, width, height); varBase64 = $canvas [0].todataurl (' Image/jpeg ', 0.5); varCC = $ ("#pic" +index); Cc.attr ("SRC", URL); postdata["File" + index] = base64.substr (23); }} $scope. Upload=function() {$http. Post (' Uploadfile/fenxiangimg?wxopenid=222&orderid=111&templateid=1 ', $scope. postdata). Success (function(data) {alert ("Sucess");    }); }

Way Two

Nodejs back-end reference Connect-multiparty package

The back-end code is as follows

Routing

var multipart = require (' Connect-multiparty ');     var multipartmiddleware = multipart ();    App.post (function(req, res) {        if(req.session&&  Req.session.account) {            var filepath=Req.files.peoples.path;            Console.log (req);            People.insertpeoples (Req,res,filepath);        }         Else {            res.send ({error:1})        }    );

Business logic Implementation

functionInsertpeoples (Req,res,filepath) {basemodule.checkaccountrole (req,res,function(account) {Fs.readfile (filepath,function(Err, filedata) {Console.log (Err+filedata); Csv.parse (Filedata, {comment:‘#‘},function(err, Output) {Fs.unlink (filepath,function(Err) {}); varallpeoples=[]; varkeys=[' _id ', ' idcard ', ' wechatuid ', ' qqnum ', ' mac ', ' name '];                Console.log (json.stringify (output)); Output.foreach (function(people) {varpeopleobj={};  for(varI =0;i<keys.length;i++) {Peopleobj[keys[i]]=People[i]; }                    if(Peopleobj.mac) {Peopleobj.mac=peopleobj.mac.toUpperCase ();                } allpeoples.push (Peopleobj);                }); if(allpeoples.length>0) {db.insertpeoples (Allpeoples,account,function(err,doc) {if(!err) {Res.redirect ('/#people '); }Else{Res.send ({error:1})}                    })                }                Else{res.redirect ('/#people ');        }            });    }); })}
