我想在工作区中上传文件，并在node.js中阅读。
Html代码：
<html>
<head>
<script src = "http://ajax.googleapis.com/ajax/libs/angularjs/1.3.14/angular.min.js"></script>
</head>
<body>
<div ng-app="" ng-controller="SalesImportControl">
<form ng-submit="readCustomer()">
<input type="file" name="file" file-model = "myFile">
<br>
<button type="submit" >Submit</button>
</form>
</div>
</body>
</html>
控制器：
'use strict';
angular.module('app')
.controller('SalesImportControl', ['$scope','$http', '$location', '$rootScope','fileUpload' , function($scope, $http, $location, $rootScope,fileUpload) {
console.log(" In dataimportCtrl");
//customer
$scope.readCustomer = function(req,res){
var file1=$scope.myFile;
var fl1 = $scope.myFile.name;
console.log("file name:"+$scope.myFile.name);
var uploadUrl = "/fileUpload";
var fd = new FormData();
fd.append('file', file1);
//File upload
$http.post(uploadUrl, fd, {
transformRequest: angular.identity,
headers: {'Content-Type': undefined}
}).success(function(data){
}).error(function(){
});
//sales
$http.post('/salesimport', { params: fl1 }).success(function(data) {
console.log("in controller1");
console.log("controller:"+data);
$scope.data=data["jarr"];
$scope.data1=data["jarr1"];
$scope.data2=data["jarr2"];
$scope.data3=data["jarr3"];
$scope.data4=data["jarr4"];
}).error(function(response) {
console.error("error in posting");
});
};
}])
Server.js：
var express = require('express');
var bodyparser = require('body-parser');
var mysql = require('mysql');
var app = express();
var formidable = require('formidable');
var path = require('path');
var fs = require('fs');
var _ = require('underscore');
var vouchersmodel = require('./models/v_db.js');
app.use(express.static(__dirname + "/public/angular"));
app.use(bodyparser.json());
app.listen(3000);
console.log('Server running on 3000');
app.post('/fileUpload', function (req, res) {
var form = new formidable.IncomingForm();
//Formidable uploads to operating systems tmp dir by default
form.uploadDir = __dirname+"/models/upload2/"; //set upload directory
form.keepExtensions = true; //keep file extension
form.parse(req, function(err, fields, files) {
res.writeHead(200, {'content-type': 'text/xml'});
res.write('received upload:\n\n');
console.log("form.bytesReceived");
console.log("file size: "+JSON.stringify(files.file.size));
console.log("file path: "+JSON.stringify(files.file.path));
console.log("file name: "+JSON.stringify(files.file.name));
console.log("file type: "+JSON.stringify(files.file.type));
console.log("astModifiedDate:"+JSON.stringify(files.file.lastModifiedDate));
console.log("file:"+JSON.stringify(files.file));
vouchersmodel.upload(files.file.path,files.file.name, function (msg) {
return res.json(msg);
});
});
});
型号：
exports.upload= function(r,name,callback){
var fs = require('fs');
var newPath = __dirname + "/upload2/"+name;
fs.readFile(r, function (err, data) {
fs.writeFile(newPath,data, function (err,res) {
if(!err){
console.log("uploaded.........");
callback();
}
});
});
}
我的问题是它上传文件但在上传文件之前它在控制器中运行salesimport post方法并且没有显示这样的目录错误。 哪里错了？
注意： salesimport post方法请求访问模型中上传的文件。
