I got a problem with Multer, undefined req.files.path field
First, my Express.js route is:
routes.js
router.post('/', function(req, res, next){
// id, name, usersArray[], info, iconImg, headerImg
var dataObject = new MyMongooseDataObject();
// Receive data
dataObject.id = uuid.v4();
dataObject.name = req.body.name;
dataObject.usersArray = req.body.usersArray;
dataObject.info = req.body.info;
return someBindingWrapperToStoreTheFile.postFile(uuid.v4(), [req.files.iconImg.path.toString(), req.files.headerImg.path.toString()])
.then(function (postedFiles) {
dataObject.iconImg = postedFiles.body.payload.files[0].id;
dataObject.headerImg = postedFiles.body.payload.files[1].id;
//save dataObject after storing images and processing data
dataObject.save(function(savedDataObject){
next(success(req, 200, 'dataObject Saved ' + savedDataObject.id));
});
})
.catch(function(err){
console.log('FAILED: ', err.stack);
return next(failure(req, 500, err));
});
});
When I test my route with a separate small requestJS script, it works just fine:
HTTP rest api request test with requestJS
postDataObject.js
var request = require('request');
var fs = require('fs');
var uuid = require('uuid');
var formData = {
name: 'someName',
info: 'Some INFO and text description. ',
'usersArray[0][uuid]': uuid.v4().toString(),
'usersArray[1][uuid]': uuid.v4().toString(),
'usersArray[2][uuid]': uuid.v4().toString(),
// handle files
iconImg: fs.createReadStream('/var/tmp/img/iconImg.png'),
headerImg: fs.createReadStream('/var/tmp/img/headerImg.png')
};
request.post({url:'http://127.0.0.1:2233/api/postDataObject', formData: formData}, function (err, httpResponse, body) {
if (err) {
return console.error('failed:', err);
}
console.log('DataObject creation is successful! Server responded with:', body);
});
Now I'm writing the wrapper library for the fronted usage, when I use the same code in another context, it seems, that Multer handling req.files.headerImg.path is not working, it's undefined.
The code I use for wrapper library:
wrapper-lib.js
var request = require('request'),
URI = require('URIjs'),
fs = require('fs'),
uuid = require('uuid'),
path = require('path'),
Promise = require('bluebird'),
_ = require('lodash'),
DataObjectBindings.prototype.createDataObject = function (jsonRequestJSFormData) {
var self = this;
// this give the URL of the API to make requests to
return self.getAPIurlHelper().then(function (apiUrl) {
return new Promise(function (resolve, reject) {
request.post({url: apiUrl, form: jsonRequestJSFormData}, function (err, res, body) {
if (err) {
reject(err);
} else {
resolve({res: res, body: JSON.parse(body)});
};
}); //end of .post
}); // end of Promise
}); // end of getAPIurlHelper() function
}; // end of createDataObject function definition
And Finally I test the warpper with:
wrapper-test.js
// Instantiate Broker Client
var Wrapper = require('./wrapper-lib');
var wi; //wrapper instalnce
var ConnectApiRequestTracer = require('./connectApiRequestTracer');
var fs = require('fs');
ConnectApiRequestTracer().connect()
.then(function () {
wi = new Wrapper();
return wi.createDataObject(
uuid.v4(),
{
name: 'Some Cool Name',
info: 'Some nice description and info. ',
'usersArray[0][uuid]': uuid.v4().toString(),
'usersArray[1][uuid]': uuid.v4().toString(),
'usersArray[2][uuid]': uuid.v4().toString(),
iconImg: fs.createReadStream('/var/tmp/img/iconImg.png'),
headerImg: fs.createReadStream('/var/tmp/img/headerImg.png'),
);
})
.then(function (data) {
console.log('SUCCESS: ', data);
})
.catch(function (err) {
console.log('FAILED', err.stack);
});
When I run the test case wrapper-test.js, it throws me an error, that says the req.files.iconImg.path is undefined.
Any ideas what can be wrong?
