Uploading a file through JS API

Hi,I'm trying to use the https://www.npmjs.com/package/alfresco-js-api to build an application (Node) aiming to create files in Alfresco.I have a Community Edition Alfresco installed.let AlfrescoApi = require('alfresco-js-api');let alfrescoJsApi = new AlfrescoApi();let fs = require('fs');alfrescoJs

Well, by looking at the sample code in the project's page, I noticed that all the upload content samples have more parameters besides the content itself.

Samples below got from alfresco-js-api :

this.alfrescoJsApi.upload.uploadFile(fileToUpload, null, null, null, {autoRename: true})
this.alfrescoJsApi.upload.uploadFile(fileToUpload, 'folderX/folderY/folderZ')

var parentFolder = '80a94ac8-3ece-47ad-864e-5d939424c47c';
this.alfrescoJsApi.upload.uploadFile(fileToUpload, 'folderX/folderY/folderZ', parentFolder )‍‍‍‍‍

So, for me, it seems the problem is that you are not providing all the required parameters, and because of that, Alfresco is complaining about the message "Required parameters are missing"

Sadly, I tried all these methods, and none of them had a different effect.

EDIT: Looking at the variable 'bodyParam' in the class 'alfrescoApiClient.js' it returned this :

{ name: undefined,
nodeType: 'cm:content',
relativePath: 'Sites/test-site/documentLibrary' }

So I added

fileToUpload.name = 'testFile.txt'

And then, in the 'alfrescoApiClient.js' I got

{ name: 'testFile.txt',
nodeType: 'cm:content',
relativePath: 'Sites/test-site/documentLibrary' }

But still this error ...

Looking the documentation showed me that your file should be uploaded to alfrescos root directory if you use only the filestream parameter. But you should try like Douglas C. R. Paes proposed.

But I think it wouldn't be working at all, because your login call will return a promise immediately. You are not logged in at this moment.

Try to move your upload function into the success conditon (after your console.log for example) of your login function.

PS: The missing parameter could be the login ticket, that's not defined in the moment of your upload

So, I've put the uploading stuff after the login, added a .name to the Stream, tried every methods proposed before but .... still got this error ...

I really don't understand where it comes from 😕

fileToUpload Is ok, not null? Meaning, can you read it with fileToUpload.read() and log it's contents to the console?

Re: Uploading a file through JS API

alexandreb — Thu, 01 Jun 2017 08:41:43 GMT

Well,
console.log(fileToUpload) does display content

but

console.log(fileToUpload.read()) returns null

Re: Uploading a file through JS API

mehe — Thu, 01 Jun 2017 09:09:43 GMT

...you would have to put ...read() in fileToUpload.on('readable'....

but if console.log(fileToUpload) shows content, your Stream/file is ok.

Re: Uploading a file through JS API

alexandreb — Thu, 01 Jun 2017 09:13:45 GMT

Yep, I tried to put the upload in events emitted from the readStream but doesn't work either.
And yes .read() worked in 'readable'

I'v also tried directly with

curl -uadmin:admin -X POST localhost:8080/alfresco/api/-default-/public/alfresco/versions/1/nodes/-root-/children -F diledata=@testFile.txt

But as usual ... this error ...

I even tried this :

var http = require("http");

   var options = {
      'host': 'localhost',
      'port': '8080',
      'path': '/alfresco/service/api/login',
      'method': 'POST',
      'content-type': 'application/json',
   };

   var body = {
       'username': 'admin',
       'password': 'admin'
   }

   var req = http.request(options, function(res) {
      console.log('STATUS: ' + res.statusCode);
      console.log('HEADERS: ' + JSON.stringify(res.headers));
      res.setEncoding('utf8');
      res.on('data', function (chunk) {
        console.log('BODY: ' + chunk);

       options.path = 'alfresco/api/-default-/public/alfresco/versions/1/nodes/-root-/children'

       var req2 = http.request(options, function(res) {
          console.log('STATUS: ' + res.statusCode);
          console.log('HEADERS: ' + JSON.stringify(res.headers));
          res.setEncoding('utf8');
          res.on('data', function (chunk) {
            console.log('BODY: ' + chunk);
          });
       });

       var body = {
           "name":"My folder",
           "nodeType":"cm:folder",
           "relativePath": 'Sites/test-site/documentLibrary'
       }

       // write data to request body
       req2.write(JSON.stringify(body));
       req2.end();

      });
   });

   req.on('error', function(e) {
      console.log('problem with request: ' + e.message);
   });

   // write data to request body
   req.write(JSON.stringify(body));
   req.end();

Connection returns status 200 ... but uploading returns 400 with no message ...

...hmmm, your alfresco and alfresco-js-api version is?

Re: Uploading a file through JS API

alexandreb — Thu, 01 Jun 2017 14:27:39 GMT

Alfresco Community v5.2.0

"alfresco-js-api": "^1.5.0"

Re: Uploading a file through JS API

alexandreb — Fri, 02 Jun 2017 08:38:47 GMT

Okay, I managed to create a file using REST, doing few changes :

In var options :

'headers': {
'Content-Type': 'application/json'
}

Also, the path to upload :

options.path = '/alfresco/api/-default-/public/alfresco/versions/1/nodes/-root-/children?alf_ticket='+JSON.parse(chunk).data.ticket

But I still don't know how to upload an existing file

Re: Uploading a file through JS API

alexandreb — Fri, 02 Jun 2017 12:50:07 GMT

Okay so I figured out how to upload a File, once logged and var ticket initialized :

var request = require('request')
var fs = require('fs')
var r = request.post('http://localhost:8080/alfresco/api/-default-/public/alfresco/versions/1/nodes/-root-/children?alf_ticket='+ticket, function callback(err, httpResponse, body) {
           if(err || JSON.parse(body).error) {
               return console.log('Upload failed : ' + body)
           }
           console.log('Upload success')
       })
var form = r.form()
form.append("name", "testFile.txt")
form.append("nodeType", "cm:content")
form.append("relativePath", "Sites/test-site/documentLibrary")
form.append("filedata",fs.createReadStream('./testFile.txt'))

I don't use alfresco-js-api anymore

Re: Uploading a file through JS API

Hi Alexandre,

sorry I had no time to answer - I'm using alfresco-js-api with angularJS clients but didn't use the upload function until now (migrating from old stuff, upload is still the old code).

I had some login issues with alfresco-js-api, but after asking under the adf section of alfresco community, my problems were solved in no time.

If you are interested, I will share my experience when using (or trying to use) the upload-function - but this won't be before July.

It would be helpful if you could share your experience in July.
