Hi i am having very similar issue. i am trying to save the url of the input files on my database after they are uploaded to cloudinary but i can't find anyway to retrieve the url string of the uploaded files.

The cloudinary.v2.uploader.upload(" ", { }, function(error, result) ) method returns a result after the files are uploaded and i am able to access the result.url which has the url string of the uploaded file but i can not access the string outside the method even when i store it in a different variable which is created outside the scope of the method.

i have tried to print it on the console.log screen and is shows an empty string and even when i try to upload the string to the database it updates with empty string on the field. 

I have been trying to solve this problem for over two days now. Any help would go a very long way as i am stuck with my project and have checked to find a solution everywhere online. Thank you very much.

I use nodeJS on cloud 9 by the way.

  Hi Felix,

  I will recommend declaring the variable as a global variable and that way you can access it from any function.

  Here is an example:

  var ....;
  var iurl;  //global variable
  app.post('/', function (req, res){
  
  cloudinary.uploader.upload(path, function (result) {
  
  for(var attributename in result){
    if(attributename=='url'){
      iurl=result[attributename] //assigning value to iurl variable
    }
   }
  });
  
  myLogger(iurl); //calling a function outside of app.post and passing iurl value
  });
  
  var myLogger = function (reqs) {
  console.log(reqs); //printing the value
  }
