javascript - require filename while downloading file using request module nodejs -

I use the request module in nodes to download the file (image file only) using this I'm doing,

  request ('http://google.com/doodle.png'). Pipe (fs.createWriteStream ('doodle.png')),   
 or  
  request (url) .pipe (fs.createWriteStream (filename)) ,   
 But I only have url available and I need it to protect the file from its real name, so I must get the file name from the given url,  
  Please suggest to me how the last part of the URL has been removed   
 Thank you in advance ...   
 
 
 A simple solution can be:  
  var path = required ('path'); Var FS = Requirement ('FS'); // ... var filename = path.basename (url); Request (url) .pipe (fs.createWriteStream (file name));
