Using the cURL module

Previous: Using Getopt

Flusspferd provides an interface for libcurl. libcurl is a very extensive data transfer library. It supports HTTP(s), FTP, SSH and several other protocols with different authentication mechanisms and it is quite popular.

Flusspferd's cURL module is very similar to the interface of libcurl and people familiar with using libcurl in other languages should feel right at home. But names are converted into Javascript style and some functions and options were omitted or hidden (see implementation notes).

Using the cURL module is straight forward

 const cURL = require('curl');

 var c = new cURL.Easy();
 c.options.url = 'http://www.google.com';
 c.perform();

This should print the html data from google.com. Of course you usually do not want to print the data. You can add a callback to handle the retrieved data

 var buffer;
 c.options.writefunction = function(data,size) {
   buffer = data.decodeToString();
   return data.length; // return data.length if everything is ok.
 }
 c.options.url = 'http://www.google.com';
 c.perform();

 // do something with buffer
 print("Got this: " + buffer);

cURL provides a lot of options and you can fine tune your requests. See cURL.Easy::options for more.
