scipio v0.0.2
Scipio
A small web scraper
Scipio uses request and cheerio to retrieve pages and parse them.
License: MIT.
##Example
var Scipio = require ('scipio');
var scipio = new Scipio ();
scipio.get ('http://example.org', function ($, body) {
// $ is a jQuery selector
console.log ($ ('p').text ());
});##Usage
###.fromBody (body, callback) Get a $ selector from a body.
scipio.fromBody ('<html><body><h1>It works!</h1></body></html>', function ($) {
console.log ($ ('h1').text ());
});Callback takes ($, body) as parameters.
###.fromUrl (url, callback) Get a $ selector from a URL.
scipio.fromUrl ('http://example.org', function ($) {
console.log ($ ('p').text ());
});Callback takes ($, body) as parameters.
Alias: .get (url, callback)
###.use (function) Use a function instead of the default parser.
The parser receives (error, response, body) as parameters, and must return an array of parameters for the callback of the .fromUrl method.
The default parser returns $, body, response.
scipio.use (function (error, response, body) {
return ['foo', 'bar', 'baz', body];
});
scipio.fromUrl ('http://example.org', function (foo, bar, baz, body) {
console.log (arguments[0], arguments[1], arguments[2]);
//=> foo bar baz
});The parser function must always return an array of values as line 30 of index.js shows:
callback.apply (this, this._parser (error, body, response));###.setHeaders (key, value) Set the headers to the specified parameter.
- if the function receives two parameters, the couple
key/valuewill be added to the headers, - if the function receives only one parameter, the headers will be set to it.
scipio.setHeaders ('User-Agent', 'My Awesome UserAgent');
// => sets the headers 'User-Agent' property to 'My Awesome UserAgent'
scipio.setHeaders ({'User-Agent': 'My Awesome UserAgent'});
// => sets the headers to {'User-Agent': 'My Awesome UserAgent'}##Testing
