# Httpful
|
||||
|
||||
[![Build Status](https://secure.travis-ci.org/nategood/httpful.png?branch=master)](http://travis-ci.org/nategood/httpful)
|
||||
|
||||
[Httpful](http://phphttpclient.com) is a simple Http Client library for PHP 5.3+. There is an emphasis of readability, simplicity, and flexibility – basically provide the features and flexibility to get the job done and make those features really easy to use.
|
||||
|
||||
Features
|
||||
|
||||
- Readable HTTP Method Support (GET, PUT, POST, DELETE, HEAD, PATCH and OPTIONS)
|
||||
- Custom Headers
|
||||
- Automatic "Smart" Parsing
|
||||
- Automatic Payload Serialization
|
||||
- Basic Auth
|
||||
- Client Side Certificate Auth
|
||||
- Request "Templates"
|
||||
|
||||
# Sneak Peak
|
||||
|
||||
Here's something to whet your appetite. Search the twitter API for tweets containing "#PHP". Include a trivial header for the heck of it. Notice that the library automatically interprets the response as JSON (can override this if desired) and parses it as an array of objects.
|
||||
|
||||
$url = "http://search.twitter.com/search.json?q=" . urlencode('#PHP');
|
||||
$response = Request::get($url)
|
||||
->withXTrivialHeader('Just as a demo')
|
||||
->send();
|
||||
|
||||
foreach ($response->body->results as $tweet) {
|
||||
echo "@{$tweet->from_user} tweets \"{$tweet->text}\"\n";
|
||||
}
|
||||
|
||||
# Installation
|
||||
|
||||
## Phar
|
||||
|
||||
A [PHP Archive](http://php.net/manual/en/book.phar.php) (or .phar) file is available for [downloading](http://phphttpclient.com/httpful.phar). Simply [download](http://phphttpclient.com/httpful.phar) the .phar, drop it into your project, and include it like you would any other php file. _This method is ideal smaller projects, one off scripts, and quick API hacking_.
|
||||
|
||||
<?php
|
||||
include('httpful.phar');
|
||||
$r = \Httpful\Request::get($uri)->sendIt();
|
||||
...
|
||||
|
||||
## Composer
|
||||
|
||||
Httpful is PSR-0 compliant and can be installed using [composer](http://getcomposer.org/). Simply add `nategood/httpful` to your composer.json file. _Composer is the sane alternative to PEAR. It is excellent for managing dependancies in larger projects_.
|
||||
|
||||
{
|
||||
"require": {
|
||||
"nategood/httpful": "*"
|
||||
}
|
||||
}
|
||||
|
||||
## Install from Source
|
||||
|
||||
Because Httpful is PSR-0 compliant, you can also just clone the Httpful repository and use a PSR-0 compatible autoloader to load the library, like [Symfony's](http://symfony.com/doc/current/components/class_loader.html). Alternatively you can use the PSR-0 compliant autoloader included with the Httpful (simply `require("bootstrap.php")`).
|
||||
|
||||
# Show Me More!
|
||||
|
||||
You can checkout the [Httpful Landing Page](http://phphttpclient.com) for more info including many examples and [documentation](http:://phphttpclient.com/docs).
|
||||
|
||||
# Contributing
|
||||
|
||||
Httpful highly encourages sending in pull requests. When submitting a pull request please:
|
||||
|
||||
- All pull requests should target the `dev` branch (not `master`)
|
||||
- Make sure your code follows the [coding conventions](http://pear.php.net/manual/en/standards.php)
|
||||
- Please use soft tabs (four spaces) instead of hard tabs
|
||||
- Make sure you add appropriate test coverage for your changes
|
||||
- Run all unit tests in the test directory via `phpunit ./tests`
|
||||
- Include commenting where appropriate and add a descriptive pull request message
|
||||

# Handlers
|
||||
|
||||
Handlers are simple classes that are used to parse response bodies and serialize request payloads. All Handlers must extend the `MimeHandlerAdapter` class and implement two methods: `serialize($payload)` and `parse($response)`. Let's build a very basic Handler to register for the `text/csv` mime type.
|
||||
|
||||
<?php
|
||||
|
||||
class SimpleCsvHandler extends \Httpful\Handlers\MimeHandlerAdapter
|
||||
{
|
||||
/**
|
||||
* Takes a response body, and turns it into
|
||||
* a two dimensional array.
|
||||
*
|
||||
* @param string $body
|
||||
* @return mixed
|
||||
*/
|
||||
public function parse($body)
|
||||
{
|
||||
return str_getcsv($body);
|
||||
}
|
||||
|
||||
/**
|
||||
* Takes a two dimensional array and turns it
|
||||
* into a serialized string to include as the
|
||||
* body of a request
|
||||
*
|
||||
* @param mixed $payload
|
||||
* @return string
|
||||
*/
|
||||
public function serialize($payload)
|
||||
{
|
||||
$serialized = '';
|
||||
foreach ($payload as $line) {
|
||||
$serialized .= '"' . implode('","', $line) . '"' . "\n";
|
||||
}
|
||||
return $serialized;
|
||||
}
|
||||
}
|
||||
|
||||
|
||||
Finally, you must register this handler for a particular mime type.
|
||||
|
||||
Httpful::register('text/csv', new SimpleCsvHandler());
|
||||
|
||||
After this registering the handler in your source code, by default, any responses with a mime type of text/csv should be parsed by this handler.

How can I add a new Grant Type ?
|
||||
================================
|
||||
Simply write a new class in the namespace OAuth2\GrantType. You can place the class file under GrantType.
|
||||
Here is an example :
|
||||
|
||||
namespace OAuth2\GrantType;
|
||||
|
||||
/**
|
||||
* MyCustomGrantType Grant Type
|
||||
*/
|
||||
class MyCustomGrantType implements IGrantType
|
||||
{
|
||||
/**
|
||||
* Defines the Grant Type
|
||||
*
|
||||
* @var string Defaults to 'my_custom_grant_type'.
|
||||
*/
|
||||
const GRANT_TYPE = 'my_custom_grant_type';
|
||||
|
||||
/**
|
||||
* Adds a specific Handling of the parameters
|
||||
*
|
||||
* @return array of Specific parameters to be sent.
|
||||
* @param mixed $parameters the parameters array (passed by reference)
|
||||
*/
|
||||
public function validateParameters(&$parameters)
|
||||
{
|
||||
if (!isset($parameters['first_mandatory_parameter']))
|
||||
{
|
||||
throw new \Exception('The \'first_mandatory_parameter\' parameter must be defined for the Password grant type');
|
||||
}
|
||||
elseif (!isset($parameters['second_mandatory_parameter']))
|
||||
{
|
||||
throw new \Exception('The \'seconde_mandatory_parameter\' parameter must be defined for the Password grant type');
|
||||
}
|
||||
}
|
||||
}
|
||||
|
||||
call the OAuth client getAccessToken with the grantType you defined in the GRANT_TYPE constant, As following :
|
||||
$response = $client->getAccessToken(TOKEN_ENDPOINT, 'my_custom_grant_type', $params);

|

* require_once 'getid3/getid3.php';
|

* require_once 'getid3/getid3/extension.cache.mysql.php';
