Guzzle Makes HTTP Not Hard

Guzzle is both an HTTP client and a framework for building web service clients. It gives you all the power of cURL, but is really easy to use. With a sleek, event-driven request system and the ability to make requests in parallel, Guzzle should be a permanent part of your PHP tool belt.

2. Hi, I’m Jeremy.! @jeremeamia! Seattle PHP User Group! @seaphp! AWS SDK for PHP! @awsforphp!
3. AWS SDK for PHP ! ! Built on Guzzle!!
4. Guzzle! ! Thanks to! @mtdowling! for Guzzle!! #GuzzlePHP! !
5. HTTP is Kinda Hard! •  URLs! •  Hosts! •  Headers! •  Query strings! •  GET/POST/PUT/etc.! •  Status codes! •  cURL! •  Proxies! •  Message Integrity! •  HTTPS! •  Post bodies! •  Ports! •  REST! •  Cookies! •  Hypermedia! •  Streams! •  RFCs! •  Caching!
6. Guzzle! is…!
7. …an open source PHP library!
8. …a well-crafted PHP library! •  Follows good OOP patterns and practices! •  Follows PSRs 1–4! •  Uses good tools: Composer, Travis CI, PHPUnit, GitHub, make, sphinx! •  High test coverage! •  Good documentation! •  Extensible via DI, callbacks, and events!
9. …an HTTP client! e.g., https://api.github.com!
10. …an HTTP client! $client  =  new  GuzzleHttp\Client([          'base_url'  =>  'https://api.github.com'   ]);   $response  =  $client-­‐>get('user',  [          'headers'  =>  [                  'Accept'  =>  'application/json'          ]   ]);   echo  $response-­‐>getStatusCode();   print_r($response-­‐>json());  
11. …an HTTP client! $r  =  $client-­‐>METHOD('PATH',  [PARAMS]);    
12. …an HTTP client! $r  =  $client-­‐>METHOD('PATH',  [PARAMS]);   $r  =  $client-­‐>get('PATH',  [PARAMS]);   $r  =  $client-­‐>post('PATH',  [PARAMS]);   $r  =  $client-­‐>put('PATH',  [PARAMS]);   $r  =  $client-­‐>delete('PATH',  [PARAMS]);   $r  =  $client-­‐>head('PATH',  [PARAMS]);   $r  =  $client-­‐>options('PATH',  [PARAM]);    
13. …an HTTP client! $r  =  $client-­‐>METHOD('PATH',  [          'headers'  =>  […],          'body'        =>  […],          'query'      =>  […],          'cookies'  =>  […],          'timeout'  =>  […],          'proxy'      =>  […],      //  …   ]);    
14. …an HTTP client! $r  =  $client-­‐>METHOD('PATH',  [PARAMS]);    
15. …packed with features! •  Pluggable HTTP adapters! •  Can send requests serially or in parallel! •  Doesn't require cURL, but uses it by default! •  Streams data for both uploads & downloads! •  Provides event hooks & plugins for cookies, caching, logging, OAuth, mocks, etc.! •  Keep-Alive & connection pooling! •  SSL Verification & Connection timeouts!
16. …a web service client framework! $s3  =  Aws\S3\S3Client::factory();   $result  =  $s3-­‐>listObjects([          'Bucket'  =>  $bucket   ]);   foreach  ($result['Contents']  as  $obj)  {          echo  $obj['Key'];   );  
17. …popular! •  Over 3900 stars on GitHub! •  Used in many projects including! – Drupal 8! – Goutte! – AWS SDK for PHP! – Laravel Mail Component! – Tumblr Client! – Nearly 1000 other Packagist packages!
18. And now! a story about Guzzle by! @phpbard!
19. This is a story about an elePHPant named Guzzle.! She consumes lots of data. But how? It's no puzzle.!
20. Armed with HTTP, she knows how to transport! Text and files of any size and sort.!
21. From client to server, and from server to client,! Her requests and responses are RFC compliant.!
22. And beyond the basics of just cookie and header.! There's much more to Guzzle that just makes her better:!
23. From parallel requests, from events and plugins,! To web service descriptions. And this just begins…!
24. To show you all that Guzzle can do! To help you consume your web services too.!
25. ! ! ♫ If more PHP poetry you think you can swallow,! ♫ On Twitter and Tumblr, @phpbard you should follow.!
