PSR-7 is imminent, and here's my issues with it.
March 04, 2015 @ 09:26:37

Evert Pot has written up a new post today with some of his thoughts about what's wrong with the PSR-7 proposal in the PHP-FIG. PSR-7 relates to a standardized interface for HTTP request and response handling.

PSR-7 is pretty close to completion. PSR-7 is a new 'PHP standard recommendation', put out by the PHP-FIG group, of which I'm a member of. [...] PSR-7 gets a lot of things right, and is very close to nailing the abstract data model behind HTTP, better than many other implementations in many programming languages.

But it's not perfect. I've been pretty vocal about a few issues I have with the approach. Most of this has fallen on deaf ears. I accept that I might be a minority in feeling these are problems, but I feel compelled to share my issues here anyway. Perhaps as a last attempt to sollicit change, or maybe just to get it off my chest.

He breaks up his thoughts into a few different categories, each with a summary and sometimes some code to help make his point a bit more clear. He talks about immutability, how objects will be immutable and shows an example of change in how Silex would have to function to follow the standard (with before/after). He then goes on to talk about the "issue with streams" and how the current proposal could allow for changing of the incoming request into a new one with new headers...not immutable. He ends the post talking about PSR-7's stance on buffering responses and how, even if his project doesn't adopt the PSR in the strictest sense, they may still take some inspiration from it.

Matthew Weier O'Phinney:
PSR-7 By Example
January 29, 2015 @ 09:13:20

As a part of his involvement in the PHP-FIG standards group, Matthew Weier O'Phinney has been contributing to the PSR-7 proposal. This proposal defines a standardized structure for HTTP message handling. In his latest post he gets into a bit more detail on what this means for the PHP developer and how it might be implemented.

PSR-7 is shaping up nicely. I pushed some updates earlier this week, and we tagged 0.6.0 of the http-message package last week for implementors and potential users to start coding against. I'm still hearing some grumbles both of "simplify!" and "not far enough!" so I'm writing this posts to demonstrate usage of the currently published interfaces, and to illustrate both the ease of use and the completeness and robustness they offer.

He starts with a base definition of what the proposal, well, proposes around HTTP messaging, both the incoming and outgoing. He describes the basic structure of an HTTP message and what each part represents. He talks about message headers, bodies and how the current library could return that content. He then looks at requests vs responses, server-side requests and some various uses cases and more practical examples:

  • HTTP Clients
  • Middleware
  • Frameworks

With the PSR-7 standard in place, all of these different tools could have interchangeable interfaces for HTTP request/responses, easily swappable with any other implementation.

Dave Hulbert:
Thoughts on PSR-7
January 12, 2015 @ 12:51:03

In a new post to his site Dave Hulbert has shared some of his thoughts about the PSR-7 standard, a HTTP proposal for HTTP handling.

PSR-7 contains interfaces for HTTP messages. These are like Symfony Kernel's Request and Response interfaces. Having these new interfaces would be great for the PHP community but there's a couple of issues with their current state that I'm not happy with.

One of PSR-7's goals is "Keep the interfaces as minimal as possible". I think the current interfaces are not minimal enough.

He breaks down his thoughts into a few different sections covering ideas around:

  • Immutability and PSR-7's enforcement of mutability
  • Being too strict to the (HTTP) spec
  • Splitting client and server message interfaces
  • Writing and reading from StreamableInterface

He sums up his thoughts under each section pretty quickly. If you haven't heard much about the PSR-7 proposal and want more context on what he's referencing, check out this proposal (or other posts sharing opinions from other developers).

Matthew Weier O'Phinney:
On HTTP, Middleware, and PSR-7
January 09, 2015 @ 11:38:17

Matthew Weier O'Phinney has a new post to his site today with a thought about how to make the Zend Framework (both ZF1 & ZF2) easier for developers to get into and use. He suggests that middleware might be the answer.

As I've surveyed the successes and failures of ZF1 and ZF2, I've started considering how we can address usability: how do we make the framework more approachable? One concept I've been researching a ton lately is middleware. Middleware exists in a mature form in Ruby (via Rack), Python (via WSGI), and Node (via Connect / ExpressJS); just about every language has some exemplar. Even PHP has some examples already, in StackPHP and Slim Framework.

[...] The idea is that objects, hashes, or structs representing the HTTP request and HTTP response are passed to a callable, which does something with them. You compose these in a number of ways to build an application.

He gives some examples of current frameworks and libraries that make use of the middleware idea, showing both object and callable methods. He points out that, while middleware is approachable and makes a developer's life easier, it's not something PHP can internally handle. He covers the things a PHP developer would need to access just to get the complete details about a HTTP request and that what's really needed is good HTTP abstraction handling, something the PHP-FIG group has been working on as a part of PSR-7. He includes some examples of how it might be used and where middleware would fit into the picture.

Too often, I feel as PHP developers we focus on the tools we use, and forget that we're working in an HTTP-centric ecosystem. [...] If PSR-7 is ratified, I think we have a strong foot forward towards building framework-agnostic web-focused components that have real re-use capabilities -- not just re-use within our chosen framework fiefdoms.

Michael Dowling:
Guzzle 5 and RingPHP
October 14, 2014 @ 10:52:25

Michael Dowling has a new post to his site today talking about the latest release for the Guzzle HTTP library and how it now works with RingPHP to make integration life easier. The RingPHP library, inspired by Clojure's Ring library, provides a low-level structure to work with HTTP clients and servers through a simple interface.

With RingPHP, Guzzle does not require cURL and can be used with any HTTP transport mechanism. I'd love to help anyone who is interested in creating RingPHP adapters to bind Guzzle to another library. For example, WyriHaximus on Github is working on binding Guzzle to ReactPHP. (In fact, Guzzle 4 did not require cURL, though it was much harder to use an alternate transport.)

He goes on to talk more about the changes in the Guzzle 5 release including more detail on the RingPHP integration, the use of promises/futures and iterable and callable streams. There's also several new events included in the release as well. He finishes out the post with an upgrade guide to help make the transition easier.

Michael Dowling:
Guzzle-Ring and Future Responses
September 30, 2014 @ 09:36:32

Michael Dowling has a new post to his site today talking about the work that's being done on the upcoming release of the Guzzle HTTP client. In the post he talks about a major change in how it allows for asynchronous requests and the work on Guzzle-Ring to make it happen.

Guzzle 4 has been out for a little over six months. It has proven to be leaps and bounds better than Guzzle 3, and I've been very happy with the design so far. However, after the release of Guzzle 4, I've received feedback from numerous members of the PHP community that can be boiled down to "Guzzle needs async support." While Guzzle has always had the ability to send requests concurrently using a pool of requests, there was not a way to send asynchronous requests.

After a couple months of work and borrowing concepts from Clojure, I've created Guzzle-Ring, an extremely simple adapter and middleware library for PHP (not just Guzzle) that can power both clients and servers for both synchronous and asynchronous requests.

The Guzzle-Ring reduces the need for the previous complexity of creating multiple adapters, which ended up with the adapters knowing too much about the request itself. He introduces the Guzzle-Ring system that will be included in Guzzle v5, heavily influenced by Clojure. The adapter makes the request as simple as passing in an array and makes use of "futures" to handle the request/response cycle. He also talks some about creating middleware piece that helps integrate it into your application, wrapping functionality inside of another method. He illustrates all of this with code examples and includes others such as fetching of future responses, sending requests concurrently and the Guzzle-Ring server adapters.

SitePoint PHP Blog:
Using Guzzle with Twitter via Oauth
July 31, 2014 @ 10:54:01

Continuing on with his series about using the Guzzle PHP HTTP library, Miguel Ibarra Romero is back with this new post showing how to connect your PHP application, via Guzzle, to the Twitter OAuth protected service.

In a previous article, we found out about Guzzle and how it can aid us in the task of establishing communication with third party APIs over HTTP. We used it to get the output of a random number generator and for basic interaction with Github's API. [...] While interacting with Github's API we discovered that it supports basic authentication (sending plain username/password). But what if the API we want to use just offers OAUTH authentication?

He shows how to use Guzzle's own OAuth subscriber to make a basic connection to the API. He walks you through the installation of the subscriber (via Composer) and an example of its use. He explains each part of the code, giving a little background on where it fits into the OAuth request and where to put your API secret and key to make the connection work. Finally, he includes the code to handle the callback once the OAuth request is successful, grabbing the token data and adding it to the user session.

Michael Dowling:
A Case for Higher Level PHP Streams in PSR-7
July 15, 2014 @ 10:54:53

In his latest post Michael Dowling looks at a recently proposed PSR standard (the HTTP message one, created by him) and some of his thoughts around it and what it could do for the community.

There's been a lot of talk lately about the PSR HTTP message proposal, PSR-7. The purpose of the proposal is to create a shared interface that can be used by projects to interact with HTTP messages for both clients and servers. When I created the proposal, I envisioned the purpose is not to say projects that utilize HTTP messages need to make breaking changes to use the proposed interfaces, but rather give projects an interface for which they can create an adapter.

He points out that the major part of the proposal that's being debated is the message body methods and structure. He gives a quick overview of this API and how streams could fit in with it, providing a flexible abstraction layer over the actual data. He includes a few ideas for some functionality that could make streams work relatively easily with the proposal (using a StreamInterface):

  • No Auto-registering of stream protocols and filters
  • Exceptions cause warnings in stream wrappers and filters
  • Functionality is spread over many functions

He also shares an example (based around the Guzzle HTTP library) showing how this interface could be put to work. He also talks some about one of the major concerns voiced right now, getting the actual stream itself to work with, and shows how the "detach" method matches this goal.

CodeSamplez.com:
PHP HTTP Request With Guzzle
June 12, 2014 @ 11:55:07

If you're making HTTP requests in your applications and you haven't looked into using Guzzle, you're missing out on one of the most powerful, flexible HTTP tools out there. In this new post to the CodeSamplez.com site they introduce you to the tool and show you how to make a few sample requests.

If you are consuming some kind of API with complex PHP HTTP requests which doesn't provide a clean wrapper library, I can feel the nightmare you might be having. Same could be happen if you are yourself writing such kind of API wrapper as well. Here, I will try to introduce you with guzzle library and getting a quick start. This article is targeted for complete beginners, so if you are already somewhat experienced, you either might skip this or review it and help me improve it to fit as a robust getting started tutorial.

He covers some of the things that can be done with Guzzle (including connecting to APIs and scraping site data) and briefly mentions some alternatives to the tool. Code is included to make a first request: a simple call to the GitHub API that fetches URL information for other resources. He also includes an example of making a POST request and using the OAuth module that comes with Guzzle, making those requests easier.

Evert Pot:
HTTP/1.1 just got a major update.
June 10, 2014 @ 11:23:57

While not specific to PHP, the HTTP specification that defines how web applications talk has gotten a major update in its latest version. In his latest post Evert Pot summarizes some of these changes and how they'll impact the work you're doing.

The IETF just published several new RFCs that update HTTP/1.1 [...] These documents make the original specification for HTTP/1.1 obsolete. As a HTTP geek, this is a big deal.

These new RFCs include definitions of standards around message syntax and routing, conditional requests, authentication, the 308 status code and the forwarded HTTP extension. Evert gets into the details of some of the changes, pointing out the major changes first and places where ambiguity has been resolved. He also includes a list of other "interesting things that have changed" in these new specs including clarifications around dealing with unexpected whitespace, the removal of the default charset of ISO-8859-1 and that the 204, 404, 405, 414 and 501 status codes are now cacheable.
