Guzwrap
==============================================

Guzwrap is an object-oriented wrapper around [GuzzleHttp](http://guzzlephp.org/).

This project is founded to make sending request with Guzzle easier and enjoyable.

## Supported PHP Versions
Guzwrap require **PHP >= 7.4 or >= 8.0**.

# Installation

Make sure you have [Composer](http://getcomposer.org) installed.

```bash
composer require ahmard/guzwrap
```

# Usage

```php
use Guzwrap\Request;

//simple request
$result = Request::get('http://localhost:8002')->exec();

//with authentication
Request::get('http://localhost:8002')
->auth('username', 'password')
->exec();
```

- get Guzwrap Instance

```php
use Guzwrap\Request;

$instance = Request::create();
//Do something...
```

- Request with cookies

```php
use Guzwrap\Request;

Request::create()->get('http://localhost:8002')
->withCookie()
//or use cookie file
->withCookieFile('path/to/file')
//use cookie session
->withCookieSession('session_name')
//use array too
->withCookieArray([
'first_name' => 'Jane',
'other_names' => 'Doe'
], 'localhost')
//Use single cookie across requests
->withSharedCookie();
```

- Handle redirects

```php
use Guzwrap\Request;
use Guzwrap\Wrapper\Redirect;

Request::get('http://localhost:8002')
->redirects(function(Redirect $redirect){
$redirect->max(5);
$redirect->strict();
$redirect->referer('http://goo.gl');
$redirect->protocols('http');
$redirect->trackRedirects();
$redirect->onRedirect(function(){
echo "Redirection detected!";
});
})->exec();
```

- Headers

```php
use Guzwrap\Request;
use Guzwrap\Wrapper\Header;

Request::get('http://localhost:8002')
->header(function(Header $header){
$header->add('hello', 'world');
$header->add('planet', 'earth');
})
->exec();
```

- Query

```php
use Guzwrap\Request;

Request::get('https://google.com')
->query('q', 'Who is jane doe')
->exec();
```

- Post form data

```php
use Guzwrap\Request;
use Guzwrap\Wrapper\Form;

Request::uri('http://localhost:8002')
->post(function(Form $form){
$form->field('first_name', 'Jane');
$form->field('last_name', 'Doe');
})
->exec();

//Post with multipart data
Request::uri('http://localhost:8002')
->post(function(Form $form){
$form->method('post');
$form->field('full_name', 'Jane Doe');
$form->file('avatar', 'C:\jane_doe.jpg');
})->exec();
```

You can use [RequestInterface::form()](src/RequestInterface.php) method

**Note:** If you did not set form method to post,
all your input fields will be treated as url queries.

```php
use Guzwrap\Request;
use Guzwrap\Wrapper\Form;
use Guzwrap\Wrapper\File;

Request::form(function (Form $form){
$form->method('get'); //You can use any http method here
$form->action('localhost:8002');
$form->field('name', 'Guzwrap');
})->exec();

//Send file with custom information
Request::form(function(Form $form){
$form->method('post');
$form->action('http://localhost:8002');
$form->field('full_name', 'Jane Doe');
$form->file(function(File $file){
$file->field('avatar');
$file->path('C:\jane_doe.jpg');
$file->name('John_doe.gif');
});
})->exec();
```

### More _Request_ usage

- Use request data

```php
use Guzwrap\Request;
use Guzwrap\UserAgent;

//Basic usage
$request = Request::query('artist', 'Taylor Swift')
->useData([
'headers' => [
'pass' => 'my-random-pass',
'user-agent' => 'My Custom Useragent',
],
'query' => [
'action' => 'create'
]
])->exec();

//User other request's data
$request1 = Request::userAgent(UserAgent::FIREFOX)
->query([
'username' => 'Ahmard',
'realm' => 'admin'
]);

$realRequest = Request::useData($request1->getData());
```

- Use request object

```php
use Guzwrap\Request;
use Guzwrap\UserAgent;

$request1 = Request::query('username', 'Ahmard');

$request2 = Request::query('language', 'PHP')
->userAgent(UserAgent::CHROME)
->allowRedirects(false);

$realRequest = Request::useRequest($request1, $request2); //Has request 1 and request 2 data
```

### Asynchronous Operations

```php
use Guzwrap\Request;
use Psr\Http\Message\ResponseInterface;

$promise = Request::get('localhost:8002')
->query('wraps', 'guzzlehttp')
->query('name', 'guzwrap')
->execAsync();

$promise->then(function (ResponseInterface $response){
var_dump($response->getBody()->getContents());
});

$promise->wait();
```

- **Running multiple requests at once**

* Create [PHP Built-in Server](https://www.php.net/manual/en/features.commandline.webserver.php)
```bash
php -S localhost:8002 index.php
```

* Create an **index.php** file and put below code into it
```php
\sleep($_GET['sleep']);
echo $_GET['sleep'];
```

* Crate **test.php** and put below code into it
```php
use Guzwrap\Request;
use Psr\Http\Message\ResponseInterface;

$promise = Request::get('localhost:8002')
->query('wraps', 'guzzlehttp')
->query('sleep', 2)
->execAsync();

$promise->then(function (ResponseInterface $response){
var_dump($response->getBody()->getContents());
});

$promise2 = Request::get('localhost:8002')
->query('name', 'guzwrap')
->query('sleep', 1)
->execAsync();

$promise2->then(function (ResponseInterface $response){
var_dump($response->getBody()->getContents());
});

$promise->wait();
$promise2->wait();
```

* Now run the **test.php** file
```bash
php test.php
```

- **Using [Concurrent](src/Wrapper/Client/Concurrent.php) class
to manage [Guzzle Request Concurrency](https://docs.guzzlephp.org/en/stable/quickstart.html#concurrent-requests)**
```php
use Guzwrap\Request;

$promise1 = Request::get('localhost:8002')->execAsync();
$promise2 = Request::get('localhost:8002')->execAsync();

$responses = Request::concurrent($promise1, $promise2)->unwrap();

echo $responses[0]->getStatusCode() . PHP_EOL;
echo $responses[1]->getReasonPhrase() . PHP_EOL;
```

* **Using request pool**
```php
use Guzwrap\Request;
use Guzwrap\Wrapper\Pool;
use GuzzleHttp\Exception\RequestException;
use GuzzleHttp\Psr7\Response;
use Psr\Http\Message\ResponseInterface;

require 'vendor/autoload.php';

$pool = Request::pool(function (Pool $pool) {
$pool->concurrency(5);
$pool->fulfilled(function (Response $response, $index) {
// this is delivered each successful response
});
$pool->rejected(function (RequestException $reason, $index) {
// this is delivered each failed request
});

$pool->requests(function ($total) {
$uri = 'http://127.0.0.1:8002';
for ($i = 0; $i < $total; $i++) {
yield new \GuzzleHttp\Psr7\Request('GET', $uri);
}
});
});

$promise = $pool->promise();

$promise->then(function (ResponseInterface $response){
echo "{$response->getStatusCode()} @ {$response->getReasonPhrase()}\n";
});

$promise->wait();
```

### UserAgent

We provide custom user agents to help send request easily.

```php
use Guzwrap\Request;
use Guzwrap\UserAgent;

Request::userAgent(UserAgent::CHROME);

//Choose specific useragent index from array
Request::userAgent(UserAgent::CHROME, '1');

//Choose sub-useragent
Request::userAgent(UserAgent::CHROME, '9.1');
```

- List user agents

```php
use Guzwrap\UserAgent;

$userAgents = UserAgent::init()->getAvailable();
```

- Get random user agent

```php
use Guzwrap\UserAgent;

$randomUA = UserAgent::init()->getRandom();
```

- Add user agents to the collection.

Please take a look at user agent [definition sample](/src/data/ua/chrome.json)

```php
use Guzwrap\UserAgent;

UserAgent::init()->addFile('/path/to/user-agents.json');
```

- Use raw user agent

Note that you can only pass Guzwrap\UserAgent class to the request object, nothing more.

This may open door to other possibilities in the future.

```php
use Guzwrap\UserAgent;
use Guzwrap\Request;

$request = Request::userAgent(UserAgent::raw('Browser 1.0 (Windows NT 10.0; Win64; x64)'));
```

### Stack
Manipulating Guzzle [StackHandler](https://docs.guzzlephp.org/en/stable/handlers-and-middleware.html#handlerstack)

```php
use Guzwrap\Request;
use GuzzleHttp\Handler\CurlHandler;
use GuzzleHttp\HandlerStack;

Request::stack(function (HandlerStack $stack){
$stack->setHandler(new CurlHandler());
//Do something here
});
```

### Middleware
Adding [middleware](https://docs.guzzlephp.org/en/stable/handlers-and-middleware.html#middleware) to GuzzleHttp requests

```php
use Guzwrap\Request;
use Psr\Http\Message\RequestInterface;

/**
* An example of middleware that add header to requests
* @link https://docs.guzzlephp.org/en/stable/handlers-and-middleware.html
*/
Request::middleware(function(){
return function (callable $handler){
return function (
RequestInterface $request,
array $options
) use ($handler){
$request = $request->withHeader('X-Guzwrap-Version', 'V2');
return $handler($request, $options);
};
};
});
```

### Extending Guzwrap

```php
use Guzwrap\Wrapper\Guzzle;
use Psr\Http\Message\ResponseInterface;

require 'vendor/autoload.php';

class Client extends Guzzle
{
public static function create(): Client
{
return new Client();
}

public function boom(): ResponseInterface
{
echo "Executing request...\n";
return parent::exec();
}
}

$client = Client::create()
->get('localhost:8002')
->withCookie()
->boom();
```

## Testing
Rust PHP built-in server before running the test
```
php -S localhost:8002 -t tests/raw/
```

Run the test
```
composer test
```

**Enjoy 😎**
