Make A Request

HttpClient is a simple class to make restful request.

use Asika\Http\HttpClient;

$http = new HttpClient;

$response = $http->get('http://example.com/?foo=bar');

// This is PSR7 ResponseInterface
(string) $response->getBody();

Other Methods

$http = new HttpClient;

// The post data can be query string or array
$response = $http->post('http://example.com/?foo=bar', array('post_data' => 'data'));
$response = $http->put('http://example.com/?foo=bar', array('post_data' => 'data'));
$response = $http->patch('http://example.com/?foo=bar', array('post_data' => 'data'));
$response = $http->delete('http://example.com/?foo=bar', array('post_data' => 'data'));

$response = $http->head('http://example.com/?foo=bar');
$response = $http->trace('http://example.com/?foo=bar');
$response = $http->options('http://example.com/?foo=bar');

// With headers
$response = $http->get('http://example.com/', null, array('X-Foo' => 'Bar'));

// Use request()
$response = $http->request('POST', 'http://example.com/?foo=bar', 'this=is&post=data');

Use Psr RequestInterface to Make Request

Psr7 Request is a immutable object, you have to get the return object every operation.

use Asika\Http\Request;

$request = new Request;

// Note: You have to get the return value.
// Every change will return new object.
$request = $request->withRequestTarget('http://example.com/flower/sakura')
    ->withMethod('POST')
    ->withAddedHeader('Authorization', 'Bearer ' . $token)
    ->withAddedHeader('Content-Type', 'application/text');

// OR
$request = new Request(
    'http://example.com/flower/sakura',
    'POST',
    'php://memory',
    array(
        'Authorization' => 'Bearer ' . $token,
        'Content-Type'  => 'application/json',
    )
);

// This is a POST request so we write post data to body
$request->getBody()->write('this=is&post=data');

$http = new HttpClient;

// Send request
$response = $http->send($request);

Use Uri and Json output.

use Asika\Http\Request;
use Asika\Http\Uri\PsrUri;

$request = (new Request)
    ->withUri(new PsrUri('http://example.com'))
    ->withMethod('POST')
    ->withAddedHeader('Authorization', 'Bearer ' . $token)
    ->withAddedHeader('Content-Type', 'application/json') // Use JSON
    
    // Note: Request will ignore path and query in Uri
    // So we have to set RequestTarget here
    ->withRequestTarget('/path/of/uri?flower=sakura');

// If you want to set a non-origin-form request target, set the
// request-target explicitly:
$request = $request->withRequestTarget((string) $uri);       // absolute-form
$request = $request->withRequestTarget($uri->getAuthority(); // authority-form
$request = $request->withRequestTarget('*');                 // asterisk-form

// This is JSON request so we encode data here
$request->getBody()->write(json_encode($data));
$response = $http->send($request);

$response->getStatusCode(); // 200 is OK

Custom Transports and Options

Now support Curl and Steam 2 transports.

use Asika\Http\Transport\CurlTransport;

$options = array(
    'certpath' => '/custom/cert.pem'
);

$transport = new CurlTransport($options);

// Set transport when client new
$http = new HttpClient(array(), $transport);

Set custom CURL options:

$options = array(
    'options' => array(
        CURLOPT_SSL_VERIFYHOST => false,
        CURLOPT_SSL_VERIFYPEER => true
    )
);

$httpOptions = array(
    'headers' => array(
        'X-Foo' => 'Bar'
    )
);

$http = new HttpClient($httpOptions, new CurlTransport($options));

Download Remote File

$http = new HttpClient;

$dest = '/path/to/local/file.zip';

$response = $http->download('http://example.com/file.zip', $dest);

if ($response->getStatusCode() != 200)
{
    // Error
}

Response Interface

Response object holds a Stream object to store returned string.

// The return value is: 'FOO BAR'
$body = $response->getBody();

// Simply to string
(string) $body; // FOO BAR

$body->seek(2);
$body->getContents(); // O BAR

$body->rewind();
$body->read(5); // FOO B

$body->getSize(); // 7

Uri

Uri is a simple Uri object to modify URL but not Psr UriInterface.

The methods provided in the Uri class allow you to manipulate all aspects of a uri. For example, suppose you wanted to set a new uri, add in a port, and then also post a username and password to authenticate a .htaccess security file. You could use the following syntax:

// new uri object
$uri = new Asika\Http\Uri\Uri;

$uri->setHost('http://localhost');
$uri->setPort('8888');
$uri->setUser('myUser');
$uri->setPass('myPass');

echo $uri->__toString();

This will output:

myUser:myPass@http://localhost:8888

If you wanted to add a specific filepath after the host you could use the setPath() method:

// set path
$uri->setPath('path/to/file.php');

Which will output

myUser:myPass@http://localhost:8888path/to/file.php

Adding a URL query:

// url query
$uri->setQuery('foo=bar');

Output:

myUser:myPass@http://localhost:8888path/to/file.php?foo=bar

PsrUri

PsrUri is a Uri object implemented the Psr UriInterface.

This object is also immutable, so we must get return value as new object every change.

$uri = (new PsrUri('http://example.com'))
    ->withScheme('https')
    ->withUserInfo('user', 'pass')
    ->withPath('/path/to/target')
    ->withQuery('flower=sakura')
    ->withFragment('#hash');
    
(string) $uri; // https://user:pass@example.com/path/to/target?flower=sakura#fragment

Stream

Stream is a powerful stream wrapper.

Read write data to memory:

$stream = new Stream('php://memory', 'wb+');

$stream->write('Foo Bar');

$stream->rewind(); // Back to begin

// Now we take something we wrote into memory

$stream->__toString(); // get: Foo Bar

// OR

$stream->rewind();
$stream->getContents(); // get: Foo Bar

Read data from php://input

$stream = new PhpInputSteam;

$data = $stream->__toString(); // foo=bar

$query = \Asika\Http\Uri\UriHelper::parseQuery($data); // array('foo' => 'bar')

Read file:

$stream = new Stream('/path/to/file.txt', 'r+');

$stream->__toString(); // Read

$steam->seek($stream->getSize());
$steam->write('new string'); // Write

Quick copy stream.

// Remote source
$src = new Stream('http://example/test.txt');

// Local store
$dest = new Stream('/path/to/local/test.txt');

// Do copy
\Asika\Http\Helper\StreamHelper::copy($src, $dest);

// Get Data
$dest->rewind();
$data = $dest->getContents();

Other Http Message Objects

`ServerRequest`

A Request object to store server data, like: $_SERVER, $_COOKIE, $_REQUEST etc.

`UploadedFile`

An object to store uploaded files, see: Uploaded files interface

$files = array();

foreach ($_FILE as $name => $file)
{
    $files[$name] = new UploadedFile($file['tmp_name'], $file['size'], $file['error'], $file['name'], $file['type']);
}

$request = new ServerRequest(
  $_SERVER,
  $_GET,
  $_POST,
  $_COOKIE,
  $files
);
