Asynchronous Twitter client compatible with mpyw/co Generator-based flows.

NOTE, _(*1)

This project is forked for my own use. The dependency is less restrictive than the original project's one, and it maybe cause a problem which I will NOT fix., _(*2)

Quick examples

Prepare requirements

require __DIR__ . '/vendor/autoload.php';

use mpyw\Co\Co;
use mpyw\Co\CURLException;
use mpyw\Cowitter\Client;
use mpyw\Cowitter\HttpException;

Create client

$client = new Client(['CK', 'CS', 'AT', 'ATS']);

Synchronous requests

// Search tweets
$statuses = $client->get('search/tweets', ['q' => 'cowitter'])->statuses;
var_dump($statuses);

// Update tweet
$client->post('statuses/update', ['status' => 'Cowitter is the best twitter library for PHP!']);

// Update tweet with multiple images
$ids = [
    $client->postMultipart('media/upload', ['media' => new \CURLFile('photo01.png')])->media_id_string,
    $client->postMultipart('media/upload', ['media' => new \CURLFile('photo02.jpg')])->media_id_string,
];
$client->post('statuses/update', [
    'status' => 'My photos',
    'media_ids' => implode(',', $ids),
]);

// Listen user streaming
$client->streaming('user', function ($status) {
    if (!isset($status->text)) return;
    printf("%s(@s) - %s\n",
        $status->user->name,
        $status->user->screen_name,
        htmlspecialchars_decode($status->text, ENT_NOQUOTES)
    );
});

Asynchronous requests

// Search tweets
Co::wait(function () use ($client) {
    $statuses = (yield $client->getAsync('search/tweets', ['q' => 'cowitter']))->statuses;
    var_dump($statuses);
});

// Rapidly update tweets for 10 times
$tasks = [];
for ($i = 0; $i < 20; ++$i) {
    $tasks[] = $client->postAsync('statuses/update', [
        'status' => str_repeat('!', $i + 1),
    ]);
}
Co::wait($tasks);

// Rapidly update tweet with multiple images
Co::wait(function () use ($client) {
    $info = yield [
        $client->postMultipartAsync('media/upload', ['media' => new \CURLFile('photo01.png')]),
        $client->postMultipartAsync('media/upload', ['media' => new \CURLFile('photo02.png')]),
    ];
    yield $client->postAsync('statuses/update', [
        'status' => 'My photos',
        'media_ids' => implode(',', array_column($info, 'media_id_string')),
    ]);
});

// Listen filtered streaming to favorite/retweet at once each tweet
Co::wait($client->streamingAsync('statuses/filter', function ($status) use ($client) {
    if (!isset($status->text)) return;
    printf("%s(@s) - %s\n",
        $status->user->name,
        $status->user->screen_name,
        htmlspecialchars_decode($status->text, ENT_NOQUOTES)
    );
    yield Co::SAFE => [ // ignore errors
        $client->postAsync('favorites/create', ['id' => $status->id_str]),
        $client->postAsync("statuses/retweet/{$status->id_str}"),
    ];
}, ['track' => 'PHP']));

// Rapidly update with MP4 video
Co::wait(function () use ($client) {
    $file = new \SplFileObject('video.mp4', 'rb');
    $on_uploading = function ($percent) {
        echo "Uploading ... ({$percent}%)\n";
    };
    $on_processing = function ($percent) {
        echo "Processing ... ({$percent}%)\n";
    };
    yield $client->postAsync('statuses/update', [
        'status' => 'My video',
        'media_ids' => (yield $client->uploadVideoAsync($file, $on_uploading, $on_processing))->media_id_string,
    ]);
    echo "Done\n";
});

Handle exceptions

try {

    // do stuff here
    $client->get(...);
    $client->post(...);

} catch (HttpException $e) {

    // cURL communication successful but something went wrong with Twitter APIs.
    $message = $e->getMessage();    // Message
    $code    = $e->getCode();       // Error code (-1 if not available)
    $status  = $e->getStatusCode(); // HTTP status code

} catch (CURLException $e) {

    // cURL communication failed.
    $message = $e->getMessage();    // Message    (equivalent to curl_error())
    $code    = $e->getCode();       // Error code (equivalent to curl_errno())

}

or, _(*4)

try {

    // do stuff here
    $client->get(...);
    $client->post(...);

} catch (\RuntimeException $e) {

    // Something failed.
    $message = $e->getMessage();

}

Avoiding SSL errors due to the old libcurl version

If you encountered SSL certificate problem error..., _(*5)

1. Download the latest cacert.pem from official libcurl site.
   https://curl.haxx.se/docs/caextract.html
2. Please choose either of the following solutions.

2-A: Configure globally

Specify the path as curl.cainfo in your php.ini., _(*6)

curl.cainfo="C:\foo\bar\baz\cacert.pem"

DO NOT forget restarting Apache., _(*7)

2-B: Configure locally

Specify the path as CURLOPT_CAINFO. Using the magic constant __DIR__ is recommended., _(*8)

$client = new Client(['CK', 'CS', 'AT', 'ATS'], [CURLOPT_CAINFO => __DIR__ . '/cacert.pem']);

or, _(*9)

$client = new Client(['CK', 'CS', 'AT', 'ATS']);
$client = $client->withOptions([CURLOPT_CAINFO => __DIR__ . '/cacert.pem']);
