Mailer client

continuousphp , _(*1)

This is the client you should use to send email to Mail Api., _(*2)

The client can use two kind of transports to send emails:, _(*3)

Asynchronous transport implemented by BeanstalkProxyTransport
Synchronous transport implemented by BasicTransport

BeanstalkProxyTransport delegate the API consumption to workers by sending email properties to a Beanstalkd queue., _(*4)

BasicTransport use the classic HTTP layer to send emails., _(*5)

If asynchronous transport is set, it will act as default transport. Synchronous transport will be a fallback in case when asynchronous transport fails., _(*6)

Installation

Add this requirement to your composer.json: "fei/mailer-client": : "^1.0.0", _(*7)

Or execute composer.phar require fei/mailer-client in your terminal., _(*8)

Quick start

Let's start with a simple client :, _(*9)

<?php

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

use Fei\Service\Mailer\Client\Mailer;
use Fei\ApiClient\Transport\BasicTransport;
use Fei\Service\Mailer\Entity\Mail;

// The client
$mailer = new Mailer([
    Mailer::OPTION_BASEURL => 'https://api_host',
    Mailer::OPTION_HEADER_AUTHORIZATION => 'key'
]);
// Optional: a BasicTransport will be instantiate if no synchronous transport was found
$mailer->setTransport(new BasicTransport());

// The mail to send
$message = new Mail();
$message->setSubject('Test subject');
$message->setTextBody('This is a example message');
$message->addRecipient('to@test.com');
$message->setSender(array('sender@test.com'));

// And send !
$return = $mailer->transmit($message);

if ($return) {
    echo 'Mail transmit success' . PHP_EOL;
} else {
    echo 'Mail transmit failed' . PHP_EOL;
}

Keep in mind that you should always initialize a mailer client by a dependency injection component, since it requires at least one dependency, which is the transport. Moreover, the OPTION_BASEURL parameter should also depends on environment., _(*10)

Real world example

Below a more robust example which use the BeanstalkProxyTransport as default transport., _(*11)

<?php

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

use Fei\ApiClient\Transport\BasicTransport;
use Fei\ApiClient\Transport\BeanstalkProxyTransport;
use Fei\Service\Mailer\Client\Mailer;
use Fei\Service\Mailer\Entity\Mail;
use Pheanstalk\Pheanstalk;

$mailer = new Mailer([
    Mailer::OPTION_BASEURL => 'https://api_host',
    Mailer::OPTION_HEADER_AUTHORIZATION => 'key'
]);

$async = new BeanstalkProxyTransport();
$async->setPheanstalk(new Pheanstalk('host'));
// Async transport will be the default transport. 
$mailer->setAsyncTransport($async);
// If async transport fails, then BasicTransport will take over.
$mailer->setTransport(new BasicTransport());

$message = new Mail();
$message->setSubject('Test subject');
$message->setTextBody('This is a example message');
$message->addRecipient('to@test.com');
$message->setSender(array('sender@test.com'));

$return = $mailer->transmit($message);

if ($return) {
    echo 'Mail transmit success' . PHP_EOL;
} else {
    echo 'Mail transmit failed' . PHP_EOL;
}

To work properly, BeanstalkProxyTransport needs a instance of a Beanstalkd server able to listen to its requests. Workers will consume Beanstalkd messages tube (or queue) and will send email data to Mail API server., _(*12)

The message workflow:, _(*13)

Client -> Pheanstalkd -> Workers -> Mail API server

Use the logger

Mailer client is Logger client aware. You could set a logger instance like this example below in order to activate logging functionality., _(*14)

<?php

$logger = new Logger([
    Logger::OPTION_BASEURL => 'http://127.0.0.1:8082',
    Logger::OPTION_FILTER => Notification::LVL_INFO,
    Logger::OPTION_HEADER_AUTHORIZATION => 'key'
]);
$logger->setTransport(new BasicTransport());

$mailer = new Mailer([
    Mailer::OPTION_BASEURL => 'https://api_host',
    Mailer::OPTION_HEADER_AUTHORIZATION => 'key'
]);
$mailer->setTransport(new BasicTransport());
$mailer->setLogger($logger); // Set and activate the the logger functionality

As is each mail sent will be recorded with logger service., _(*15)

Email and attachments

Here a example if you need to send email with attachments :, _(*16)

<?php

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

use Fei\Service\Mailer\Client\Mailer;
use Fei\ApiClient\Transport\BasicTransport;
use Fei\Service\Mailer\Entity\Mail;
use Fei\Service\Mailer\Entity\Attachment;

$message = new Mail();
$message->setSubject('Test subject');
$message->setTextBody('This is a example message');
$message->setHtmlBody('

This is a example message!, _(*17)

');
$message->setRecipients(array('to@test.com' => 'Name', 'other@test.com' => 'Other Name'));
$message->addCc('cc@example.com', 'CC');
$message->addBcc('bcc@example.com', 'CC');
$message->setSender(array('sender@test.com' => 'The sender'));
$message->setReplyTo(array('steve@app.com' => 'Steve'));

// Add a attachment with a \SplObjectFile
$message->addAttachment(new \SplFileObject('/to/file/path/image.png'));

// Or add a attachment with a "generated string"
$attachment = array(
    'filename' => 'document.txt',
    'mime_type' => 'text/plain',
    // Note base64_encode
    'contents' => base64_encode('Hello world!') . PHP_EOL
);
$message->addAttachment($attachment);

// Or add a attachment object
$attachment = new Attachment('/to/file/path/document.pdf');
$attachment->setAttachmentFilename('another-filename.txt');
$attachment->setMimeType('text/plain');
$message->addAttachment($attachment);

$mailer = new Mailer([
    Mailer::OPTION_BASEURL => 'https://api_host',
    Mailer::OPTION_HEADER_AUTHORIZATION => 'key'
]);
$mailer->setTransport(new BasicTransport());
$mailer->transmit($message);

Embedding attachment

Sometime, you need to include image (or other media) inline in your message. You could use a resource URL in order to linking the media but this approach is usually blocked by mail clients. A another approach is to embed your media directly into your message., _(*18)

<?php

use Fei\Service\Mailer\Entity\Mail;
use Fei\Service\Mailer\Entity\Attachment;

$message = new Mail();

$embedded = (new Attachment('/my/picture.png', true));
$message->addAttachment($embedded);

$message->setTextBody('This is a example message');
$message->setHtmlBody(<<<HTML
<!doctype html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Example</title>
</head>
<body>
    <p>
        <img src="{$embedded->getCid()}" style="display: block; width: 100px; height: 100px; float: right;">
        This is example with a embedded image
    </p>
</body>
</html>
HTML
);

And that's it., _(*19)

Catch them all

In non production environment, you often don't need to send email to the real recipient. For testing purpose, you could initialize the client with the option OPTION_CATCHALL_ADDRESS and all email will be forwarded to email address passed to this option., _(*20)

<?php

use Fei\Service\Mailer\Client\Mailer;

$mailer = new Mailer([
    Mailer::OPTION_BASEURL => 'https://api_host',
    Mailer::OPTION_CATCHALL_ADDRESS => 'testing@email.com',
    Mailer::OPTION_HEADER_AUTHORIZATION => 'key'
]);

Add callback functions before Mail instance validation

For different needs, you could registered a callback to apply on Mail to be send before its state validation., _(*21)

You can see this as a another way to extends the "mailer-client" functionalities., _(*22)

<?php

use Fei\Service\Mailer\Client\Mailer;
use Fei\Service\Mailer\Entity\Mail;

$mailer = new Mailer();
$mailer->addCallbackBeforeValidation(function (Mail $mail) {
    $mail->setRecipients(['another@email.com']);
});

With this example, all Mail send with this client will have theirs recipients changed by another@email.com., _(*23)

We provide a couple of another method to manage callbacks:, _(*24)

Mailer::addFirstCallbackBeforeValidation: append a callback on the first place of the stack to be executed in contrast to addCallbackBeforeValidation which place the callback in the end of the chain execution.
Mailer::clearCallbackBeforeValidation: remove all callback registered in the stack

Pricer integration: meet the `PricerMailer` class

We provide a child class of Mailer for the Pricer need: PricerMailer., _(*25)

PricerMailer extends functionalities Mailer plus a callback which apply email filtering on the Mail instance to be send. Naturally, you can remove this filter or add yours own., _(*26)

Client option

Only one option is available which can be passed to the __construct() or setOptions() methods:, _(*27)

Option	Description	Type	Possible Values	Default
OPTION_BASEURL	This is the server to which send the requests.	string	Any URL, including protocol but excluding path	-
OPTION_CATCHALL_ADDRESS	Recipient to substitute to any other. When used, original recipients, ccs, bccs are prepended to mail body.	string	Any valid email address	-
OPTION_HEADER_AUTHORIZATION	Api Key for authentification	string	Any string value	''
