海外TECH	DEV Community	How to use symfony/mailer without the Symfony framework	https://dev.to/doekenorg/how-to-use-symfony-mailer-without-the-symfony-framework-123g	How to use symfony mailer without the Symfony frameworkOn August Fabien Potencier officially announced the end of maintenance for Swiftmailer Swiftmailer is being replaced by the symfony mailer package Because of the name you might think this package can only be used inside a Symfony project but that s not the case The naming only implies the package is created by Symfony So let s take a look at this package and how we can use it inside a project without any framework Introducing the componentsTo email a recipient you need three things a mailer service a transporter and of course a message MailerAs you might expect the symfony mailer package provides a MailerInterface with a corresponding Mailer service The Mailer service contains the main API and is responsible for sending the message to the appropriate receiver The interface only has one method send So the API is very basic and easy to understand To set up the mailer service a transporter is required TransporterA transporter is responsible for actually sending a message using a particular protocol The service must implement the TransporterInterface which also only contains a send method When you call the Mailer send method it will delegate this request to the provided TransportInterface send method Because there are many ways a mail can be sent there are also many transporters available By default this package includes the two most common transporters sendmail and smtp There are however many rd party transport services available A full list of these services can be found on the documentation site MessageThe most important part of sending a message is of course the message itself Symfony Mailer uses the symfony mime package This package provides a few handy objects for creating messages that follow the MIME standard One of these classes is Email which provides a high level API to quickly create an email message An Email is a data object that contains the message the recipient and any other useful headers This class is also Serializable UsageNow that we are familiar with the underlying components let s create a PHP program that sends an email via the sendmail protocol We ll create a new project by making an empty folder and running the following command inside it composer init n name symfony mailer testThis will create a tiny composer json file with the following content name symfony mailer test require To use symfony mailer inside our project we need to require it composer require symfony mailerNow we ll create an index php file and require the vendor autoload php file require once vendor autoload php Now we ll create the email message we want to send use Symfony Component Mime Email email new Email gt from sender example test gt to your email here test gt priority Email PRIORITY HIGHEST gt subject My first mail using Symfony Mailer gt text This is an important message gt html lt strong gt This is an important message lt strong gt As you can see the API for creating an Email is very verbose and easy to understand You might have noticed we provided the content twice as text and as HTML When the email client used to read the mail supports HTML it will show that version otherwise it will fall back to the text only version Now that our Email is done We can add our transport service and the mailer instance use Symfony Component Mailer Mailer use Symfony Component Mailer Transport SendmailTransport transport new SendmailTransport mailer new Mailer transport mailer gt send email Now we should be able to send this message We can try it out by running it from the command line php index phpAnd there you have it You ve just sent a mail using symfony mailer Using a DSNThere is one more thing I d like to show you and that is creating a transporter based on a DSN If you are unfamiliar with the term DSN stands for Data Source Name It is a string that represents the location of a data source This data source can be anything like a file location a database connection or in our case a mail transport driver There is no real definitive format for a DSN other than it is a string Symfony however has chosen to make their DSNs mirror a URI So this format should be pretty familiar to you If I were to say to you for example Create a url based on the ftp protocol for the doeken org domain with username john and password doe on port You would probably give me a string like this ftp john doe doeken org In the case of a transporter DSN the protocol is the name of the sender so in our case sendmail So that would make our DSN sendmail This is however not a valid URI because there is no domain To fix this we can add a random string but most prefer default That means the final DSN is sendmail default We can now use the Transport fromDSN method to automatically create the appropriate transport service use Symfony Component Mailer Transport Transport transport Transport fromDsn sendmail default transport will now still hold a SendmailTransport instance and the sending of the mail will still work If you wanted to send a mail using the smtp protocol you can provide a similar DSN I like using HELO to debug my emails A DSN for this could be smtp symfony mailer TestingFor testing purposes symfony mailer includes a NullTransport service This transporter will not send any mail but it will trigger all the appropriate events You can create this transporter using the null default DSN EventsI won t be covering events in this blog post but this is something that symfony mailer supports As of version the only event dispatcher package you can use is symfony event dispatcher When is released and Swiftmailer will officially be retired you can use any PSR event dispatcher Do you want to learn more about event dispatching Then you should check out my in depth post on Event Dispatching DocumentationIf you want to learn more about the symfony mailer package I highly recommend reading the docs It goes into a lot of detail on the possible transport services as well as using multiple transports at the same time or even sending mails asynchronous by using a message queue	2021-09-11 10:07:14
