This library provides a scala interface to the Postmark API.
Inspiration has been taken from https://github.com/jaredholdcroft/postmark-java, so thanks to Jared for that.
Please note that support for Scala 2.9.x was dropped at version 1.1.1.
Add the dependency to SBT:
libraryDependencies += "com.github.sebrichards" %% "postmark-scala" % "1.3"
The PostmarkClient is simple enough to use:
import com.github.sebrichards.postmark.Attachment import com.github.sebrichards.postmark.NameValueMap import com.github.sebrichards.postmark.PostmarkClient import com.github.sebrichards.postmark.PostmarkError import com.github.sebrichards.postmark.PostmarkMessage import com.github.sebrichards.postmark.PostmarkSuccess import java.io.File import org.apache.commons.codec.binary.Base64 val client = new PostmarkClient("POSTMARK_API_TEST") val message = PostmarkMessage( // Required fields To = "Recipient <email@example.com>", From = "Postmark Sender <firstname.lastname@example.org>", Subject = "Test E-Mail", TextBody = Some("Hello world"), HtmlBody = Some("<p>Hello world</p>"), // Optional mail fields Cc = Some("Another Recipient <email@example.com>"), Bcc = Some("firstname.lastname@example.org"), ReplyTo = Some("email@example.com"), // Optional attachments Attachments = List( Attachment("Text File.txt", "text/plain", Base64.encodeBase64String("Hello world".getBytes)), Attachment(new File("picture.jpg")) ), // Optional Postmark fields Tag = Some("My Tag"), Headers = List( NameValueMap("key", "value"), NameValueMap("key2", "value2") ), TrackOpens = true ) val result: Either[PostmarkError, PostmarkSuccess] = client.send(message) client.destroy
Alternatively, you can use the
PostmarkAutoRetryClient to automatically retry when there's an error at Postmark's end.
Note that the
send method will block until either success or eventual failure.
All optional fields default to None/Nil.
Some additional points:
- You need to add your own flavour of SLF4J implementation as a dependency.
- If you're finished using the Postmark client, call the
destroymethod before dereferencing it.
The client expects the following HTTP codes from Postmark: 200, 401, 422 and 500.
- For 200, the provided JSON is parsed into
- For 401/422, the provided JSON is parsed into
- For 500, a
PostmarkErroris created using the response body.
Note that when using the
PostmarkAutoRetryClient, responses with 401/422 are accepted as valid, thus the request will not be re-attempted.
Only responses with 500 are deemed worthy of a retry. If this isn't suitable for you, you can easily extend PostmarkClient with your own approach.
