How to extract data from multipart/mixed request in Spray

Reading Time: < 1 minute

If you are getting multipart/mixed response then how should we handle that in spray so that we can extract all the data from that.

Suppose we are getting email request in which contains all the information such as: from , to, attachment etc.

So here is the way to extract those :

entity(as[MultipartContent]) { emailData =>
post {
val dataInParts = emailData.parts.seq map {
emailPart => (emailPart.name.get -> emailPart)
}
val dataInPartsMap = Map(dataInParts: _*)
val from= dataInPartsMap("From").entity.data.asString
val totalAttachment = dataInPartsMap("attachment-count").entity.data.asString.toInt
// If you want to find attachment details.
for (i <- 1 to totalAttachment) {
val fileType = dataInPartsMap("attachment-" + i).headers(1).value
val fileSize = dataInPartsMap("attachment-" + i).headers(0).value.toLong
val fileName = dataInPartsMap("attachment-" + i).filename.get
}
complete("OK")
}
}
