Go package used to handle the CloudMailin JSON Hash Email Message Format

Hi there! I’m a Systems Developer in Stockholm, Sweden.

cloudmailin's Issues

format changed

just tried this and it seems that the cloudmailin json format has changed so that everything is lowercased (even if the link that is in the readme says otherwise)

from requestbin:

a quick hack:

package cloudmailin

import (
	"encoding/json"
	"io"
)

// A SPF (Sender Policy Framework) result for the given IP address and Domain.
type SPF struct {
	Result string `json:"result"`
	Domain string `json:"domain"`
}

// Envelope contains the data sent or gathered from the remote server.
type Envelope struct {
	To         string   `json:"to"`
	Recipients []string `json:"recipients"`
	From       string   `json:"from"`
	HeloDomain string   `json:"helo_domain"`
	RemoteIP   string   `json:"remote_ip"`
	SPF        SPF      `json:"spf"`
}

// Headers contains all of the message headers extracted from the email.
type Headers struct {
	Received    string `json:"received"`
	Date        string `json:"date"`
	From        string `json:"from"`
	To          string `json:"to"`
	Bcc         string `json:"bcc"`
	MessageID   string `json:"message_id"`
	Subject     string `json:"subject"`
	MimeVersion string `json:"mime_version"`
	ContentType string `json:"content_type"`
}

// Attachments to the message
type Attachments struct {
	Content     string `json:"content"`
	URL         string `json:"url"`
	FileName    string `json:"file_name"`
	ContentType string `json:"content-type"`
	Size        int    `json:"size"`
	Disposition string `json:"disposition"`
}

// A Data struct contains all the fields of a decoded message
type Data struct {
	Headers     Headers       `json:"headers"`
	Envelope    Envelope      `json:"envelope"`
	Plain       string        `json:"plain"`
	HTML        string        `json:"html"`
	ReplyPlain  string        `json:"reply_plain"`
	Attachments []Attachments `json:"attachments"`
}

// Decode a message into a Data struct
func Decode2(r io.Reader) (Data, error) {
	var ret Data

	err := json.NewDecoder(r).Decode(&ret)

	return ret, err
}

headers.received can be an array

json: cannot unmarshal array into Go struct field Headers.headers.received of type string
