What is this repository for?

This is a REST API microservice of the mail client. To automate the receipt of data through mail attachments. For example: you are sent price lists by email with attached file and you need to parse the attachments data.

This microservice based on high performance, extensible, minimalist Go web framework Echo, IMAP client go-imap. For logging i`m use Logrus

Config

• imap_port - IMAP port
• imap_user - username
• imap_password - password
• http_addr - server bind address and port
• log_level - Level of logs: debug | warn | error

Build

Before, you need a build programm or use a docker (be release later).

make build

The programm has been build app application.

Usage

Note

The following logic should be implemented in your application:

1. Read the messages in order and check for the from field, subject and attachment name
2. If the message suits us, then we get an attachment (blob)
3. Transfer the letter to one of the folders (LOADED|ERRORS). Well done!
4. Repeat

The following REST API is used:

Manage mailboxes (folders)

1. GET host/mails/list - response list of mailboxes (folders).
2. PUT host/mails/folder with JSON data: {"folder":"FOLDER_NAME"} - set current folder of mailbox.

List of messages

1. GET host/messages/list?page=1 - list messages with response header info of total pages X-Pagination-Page-Count
2. GET host/messages/last?count=100 - list of last messages. Use query parameter count- что бы указать кол-во элементов

View message (with attachments names)

GET host/messages/:uid - where uid - id message from list. Response data of message with array attachments.

Download attachment

GET messages/download/:uid?index=0

• :uid - id message from list
• index - index attachments from view attachment

Response: - blob data
