Microservice-EmailSender

API for sending email messages

Configuration

You need to configure either the appsettings.json file

"Smtp": {
    "SmtpHost": "",
    "SmtpPort": 0,
    "UseSsl": true,
    "EmailAddress": "",
    "Password": ""
  }

or the docker-composer.yaml file

environment:
  - SMTPHOST=<smtp_host>
  - SMTPPORT=<port>
  - USESSL=<bool_value>
  - EMAILADDRESS=<email_address>
  - PASSWORD=<password>

SMTPHOST - server smtp

SMTPPORT - smtp server port

USESSL - is ssl is used

EMAILADDRESS - your email address

PASSWORD - password to addres

How to work with the application

To run the application, we need to have Docker or ASP.NET Core Runtime 9.0 installed.

If we plan to run the application as a container from an image in the dock, we use scripts:

build-docker.ps1 for windows

build-docker.sh for linux

Examples

PowerShell

This is a example for powershell:

$url = "http://host:4040/sendmail"
$contentType = "application/json"

$json = @{
  aliasFrom = "information come from send"
  to = @("[email protected]", "[email protected]")
  cc = @("[email protected]", "[email protected]")
  bcc = @("[email protected]", "[email protected]")
  subject = "subject message"
  bodyishtml = $False
  body = "body message"
} | ConvertTo-Json

Invoke-RestMethod -Uri $url -Method Post -Body $json -ContentType $contentType

C#

This is a example for C#:

using System.Text;
using System.Text.Json;

public class Program
{
    public static async Task Main()
    {
        var url = "http://host:4040/sendmail";
        var contentType = "application/json";

        using var client = new HttpClient();
        var values = new
        {
            Name = "information come from send",
            To = new List<string>(){ "[email protected]", "[email protected]" },
            Cc = new List<string>(),
            Bcc = new List<string>(),
            Subject = "subject message",
            BodyIsHtml = false,
            Body = "body message"
        };

        var jsonString = JsonSerializer.Serialize(values);
        var stringContent = new StringContent(jsonString, Encoding.UTF8, contentType);
        await client.PostAsync(url, stringContent);
    }
}

Python

This is a example for Python:

import requests

url = 'http://host:4040/sendmail'
data = {
  "name": "information come from send",
  "to": ["[email protected]", "[email protected]"],
  "cc": ["[email protected]", "[email protected]"],
  "bcc": ["[email protected]", "[email protected]"],
  "subject": "subject message",
  "bodyishtml": False,
  "body": "body message"
}
headers = {'Content-type': 'application/json'}

response = requests.post(url, json=data, headers=headers)

print(response)
