How to send multiple sms from Ruby

The most simple way to send multiple SMS from Ruby is to use the built in HTTP/Rest SMS api of Ozeki SMS Gateway. When you use this API, you will send SMS messages by issuing a HTTP Post request to the SMS gateway. The HTTP Post request will contain a message formatted in json format. The SMS gateway will send this SMS to the recipient phone, and it will return a HTTP 200 OK response to your request.

SendMultipleSms.rb
require 'ozeki_libs_rest'

configuration = Configuration.new(
    "http_user",
    "qwe123",
    "http://127.0.0.1:9509/api"
);

msg1 = Message.new
msg1.to_address = "+36201111111"
msg1.text = "Hello world 1"

msg2 = Message.new
msg2.to_address = "+36202222222"
msg2.text = "Hello world 2"

msg3 = Message.new
msg3.to_address = "+36203333333"
msg3.text = "Hello world 3"

api = MessageApi.new(configuration)

result = api.send([ msg1, msg2, msg3 ])

print(result)
	

How to use the Ruby sms example:

This Ruby sms example can be used in any ruby application. To use it, you must download the ozeki_libs_rest gem. After the gem is downloaded, you need to add a reference to it in your Ruby source code. This will allow you to use the classes provided by the ozeki_libs_rest gem. You can use the Message class to create the SMS. You can use the MessageApi class to send the SMS to the SMS gateway. The SMS gateway will forward your message to the mobile network either through a wireless connection or through the Internet.

How to send multiple sms from Ruby (Quick steps)

To send multiple sms from Ruby:

  1. Download the SendMultipleSms.rb.zip file
  2. Extract the .zip file from Downloads folder
  3. Open the SendMultipleSms.rb file in any text editor like windows notepad
  4. Launch Ozeki SMS Gateway
  5. Create a HTTP API user in Ozeki
  6. Run SendMultipleSms.rb Ruby code using the command prompt
  7. Check the Sent box in Ozeki SMS Gateway

Install Ozeki SMS Gateway and create an HTTP API user

To be able to send SMS from Ruby, first you need to install Ozeki SMS Gateway. The SMS gateway can be installed on the same computer, where you develop your Ruby code in Visual studio. After installation, the next step is to connect Ozeki SMS Gateway to the mobile network. You can send a test sms from the Ozeki GUI to verify, that your mobile network connection works. The final step to prepare your environment is to create a HTTP sms api user. Create a user with a username of "http_user", and with a password of "qwe123" to make the example work without modification.

After the environment is setup, you can run your Ruby code.

HTTP API url to use send sms from Ruby

To send SMS from Ruby, your Ruby will will have to issue an HTTP request to the SMS gateway. The API url is shown below. Note that the IP address (127.0.0.1) should be replaced to the IP address of your SMS gateway. If Ozeki SMS Gateway is installed on the same computer where the Ruby sms application is running, this can be 127.0.0.1. If it is installed on a different computer it should be the IP address of that computer.

http://127.0.0.1:9509/api?action=rest
	

HTTP authentication to use send sms from Ruby

To authenticate the Ruby sms client, you need to send the username and password in a base64 encoded string to the server in a HTTP request. The format used is: base64(username+":"+password). In Ruby you can use the following code to do this encoding:

username_password = username + ':' + password
username_password_encoded = Base64.encode64(username_password)
'Basic ' + username_password_encoded
	

For example if you encode the username 'http_user' and the password 'qwe123', you will get the following base64 encoded string: aHR0cF91c2VyOnF3ZTEyMw==. To send

HTTP request header to send SMS from Ruby

To send the SMS messages, you need to include the following lines as headers in the HTTP request. Note that we include a content type and an Authorization header.

Content-Type: application/json
Authorization: Basic QWxhZGRpbjpvcGVuIHNlc2FtZQ==
	

HTTP request to send SMS from Ruby

To submit the SMS, your Ruby application will send an HTTP request similar to the one below. Note, that this requst contains a HTTP header part and a http body part. The HTTP body is a JSON encoded data string. It contains the recipient number and the messages text.

POST /api?action=sendmsg HTTP/1.1
Content-Length: 992
Content-Type: application/json
Accept: application/json
Accept-Encoding: gzip;q=1.0,deflate;q=0.6,identity;q=0.3
Authorization: Basic aHR0cF91c2VyOnF3ZTEyMw==

HTTP response received by the Ruby sms example

Once the SMS gateway receives this request, it will generate a HTTP response. The HTTP response will contain a status code, to indicate whether the SMS submit request was successful or not. It will also return a JSON encoded structure to provide you useful details about the messages submission.
