In this guide you will learn how to send SMS
messages from Perl using HTTP request with the help of Ozeki NG SMS Gateway.
The explanation on its use and the sample source code will be provided as well.
Introduction
To send data from one application to another you can apply
HTTP as it is the simplest method for this purpose. Perl has the ability to
calls to submit HTTP requests, therefore it can be used to send SMS text
messages to cellphones. To achieve SMS functionality you need to install a
stable SMS gateway such as Ozeki NG SMS Gateway. With this software product you
can operate with SMS messages with the use of HTTP GET or HTTP POST method calls
(Figure 1).
Figure 1 - How to send SMS messages from Perl SMS API through HTTP
After the installation, this solution will work as follows:
to start to send SMS messages first messages have to be forwarded to the
SMS Gateway. The built-in webserver of the gateway provides an
HTTP SMS API that allows to
submit messages. After the messages arrived at the SMS gateway they will be
forwarded to the mobile network either with a GSM modem attached to the
computer with a data cable, or the gateway directly connects to the SMS center
of the mobile service provider over the Internet.
Prerequisites
To setup and operate this solution properly you need the
follows:
To send SMS messages from Perl using HTTP requests, first
you need to download, install and configure Ozeki
NG SMS Gateway software to your computer. Then import the source code
provided below into a new project you write in Perl. After you imported
it you can configure the code in the following way: In "host" variable replace
127.0.0.1. to the IP address on which Ozeki NG SMS Gateway has been installed.
(In our example it is on the local computer that is why its IP address is
127.0.0.1. Replace "user_name" and "user_password" to the values with which
you log into Ozeki NG SMS Gateway. Then replace the recipient to the intended
recipient. In the message body you can type your message. Next, the example will
piece together the HTTP request and then query it. Finally, it will verify
whether the SMS sending is successful. In case of success you will read:
"Message successfully sent", while if there was a problem the following message
appears: "Message not sent! Please check your settings". Please note that you
need to customize the values in the source code below.

#### Sending the message ###
################################################
$request = HTTP::Request->new(GET=>$url);
$useragent = LWP::UserAgent->new;
$response = $useragent->request($request);

### Verifying the response ###

if ($response->is_success) {
print "Message successfully sent"
} else {
print "Message not sent! Please check your settings!"
