Upgrade Android/IOS App using Codeigniter Restful Webservices(API)

What is Restful Webservices :- It is nothing just a function. webservices are the api that is used to communicate with different technologies. It is also called api (Application Programming Interface) used for provide the interface between different application.

Now I would like to share webservice of upgrade app and force update app.

Here we will writeapp_version_check() webservice in codeigniter controller or any framework.

Step:1 app_version_check()webservice



public function app_version_check()
{
$os = $this->input->get_post('os');
$app = $this->input->get_post('app');
$version = $this->input->get_post('version');
if($os == '' || $app == '' || $version == '' )
{

$status="error";
$message="Please Enter Required Fields";
$response=$this->response_msg($status,$message);
}
else
{
$upgrade_required = $this->Home_model->app_version_check($os,$app,$version);

if(!isset($upgrade_required))
{
$is_upgrade_required="True";
$message="New version of connectosh Available";
$response=$this->response_msg($status,$message);
}
else
{
$is_upgrade_required="False";
$message="No Need to update";
$response=$this->response_msg($status,$message);
}

}
$this->output
->set_content_type('application/json')
->set_output(json_encode($response));

}

There are 3 parameters os,app_name,version name pass in model and get the response in json format.

Step:2 app_version_check() Model

public function app_version_check($os,$app,$version)
{

$this->db->select('*');
$this->db->from('app_info');
$this->db->where('os',$os);
$this->db->where('app_name',$app);
$this->db->where('upgrade_code',$version);
$query=$this->db->get();
return $query->row();


}

Make sure you have a database of app_info table with 3 columns name('os','app_name','upgrade_code').

Now you can test the webservices using Postman.
