Dear List, e-Greetings, i'm a PHP developer, and I'm very new to the world of Python and Twisted. When it comes to use Twisted, my mind is unable to go beyond the Top-To-Down Code execution model of PHP... Help!
i've been asked to write a service to process a list of SMS-messages, and send each person a response. The messages are located on a PostgreSQL database at a remote server. Inside an infitie loop in Python, I call a single URL every 5 seconds, which gives me an array of messages in JSON format. This URL has a special format, which a parameter, named "last_sms_id". URL: /give_me_messages.php?last_sms_id=XXX In the Python script, I set a value to this paramter to tell the Remote Script to only give me new messages, and ignore the old ones which I have already recieved. It means that I must update last_sms_id after processing each message. The URL finally returns an array of messages. i'm responsbile to process this array, and based on contents of each message, call a new URL, which doesn't matter for now. Now I'm asked to use Twisted to make my python script asynchronous. Well, I was PHP Programmer. I'm wondering how this application could become asynchronous. Let me explain. If the first call to the above URL fails to recieve content for some reason, what will happen? Does asynchronous mean that Python will invoke a new URL to the same URL again? or It will make a new URL call? How can I handle "last_sms_id" during these asynchronous calls?
