How to write a bot of my own

Hello all, I am looking forward to write a bot of my own that will crawl the web and index pages just like other search engines do. But I have no idea where and how to begin. Can anyone give me any input in the matter?

 

If you like to write a personal IM bot, just follow these simple steps:

Step 1: Go to imified.com and request an invite. You should also give your bot a decent name because you can have just one bot per email address.

Step 2. An email with a secret key should arrive in your Inbox the next minute. Copy that key to the clipboard and go here to redeem that key.

Step 3. Now it’s time to create a bot which is actually a simple script that resides on your public web server. It could be in PHP, Perl, Python or any other language. More here.

This is the source of the PHP script I wrote for the labnol IM bot - pretty self explanatory - it reads your message, gets the relevant data from Google Suggest and echoes it back to the IM window.

<?php
// Get all the related keywords from Google Suggest
$u = "http://google.com/complete/search?output=toolbar";
$u = $u . "&q=" . $_REQUEST['msg'];

// Using the curl library since dreamhost doesn't allow fopen
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $u);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

$xml = simplexml_load_string(curl_exec($ch));
curl_close($ch);

// Parse the keywords and echo them out to the IM window
$result = $xml->xpath('//@data');
while (list($key, $value) = each($result)) {
echo $value ."<br>";
}
?>Step 4: Once your script is ready, put it somewhere on your web server and copy the full URI to the clipboard.

Now login to your imified account, paste the script URL and add that im bot your friends list. That’s it.

This was a very basic bot but the possibilities are endless.

For instance, you could write a bot that will send an email to all your close friends via a simple IM message. Or you could write one that will does currency conversion. See stuff that is already implemented in this list of most useful Google Talk bots.

 

Thanks again anilagrawal, actually I am completely new to this world of bot and search engines etc. could you plz let me know if there is any tutorial available so that I could know about the concepts in detail and start experiments on my own, moreover ur example is in PHP could you plz write the same in c++ or c# or java...... I would appreciate it. Thanks

 

Anil Agrawal - you have copied my article and published it here without permission. Very poor approach.
