Changes to Twitter API

Changes to Twitter API 1.1

As Twitter has changed their API from 1.0 to 1.1 which is totally reliant on oAuth and JSON I have had to take down the links to the Twitter Hash Tag Scanner as it was reliant on the old search RSS feeds which are no longer available.

I have had a quick look but it will take some time to re-develop and involve adding in consumer keys, access keys and so on. You would probably get blocked after a few scans anyway as you would have to login to your own twitter account to make the scans and their rate limits would apply.

Therefore I don't think a new version will be forthcoming to anyone who has purchased a previous version I can only apologise. It's a shame as I wanted to extend it but if I cannot make thousands of scans without being blocked the application just won't work with Twitters new API.

As for the Strictly TweetBot Wordpress plugin I have updated this to use the new API and I have tested it on a couple of my own blogs and it seems to be working.

Today was the switch off day so if you were using the plugin you would have noticed either:
  • No tweets being sent out when you posted.
  • In the Twitter message console lots of error messages saying Tweet not sent or Authentication error.
However if you upgrade to version 1.1.3 then this should fix the problem. 

You can get the latest version from Wordpress.

Also I am pissed off!

And I only just wrote a Twitter Direct Message Responder in PHP the other day which was working fine up until tonight as well!

Damn bloody Twitter.

Even with me being logged in and authenticated I was trying to get a list of my followers and for some reason I kept getting a message like this:

{"errors":[{"message":"Bad Authentication data","code":215}]}

I did write a post to the developer discussion boards on Twitter but as always I have cracked the problem before I got a response.

Basically I am using a very common Twitter / oAuth class which is used by my Twitter Plugin and many other plugins use it as well.

To fix the problem I had to do the following:

Change line 29 in the Twitter class to:

 /* Set up the API root URL. */
 public $host = "https://api.twitter.com/1.1/";


This resolved the issues in my own wordpress plugins which solved sending normal tweets out but to get my Direct Message Responder code working I needed to do one more thing.

Whereras before I was making use of a simple file_get_contents call to an XML feed which Twitter has now abandoned for JSON I had to change this to use the inbuilt HTTP request functions in the Twitter class e.g

$response = $oauth->get($followers_url);

This returns 20 of your new followers (I have not worked out how to get more yet) but in a JSON object.

You can either loop through the nested objects of you could use json_encode to convert the object to a string to do a simple regex to just get a list of screen_names e.g

$body = json_encode($response);

preg_match_all('@"screen_name":"([\s\S]+?)",@i',$body,$matches,PREG_SET_ORDER);

And that solved the problem!

You just need to go to the Twitter developer site and you find loads of information about getting various timelines and twitter feeds.

Remember they are all in JSON now - they have stopped all support for XML, RSS, ATOM.
