PostToTumblr v3.18 – Fixed Tumblr oauth change

head

 

Just a quick update to say I have now fixed the authentication issue my PostToTumblr that quite a few people contacted me about.

What was going on was that Tumblr appear to have changed the format of the data they return from a token request which was causing a library that PostToTumblr relies on to fail.

Before PostToTumblr can post content on a users behalf it first must get an “access token”. This token is given to PostToTumblr as part of the authentication flow.

When PostToTumblr first starts up it checks to see if it still has a valid token (they can expire over time and other various reasons). If it doesnt it must go through the authentication flow. Firstly it redirects the user to the grant permission dialog:

When the user clicks allow Tumblr then returns an “oauth token” and an “oauth verifier” to PostToTumblr, which it can then use to get an “access token” which is used to do the posting.

The problem that this update fixed was that the “oauth verifier” that was returned from Tumblr changed:

You see at the end of the query string there is now a “#_=_” well this was causing havoc with the URL parameter parsing code in the Google oauth library I was using.

My solution is quick and dirty, just strip out the “#_=_” from the url while parsing:

// MIKE HACK!!	  
if(param.indexOf('oauth_verifier=')!=-1) 
{
	param = param.replace('oauth_verifier=','');
	param = param.replace('#_=_','');		  
	decoded['oauth_verifier'] = ChromeExOAuth.fromRfc3986(param);
}
else
{	  	  
	var keyval = param.split("=");
	if (keyval.length == 2) {
		var key = ChromeExOAuth.fromRfc3986(keyval[0]);
		var val = ChromeExOAuth.fromRfc3986(keyval[1]);
		decoded[key] = val;
	}
}

Well I hope this helps anyone else that may encounter this issue too!

Post To Tumblr v3.13

head

Just a quick update to my Chrome Extension PostToTumblr this morning to fix a few things and add a couple of features after the large update in v3.12.

The change log:

- v3.13 -- 20/01/13 
+ More one-click options for post state, tags and caption
+ New button in the options for resetting Tumblr auth
+ New button for formatted posts for posting to draft
+ Fixed it so you no longer have a menu on one-click if you only have one blog
+ Correct verbs are now displayed in the desktop notifications when posting
+ Fixed an issue with white pages if you rename your blog

PostToTumblr v3.12 Update

head

I have finally found some time to do a long overdue update to my popular Chrome extension PostToTumblr built using Haxe. 30,000 people currently have the extension installed and they post about 10,000 images, links, quotes per day so I thought it was about time to give it some love.

The list of improvements are:
+ One-Click posting now available in the options
+ Tall images now no longer appear off the screen
+ Notifications now used instead of popups
+ Improved error detection
+ Improved authorization process

The main feature in the update is the one-click posting. This much-requested feature was available in the original PostToTumblr but for various reasons never made it into the latest reincarnation.

Once enabled in the options it enables the user to bypass the post preformatting window that usually pops up and instead posts with some default settings. If you have more than one blog the post menu gives you the option for which blog you would like the post to go to:

The normal popup “posting..” window has been replaced with HTML5 notifications.

This should make posting a smoother, less intrusive process.

If you haven’t got the extension already you can grab it on the Chrome Store else Chrome should auto-update the extension for you very soon!
