Posting to Tumblr with php & Tumblr API

Question

I am trying to post messages automatically to my Tumblr Blog (which will run daily via Cron)

I am using the Official Tumblr PHP library here: https://github.com/tumblr/tumblr.php

And using the Authentication method detailed here : https://github.com/tumblr/tumblr.php/wiki/Authentication (or parts of this, as i dont need user input!)

I have the below code

require_once('vendor/autoload.php');

// some variables that will be pretttty useful
$consumerKey = 'MY-CONSUMER-KEY';
$consumerSecret = 'MY-CONSUMER-SECRET';
$client = new Tumblr\API\Client($consumerKey, $consumerSecret);
$requestHandler = $client->getRequestHandler();
$blogName = 'MY-BLOG-NAME';
$requestHandler->setBaseUrl('https://www.tumblr.com/');

// start the old gal up
$resp = $requestHandler->request('POST', 'oauth/request_token', array());

// get the oauth_token
$out = $result = $resp->body;
$data = array();
parse_str($out, $data);

// set the token
$client->setToken($data['oauth_token'], $data['oauth_token_secret']);

// change the baseURL so that we can use the desired Methods
$client->getRequestHandler()->setBaseUrl('http://api.tumblr.com');

// build the $postData into an array
$postData = array('title' => 'test title', 'body' => 'test body');

// call the creatPost function to post the $postData
$client->createPost($blogName, $postData);

However this give me the following error:

Fatal error: Uncaught Tumblr\API\RequestException: [401]: Not Authorized thrown in /home///*/vendor/tumblr/tumblr/lib/Tumblr/API/Client.php on line 426

I can retrieve blog posts and other data fine with (example):

echo '<pre>';
print_r( $client->getBlogPosts($blogName, $options = null) );
echo '</pre>';

So it seems it is just making a post that i cant manage.

In all honesty, i dont really understand the oauth Authentication, so am using code that more worthy coders have kindly provided free :-) I assume i am OK to have edited out parts of the https://github.com/tumblr/tumblr.php/wiki/Authentication as i dont need user input as this is just going to be code ran direct from my server (via Cron)

I have spent days looking around the internet for some answers (have gotten a little further), but am totally stuck on this one...

Any advice is much appreciated!

Answer 1

It looks like the parts that you removed in the code pertained to a portion of the OAuth process that was necessary for the desired action.

// exchange the verifier for the keys

You might try running the Authentication Example itself and removing the parts of the code that you've removed until it no longer works. This will narrow down what's causing the issue. I'm not very familiar with OAuth personally, but this looks as though it would be apart of the problem as one of the main portions you took out was surrounding the OAuth process exchanging the verifier for the OAuth keys.
