Python API courses batch_update, doesn't work for 500 courses
I wrote a Python script to publish a large group of courses at one time using the API for Update courses (https://canvas.instructure.com/doc/api/courses.html#method.courses.batch_update).
What I originally wrote was very similar to Mike Nahmias’ post (https://community.canvaslms.com/message/109721-python-script-to-publish-courses-in-an-account).
However, it only works for about 350 courses while the limit is listed as 500. I get a 414 error back instead of 200, because the URL is too long. Here’s the full error:
<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">
<title>414 Request-URI Too Long</title>
<h1>Request-URI Too Long</h1>
<p>The requested URL's length exceeds the capacity
limit for this server.<br />
<address>Apache Server at canvas.instructure.com Port 80</address>
Like Mike, I was using the “requests.put”:
requests.put(url, headers=headers, params=payload)
So, that explains the error as everything is being put onto the URL and it’s just too long.
However, when I switch it to use post, it no longer works. Instead it creates a new course, as do all of these:
requests.post(url, headers=headers, params=payload)
requests.post(url, headers=headers, json=payload)
requests.post(url, headers=headers, json=json.dumps(payload))
(Thanks to Brian Bennett’s reply and Jason Kocur’s thread for the json ideas, but it doesn’t work for this API.
Has anybody gotten this to work for > 350 courses? And what’s the secret?
I’d be happy to try UCF Open’s canvasapi, but I can’t find this batch update for courses.
