Extension:Education Program/ListStudents API

The ListStudents API (available since 2014-05-15) can be used to pull together lists of student usernames (or user IDs).

Usage

 * Create a list of the course IDs for all the courses you want to collect student usernames from. Each ID should be separated by a pipe. You can find the ID of a course from the table at Special:Courses (See example on test2.wikipedia.)
 * Replace test2.wikipedia with the wiki you want to query, and use a url of this form with your course ID list: |3|5|7|9|10|11|12|15 http://test2.wikipedia.org/w/api.php?action=liststudents&courseids=2|3|5|7|9|10|11|12|15
 * You can collect the usernames in a CSV format (one username per line) that can be copy-and-pasted into Wikimetrics by adding the "csv" parameter: |24|32|40|41|45|46|47|48|49|50|51&csv http://test2.wikipedia.org/w/api.php?action=liststudents&courseids=21|24|32|40|41|45|46|47|48|49|50|51&csv
 * You can get the usernames grouped by course (instead of in one long list) by adding the "group" parameter: |3|5|7|9|10|11|12|15|16|17|18|21|24|32|40|41|45|46|47|48|49|50|51&csv&group http://test2.wikipedia.org/w/api.php?action=liststudents&courseids=2|3|5|7|9|10|11|12|15|16|17|18|21|24|32|40|41|45|46|47|48|49|50|51&csv&group
 * You can collect user IDs instead of usernames by adding the "prop=id" parameter: |24|32|40|41|45|46|47|48|49|50|51&csv&group&prop=id http://test2.wikipedia.org/w/api.php?action=liststudents&courseids=21|24|32|40|41|45|46|47|48|49|50|51&csv&group&prop=id

Troubleshooting

 * It seems like the default format of the MediaWiki API has changed from XML to JSON. The above links may not display clearly (especially non Latin character usernames). To remedy this, add &format=xmlfm to the end of your query to manually switch back to XML output. This is much more copy/paste friendly: http://test2.wikipedia.org/w/api.php?action=liststudents&courseids=21|24|32|40|41|45|46|47|48|49|50|51&csv&format=xmlfm
