this is dumb:
- make a string with the taxonomy slug
- make an object with the post type and any other parameters you want to request
- add the term to the request object, with the string from step 1 as the key
3 steps to build the request because someone at automatic decided to use dashes in the wordpress.com portfolio taxonomy. I suppose I could equally blame Angular for auto-unwrapping dashes in object keys. Although there is a second error in wordpress’ architecture, of requiring the term in such a strange GET parameter, instead of in JSON in the request body.
