Apologies, `application/data` in the commit message's example should be `application/json`, and will need to be updated after review(s) in the final commit. On Fri, Jul 3, 2020 at 10:53 AM Kevin Morris <kevr.gtalk@gmail.com> wrote:
When we received a POST method from a client, deduce our `$data` by determining which `Content-Type` is used.
Supported `Content-Type`s =========================
* `application/json` * `multipart/form-data`
`application/json` POST Example, searching for 'test': ``` curl -X POST -H 'Content-Type: application/data' \ --data '{"v": "5", "type": "search", "arg": "test"}' \ https://aur.archlinux.org/rpc/ ```
`multipart/form-data` POST Example, search for 'test': ``` curl -X POST -H 'Content-Type: multipart/form-data' \ -F v=5 -F type=search -F arg=test \ https://aur.archlinux.org/rpc/ ```
This change was written as a solution to https://bugs.archlinux.org/task/49089.
NOTE: This commit is not final; would like a review and a bit more consideration on `multipart/form-data` and ensuring that we're handling everything we need to.
