I cannot use a param that implements FromRequest with a method #get. It works perfectly with a #post
In the code below, the /keyserver/key (GET) works as long as I don't use the header param. Otherwise, I get a :
GET /keyserver/key text/html:
=> Matched: GET /keyserver/key (key_list)
=> Outcome: Forward
=> Error: No matching routes for GET /keyserver/key text/html.
=> Warning: Responding with 404 Not Found catcher.
=> Response succeeded.
How can I get the header information in a GET method?
The /keyserver/add_key (POST) works well with the header param.
