The keyword specifies how option works when specified multiple times: - single: the last provided value replaces the earlier ones - append: it supports being provided multiple times - boolean: on/off values - mutex: flag-like option that disable anoter flag The 'gen.pl' script then outputs the proper and unified language for each option's multi-use behavior in the generated man page. The multi: header is requires in each .d file and will cause build error if missing or set to an unknown value. Closes #9759

Sends the specified JSON data in a POST request to the HTTP server. --json
|
|
works as a shortcut for passing on these three options:
|
|
|
|
--data [arg]
|
|
--header "Content-Type: application/json"
|
|
--header "Accept: application/json"
|
|
|
|
There is **no verification** that the passed in data is actual JSON or that
|
|
the syntax is correct.
|
|
|
|
If you start the data with the letter @, the rest should be a file name to
|
|
read the data from, or a single dash (-) if you want curl to read the data
|
|
from stdin. Posting data from a file named 'foobar' would thus be done with
|
|
--json @foobar and to instead read the data from stdin, use --json @-.
|
|
|
|
If this option is used more than once on the same command line, the additional
|
|
data pieces will be concatenated to the previous before sending.
|
|
|
|
The headers this option sets can be overridden with --header as usual.
