# `--json`
|
|
|
|
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 filename 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 are concatenated to the previous before sending.
|
|
|
|
The headers this option sets can be overridden with --header as usual.
