Table of Contents
Prototype: validdata(data_container, type)
Return type: boolean
Description: Validates a JSON container from data_container
and returns
true
if the contents are valid JSON.
This function is intended to be expanded with functionality for validating
CSV and YAML files eventually, mirroring readdata()
. If type
is JSON
,
it behaves the same as validjson()
.
Arguments:
data_container
:string
, in the range:.*
type
: one ofJSON
Example:
Run:
bundle agent main
{
vars:
"json_string" string => '{"test": [1, 2, 3]}';
reports:
"This JSON string is valid!"
if => validdata("$(json_string)", "JSON");
"This JSON string is not valid."
unless => validdata("$(json_string)", "JSON");
}
Output:
R: This JSON string is valid!
