Bruno Meseguer created CAMEL-21928:
--------------------------------------
Summary: include variable() and body() as new functions to access
in-process data
Key: CAMEL-21928
URL: https://issues.apache.org/jira/browse/CAMEL-21928
Project: Camel
Issue Type: Improvement
Components: camel-jq
Reporter: Bruno Meseguer
According to the documentation here:
*
[https://camel.apache.org/components/next/languages/jq-language.html#_camel_supplied_jq_functions]
The Camel JQ component includes functions to access:
* headers
* properties
However, now Camel includes variables, which is the recommended way to keep
process data in context.
As variables are not supported, users are obligated to set headers or
properties in order to access in-process data.
Another desirable function to have is 'body()'. At first, it seems unnecessary
because a JQ expression would operate against the message body by default.
However, you might want to define the expression to use a variable as the
source, and then need to access the body (not possible at the moment).
To illustrate the need, see the YAML below, where you might want to use JQ to
modify a variable, and use data from the body like this:
{code:java}
- setVariable:
name: mydata
expression:
jq:
source: mydata
expression: '. + [{"response1": body()}]'{code}
For clarity, the code above reads the variable "mydata" that contains a JSON
array, the expression adds a new entry "response1" with the value from the body.
To summarise the need, please include:
* new function {*}variable(){*}, for example to do variable("mydata")
* new function *body()*
