-------------------------------------
Summary: Support for multiple request query parameters in Rest
component
Key: CAMEL-14163
URL: https://issues.apache.org/jira/browse/CAMEL-14163
Project: Camel
Issue Type: Improvement
Components: rest
Affects Versions: 2.18.0
Reporter: Zoran Regvart
Assignee: Zoran Regvart
The RestProducer doesn't have a way for specifying multiple query parameters.
Given a header value that's a collection of values the resulting query
parameter will be a joining of those values with the comma separator.
Given that the query parameter can be specified multiple times, it is more
common to have the parameter specified for each value of the collection rather
than a single parameter with the coma-separated list of values.
For example, endpoint URI of {{rest:GET:/v2/:pet/findByStatus}} and endpoint
property {{queryParameters}} set to {{status=\{status\}}}, and on the message
header the {{status}} is a collection or array of values (e.g. {{["available",
"pending"]}}), the resulting URI will be
{{/v2/pet/findByStatus?status=available,pending}}.
I think we could extemd the syntax of the placeholder (the {{\{status\}}}) to
indicate that multiple query parameters should be provided instead of the
coma-separated values.
Perhaps something like {{status=\{status*\}}} as we already have
{{status=\{status?\}}} to signify optional parameters.
