> Key: CAMEL-18802
> URL: https://issues.apache.org/jira/browse/CAMEL-18802
> Project: Camel
> Issue Type: Improvement
> Components: camel-base64, camel-core
> Reporter: Andrea Cosentino
> Assignee: Claus Ibsen
> Priority: Major
> Fix For: 3.20.0
>
>
> Suppose you have something like:
> {code:java}
> template:
> from:
> uri: "google-storage://{{bucketNameOrArn}}"
> parameters:
> autoCreateBucket: "{{autoCreateBucket}}"
> serviceAccountKey: "base64:{{serviceAccountKey}}"
> deleteAfterRead: "{{deleteAfterRead}}"
> {code}
> and you want to have serviceAccountKey as optional parameter. If you prefix
> the parameter with '?', like
> {code:java}
> template:
> from:
> uri: "google-storage://{{bucketNameOrArn}}"
> parameters:
> autoCreateBucket: "{{autoCreateBucket}}"
> serviceAccountKey: "base64:{{?serviceAccountKey}}"
> deleteAfterRead: "{{deleteAfterRead}}"
> {code}
> We'll try to encode the value anyway, even if not specified.
