----------------------------------------
I understand that diverging ideas without clear needs isn't good at this
moment. Meanwhile, at least there is a need that a user occasionally wants to
use RAW values like {{foo)&+bar}} in the URI, so let's go back and stick to
this original request and support RAW{} syntax to solve it. A pull req will
follow soon.
While working on the fix, I learned the current limitations (including my fix)
of RAW syntax handling in Camel. Let me write them down here:
Currently Camel supports RAW() syntax in two parts of the endpoint URI: 1)
query part and 2) host/path part.
# Query part: e.g. {{?password=RAW(p+?%w0rd)&username=scott}}
** In this part almost every character is allowed, including ')' and '}'. If
you want to use ')&' or '}&' inside RAW then use the other brackets, i.e.
RAW{..} for ')&' and RAW(..) for '}&'.
** RAW can be used only in the value of a query. A key cannot be notated with
RAW. If you use RAW in value, use it entirely. Partial usage such as
{{password=RAW(%%%)bar&...}} is not allowed.
** Implementation details: The query scanner detects the occurrence of ')&' or
'}&' as the closing of each RAW token.
# Host/path part: e.g. {{mock:RAW(se+ret)+language:xpath:/order/@uri}}
** I don't know when it's useful but for some components usages of RAW syntax
in the URI are allowed (e.g. mock component).
** However, unlike the query part, it's not possible to use RAW(foo)bar) or
RAW{foo}bar} in this part. It's still possible to use RAW(foo}bar) and
RAW{foo)bar} though.
** Implementation details: This is because the scanner cannot rely on ')&' or
'}&' for the closing mark in host/path part and thus picks up the first
occurrence of the closing bracket as the closing.
> Add support for alternative RAW() syntax

> Key: CAMEL-12982
> URL: https://issues.apache.org/jira/browse/CAMEL-12982
> Project: Camel
> Issue Type: New Feature
> Components: camel-core
> Reporter: Claus Ibsen
> Assignee: Tadayoshi Sato
> Priority: Major
> Fix For: 3.0.0, 2.24.0
>
>
> In some edge case you may have a password=foo)+bar which you want to use
> as-is. The + sign gets escaped and therefore you need to use RAW syntax. But
> the closing paranthesis is used the first one. And the parser is not always
> smart enough. But this can be tricky to improve as you can use &a=v as will
> and the parser thinks its a new option etc.
> So instead we should add an alternative syntax such as RAW{} where we use
> curly brackets.
