Jan Bednar closed CAMEL-13922.
------------------------------
Resolution: Invalid
Please read that section in documentation again. You are missing *simple* after
*enrich*.
Feel free to ask on mailing list, if following code will not work.
{code:java}
.enrich()
.simple("http4:${header.calendar-uri}")
.aggregationStrategy((oldExchange, newExchange) -> {
oldExchange.getIn().setBody(newExchange.getIn().getBody());
return oldExchange;
})
{code}
> http4 does not recognize part of URI provided with header

> Issue Type: Bug
> Components: camel-http4
> Affects Versions: 2.24.1
> Reporter: Vyacheslav Boyko
> Priority: Major

> I'm trying to describe a route with Enrich EIP. It should be done as:
> 1) template producer gives an year (2019, 2012 etc), set it in header and
> push the message into route
> 2) from that endpoint message should be enriched from URI composed by
> template:
> {code:java}
> from("seda:calendar-update-process")
> .setHeader("calendar-uri",
> simple("xmlcalendar.ru/data/ru/${header["+HEADER_YEAR+"]}/calendar.xml"))
> .log(LoggingLevel.WARN, log, "Updating calendar from url:
> ${header.calendar-uri}")
> .enrich("http4:$\\{header.calendar-uri\\}", (oldExchange,
> newExchange) -> {
> oldExchange.getIn().setBody(newExchange.getIn().getBody());
> return oldExchange;
> })
> {code}
> {color:#6a8759}{color}{color:#6a8759}as described on{color}
> [https://camel.apache.org/manual/latest/content-enricher.html] in part named
> 'Using dynamic uris'

> But it cannot parse that expression. I get an error:
