---------------------------------
Resolution: Fixed
> Cannot use square brackets in HTTP parameters
> ---------------------------------------------
>
> Key: CAMEL-17520
> URL: https://issues.apache.org/jira/browse/CAMEL-17520
> Project: Camel
> Issue Type: Bug
> Components: camel-core
> Affects Versions: 3.12.0
> Reporter: Pasquale Congiusti
> Assignee: Claus Ibsen
> Priority: Minor
> Fix For: 3.14.1, 3.15.0
>
>
> It was reported on mailing list, there is some problem when trying to use
> square brackets as part of the URI params. I've run some expertiment with the
> RAW() function, but this is only applied to the value parameter, not the
> variable name (ie, _param=RAW(value)_).
> As a reproducer, we may run this route (ie, via Camel K):
> {code}
> // camel-k: language=java
> import org.apache.camel.builder.RouteBuilder;
> import org.apache.camel.model.rest.RestParamType;
> import org.apache.camel.Exchange;
> public class Test extends RouteBuilder {
> @Override
> public void configure() throws Exception {
> rest()
> .get("/hello")
>
> .param().name("test[bogus]").type(RestParamType.query).defaultValue("false").description("Just
> for testing").endParam()
> .to("direct:hello");
> from("direct:hello")
> .setHeader(Exchange.CONTENT_TYPE, constant("text/plain"))
> .setBody().simple("${headers.test[bogus]}");
> // Write your routes here, for example:
> from("timer:java?period=3000")
> .to("http://localhost:8080/hello?test[bogus]=true";)
> .log("${body}");
> }
> }
> {code}
> It will end up with error:
> {code}
> [1] Caused by: org.apache.camel.ResolveEndpointFailedException: Failed to
> resolve endpoint: http://localhost:8080/hello?test%5Bbogus%5D=true due to:
