John Yin commented on CXF-8629:
-------------------------------
I tested this with the latest 4.1.0 release. After varying different factors,
I think the duplicate response issue occurs when 1) the hc5 jar is in the
classpath, and 2) when AutoRedirect="true" is specified in the conduit (even
when the server did not suggest to redirect). Since I only use CXF from Camel,
here is my test script (groovy) using Camel:
{quote}from("timer://testRoute2?repeatCount=1")
// send a http POST to server, and print out the response
.process({
it.in.setBody('\{"name":"john"}')
it.in.setHeader('cache-control', 'no-cache')
it.in.setHeader('Content-Type', 'application/json')
it.in.setHeader('CamelHttpMethod', 'POST')
})
.setExchangePattern(ExchangePattern.InOut)
.to("cxfrs:bean:rsClientTest")
.log('response received: $simple\{body}')
from("cxfrs:bean:rsServerTest?bindingStyle=SimpleConsumer") // receive HTTP
request, printout the request, and send back a response
.log('request received: $simple\{body}')
.process ({
it.in.setHeader('Content-Type', 'application/json')
it.in.setBody('\{"result":"ok"}')
}){quote}
This will produce the following output (when hc5 is used and
AutoRedirect="true" is specified in the conduit. The response from server is
received or processed twice by the client, one had payload, one did not.
