Tim Dudgeon created CAMEL-7582:
----------------------------------
Summary: Python scripts with multiple statements return null
Key: CAMEL-7582
URL: https://issues.apache.org/jira/browse/CAMEL-7582
Project: Camel
Issue Type: Bug
Components: camel-language
Affects Versions: 2.13.0
Reporter: Tim Dudgeon
Priority: Minor
As reported here:
http://camel.465427.n5.nabble.com/Return-Value-from-Python-Script-Not-In-Message-Body-tt5724056.html#none
It seems that when calling python script that has more than a single statement
the return value from the script is null. Here is a simple example in groovy
that shows this:
{code}
package com.im.examples
import org.apache.camel.*
import org.apache.camel.impl.*
import org.apache.camel.builder.*
String script = URLEncoder.encode('"Hello world!"', "UTF-8") // this works -
script returns "Hello world!"
//String script = URLEncoder.encode('bar = "baz"; "Hello world!"', "UTF-8") //
this fails - script returns null
CamelContext camelContext = new DefaultCamelContext()
camelContext.addRoutes(new RouteBuilder() {
def void configure() {
from("direct:python")
.to("language:python:" + script)
}
}
)
camelContext.start()
ProducerTemplate t = camelContext.createProducerTemplate()
def result = t.requestBody('direct:python', 'foo')
println result
camelContext.stop()
{code}
