Python is a remarkably powerful dynamic programming language that is used in a wide variety of application domains. Python is often compared to Tcl, Perl, Ruby, Scheme or Java. The Python support is part of the
camel-script
module.

To use Python in your routes you need to add a dependency on
camel-script
to your project as shown in Example 24.1, “Adding the camel-script dependency”.

import static org.apache.camel.builder.camel.script.ScriptBuilder.*;

request | org.apache.camel.Message | The IN message |
response | org.apache.camel.Message | The OUT message |
properties | org.apache.camel.builder.script.PropertiesFunction | Function with a resolve method to make it easier to use the properties component inside scripts. |

To access a property value from the properties component, invoke the
resolve
method on the built-in properties
attribute, as follows:
.setHeader("myHeader").python("properties.resolve(PropKey)")
.setHeader("myHeader").python("properties.resolve(PropKey)")
Where PropKey is the key of the property you want to resolve, where the key value is of
String
type.
