Is there a way to access the response body before sending the response back?
You could write a simple plugin, which (depending on what you're actually trying to do with the response) might be all you need.
Here's an example from the Bottle plugin docs, which sets a request header. It could just as easily manipulate body
.
from bottle import response, install
import time
def stopwatch(callback):
def wrapper(*args, **kwargs):
start = time.time()
body = callback(*args, **kwargs)
end = time.time()
response.headers['X-Exec-Time'] = str(end - start)
return body
return wrapper
install(stopwatch)
Hope that works for your purposes.
