I've just begun my journey into the realms of the CherryPy module in Python. It's pretty awesome how easy it makes it to setup a server with a RESTful api, however I've ran into an issue. My code is only acknowledging the first parameter in a query string.
I want to make a GET request like so:
curl -X GET 127.0.0.1:8080/api/sum/?a=2&b=3
My Python code is as follows:
import cherrypy
class getSum:
exposed = True
def GET(self, **params):
a = float(params['a'])
b = float(params['b'])
return a+b
if __name__ == '__main__':
cherrypy.tree.mount(getSum(), '/api/sum/', {'/': {'request.dispatch': cherrypy.dispatch.MethodDispatcher()}})
cherrypy.engine.start()
cherrypy.engine.block()
After fiddling with the code for a while I've come to the following diagnosis:
When the query string is being read into params, instead of starting a new entry in the dictionary when it reaches the '&' it just stops instead.
Has anyone got any advice on how to read multiple parameters in as a single query string?
With Thanks, Sean.
The Python script posted in my question is actually a working implementation of what I wanted to do. The problem was instead with the curl request that I was making.
The '&' character in my curl request was truncating my bash command, resulting in this: curl -X GET 127.0.0.1:8080/api/sum/?a=2
The fix for this is to wrap my url in quotes like so: curl -X GET "127.0.0.1:8080/api/sum/?a=2&b=3"
When executing this command 5.0 is returned to the terminal, as expected.
