How to access the raw query string (or full URL) in a Chalice (AWS Lambda/API Gateway) app?

问题

I'm using Chalice to build a fairly straightforward API on AWS Lambda & API Gateway.

I need a way to get access to the raw query string (i.e foo=bar&abc=123). When accessing the app.current_request.query_params dictionary, it's already been processed, such that any empty parameters (foo=&bar=) have been stripped out.

Unfortunately I'm working with a third-party API that sends a signed hash value in the query string, based off the raw query string. I can't verify it without the original, unaltered query string. Is there any way to access it other than current_request.query_params?

回答1:

If you wish to get everything you do the following.

Let's say you are hitting the route /objects/{what}?human=you&thing=computer

@app.route('/objects', methods=['GET'])
def myobject(what):
    everything = app.current_request.to_dict()
    print("look at me: {}".format(params))
