问题
I know in php I could just use $_GET['key1']['key2'] to retrieve GET data that is sent in the form of an array but is that something possible in Python as I just receive a string and it's not recognized as an array/list.
I use flask/werkzeug if that matters.
回答1:
The deep parsing of argument names is unique for PHP AFAIK.
If you need just a simple list, just pass several parameters with the same name and use request.args.getlist(<paramname>) (documentation).
Otherwise you have to parse the query string yourself.
回答2:
request.args is a MultiDict instance (MultiDict, Flask request api).
request.args[key] ## returns a single value, the first if there are multiple
request.args.getlist(key) ## returns a list
If you want to submit structures more complex than can be encoded using simple key:vals, consider sending a json encoded object.
Also, look at the jQuery recursive param serialisation pattern, and the jquery-unparam lib which can deserialise it.
