urlencode an array of values
http, python
Solution
The solution is far simpler than the ones listed above.
>>> import urllib
>>> params = {'criterias[]': ['member', 'issue']}
>>>
>>> print urllib.urlencode(params, True)
criterias%5B%5D=member&criterias%5B%5D=issue
Note the True. See http://docs.python.org/library/urllib.html#urllib.urlencode the doseq variable.
As a side note, you do not need the [] for it to work as an array (which is why urllib does not include it). This means that you do not not need to add the [] to all your array keys.
Problem
I'm trying to urlencode an dictionary in python with urllib.urlencode. The problem is, I have to encode an array. The result needs to be: ``` criterias%5B%5D=member&criterias%5B%5D=issue #unquoted: criterias[]=member&criterias[]=issue ``` But the result I get is: ``` criterias=%5B%27member%27%2C+%27issue%27%5D #unquoted: criterias=['member',+'issue'] ``` I have tried several things, but I can't seem to get the right result. ``` import urllib criterias = ['member', 'issue'] params = { 'criterias[]': criterias, } print urllib.urlencode(params) ``` If I use `cgi.parse_qs` to decode a correct query string, I get this as result: ``` {'criterias[]': ['member', 'issue']} ``` But if I encode that result, I get a wrong result back. Is there a way to produce the expected result?
