urlencode一组值 [英] urlencode an array of values

问题描述

我正在尝试使用urllib.urlencode对python中的字典进行urlencode。问题是，我必须编码一个数组。

I'm trying to urlencode an dictionary in python with urllib.urlencode. The problem is, I have to encode an array.

结果必须是：

criterias%5B%5D=member&criterias%5B%5D=issue
#unquoted: criterias[]=member&criterias[]=issue

但我得到的结果是：

criterias=%5B%27member%27%2C+%27issue%27%5D
#unquoted: criterias=['member',+'issue']

我尝试了几件事，但似乎无法得到正确的结果。

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)

如果我使用 cgi.parse_qs 解码一个正确的查询字符串，我得到这个结果：

If I use cgi.parse_qs to decode a correct query string, I get this as result:

{'criterias[]': ['member', 'issue']}

但如果我对该结果进行编码，则会得到错误的结果背部。有没有办法产生预期的结果？

But if I encode that result, I get a wrong result back. Is there a way to produce the expected result?

推荐答案

解决方案比上面列出的解决方案简单得多。

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

注意True。请参见 http://docs.python.org/library/urllib.html#urllib。 urlencode doseq变量。

Note the True. See http://docs.python.org/library/urllib.html#urllib.urlencode the doseq variable.

作为旁注，你不需要[]使它作为一个数组工作（这就是为什么urllib不包含它）。这意味着您不需要将[]添加到所有数组键中。

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.
