用Python URL Parse Parse qs解析URL

Question

这在Python2.7中有效，但在3.5中无效

我正在尝试分割一个url的参数，然后用一个新值（md5散列）更改其中一个参数。

URL就这样崩溃了

ParseResult(scheme='http', netloc='example.com', path='/dynamic', params='', query='t=MD5-YOUR-OAUTH-TOKEN&p=11111111', fragment='')

新的url应该是这样的

newString = 'http://example.com/dynamic?t='+tokenHashed+'&p=11112311312'

import requests, json, hashlib
import urllib
from urllib.parse import urlparse
from xml.etree import ElementTree

        product_url = item.find('product_url').text
        parsed = urlparse(product_url)
        qs = urlparse.parse.parse_qs(parsed.query)
        qs['t'] = [tokenHashed]
        newqs = urllib.urlencode(qs, doseq=1)
        newurl = urlparse.urlunparse([newqs if i == 4 else x for i,x in enumerate(parsed)])



 print(newurl)

我知道这个错误

'function' object has no attribute 'parse'

我的python版本有问题吗？

Answer 1

我也有同样的问题：

from urllib.parse import urlparse
from urllib.parse import parse_qs

product_url = item.find('product_url').text
parsed = urlparse(product_url)
qs = parse_qs(parsed.query)

Answer 2

使用from urlparse import urlparse。或者如果要保存与python 2的兼容性：

try:
    from urllib.parse import urlparse
except ImportError:
    from urlparse import urlparse

更新： 我没注意到。尝试在qs = urllib.parse.parse_qs(parsed.query)上更改qs = urlparse.parse.parse_qs(parsed.query)。
