python - 如何在 urlparse 中用新值替换查询？

Question

所以我有一个数据如下:

 item = '//s780.scene7.com/is/image/forever/301596014_001?hei=98&wid=98'

使用 urlparse 模块。我怎样才能用新的大小替换上面的数据，使其看起来像这样:

  item = '//s780.scene7.com/is/image/forever/301596014_001?hei=360&wid=360'

Answer 1

这是一个根据要求使用 urlparse 的答案:

import urllib
import urlparse

url = '//s780.scene7.com/is/image/forever/301596014_001?hei=98&wid=98'
parts = urlparse.urlparse(url)
query_dict = urlparse.parse_qs(parts.query)  # {'wid': ['98'], 'hei': ['98']}
query_dict['wid'] = '360'
query_dict['hei'] = '360'
new_parts = list(parts)
new_parts[4] = urllib.urlencode(query_dict)
print urlparse.urlunparse(new_parts)
