从 URL 中检索参数 [英] Retrieving parameters from a URL
问题描述
给定一个像下面这样的 URL,我如何解析查询参数的值?例如,在这种情况下,我想要 some_key
的值.
Given a URL like the following, how can I parse the value of the query parameters? For example, in this case I want the value of some_key
.
/some_path?some_key=some_value'
我在我的环境中使用 Django;request
对象上是否有可以帮助我的方法?
I am using Django in my environment; is there a method on the request
object that could help me?
我尝试使用 self.request.get('some_key')
但它没有像我希望的那样返回值 some_value
.
I tried using self.request.get('some_key')
but it is not returning the value some_value
as I had hoped.

这并非特定于 Django,而是适用于一般的 Python.对于 Django 的特定答案,看到这个来自@jball037
This is not specific to Django, but for Python in general. For a Django specific answer, see this one from @jball037
Python 2:
import urlparse
url = 'https://www.example.com/some_path?some_key=some_value'
parsed = urlparse.urlparse(url)
captured_value = urlparse.parse_qs(parsed.query)['some_key'][0]
print captured_value
Python 3:
from urllib.parse import urlparse
from urllib.parse import parse_qs
url = 'https://www.example.com/some_path?some_key=some_value'
parsed_url = urlparse(url)
captured_value = parse_qs(parsed_url.query)['some_key'][0]
print(captured_value)
parse_qs
返回一个列表.[0]
获取列表的第一项,因此每个脚本的输出为 some_value
parse_qs
returns a list. The [0]
gets the first item of the list so the output of each script is some_value
