Question

import requests

endpoint = 'http://data.alexa.com/data?'
qparams = {'cli': 10,
           'url': 'www.google.com'}
response = requests.get(endpoint, params=qparams)

print response.url

这告诉我它看了http://data.alexa.com/data?url=www.google.com&cli=10

哪个网址错误，应为http://data.alexa.com/data?cli=10&url=www.google.com

有人可以帮忙吗？

Answer 1

词典有没有固定顺序。如果您需要有序参数，请将参数作为(key, value)对序列传递：

qparams = (
    ('cli', 10),
    ('url', 'www.google.com'),
)

您还应该从网址?开始，requests将为您处理。

演示：

>>> import requests
>>> endpoint = 'http://data.alexa.com/data'
>>> qparams = (
...     ('cli', 10),
...     ('url', 'www.google.com'),
... )
>>> response = requests.get(endpoint, params=qparams)
>>> response.url
u'http://data.alexa.com/data?cli=10&url=www.google.com'
>>> print response.content
