Python'請求'以錯誤的順序添加參數

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

這告訴我它查看了http://data.alexa.com/data?url=www.google.com&cli=10

哪個網址錯誤，應該是http://data.alexa.com/data?cli=10&url=www.google.com

有人可以幫忙嗎？

Answer 1

字典沒有固定的順序。 如果需要有序參數，則將參數作為一系列(key, value)對傳遞：

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

你也應該離開? 從URL， requests將為您處理。

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
<?xml version="1.0" encoding="UTF-8"?>
