奇怪的行为 运行 代码通过函数

Question

我有一个从维基媒体获取文章文本的功能api

def get_content(lang, title):
    url = "https://"+ lang +".wikipedia.org/w/api.php"
    params={'action':'query', 'format':'json', 'titles': title, 'prop': 
        'linkshere','redirects':'true','prop':'extracts','exlimit':'max','explaintext':'true'}
    response = requests.get(url=url,params=params).json()
    content = response["query"]["pages"]
    content = six.next(six.itervalues(content))['extract']
    return content

但是当我调用这个函数时，出现了错误：

Traceback (most recent call last):
File "/home/klux/anaconda3/lib/python3.5/site-
packages/requests/adapters.py", line 423, in send

During handling of the above exception, another exception occurred:

首先，我以为我是因为调用了太多请求而被维基媒体屏蔽了，但是当我 运行 在 "main function" 中编写该代码时，它就像这样完美地工作。

if __name__ == '__main__':
    lang = 'en'
    title = 'Mesut Özil'
    url = "https://"+ lang +".wikipedia.org/w/api.php"
    params={'action':'query', 'format':'json', 'titles': title, 'prop': 'linkshere',
            'redirects':'true','prop':'extracts','exlimit':'max','explaintext':'true'}
    response = requests.get(url=url, params=params).json()
    content = response["query"]["pages"]
    content = six.next(six.itervalues(content))['extract']
    print(content)

输出：

Mesut Özil (German pronunciation: [ˈmeːzut ˈøːzil], Turkish: [meˈsut 
ˈøzil]; born 15 October 1988) is a German fo
otballer who plays for English club Arsenal and the German national 
team...

我不知道如何解决这个奇怪的行为，我尝试通过 visual studio 代码和 get_content 函数中的 response 变量进行调试转向 undefined。那么有人对这种情况有什么解决办法吗？

Answer 1

您的函数已声明：

def get_content(lang, title):

但我在你的回溯中看到：

print(get_content('Mesut Özil','en'))

我很确定没有 https://Mesut Özil.wikipedia.org

这样的网站
