Python 通过函数运行代码的奇怪行为

我有一个从维基媒体api获取文章文本的函数

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，当我调用此函数时，会出现错误：

Traceback (most recent call last):

packages/requests/adapters.py", line 423, in send

During handling of the above exception, another exception occurred:

输出：

Mesut Özil (German pronunciation: [ˈmeːzut ˈøːzil], Turkish: [meˈsut 
ˈøzil]; born 15 October 1988) is a German fo

我不知道如何解决这个奇怪的行为，我尝试用visual studio代码调试，

get\u content

函数中的

response

变量变为

undefined

。有人能解决这种情况吗？

您的函数声明为：

def get_content(lang, title):

但我在你的回溯中看到：

print(get_content('Mesut Özil','en'))

我相当肯定没有

https://Mesut Özil.wikipedia.org

Opps，这个愚蠢的错误让我头疼，非常感谢。不幸的是，您的代码片段缺少重现或解决问题所需的上下文。在目前的状态下，不可能写出一个建设性的解决方案，因此这个问题对其他读者没有用处。我投票结束这个问题。如果选择改进，问题将自动添加到重新打开队列。有关更多信息，请参阅以下两页：

print(get_content('Mesut Özil','en'))
