怪异的行为运行的代码通过功能

Question

我有一个函数从维基媒体API获取文章的文本

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 

但是当我调用该函数，出现错误：

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:

bject at 0x7f7a5e74c0b8>: Failed to establish a new connection: [Errno 
-2] Name or service not known',)) 

首先，我以为我是由维基媒体呼叫太多的请求被阻止，但是当我在“主功能”中运行该代码时，它完全像这样工作。

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怪异的行为，我试图通过Visual Studio代码和response变量get_content功能调试转向undefined。那么有人对这种情况有任何解决方法？

Answer 1

你的函数声明：

def get_content(lang, title): 

但我在你的回溯看到：

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

我相当肯定，有没有这样的网站作为https://Mesut Özil.wikipedia.org
