 1 random.seed(datetime.datetime.now()) 2 def getLinks(articleUrl): 3     html = urlopen("http://en.wikipedia.org"+articleUrl) 4     bsOdj = BeautifulSoup(html) 5     return bsOdj.find("div",{"id":"bodyContent"}).findAll("a",href=re.compile("^(/wiki/)((?!:).)*$")) 6 links = getLinks("/wiki/Kevin_Bacon") 7 while len(links) > 0: 8     newArticle = links[random.randint(0,len(links)-1)].attrs["href"] 9     print(newArticle)10     links = getLinks(newArticle)

这是我的源代码,然后报了警告

D:\Anaconda3\lib\site-packages\bs4\__init__.py:181: UserWarning: No parser was explicitly specified, so I‘m using the best available HTML parser for this system ("lxml"). This usually isn‘t a problem, but if you run this code on another system, or in a different virtual environment, it may use a different parser and behave differently.The code that caused this warning is on line 16 of the file D:/ThronePython/Python3 网络数据爬取/BeautifulSoup 爬虫_开始爬取/BeautifulSoup 维基百科六度分割_构建从一个页面到另一个页面的爬虫.py. To get rid of this warning, change code that looks like this: BeautifulSoup([your markup])to this: BeautifulSoup([your markup], "lxml")  markup_type=markup_type))

百度后发现,其实这是没有设置默认的解析器造成的,

根据提示设置解析器即可,否则则采取默认的解析器,将第四行改为:

    bsOdj = BeautifulSoup(html,"lxml")

即可.
