首先要获取网页的代码，先将其装成一个函数
def getHTMLText(url): try: r = requests.get(url, timeout = 30) r.raise_for_status() #r.encoding = ‘utf-8‘ return r.text except: return ""
在chrome浏览器下，直接进去新闻之后，右键题目检查就可以定位到题目所在的html代码，如下图
然后会看到<h1>标签内，它的上一级标签是div，并且class="hd"，BeautifulSoup提供了一个CSS选择器，直接调用select方法即可
所以代码可以写成
def getContent(url): html = getHTMLText(url) # print(html) soup = BeautifulSoup(html, "html.parser") title = soup.select("div.hd > h1") print(title[0].get_text()) time = soup.select("div.a_Info > span.a_time") print(time[0].string) author = soup.select("div.qq_articleFt > div.qq_toolWrap > div.qq_editor") print(author[0].get_text()) paras = soup.select("div.Cnt-Main-Article-QQ > p.text") for para in paras: if len(para) > 0: print(para.get_text()) print()
