我才刚刚开始学习如何使用BeautifulSoup进行网络抓取,并想编写一个简单的程序,该程序将通过Instagram中的FullName获取我的偶像的个人资料链接(instagram网址)。
示例:我在文件fullname.txt中存储了FullName列表,如下所示:
#cat fullname.txt
Cristiano Ronaldo
David Beckham
Michael Jackson
我的结果愿望是:
https://www.instagram.com/cristiano/
https://www.instagram.com/davidbeckham/
https://www.instagram.com/michaeljackson/
能给我一些建议吗?

这适用于所有3个名称,另外一些我添加到fullname.txt
它使用请求库和Bing搜索来查找正确的链接,然后使用正则表达式从返回的数据包中解析出该链接。
import requests, re
def bingsearch(searchfor):
link = 'https://www.bing.com/search?q={}&ia=web'.format(searchfor)
ua = {'User-Agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_8_2) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/27.0.1453.116 Safari/537.36'}
payload = {'q': searchfor}
response = requests.get(link, headers=ua, params=payload)
try:
found = re.search('Search Results(.+?)</a>', response.text).group(1)
iglink = re.search('a href="(.+?)"', found).group(1)
except AttributeError:
iglink = "link not found"
return iglink
with open("fullname.txt", "r") as f:
names = f.readlines()
for name in names:
name = name.strip().replace(" ", "+")
searchterm = name + "+instagram"
IGLink = bingsearch(searchterm)
print(IGLink)
