如何使用Python在Google中搜索请求

Question

我试着运行代码here。

但是，我发出以下消息。

我错过了一些参数吗？

使用requests进行搜索的正确方法应该是什么？

非常感谢你。

import requests 
from bs4 import BeautifulSoup

def google(q):
    s = requests.Session()
    q = '+'.join(q.split())
    url = 'https://www.google.com/search?q=' + q + '&ie=utf-8&oe=utf-8'
    r = s.get(url, headers=headers_Get)
    return r.text

result = google('"apple"')

我正在将它用于Google并且它有效：

import requests
from urllib.request import Request, urlopen
import urllib
from bs4 import BeautifulSoup

headers = {"User-Agent":"Mozilla/5.0 (Macintosh; Intel Mac OS X 10_9_5) AppleWebKit 
537.36 (KHTML, like Gecko) Chrome",
"Accept":"text/html,application/xhtml+xml,application/xml; 
q=0.9,image/webp,*/*;q=0.8"}

def google(q):
    q = '+'.join(q.split())
    url = 'https://www.google.com/search?q=' + q + '&ie=utf-8&oe=utf-8'
    reqest = Request(url,headers=headers)
    page = urlopen(reqest)
    soup = BeautifulSoup(page)
    return r.text
