我正在使用 Tweepy 和 BeautifulSoup4 構建 Twitter 機器人。我想將請求的結果保存在列表中，但我的腳本不再工作（但幾天前就可以工作）。我一直在看，但我不明白。這是我的功能：import requestsimport tweepyfrom bs4 import BeautifulSoupimport urllibimport osfrom tweepy import StreamListenerfrom TwitterEngine import TwitterEnginefrom ConfigEngine import TwitterAPIConfigimport urllib.requestimport emojiimport random# desktop user-agentUSER_AGENT = "Mozilla/5.0 (Macintosh; Intel Mac OS X 10.14; rv:65.0) Gecko/20100101 Firefox/65.0"# mobile user-agentMOBILE_USER_AGENT = "Mozilla/5.0 (Linux; Android 7.0; SM-G930V Build/NRD90M) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/59.0.3071.125 Mobile Safari/537.36"# Récupération des liensdef parseLinks(url): headers = {"user-agent": USER_AGENT} resp = requests.get(url, headers=headers) if resp.status_code == 200: soup = BeautifulSoup(resp.content, "html.parser") results = [] for g in soup.find_all('div', class_='r'): anchors = g.find_all('a') if anchors: link = anchors[0]['href'] results.append(link) return results代碼其余部分中的“url”參數 100% 正確。作為輸出，我得到“無”。更準確地說，執行在“results = []”行之后立即停止（因此它不會進入 for）。任何想法？提前非常感謝！

Google 似乎更改了頁面上的 HTML 標記。嘗試將搜索從更改class="r"為class="rc"：
import requests
from bs4 import BeautifulSoup
USER_AGENT = "Mozilla/5.0 (Macintosh; Intel Mac OS X 10.14; rv:65.0) Gecko/20100101 Firefox/65.0"
def parseLinks(url):
headers = {"user-agent": USER_AGENT}
resp = requests.get(url, headers=headers)
if resp.status_code == 200:
soup = BeautifulSoup(resp.content, "html.parser")
results = []
for g in soup.find_all('div', class_='rc'): # <-- change 'r' to 'rc'
anchors = g.find_all('a')
if anchors:
link = anchors[0]['href']
results.append(link)
return results
url = 'https://www.google.com/search?q=tree'
print(parseLinks(url))
