遞迴遍歷網站所有 url

想寫一個指令碼，遍歷帶有域名的url，檢查狀態碼是否有異常。遇到一個問題，requests返回的內容裡面沒有a標籤。
網頁的內容都在這個div裡面，但是requests返回的資料裡面為空

import requests
from bs4 import BeautifulSoup

headers = {
    "user-agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/86.0.4240.111 Safari/537.36",
}
resource_list = list()


def get_urls(url):
    r = requests.get(url)
    print(url)
    print(r.text)
    soup = BeautifulSoup(r.text, 'html.parser')
    urls = soup.find_all("a")
    if not urls:
        return
    if urls:
        for i in urls:
            try:
                if i['href'] not in resource_list:
                    status_code = requests.get(i['href']).status_code
                    if status_code not in (200, 0):  # code 不對則列印出來
                        print(i['href'], status_code)

                    if "https://www.mxc.ai/" in i['href']:  # 判斷是否含有域名
                        resource_list.append(i['href'])
                        get_urls(i['href'])
            except Exception:
                pass


get_urls("https://www.mxc.ai/")
