网络抓取错误消息：“int”对象没有属性“get”

Question

您好 Stack Overflow 贡献者！

我想抓取一个新闻网站的多个页面；它在此步骤中显示错误消息

 response = requests.get(page, headers = user_agent)

错误信息是

AttributeError: 'int' object has no attribute 'get'

代码行是

user_agent = {'user-agent': 'Mozilla/5.0 (Windows NT 10.0; WOW64; Trident/7.0; Touch; rv:11.0) like Gecko'}

#controlling the crawl-rate
start_time = time() 
request = 0

def scrape(url):
    urls = [url + str(x) for x in range(0,10)]
    for page in urls:
        response = requests.get(page, headers = user_agent)   
    print(page)
       

print(scrape('https://nypost.com/search/China+COVID-19/page/'))

更具体地说，这个页面和它旁边的页面是我要抓取的：

https://nypost.com/search/China+COVID-19/page/1/?orderby=relevance

任何帮助将不胜感激！

对我来说，这段代码运行良好。我确实必须将request 放入您的函数中。确保不要将模块 requests 与变量 request 混淆。

from random import randint
from time import sleep, time
from bs4 import BeautifulSoup as bs


user_agent = {'user-agent': 'Mozilla/5.0 (Windows NT 10.0; WOW64; Trident/7.0; Touch; rv:11.0) like Gecko'}

# controlling the crawl-rate
start_time = time() 

def scrape(url):
    request = 0
    urls = [f"{url}{x}" for x in range(0,10)]
    params = {
       "orderby": "relevance",
    }
    for page in urls:
        response = requests.get(url=page,
                                headers=user_agent,
                                params=params)   

        #pause the loop
        sleep(randint(8,15))

        #monitor the requests
        request += 1
        elapsed_time = time() - start_time
        print('Request:{}; Frequency: {} request/s'.format(request, request/elapsed_time))
#         clear_output(wait = True)

        #throw a warning for non-200 status codes
        if response.status_code != 200:
            warn('Request: {}; Status code: {}'.format(request, response.status_code))

        #Break the loop if the number of requests is greater than expected
        if request > 72:
            warn('Number of request was greater than expected.')
            break

        #parse the content
        soup_page = bs(response.text, 'lxml') 
        
print(scrape('https://nypost.com/search/China+COVID-19/page/'))
