python 爬虫可视化函数，可以先看看要爬取的数据是否存在

import requests

url = "http://www.spbeen.com"

headers = {

    "User-Agent":"teste"

}

response = requests.get(url,headers=headers)

print(response.status_code)

print(response.headers)

print(response.request.headers)

def request_view(response):

    import webbrowser

    request_url = response.url

    base_url = '<head><base href="%s">' %(request_url)

    base_url = base_url.encode()

    content = response.content.replace(b"<head>",base_url)

    tem_html = open('tmp.html','wb')

    tem_html.write(content)

    tem_html.close()

    webbrowser.open_new_tab('tmp.html')

request_view(response)
