Python's webbrowser module supports some operations on the browser, which is a relatively basic knowledge point for crawlers.

The webbrowser module provides an interface to the system's standard web browser. It provides an open function, which accepts a file name or URL as a parameter, and then opens it in the browser.

method:

1. There are three main methods:

• webbrowser.open(url, new=0, autoraise=True)；
• webbrowser.open_new(url)；
• webbrowser.open_new_tab(url)；

import webbrowser
import time

webbrowser.open("http://www.baidu.com")

# wait a while, and then go to another page
time.sleep(5)

webbrowser.open("http://www.taobao.com")

Use a timed task to write a demo to open and close the webpage: (set response timeout = 5s, hold time after opening = 10s)

# Import the required modules
import webbrowser
import time
import requests
import os

 # 1. Define the URL of the web page to be opened
url = 'https://blog.csdn.net/weixin_44259720/'

 # 2. Determine whether the web address is valid
r = requests.get(url, timeout=5)
result = r.status_code

 # 3. Open the web page if the web address is valid
if (result == 200):
         # 4. Open the browser
    webbrowser.open(url)
    print("Open Success",url)
    time.sleep(10)
         # 5. Close the browser
    os.system('taskkill /F /IM Iexplore.exe')

Close the browser command, and use different commands with different browsers:

• Using Internet Explorer, the command is:os.system('taskkill /F /IM Iexplore.exe')；
• Using the Chrome browser, the command is:os.system('taskkill /F /IM chrome.exe')。

2. Open the designated browser object

• web.get(name): Get the opened browser object, name is the name of the browser, if the name is empty, the default browser will be opened;

Note: directly using web.get(name) to open the browser will report an error, because the browser object needs to be registered first: web.register()

# My local chrome browser clerical job
chromepath = 'C:\Users\xxx\AppData\Local\Google\Chrome\Application\chrome.exe'
 # Register browser object
webbrowser.register('chrome', None, webbrowser.BackgroundBrowser(chromepath))
 # Open the browser
webbrowser.get('chrome').open_new_tab('www.baidu.com')
