在 Python 中最大化 WebDriver (Selenium 2)

Question

I'm attempting to write a simple script that checks if I have any gmail emails labeled SOMETHING and then opens a firefox browser window to a login page, after which it goes to something else.

Here's what I'm doing:

from selenium import webdriver
from selenium.webdriver.support.ui import WebDriverWait
from selenium.common.exceptions import TimeoutException
from selenium.webdriver.common.action_chains import ActionChains
import time, imaplib

Eusername = "someone@gmail.com"
Epassword = "password1"

username = "username"
password = "password2"

imaps = imaplib.IMAP4_SSL('imap.gmail.com','993')
imaps.login(Eusername,Epassword)

imaps.select('SOMETHING')
status, response = imaps.status('SOMETHING', "(UNSEEN)")
unreadcount = int(response[0].split()[2].strip(').,]'))

while unreadcount > 0:
    driver = webdriver.Firefox()
    driver.get('http://wwww.SomeURL.com/some_login.html')
    time.sleep(3)
    inputElement = driver.find_element_by_name("user")
    inputElement.send_keys(username)
    inputElement = driver.find_element_by_name("pw")
    inputElement.send_keys(password)
    inputElement.submit()
    time.sleep(1)
    driver.get('http://www.SomeURL.com/somethingelse.html')
    imaps.select('SOMETHING')
    typ ,data = imaps.search(None,'UnSeen')
    imaps.store(data[0].replace(' ',','),'+FLAGS','\Seen')

I've spent hours search and haven't found a solution to maximize the browser window. Elsewhere i've read that there is a windowMaximize() or window_maximize(), but have not been able to get them to work since every configuration I've tried claims it doesn't exist for whatever module.

I only know a little python, and am working in Mac OSX

Answer 1

I've never used this functionality before, so I tried it out.

driver.maximize_window()

This seems to work fine - unless I am using Chrome. I'm not sure if this is a defect, as it works flawlessly in IE9 and Firefox.

edit: This is a feature which has yet to be implemented in Chromedriver -= Link to issue =-

edit (8 years later): Apparently this is working in Chrome on Linux and Windows - so, yay! I haven't tested it, but I am optimistic since it has been nearly a decade since the original answer was provided.

Even if this is old, it's cool to know that you can always get values from system then set it by hand. This would work on every webdriver you use.

#!/usr/bin/env python
#! -*- coding: utf-8 -*-

import selenium
from selenium import webdriver

import os, sys, time

import wx

print "example with maximize_window()"
nav = webdriver.Firefox()
nav.maximize_window()
time.sleep(3)
nav.quit()

print 'example with fixed set_window_size("1024", "768")'
nav = webdriver.Firefox()
nav.set_window_size("1024", "768")
time.sleep(3)
nav.quit()

print "example grabbing size with wx (wxWidgets)"
nav = webdriver.Firefox()
app = wx.App(False) #wx.App(False) # the wx.App object must be created first.
screenxy = wx.GetDisplaySize()  # returns a tuple
nav.set_window_size(screenxy[0], screenxy[1])
time.sleep(3)
nav.quit()


sys.exit(0)

Answer 3

There is a really simple way to create a maximized window:

from selenium.webdriver.chrome.options import Options

chrome_options = Options()
# maximized window
chrome_options.add_argument("--start-maximized")

You can also use this library for maximizing the window and more, see the documentation: https://seleniumhq.github.io/selenium/docs/api/rb/Selenium/WebDriver/Chrome/Options.html

对于 Chrome，应该在包含修订的下一个版本中，实现： http : //code.google.com/p/chromedriver/issues/detail?id=65

Answer 5

I solve it with this line

self.driver = webdriver.Chrome()
self.driver.maximize_window()
