如何在Selenium Chrome Python中设置窗口大小 [英] How to set window size in Selenium Chrome Python
问题描述
以下用于调整硒铬窗口大小的代码不起作用:
The following code to resize a selenium chrome window does not work:
driver.set_window_size(1920, 1080)
time.sleep(5)
size = driver.get_window_size()
print("Window size: width = {}px, height = {}px.".format(size["width"], size["height"]))
输出的来源是:
Window size: width = 1044px, height = 788px
我也尝试过使用选项来设置驱动程序创建时的窗口大小(还有很多其他事情，在下面似乎是注释)，但也无法使其起作用:
I've also tried using options to set the window size on driver creation (and lots of other things, seem comments below), but can't get it to work either:
options.add_argument("--window-size=1920,1080")
我正在使用Selenium 3.14.0，chrome驱动程序版本72.0.3626.109并在后台/无头模式下运行:我确实需要在后台运行我的代码，这意味着它会在后台自动启动.我认为无头和背景之间有微妙的区别，无头与启动时是与特定用户相关联的，背景也无头，但可能与特定用户无关，并且可能具有其他特质-我开始认为这可能成为我的问题的一部分.
I am using selenium 3.14.0, chrome driver version 72.0.3626.109 and running in background / headless mode: I am literally needing to run my code in background, meaning it launches automatically in the background. I think there is a subtle difference between headless, which when launched is associated with a particular user, and background, which is also headless but may not be associated with a particular user and may have other idiosyncrasies - I'm starting to think this may be part of my issue.
我想让chrome驱动程序正常工作，因为firefox不在后台运行(我需要)，也就是说很痛苦.
I'd like to get chrome driver to work because firefox does not run in the background (which I need), and ie is a pain.
我想弄清楚这一点，因为当窗口很小时，我看不到需要单击的元素.
I want to figure this out because I can't see an element I need to click when the window is so small.
推荐答案
有点不清楚为什么以及被困在何处.可能与height = {}px.中一样的 . 造成了混乱.也许与-headless参数一起，我可以如下设置/获取 Chrome 浏览器 Window Size :
A bit unclear why and exactly where you are stuck. Possibly the extra . as in height = {}px. is creating the chaos. Perhaps along with -headless argument I am able to set/retrieve the Chrome browser Window Size as follows:

代码块:
Code Block:
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
options = Options()
options.add_argument("--headless")
options.add_argument("window-size=1400,600")
driver = webdriver.Chrome(chrome_options=options, executable_path=r'C:\Utility\BrowserDrivers\chromedriver.exe', service_args=["--log-path=./Logs/DubiousDan.log"])
driver.get("http://google.com/")
print ("Headless Chrome Initialized")
print(driver.get_window_size())
driver.set_window_size(1920, 1080)
size = driver.get_window_size()
print("Window size: width = {}px, height = {}px".format(size["width"], size["height"]))
driver.quit()
控制台输出:
Console Output:
Headless Chrome Initialized
{'width': 1400, 'height': 600}
Window size: width = 1920px, height = 1080px
