python - 使用Python和Selenium访问网站时的花式访问时间(Trick elapsed visitation time when visiting a website using Python & selenium)

Question

Ok, so I am trying to create a program that allows the background of my Gnome desktop to tap into the stream of wallpapers used by Google's chromecast devices.

(好的，所以我正在尝试创建一个程序，该程序允许Gnome桌面的背景利用Google chromecast设备使用的壁纸流。)

Currently I use a loop function in Python that uses selenium and a Chrome webdriver to get the images that are dynamically displayed here:

(目前，我在Python中使用一个使用硒的循环函数和一个Chrome网络驱动程序来获取在此处动态显示的图像：)

https://clients3.google.com/cast/chromecast/home/

(https://clients3.google.com/cast/chromecast/home/)

My function works exactly like I want it to.

(我的功能完全像我想要的那样工作。)

However the problem is > whenever I visit this website in a browser it starts displaying random wallpapers in a random order, there seems to be a big selection of possible wallpapers, but whenever you reload the page it always shows only about 5 (max) different wallpapers.. since my script reloads the page in each loop, I only get about 5 different wallpapers out of it, while there should be a multitude of that available via the website.

(但是问题是 >每当我在浏览器中访问该网站时，它就会开始以随机顺序显示随机壁纸，似乎有很多可能的壁纸可供选择，但是每当您重新加载页面时，它总是仅显示大约5（最大）个不同墙纸..由于我的脚本在每个循环中都会重新加载页面，因此我只能从中获得大约5种不同的墙纸，而网站上应该有大量可用的墙纸。)

That leads me to question : Can I use selenium for Python to somehow trick the website into thinking I've been around longer then just a few seconds and thereby maybe showing me a different wallpaper?

(这就引出了一个问题 ：我可以使用Selenium for Python欺骗网站，让我认为自己待了更长的时间才几秒钟，从而可能给我展示了不同的墙纸吗？)

NB : I know I could also get the wallpapers from non-dynamic websites such as this one , I already got that one to work, but the goal now is to actually tap into the live Chromecast stream.

(NB ：我知道我也可以从非动态网站（例如该网站）获取壁纸，我已经可以使用它了，但是现在的目标是实际使用实时Chromecast流。)

I've searched if there might be an API somewhere for it, but couldn't find one so decided to go with my current approach.

(我搜索了某个地方是否有API，但是找不到一个决定使用我当前方法的API。)

My current code:

(我当前的代码：)

import io
import os
from PIL import Image
from pyvirtualdisplay import Display
from random import shuffle
import requests
import sched
from selenium import webdriver
import subprocess
import time

s = sched.scheduler(time.time, time.sleep)

def change_desktop():
    display = Display(visible=0, size=(800, 600))
    display.start()

    browser = webdriver.Chrome()
    urllist = ["https://clients3.google.com/cast/chromecast/home/v/c9541b08", "https://clients3.google.com/cast/chromecast/home"]
    shuffle(urllist)
    browser.get(urllist[0])
    element = browser.find_element_by_id("picture-background")
    image_source = element.get_attribute("src")
    browser.quit()
    display.stop()

    request = requests.get(image_source)
    image = Image.open(io.BytesIO(request.content))
    image_format = image.format
    current_dir = os.path.dirname(os.path.realpath(__file__))
    temp_local_image_location = current_dir + "/interactive_wallpaper." + image_format
    image.save(temp_local_image_location)
    subprocess.Popen(["/usr/bin/gsettings", "set", "org.gnome.desktop.background", "picture-uri", "'" + temp_local_image_location + "'"], stdout=subprocess.PIPE)
    s.enter(30, 1, change_desktop())

s.enter(30, 1, change_desktop())
s.run()
