Python/Selenium使脚本在输入失败时返回循环，然后重试

Question

我编码了一个"bot"；这触动了一个按钮——但事情并没有那么简单。

一旦机器人点击按钮，第二个按钮就会出现，机器人就会点击它，但随后计时器就会启动；第一个"；按钮仍然存在，但不是第二个按钮(当计时器停止时，这个按钮将再次出现(。我希望代码继续执行单击两个按钮的过程，即使有计时器，并且程序找不到第二个按钮的路径。(代码循环返回，寻找第二个按钮，但没有找到，因此打印出一个错误：(

Process finished with exit code 1

因此，我用try:和except:编写了一个exeption，这样它就会返回主页，如果出现错误，就会导航回按钮，但代码会停止——但我希望它保持循环，继续尝试单击按钮。

如果你更高级，有没有办法读取计时器，并在计时器达到某个值后重试？计时器HTML:

<div id="c2VuZC9mb2xsb3dlcnNfdGlrdG9s">
<script type="text/javascript">
clearInterval(cltimer);
var et88e8a9cbc190762b = 420
function updatetimer() {
var ogqsbud75e2aaab9a29662 = Math.round((et88e8a9cbc190762b - 30)/60);
var lzrdp0381a = et88e8a9cbc190762b % 60;
if (lzrdp0381a < 10) {
lzrdp0381a = '0' + lzrdp0381a; 
}
$('#aqzcfpledc4ad').html('Please wait ' + ogqsbud75e2aaab9a29662 + ' minute(s) ' + lzrdp0381a + ' seconds for your next submit!');
if (et88e8a9cbc190762b <= 0) {
clearInterval(cltimer);
$('#aqzcfpledc4ad').html('Next Submit: READY....!');
} else {
et88e8a9cbc190762b--; 
}
}
var cltimer = setInterval('updatetimer()', 1000);
</script>
<h4 style="text-align:center;color:#337ab7;font-weight:bold;font-size:115%;" id="aqzcfpledc4ad">Please wait 6 minute(s) 53 seconds for your next submit!</h4></div>

这是我的代码：

paste = driver.find_element(By.XPATH, "/html/body/div[4]/div[6]/div/form/div/input")
paste.send_keys(link,Keys.RETURN)

#make code go back to loop

这是我找到的解决方案：阅读#了解更多解释

# import web interface modules:
from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import Select
# sleep module to make script wait while website loads
from time import sleep

# Link chromedriver to the script (chromedriver enables the interface)
PATH = "C:Program Files (x86)chromedriver.exe"
driver = webdriver.Chrome(PATH)
# get the website by the url
driver.get("https://zefoy.com/")
# take an input
vidUrl = input("url: ")
# I figured out that we can use a function as a loop
def loop1():
global i
sleep(10)
# I also used a try/except loop so the code doesn't exit and prints an error but continues on
try:
# There is a captcha at the beginning that the user has to solve
driver.find_element(By.XPATH, "/html/body/div[4]/div[1]/div[3]/div/div[5]/div/button").click()
except:
print("Solve Captcha!, Refreshing...")
driver.refresh() #refreshing if captcha doesn't get solved to avoid being stuck
loop1()
# Interacting with the web interface using another try/except loop
try: 
sleep(2)
driver.find_element(By.XPATH, "/html/body/div[4]/div[6]/div/form/div/input").send_keys(vidUrl)
sleep(1)
driver.find_element(By.XPATH, "/html/body/div[4]/div[6]/div/form/div/div/button").click()
sleep(1)
driver.find_element(By.XPATH, "/html/body/div[4]/div[6]/div/div/div[1]/div/form/button").click()
sleep(2)
driver.refresh()
i += 1
total = i * 500
print("Success delivered!")
sleep(5)
loop1()
except: 
# if the upper part fails then the script is going to execute this section
print("Timer still running, trying again in a minute")
# driver.refresh resets the web interface:
driver.refresh() 
sleep(5)
# we make the script refresh and wait for the page to load 
# loops brings the code back to the loop
loop1() 
# input to start the bot 
bot = int(input("Type 1 to startn"))

if bot == 1:
print('starting engine...')
loop1()
else:
print('error')
