在 Python 中使用 Selenium 检查 URL 更改的最佳方法是什么? [英] What is the best way to check URL change with Selenium in Python?

问题描述

所以，我想做的是在特定网页上运行一个函数(与我的正则表达式匹配).

So, what's I want to do is to run a function on a specific webpage (which is a match with my regex).

现在我每秒钟都在检查它并且它有效，但我确信有更好的方法(因为它正在通过获取请求淹没该网站).

Right now I'm checking it every second and it works, but I'm sure that there is a better way (as it's flooding that website with getting requests).

while flag:
    time.sleep(1)
    print(driver.current_url)
    if driver.current_url == "mydesiredURL_by_Regex":
        time.sleep(1)
        myfunction()

我想用 WebDriverWait 以某种方式做到这一点，但不确定如何做.

I was thinking to do that somehow with WebDriverWait but not really sure how.

推荐答案

没错.首先，看看内置预期条件是否可以解决这个问题:

Exactly. First of all, see if the built-in Expected Conditions may solve that:

• title_is
• title_contains

示例用法:

from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC

wait = WebDriverWait(driver, 10)
wait.until(EC.title_is("title"))
wait.until(EC.title_contains("part of title"))

如果没有，您始终可以创建一个自定义预期条件以等待 url 匹配所需的正则表达式.

If not, you can always create a custom Expected Condition to wait for url to match a desired regular expression.
