python - 除了一页上的一个 CSS 列表外，不抓取所有请求的数据

Question

我正在尝试抓取网页，但是尽管在 Chrome 中提供了正确的 CSS，但检查 Selenium 并没有抓取所有数据，它只抓取第一页的几率，如下所示，然后给出错误消息。

我重新测试了 CSS 并对其进行了多次更改，但是，Selenium Python 似乎无法正确抓取数据。

我也倾向于:

Traceback (most recent call last):
  File "C:/Users/Bain3/PycharmProjects/untitled4/Vpalmerbet1.py", line 1365, in <module>
    EC.element_to_be_clickable((By.CSS_SELECTOR, ('.match-pop-market a[href*="/sports/soccer/"]'))))
  File "C:\Users\Bain3\Anaconda3\lib\site-packages\selenium\webdriver\support\wait.py", line 80, in until
    raise TimeoutException(message, screen, stacktrace)
selenium.common.exceptions.TimeoutException: Message: 

我尝试过更改 CSS 以及使用 xpath 来:

#clickMe = wait(driver, 15).until(EC.element_to_be_clickable((By.CSS_SELECTOR, ('.match-pop-market a[href*="/sports/soccer/"]'))))

clickMe = wait(driver, 15).until(EC.element_to_be_clickable((By.XPATH, ("//*[@class='match-pop-market']//a[href*='/sports/soccer/']"))))

你可以看到 chrome inspects 检测到了这个 CSS

我的完整代码是:

from selenium import webdriver
driver = webdriver.Chrome()
driver.set_window_size(1024, 600)
driver.maximize_window()

try:
    os.remove('vtg121.csv')
except OSError:
    pass

driver.get('https://www.palmerbet.com/sports/soccer')

    #time.sleep(SCROLL_PAUSE_TIME)


    #new_height = driver.execute_script("return document.body.scrollHeight")
    #if new_height == last_height:

Answer 1

您的 XPath 不正确。请注意，像 [href*="/sports/soccer/"] 这样的谓词可以在 CSS 选择器中使用，而在 XPath 中你应该使用 [contains(@href, "/sports/soccer/")]。所以完整的行应该是

from selenium.common.exceptions import TimeoutException

try:
    clickMe = wait(driver, 15).until(EC.element_to_be_clickable((By.XPATH, "//*[@class='match-pop-market']//a[contains(@href, '/sports/soccer/')]")))
    clickMe1.click()
except TimeoutException:
    print("No link was found")
