Question

我现在使用APScheduler每10分钟自动执行一次脚本。它在打印后停止执行（“ [+]成功！机器人开始！”），它不会输出错误。我建议我对scheduler.add_job（trendingBot，'interval'，minutes = 10，args = [url，browser]）的声明不正确，我不确定如何解决。

# grabs all the trending quotes for that day
def getTrendingQuotes(browser):
    # wait until trending links appear, not really needed only for example
    all_trendingQuotes = WebDriverWait(browser, 10).until(
        lambda d: d.find_elements_by_css_selector('#trendingQuotes a')
    )
    return [link.get_attribute('href') for link in all_trendingQuotes]


def getStockDetails(url, browser):

    print(url)
    browser.get(url)

    quote_wrapper = browser.find_element_by_css_selector('div.quote-wrapper')
    quote_name = quote_wrapper.find_element_by_class_name(
        "quote-name").find_element_by_tag_name('h2').text
    quote_price = quote_wrapper.find_element_by_class_name("quote-price").text
    quote_volume = quote_wrapper.find_element_by_class_name(
        "quote-volume").text

    print("\n")
    print("Quote Name: " + quote_name)
    print("Quote Price: " + quote_price)
    print("Quote Volume: " + quote_volume)
    print("\n")

    convertToJson(quote_name, quote_price, quote_volume, url)


quotesArr = []

# Convert to a JSON  file


def convertToJson(quote_name, quote_price, quote_volume, url):
    quoteObject = {
        "url": url,
        "Name": quote_name,
        "Price": quote_price,
        "Volume": quote_volume
    }
    quotesArr.append(quoteObject)


def trendingBot(url, browser):
    browser.get(url)
    trending = getTrendingQuotes(browser)
    for trend in trending:
        getStockDetails(trend, browser)
    # requests finished, write json to file
    with open('trendingQuoteData.json', 'w') as outfile:
        json.dump(quotesArr, outfile)


def Main():
    scheduler = BlockingScheduler()
    chrome_options = Options()
    chrome_options.add_argument("--headless")
    # applicable to windows os only
    chrome_options.add_argument('--disable-gpu')

    url = 'https://www.tmxmoney.com/en/index.html'
    browser = webdriver.Chrome(
        r"C:\Users\austi\OneDrive\Desktop\chromeDriver\chromedriver_win32\chromedriver.exe", chrome_options=chrome_options)
    browser.get(url)

    os.system('cls')
    print("[+] Success! Bot Starting!")
    scheduler.add_job(trendingBot, 'interval', minutes=1, args=[url, browser])
    scheduler.start()
    #trendingBot(url, browser)
    browser.quit()


if __name__ == "__main__":
    Main()

默认情况下，APScheduler是非阻塞的，这意味着当您执行scheduler.add_job(..和scheduler.start()时，您的应用程序将继续运行到browser.quit()并最终运行到应用程序的末尾（在该位置退出）。

您似乎想要一个阻塞的调度程序，例如BlockingScheduler。

更改行：

scheduler = BackgroundScheduler()

到

scheduler = BlockingScheduler()

APScheduler和传递参数
