python - Python bot 在本地运行良好，但在 Heroku 崩溃
问题描述
我想为我的机器人使用 heroku 来检查亚马逊的价格。问题是当我运行 heroku logs --tail 时出现此错误。

我已按照步骤在 gmail 上访问不太安全的应用程序。我添加了 Procfile：worker:python scraper.py。我不知道该怎么办了。

def check_price():
page = requests.get(URL, headers=headers)
soup = BeautifulSoup(page.content, 'html.parser')
title = soup.find(id="productTitle").get_text()
price = soup.find(id="priceblock_ourprice").get_text()
converted_price = price
s = converted_price
list_number = re.findall(r'\d+', s)
num = "".join(list_number)

if (first_num < 6000):
send_mail()
print(title)
print(float(first_num))
所以在这里我使用的是一个 gmail 帐户，我的应用程序不太安全，我将其发送到我的主要 gmail 帐户。当我在本地运行它时，它可以完美运行。
def send_mail():
server = smtplib.SMTP('smtp.gmail.com', 587)
server.ehlo()
server.starttls()
server.ehlo
server.login('gmail', 'password')
subject = 'Price fell down'
body = 'check the amazon link. https://www.amazon.se/Sony-ILCE6000LB-CEC-Alpha-Systemkamera-24-3mp/dp/B00IE9XHE0/ref=sr_1_1?dchild=1&keywords=systemkamera&qid=1629705873&s=videogames&sr=1-1'
msg = f"Subject: {subject}\n\n{body}"
server.sendmail(
'gmail',
'gmail',
msg
)
print("email is sent")
server.quit()
while (True):
check_price()
time.sleep(60 * 60)
