[英]In Python, how do I give each member of an Enum its own implementation of an Enum instance method?
[英]How to give each URL its own threading
我一直在研究一个小型 PoC,我一直在努力提高我对线程的了解,但不幸的是我被卡住了,我在这里,
import time
found_products = []
site_catalog = [
"https://www.graffitishop.net/Sneakers",
"https://www.graffitishop.net/T-shirts",
"https://www.graffitishop.net/Sweatshirts",
"https://www.graffitishop.net/Shirts"
]
def threading_feeds():
# Create own thread for each URL as we want to run concurrent
for get_links in site_catalog:
monitor_feed(link=get_links)
def monitor_feed(link: str) -> None:
old_payload = product_data(...)
while True:
new_payload = product_data(...)
if old_payload != new_payload:
for links in new_payload:
if links not in found_products:
logger.info(f'Detected new link -> {found_link} | From -> {link}')
# Execute new thread as we don't want to block this function wait for filtering() to be done before continue
filtering(link=found_link)
else:
logger.info("Nothing new")
time.sleep(60)
continue
def filtering(found_link):
...
1 - 我目前正在尝试做一个我有多个链接开始的监视器,我的计划是我希望每个 url 同时运行,而不是需要一个一个地等待:
def threading_feeds():
# Create own thread for each URL as we want to run concurrent
for get_links in site_catalog:
monitor_feed(link=get_links)
我怎样才能做到这一点?
2 - 如果我们似乎在monitor_feed
内找到了给定 URL 出现的新产品,我该如何设置一个新线程来执行调用filtering(link=found_link)
? 我不想在它继续循环返回While True
之前等待它完成,而是它应该在后台执行filtering(link=found_link)
,同时它仍然执行monitor_feed
import concurrent.futures
with concurrent.futures.ThreadPoolExecutor() as executor:
executor.map(monitor_feed, site_catalog)
您可以使用ThreadPoolExecutor 。
