Request Delay - pheadrus - Nov-24-2021
Hi,
i m using requests and bs4 for https://www.binance.com/en/support/announcement/c-49?navId=49 this website. get request per 3 seconds for detecting latest news.
My codes ;
latest_news_url = ""
while True:
time.sleep(3)
source =
requests.get("https://www.binance.com/en/support/announcement/c-49?
avId=49")
soup = BeautifulSoup(source.text, 'html.parser')
...
...
lastest_news_url_detected = ...
if (lastest_news_url_detected == latest_news_url):
print("no news detected")
print(current_time)
else:
latest_news_url = lastest_news_url_detected
print (shared time)
print(current time)my current time is right,also website shared time is right. but my code working wrong..Its detecting after 7-8mins. For example latest news shared at 20.00- my console;Output:19.59.57 -no news detected
20.00.00 no news detected
20.00.03 no news detected
..
..
..
20.08.00 detect! shared time = 20.00.00RE: Request Delay - snippsat - Nov-25-2021
It's better to use schedule for this that run in a while true loop with time.sleep() added.
schedule would works fine this.
A example, so write to disk once then check against that file,if updated start again.
import schedule
import time, datetime
import requests
from bs4 import BeautifulSoup
def news(url):
response = requests.get(url)
soup = BeautifulSoup(response.content, 'lxml')
news = soup.select_one('#link-0-0-p1').get('href')
print('News run')
with open('news.txt', 'w') as f:
f.write(news)
return schedule.CancelJob
def check_update(url):
response = requests.get(url)
soup = BeautifulSoup(response.content, 'lxml')
news_update = soup.select_one('#link-0-0-p1').get('href')
with open('news.txt') as f:
if news_update == f.read():
print('No update on site')
print(datetime.datetime.utcnow())
else:
print('Site has gotten updated')
print(datetime.datetime.utcnow())
# Update start again once
news(url)
if __name__ == '__main__':
url = 'https://www.binance.com/en/support/announcement/c-49?avId=49'
schedule.every(10).seconds.do(news, url=url)
schedule.every(60).seconds.do(check_update, url=url)
while True:
schedule.run_pending()
time.sleep(1)
