在Symfony中手动创建表单(Creating a form manually in Symfony)

 它看起来像只有一个http请求被发送。 在这一行上： 
 
timelink = requests.get('http://example.com/somelink')
 
 abcStart（）函数正在接收http响应，并在其运行的整个时间内使用该值。 这会导致我们每次都刮同一页。 如果我们想要有一个不同的页面来抓取每个循环迭代，我们需要每次执行另一个http请求。 像这样的东西： 
 
def abcStart(timeLink):

while True:
    res = requests.get(timeLink) # send request here
    res.raise_for_status()
    timestamp = BeautifulSoup(res.content, 'html.parser').find_all('b')

    if timestamp[0].text == otherTimestamp[0].text:
        work on something
        break
    if timestamp[0].text > otherTimestamp[0].text:
         continue
    else:
        print('not yet')
    time.sleep(30)
break

timeLink = 'http://example.com/somelink' # declare url

threadobj = threading.Thread(target=abcStart, args=(timelink))
threadobj.start()
threadobj.join()

It looks like there is only one http request being sent. On this line:
 
timelink = requests.get('http://example.com/somelink')
 
the abcStart() function is receiving the http response, and using that one value the whole time it is running. This will cause us to scrape the same page every time. If we want to have a different page to scrape for each loop iteration, we need to perform another http request each time. Something like this:
 
def abcStart(timeLink):

while True:
    res = requests.get(timeLink) # send request here
    res.raise_for_status()
    timestamp = BeautifulSoup(res.content, 'html.parser').find_all('b')

    if timestamp[0].text == otherTimestamp[0].text:
        work on something
        break
    if timestamp[0].text > otherTimestamp[0].text:
         continue
    else:
        print('not yet')
    time.sleep(30)
break

timeLink = 'http://example.com/somelink' # declare url

threadobj = threading.Thread(target=abcStart, args=(timelink))
threadobj.start()
threadobj.join()
