我尝试使用Python同时发送许多请求，但出现以下错误：2019-05-04 08:32:04,871 - telegram.vendor.ptb_urllib3.urllib3.connectionpool - WARNING - Connection pool is full, discarding connection: <>

我写了以下代码：

主回路：

^{pr2}$

使用retrieve_page_v2并因此发出请求的方法之一：def analyse_fixture(fixture, live=False, upcoming=False, odds=False, countries={}):

base_url = "https://www.flashscore.com/match/" + fixture + "/"

summary_url = "https://d.flashscore.com/x/feed/d_su_" + fixture + "_en_1"

statistics_url = "https://d.flashscore.com/x/feed/d_st_" + fixture + "_en_1"

h2h_url = "https://d.flashscore.com/x/feed/d_hh_" + fixture + "_en_1"

base_soup = retrieve_page_v2(base_url)

h2h_soup = retrieve_page_v2(h2h_url, True)

summary_soup = retrieve_page_v2(summary_url, True)

home_overal = head2heads[0]

away_overal = head2heads[1]

h2h = head2heads[2]

home_matches = home_overal.find('table').find('tbody').find_all('tr')

away_matches = away_overal.find('table').find('tbody').find_all('tr')

if(len(home_matches) > 10 and len(away_matches) > 10):

home_overal_details_process = Thread(target=analyse_details, args=(home_matches, home, away, statistics_in_league, "home_matches"))

away_overal_details_process = Thread(target=analyse_details, args=(away_matches, away, home, statistics_in_league, "away_matches"))

home_overal_details_process.start()

away_overal_details_process.start()

else:

exit()

home_home_matches = h2h_soup.find('div', {'id': 'tab-h2h-home'}).find('table').find('tbody').find_all('tr')

away_away_matches = h2h_soup.find('div', {'id': 'tab-h2h-away'}).find('table').find('tbody').find_all('tr')

if(len(home_home_matches) > 10 and len(away_away_matches) > 10):

home_home_details_process = Thread(target=analyse_details, args=(home_home_matches, home, away, statistics_in_league, "home_home_matches"))

away_away_details_process = Thread(target=analyse_details, args=(away_away_matches, away, home, statistics_in_league, "away_away_matches"))

home_home_details_process.start()

away_away_details_process.start()

else:

exit()

away_away_details_process.join()

home_home_details_process.join()

away_overal_details_process.join()

home_overal_details_process.join()

从analyze_fixture内部调用的方法，它也使用retrieve_page_v2def analyse_details(matches, team, team_2, statistics, name=""):

for match in matches[0:10]:

match_code = match.get('onclick')[17:25]

if(db.child("matches").child(match_code).child('total_goals').get().val() == None or db.child("matches").child(match_code).child("total_corners").get().val() == None or db.child("matches").child(match_code).child('winner').get().val() == None or db.child("matches").child(match_code).child('fh_winner').get().val() == None):

home_corners = "Unknown"

away_corners = "Unknown"

total_corners = "Unknown"

base_url = "https://www.flashscore.com/match/" + match_code

summary_url = "https://d.flashscore.com/x/feed/d_su_" + match_code + "_en_1"

statistics_url = "https://d.flashscore.com/x/feed/d_st_" + match_code + "_en_1"

base_soup = retrieve_page_v2(base_url)

summary_soup = retrieve_page_v2(summary_url, True)

teams = base_soup.find_all('a', {'class': 'participant-imglink'})

if(statistics):

statistics_soup = retrieve_page_v2(statistics_url, True)

发出请求的retrieve page方法def retrieve_page_v2(url, use_headers=False):

headers = {

"User-Agent": "core",

"Accept": "*/*"

"Accept-Language:" "*",

"X-Requested-With": "XMLHttpRequest",

"Connection": "keep-alive"

}

if(use_headers):

response = requests.get(url, headers=headers)

else:

response = requests.get(url)

return BeautifulSoup(response.content, features="lxml")

有人能帮我解决这个问题吗？我尝试过使用aiohttp，但似乎无法将其融入我编写的代码中
