python 中的 http post 请求非常慢

Question

我创建了一个 python 脚本，它从 facebook 图 api 收集 json 数据并检查用户 job_title 信息。

通过使用此脚本，我通知用户通过聊天机器人更新他们的 job_title，但此过程需要太多时间才能向所有用户发送请求。

import json
import requests

users_url = Facebook API to fetch user details
MESSAGE_TO_SEND = '....PLEASE UPDATE JOB TITLE....'

ACCESS_TOKEN = Page_Access_token

def reply(user_id, msg,ACCESS_TOKEN):
    data = {
        "recipient": { "id": user_id },
        "message": { "text": msg }
    }

    resp = requests.post("https://graph.facebook.com/v9.0/me/messages?access_token="+ ACCESS_TOKEN, json=data)
    print('Message Sent to : ',user_id)
    # print(resp.content, resp, 'response from facebook')

def header(ACCESS_TOKEN):
    return {'Authorization': 'Bearer ' + ACCESS_TOKEN}

def user_data(ACCESS_TOKEN):
    
    headers = header(ACCESS_TOKEN)
    data = requests.get(users_url,headers=headers)
    result_json = json.loads(data.text)
    resources = result_json['Resources']
    
    for titles in range(0,len(resources)):
            if 'title' not in resources[titles]:
                user_id = str(resources[titles]['id'])
                reply(user_id, MESSAGE_TO_SEND,ACCESS_TOKEN)


user_data(ACCESS_TOKEN)

请帮助我....我能做什么？

调整示例here...

from concurrent.futures import ThreadPoolExecutor
from concurrent.futures import as_completed
import time

def square(n):
    time.sleep(3.0)
    print( n * n )

def main():
    values = range(10)
    with ThreadPoolExecutor(max_workers = 5) as executor:
        results = executor.map(square, values)
    # for result in results:
        # print(result)

if __name__ == '__main__':
    st = time.time()
    main()
    et = time.time()
    print('{:.3f} seconds'.format(et-st))

将 values 替换为您的 user_ids 列表，将 square 替换为您的 reply 函数并将 max_workers 设置为您喜欢的数字。
