如何对请求使用多线程处理？

Question

你好，我有一段使用Python的代码，它使用了requests模块：

import requests

url1 = "myurl1" # I do not remember exactly the exact url
reponse1 = requests.get(url1)
temperature1 = reponse1.json()["temperature"]

url2 = "myurl2" # I do not remember exactly the exact url
reponse2 = requests.get(url2)
temperature2 = reponse2.json()["temp"]

url3 = "myurl3" # I do not remember exactly the exact url
reponse3 = requests.get(url3)
temperature3 = reponse3.json()[0]

print(temperature1)
print(temperature2)
print(temperature3)

实际上我得告诉你这有点慢。。。你有办法提高我的代码速度吗？我想使用多线程，但我不知道如何使用它。。。你知道吗

非常感谢！你知道吗

试试Python executors：

import requests
from concurrent.futures import ThreadPoolExecutor, as_completed
from multiprocessing import cpu_count

urls = ['/url1', '/url2', '/url3']
with ThreadPoolExecutor(max_workers=2*cpu_count()) as executor:
    future_to_url = {executor.submit(requests.get, url): url for url in urls}
    for future in as_completed(future_to_url):
        response = future.result()  # TODO: handle exceptions here
        url = future_to_url[future]
        # TODO: do something with that data
