我的情况比较特殊。我试了上面的答案，没有一个管用。我突然想，是不是和我的网络代理有关?你知道，我在中国大陆，如果没有代理，我无法访问像谷歌这样的网站。然后我关掉了网络代理，问题就解决了。

我有类似的问题，但下面的代码为我工作。

url = <some REST url>    
page = requests.get(url, verify=False)

verify=False禁用SSL验证。Try和catch可以像往常一样添加。

实现异常处理总是好的。它不仅有助于避免脚本意外退出，还有助于记录错误和信息通知。当使用Python请求时，我更喜欢捕获这样的异常:

    try:
        res = requests.get(adress,timeout=30)
    except requests.ConnectionError as e:
        print("OOPS!! Connection Error. Make sure you are connected to Internet. Technical Details given below.\n")
        print(str(e))            
        renewIPadress()
        continue
    except requests.Timeout as e:
        print("OOPS!! Timeout Error")
        print(str(e))
        renewIPadress()
        continue
    except requests.RequestException as e:
        print("OOPS!! General Error")
        print(str(e))
        renewIPadress()
        continue
    except KeyboardInterrupt:
        print("Someone closed the program")

这里的renewIPadress()是一个用户定义函数，它可以在IP地址被阻塞时更改IP地址。你可以不用这个函数。

即使在安装pyopenssl和尝试各种python版本后，我也无法在Windows上工作(而它在mac上工作得很好)，所以我切换到urllib，它可以在python 3.6(从python .org)和3.7 (anaconda)上工作

import urllib 
from urllib.request import urlopen
html = urlopen("http://pythonscraping.com/pages/page1.html")
contents = html.read()
print(contents)

当您向https://itunes.apple.com的公共IP地址发送过多请求时，就会发生这种情况。正如你所看到的，这是由于某些原因导致的，不允许/阻止访问与https://itunes.apple.com的公共IP地址映射。一个更好的解决方案是下面的python脚本，它计算任何域的公共IP地址，并创建到/etc/hosts文件的映射。

import re
import socket
import subprocess
from typing import Tuple

ENDPOINT = 'https://anydomainname.example.com/'
ENDPOINT = 'https://itunes.apple.com/'

def get_public_ip() -> Tuple[str, str, str]:
    """
    Command to get public_ip address of host machine and endpoint domain

    # bash_command = """host myip.opendns.com resolver1.opendns.com | \

    # bash_command = """curl ifconfig.co"""
    # bash_command = """curl ifconfig.me"""
    bash_command = """ curl icanhazip.com"""
    my_public_ip = subprocess.getoutput(bash_command)
    my_public_ip = re.compile("[0-9.]{4,}").findall(my_public_ip)[0]
    end_point_domain = (
        ENDPOINT.replace("https://", "")
        .replace("http://", "")
        .replace("/", "")
    )
    end_point_ip_address = socket.gethostbyname(end_point_domain)
    return my_public_ip, end_point_ip_address, end_point_domain

    bash_command = """echo "{}    {}" >> /etc/hosts""".format(ip_address, domain)
    output = subprocess.getoutput(bash_command)
    return output


if __name__ == "__main__":
    my_public_ip, end_point_ip_address, end_point_domain = get_public_ip()
    output = set_etc_host(ip_address=end_point_ip_address, domain=end_point_domain)
    print("My public IP address:", my_public_ip)
    print("ENDPOINT public IP address:", end_point_ip_address)
    print("ENDPOINT Domain Name:", end_point_domain )
    print("Command output:", output)

你可以在运行你想要的函数之前调用上面的脚本:)

只需要导入时间 并补充:

time.sleep(6)

在for循环的某个地方，以避免在短时间内向服务器发送太多请求。 数字6意味着:6秒。 从1开始测试数字，直到达到有助于避免问题的最小秒数。
