Question

我正在尝试编写一个Python脚本，使我能够访问网页并从该页面下载文件。我的第一次尝试只是到达那个页面，我尝试了以下代码：

import requests

url = 'https://www.google.com/?gws_rd=ssl' #using google as an example

r = requests.get(url)

print(r.url)

我收到了这个错误：

runfile('C:/Users/ME/Desktop/TMS502.py', wdir='C:/Users/ME/Desktop')
Traceback (most recent call last):

  File "<ipython-input-23-bc585dcceef8>", line 1, in <module>

有人可以帮帮我吗？

Answer 1

您收到该错误是因为远程端（在本例中为Google）正在关闭您的请求，否则您将无法再与其建立连接。

从错误：

ConnectionError: HTTPSConnectionPool(host='www.google.com', port=443): 
Max retries exceeded with url: /?gws_rd=ssl 
(Caused by <class 'socket.error'>: [Errno 10054] An existing connection was forcibly closed by the remote host)

我们可以查看source的提示：

class MaxRetryError(RequestError):
    """Raised when the maximum number of retries is exceeded.
    :param pool: The connection pool
    :type pool: :class:`~urllib3.connectionpool.HTTPConnectionPool`
    :param string url: The requested Url
    :param exceptions.Exception reason: The underlying error
    """

    def __init__(self, pool, url, reason=None):
        self.reason = reason

        message = "Max retries exceeded with url: %s (Caused by %r)" % (
            url, reason)

        RequestError.__init__(self, pool, url, message)

尝试另一个示例主机，您的代码应该可以使用，例如https://example.org。

错误消息＆＃34;远程主机＆＃34;强制关闭现有连接。来自您的操作系统（Windows），请求正在向您显示此文本以试图提供帮助。

无论如何，你是否还在烦恼：

from urllib2 import urlopen
u = urlopen("https://www.google.com/?gws_rd=ssl")
data = u.read()
u.close()

也许这会工作。
