Caused by SSLError

 1 import requests
 2 from bs4 import BeautifulSoup

 5 def get_page():
 6     url = ‘https://movie.douban.com/cinema/nowplaying/changsha/‘
 7     headers = {
 8         "User-Agent": "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (Khtml, like Gecko) Chrome/63.0.3239.132 Safari/537.36"
 9     }
10     response = requests.get(url, headers=headers)
11     text = response.text
12     return text
13 
29 
30 if __name__ == ‘__main__‘:
31     text = get_page()
32

程序运行报错：requests.exceptions.SSLError: HTTPSConnectionPool(host=‘movie.douban.com‘, port=443): Max retries exceeded with url: /cinema/nowplaying/changsha/ (Caused by SSLError(SSLError(1, ‘[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:749)‘),))

其实很奇怪，我昨天晚上的时候代码还正常运行了，今天竟然就报错了，百度找到一个解决方法，原文内容：

问题描述：

测试HTTPS SSL 协议的网站接口，用Python Locust模块，不论POST还是GET都提示错误：

SSLError
Max retries exceeded with url: /action.php?m=upload 
(Caused by SSLError(SSLError(1, u‘[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:581)‘),))",),)

 

后面查官网locust.io,终于找到解决方法：https://docs.locust.io/en/latest/api.html

 

request(method, url, name=None, catch_response=False, **kwargs)

Constructs and sends a requests.Request. Returns requests.Response object.

Parameters:

method – method for the new Request object. url – URL for the new Request object. name – (optional) An argument that can be specified to use as label in Locust’s statistics instead of the URL path. This can be used to group different URL’s that are requested into a single entry in Locust’s statistics. catch_response – (optional) Boolean argument that, if set, can be used to make a request return a context manager to work as argument to a with statement. This will allow the request to be marked as a fail based on the content of the response, even if the response code is ok (2xx). The opposite also works, one can use catch_response to catch a request and then mark it as successful even if the response code was not (i.e 500 or 404). params – (optional) Dictionary or bytes to be sent in the query string for the Request. data – (optional) Dictionary or bytes to send in the body of the Request. headers – (optional) Dictionary of HTTP Headers to send with the Request. cookies – (optional) Dict or CookieJar object to send with the Request. files – (optional) Dictionary of ‘filename‘: file-like-objects for multipart encoding upload. auth – (optional) Auth tuple or callable to enable Basic/Digest/Custom HTTP Auth. timeout (float or tuple) – (optional) How long to wait for the server to send data before giving up, as a float, or a (connect timeout, read timeout) tuple. allow_redirects (bool) – (optional) Set to True by default. proxies – (optional) Dictionary mapping protocol to the URL of the proxy. stream – (optional) whether to immediately download the response content. Defaults to False. verify – (optional) if True, the SSL cert will be verified. A CA_BUNDLE path can also be provided. cert – (optional) if String, path to ssl client cert file (.pem). If Tuple, (‘cert’, ‘key’) pair.

利用verify参数，直接在POST/GET请求添加verify = False参数，搞定，

 

这是HTTPS网站所做的SSL证书认证，默认是True的，设置为False之后对测试没有影响；

当然如果知道证书的路径，应该也可以用cert设置.pem文件的路径，也可以解决

在代码第10行更改代码为

response = requests.get(url, headers=headers， verify=False)，程序可以正常运行。
另外找到其他的解决方法，可是才刚开始学，不知道怎么使用。
