Unable to get local issuer certificate when using requests in python
提问by innocentDrifter
here is my code
这是我的代码
import requests;
url='that website';
headers={
'Accept':'text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8',
'Accept-Language':'zh-CN,zh;q=0.9,en;q=0.8,ja;q=0.7',
'User-Agent':'Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/68.0.3440.106 Safari/537.36'
};
r = requests.get(url,headers=headers);
print(r);
print(r.status_code);
then it ran into this:
然后它遇到了这个：
requests.exceptions.SSLError: HTTPSConnectionPool(host='www.xxxxxx.com', port=44 3): Max retries exceeded with url: xxxxxxxx (Caused by SSLEr ror(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1045)')))
requests.exceptions.SSLError: HTTPSConnectionPool(host='www.xxxxxx.com', port=44 3): Max retries exceeded with url: xxxxxxxx (Caused by SSLEr ror(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed) : 无法获得本地颁发者证书 (_ssl.c:1045)')))
what should i do?
我该怎么办？

It's not recommendedto use verify = Falsein your organization's environments. This is essentially disabling SSL verification.
它不建议使用verify = False您的组织环境。这实质上是禁用 SSL 验证。
Sometimes, when you are behind a company proxy, it replaces the certificate chain with the ones of Proxy. Adding the certificates in cacert.pem used by certifi should solve the issue. I had similar issue. Here is what I did, to resolve the issue -
有时，当您使用公司代理时，它会用代理的证书链替换证书链。在 certifi 使用的 cacert.pem 中添加证书应该可以解决问题。我有类似的问题。这是我所做的，以解决问题-
- Find the path where cacert.pem is located -
- 找到cacert.pem所在的路径——
Install certifi, if you don't have. Command:
pip install certifi
如果没有，请安装证书。命令：
pip install certifi
import certifi
certifi.where()
C:\Users\[UserID]\AppData\Local\Programs\Python\Python37-32\lib\site-packages\certifi\cacert.pem
Open the URL on a browser. Download the chain of certificates from the URL and save as Base64 encoded .cer files.
Now open the cacert.pem in a notepad and just add every downloaded certificate contents (
---Begin Certificate--- *** ---End Certificate---) at the end.
在浏览器上打开 URL。从 URL 下载证书链并另存为 Base64 编码的 .cer 文件。
现在在记事本中打开 cacert.pem 并在最后添加每个下载的证书内容 (
---Begin Certificate--- *** ---End Certificate---)。

In my case it was a running Fiddler...
就我而言，它是一个正在运行的 Fiddler ......
