python – 请求库：在cx_Freeze之后缺少SSL握手证书文件

我正在使用请求库在python 3.3中构建一个应用程序.
当我尝试获取具有SSL连接的URL时,我想使用verify = true验证它.
这在运行我的python脚本时非常有效.

当我冻结相同的脚本时,它会崩溃.它错过了一些东西,我真的无法弄清楚如何将它集成到我的冻结应用程序中.

我收到以下错误(这也会触发其他错误,但我不在这里发布)：

Traceback (most recent call last):

FileNotFoundError: [Errno 2] No such file or directory 

似乎缺少ca_certs.在请求库中有一个名为cacert.pem的文件,但我不知道这是否是丢失的文件以及如何导入它,因为它似乎没有集成到我的最终冻结包中.

解决方法:

查看请求源,似乎您可以将路径传递给cacert.pem文件作为verify = path,而不是verify = True.因此,您无需修改​​其工作请求.

您可以传递文件的路径以包含在cx_Freeze选项的include-files参数中(docs).你可以从请求中找到路径,所以这样的东西应该在你用来冻结它的setup.py中起作用：

import requests.certs
build_exe_options = {"include_files":[(requests.certs.where(),'cacert.pem')]}
