请求库：cx_Freeze之后缺少SSL握手证书文件 [英] Requests library: missing SSL handshake certificates file after cx_Freeze

问题描述

我正在python 3.3中构建一个使用请求库的应用程序。
当我尝试通过SSL连接获取URL时，我想使用verify = true进行验证。
这在运行我的python脚本时非常有效。

I'm building an application in python 3.3 which uses the requests library. When I try to get a URL with SSL connection I want to verify it with verify = true. This works perfectly when running my python scripts.

当我冻结相同的脚本时，它会崩溃。它错过了一些东西，我真的不知道如何将其集成到冻结的应用程序中。

When I freeze the same scripts it crashes. It misses something and I really cant figure out how to integrate it in my frozen application.

我收到以下错误（也会触发其他错误，但我不在此发布）：

I get the following error (which also triggers other errors, but I don't post them here):

Traceback (most recent call last):

似乎缺少ca_certs。在请求库中有一个名为cacert.pem的文件，但是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最终冻结的程序包中。

It seems that ca_certs is missing. There is a file called cacert.pem in the requests library, but I don't know if this is the missing file and how to import it since it seems to be not integrated into my final frozen package.

推荐答案

看请求源，看来您可以将路径传递到 cacert.pem 文件为 verify = path ，而不是 verify = True 。因此，您无需修改​​请求即可工作。

Looking at the requests source, it seems you can pass the path to the cacert.pem file as verify=path, instead of verify=True. So you don't need to modify requests for it to work.

您可以传递文件的路径以包含在 include-files中 cx_Freeze选项的参数（ docs ）。您可以从请求中找到路径，因此在冻结它的 setup.py 中应该可以进行以下操作：

You can pass the path of a file to include in the include-files parameter of the cx_Freeze options (docs). You can find the path from requests, so something like this should work in the setup.py you use to freeze it:

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