请求库:cx_Freeze 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
我正在使用请求库的 python 3.3 构建应用程序.当我尝试通过 SSL 连接获取 URL 时,我想使用 verify = true 来验证它.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.它遗漏了一些东西,我真的不知道如何将它集成到我冻结的应用程序中.
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(这也会触发其他错误,但我不会在此处发布它们):
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.requests 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.
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
查看请求源,似乎可以将 cacert.pem
文件的路径传递为 verify=path
,而不是 verify=True
.因此,您无需修改请求即可使其工作.
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.
您可以传递要包含在 cx_Freeze 选项的 include-files
参数中的文件路径 (docs).您可以从请求中找到路径,因此这样的内容应该可以在用于冻结它的 setup.py
中工作:
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')]}
