Discord.py 无法获得证书

问题描述

我是否必须在我的系统中安装/生成/下载新证书，或者我是否有可能以某种方式禁用 python 中的证书?(ubuntu 18，python 3.7，discord.py 最新)

Do I have to install/generate/download new certificate inside my system or is it possible for me somehow to disable certificates inside the python? (ubuntu 18, python 3.7, discord.py latest)

这是通过游戏客户端内部的 python 完成的.如果我从系统的 python (3.6) 中做同样的事情 - 没有错误，连接很好.他们说"这可能是因为游戏客户端没有看到根证书"或类似的东西.

This is done from the python that is inside the game client. If I do the same from the system's python (3.6) - no errors, connection is fine. "They say" it could be because the game client does not see "root certificates" or something like that.

更新:了解如何检查证书.

Update: Found out how to check certificates.

(with ssl error)
Initializing Discord...
DefaultVerifyPaths(cafile=None, capath=None, openssl_cafile_env='SSL_CERT_FILE', openssl_cafile='/usr/local/ssl/cert.pem', openssl_capath_env='SSL_CERT_DIR', openssl_capath='/usr/local/ssl/certs')


(this works fine)
igor@Linbox:~/Downloads$ python3.6 -c "import ssl; print(ssl.get_default_verify_paths())"
DefaultVerifyPaths(cafile=None, capath='/usr/lib/ssl/certs', openssl_cafile_env='SSL_CERT_FILE', openssl_cafile='/usr/lib/ssl/cert.pem', openssl_capath_env='SSL_CERT_DIR', openssl_capath='/usr/lib/ssl/certs')

猜猜我的问题是 capath 是空的.

Guess that is my problem that capath is empty.

推荐答案

没想到解决方案看起来很简单:

Unexpectedly the solution appeared quite simple:

ssl.get_default_verify_paths() 用于带有 ssl 错误的 python 指向:openssl_capath='/usr/local/ssl/certs' 而本机"系统中的 python 显示 openssl_capath='/usr/lib/ssl/certs'.

ssl.get_default_verify_paths() for the python with the ssl error was pointing to: openssl_capath='/usr/local/ssl/certs' while the "native" python from the system showed openssl_capath='/usr/lib/ssl/certs'.

DefaultVerifyPaths(
  cafile=None,
  capath=None,
  openssl_cafile_env='SSL_CERT_FILE',
  openssl_cafile='/usr/local/ssl/cert.pem',
  openssl_capath_env='SSL_CERT_DIR',
  openssl_capath='/usr/local/ssl/certs'
)

我已经检查了两个位置:'/usr/local/' - 为空(没有 ssl/certs 文件夹)'/usr/lib/ssl/certs' 有一个指向 '/etc/ssl/certs' 的符号链接所以我做了同样的符号链接:在 '/usr/local/' 里面添加了 '/ssl/' + ln -s '/etc/ssl/certs' 证书

I've checked both locations: '/usr/local/' - was empty (it had no ssl/certs folders) '/usr/lib/ssl/certs' had a symlink to '/etc/ssl/certs' So I made the same symlink: inside '/usr/local/' added '/ssl/' + ln -s '/etc/ssl/certs' certs

然后我再次检查了 ssl.get_default_verify_paths()

DefaultVerifyPaths(
  cafile=None,
  capath='/usr/local/ssl/certs',  <-- not empty now
  openssl_cafile_env='SSL_CERT_FILE',
  openssl_cafile='/usr/local/ssl/cert.pem',
  openssl_capath_env='SSL_CERT_DIR',
  openssl_capath='/usr/local/ssl/certs'
)

问题消失了.它现在正在工作.

The problem disappeared. It is working now.
