python - Django：SSL 证书问题（“SSL 连接错误：收到的消息意外或格式错误”）

问题描述

我正在使用 Windows 10、Python 3.7.6。使用以下软件包：

# Name                    Version                   Build  Channel
mysql-connector-c         6.1.11            he025d50_1002    conda-forge
mysqlclient               1.4.6                    pypi_0    pypi
sqlalchemy                1.3.12           py37hfa6e2cd_0    conda-forge
sqlite                    3.30.1               hfa6e2cd_0    conda-forge
sqlparse                  0.3.0                      py_0    conda-forge
django                    3.0.2                    py37_0    conda-forge
django-classy-settings    2.1.1                    pypi_0    pypi
django-debug-toolbar      2.1                        py_0    conda-forge

我正在使用具有以下设置的 MySQL 数据库。该数据库是使用我公司内的 IT 云数据服务创建的。我下载了 SSL 证书并将它们放在我的 django 项目中。

 DATABASES = {
        'default': {
            'ENGINE': 'django.db.backends.mysql',
            'NAME': 'MyTestTVPVDb',
            'USER': 'MyTestTVPVDb_so',
            'PASSWORD': 'YYYYYYYYYYYYYYYYYYY',
            'HOST': 'XXXXXXXXXXXXXXXXXXXXXXX',
            'PORT': '3307',
            'OPTIONS': {
                'ssl': {
                    'ssl-ca': os.path.join(SSL_CERT_ROOT, 'ca_cert.pem'),
                }
            }
        }
    }

现在，当我输入时python manage.py dbshell，我可以正常连接到数据库，并且一切正常。我可以看到数据库支持 SSL。

但是，当我键入python manage.py runserver启动服务器时，我得到以下我不知道如何解决的异常。

如果我将mysqlclient包从 v1.4.6 降级到 v1.3.14，服务器启动正常。

任何想法这里出了什么问题？SSL证书有问题吗？
