[图片] 后端需要连接到MySQL数据库，配置并启动代理后仍然无法连接，服务列表中有wxcloud-localdebug-proxy服务，请问如何解决

出现错误的地方如图： File "/root/.local/lib/python3.8/site-packages/django/conf/__init__.py", line 82, in __getattr__ self._setup(name) File "/root/.local/lib/python3.8/site-packages/django/conf/__init__.py", line 69, in _setup self._wrapped = Settings(settings_module) File "/root/.local/lib/python3.8/site-packages/django/conf/__init__.py", line 170, in __init__ mod = importlib.import_module(self.SETTINGS_MODULE) File "/usr/lib/python3.8/importlib/__init__.py", line 127, in import_module return _bootstrap._gcd_import(name[level:], package, level) File "<frozen importlib._bootstrap>", line 1014, in _gcd_import File "<frozen importlib._bootstrap>", line 991, in _find_and_load File "<frozen importlib._bootstrap>", line 975, in _find_and_load_unlocked File "<frozen importlib._bootstrap>", line 671, in _load_unlocked File "<frozen importlib._bootstrap_external>", line 848, in exec_module File "<frozen importlib._bootstrap>", line 219, in _call_with_frames_removed File "/app/wxcloudrun/settings.py", line 73, in <module> 'HOST': os.environ.get("MYSQL_ADDRESS").split(':')[0], AttributeError: 'NoneType' object has no attribute 'split' 检查了下对应的源代码 # Database # https://docs.djangoproject.com/en/3.2/ref/settings/#databases DATABASES = { 'default': { 'ENGINE': 'django.db.backends.mysql', 'NAME': os.environ.get("MYSQL_DATABASE", 'django_demo'), 'USER': os.environ.get("MYSQL_USERNAME"), 'HOST': os.environ.get("MYSQL_ADDRESS").split(':')[0], 'PORT': os.environ.get("MYSQL_ADDRESS").split(':')[1], 'PASSWORD': os.environ.get("MYSQL_PASSWORD"), 'OPTIONS': {'charset': 'utf8mb4'}, } } 问题可能就出在这里了 处理建议 尝试 重试 查看 服务日志 提交工单，并在 问题描述 中附上以下信息：环境id：prod-8gt1nmide947a7d5；服务名称：django-e640；版本：django-e640-006；状态：部署失败
