使用路径设置自定义启动器作为 VS 代码中的参数值（Flask - 证书路径）

Question

Visual Studio Code python setup tutorial 中有一个示例显示了如何设置 Flask。当我尝试提供自签名证书路径时，我的问题就开始了。我尝试添加以下配置：

    {
        "name": "Python: Flask",
        "type": "python",
        "request": "launch",
        "module": "flask",
        "env": {
            "FLASK_APP": "app.py"
        },
        "args": [
            "run",
            "--debugger",
            "--no-reload",
            "--host",
            "0.0.0.0",
            "--port",
            "4443",
            "--key",
            "${workspaceFolder}\viberbot\key.pem",
            "--cert",
            "${workspaceFolder}\viberbot\certificate.pem"
        ],
        "jinja": true
    },

我已尝试将 key/cert 提供为：

C:\\FULL_PATH\\TO\\FILE
C:/FULL_PATH/TO/FILE
'C:\FULL_PATH\TO\FILE'
\"C:\FULL_PATH\TO\FILE\"

而且我总是收到以下错误消息之一： Error: Invalid value for "--key": "--cert" must also be specified. 或 Error: Invalid value for "--key": File ""E:\Docs\learn_py\viberbot\key.pem"" does not exist.

这是 VS Code 扩展生成的确切命令：

cd e:\Docs\learn_py && cmd /C "set "FLASK_APP=app.py" && set "PYTHONIOENCODING=UTF-8" && set "PYTHONUNBUFFERED=1" && C:\Users\user\AppData\Local\Programs\Python\Python37\python.exe c:\Users\user.vscode\extensions\ms-python.python-2019.2.5558\pythonFiles\ptvsd_launcher.py --default --client --host localhost --port 50573 -m flask run --debugger --no-reload --host 0.0.0.0 --port 4443 --key E:\Docs\learn_py\viberbot\key.pem --cert E:\Docs\learn_py\viberbot\certificate.pem " Usage: python -m flask run [OPTIONS] Try "python -m flask run --help" for help.

Error: Invalid value for "--key": "--cert" must also be specified.

更新：按照 Brett 的建议进行更改后，我开始遇到另一个错误：

 * Serving Flask app "app.py"
 * Environment: development
 * Debug mode: off
Usage: python -m flask run [OPTIONS]

Error: Could not import "app".

我尝试将 app.py 更改为 ${workspaceFolder}\viberbot\app.py 或提供类似 /E/path/viberbot/app.py 的路径，但没有成功。

更新 2：我需要做 "FLASK_APP": "viberbot\app.py"

可能是因为教程中的示例与 VS Code 提供的默认示例相比已过时。尝试：

{
            "name": "Flask",
            "type": "python",
            "request": "launch",
            "module": "flask",
            "env": {
                "FLASK_APP": "app.py",
                "FLASK_ENV": "development",
                "FLASK_DEBUG": "0"
            },
            "args": [
                "run",
                "--no-debugger",
                "--no-reload",
                "--cert",
                "${workspaceFolder}\viberbot\certificate.pem",
                "--key",
                "${workspaceFolder}\viberbot\key.pem"
            ],
            "jinja": true
        }
