--experimental-policy 标志可用于在加载模块时启用策略特性。

The --experimental-policy flag can be used to enable features for policies when loading modules.

Once this has been set, all modules must conform to a policy manifest file passed to the flag:

node --experimental-policy=policy.json app.js

The policy manifest will be used to enforce constraints on code loaded by Node.js.

To mitigate tampering with policy files on disk, an integrity for the policy file itself may be provided via --policy-integrity. This allows running node and asserting the policy file contents even if the file is changed on disk.

node --experimental-policy=policy.json --policy-integrity="sha384-SggXRQHwCG8g+DktYYzxkXRIkTiEYWBHqev0xnpCxYlqMBufKZHAHQM3/boDaI/0" app.js
