使用mysql模块时，ssl: true是否为MySQL SSL连接的有效选项？

Great question! Let me break this down clearly for you:

First off, yes, ssl: true is indeed a valid option even though the official documentation only explicitly mentions string or object types. Here's why:

• The mysql module has internal logic that handles boolean values for the ssl option. When you pass ssl: true, the module automatically enables SSL using its built-in default configuration. This includes using a pre-packaged CA certificate to verify the MySQL server's identity, which works for most standard setups (like connecting to managed MySQL services or servers using widely trusted certificates).

• To contrast with the other allowed types:

  • A string value should point to the path of a PEM-formatted certificate file, which the module uses for verification.
  • An object lets you fully customize SSL settings (e.g., specifying custom ca, cert, key files, disabling certificate verification with rejectUnauthorized: false, etc.).

The reason your code works without issues is that the module silently handles the boolean true case by falling back to those sensible defaults. The documentation might be incomplete here—sometimes official docs don't cover every edge case or implicit behavior that's implemented in the codebase.

If you want to confirm this, you could check the module's source code: you'll find that when the ssl option is set to true, it initializes an SSL context with the default CA bundle included with the module.
