常见的想当然

Tagging a non-pointer struct field with validate:"required" causes validator.New().Struct() to reject an uninitialized zero-value struct.

这是本样本作者记下的、开发者或模型在此处通常会有的预期。下面的契约才是真正运行过的东西。

契约

• validator.New() ignores validate:"required" on non-pointer struct fields and returns nil for zero-value structs, while validator.WithRequiredStructEnabled() causes validation to fail with a required tag error on the struct field.
• Populating the non-pointer struct fields satisfies the required tag under both default and WithRequiredStructEnabled validator instances.
• Zero-value structs containing inner required fields fail on the outer struct when WithRequiredStructEnabled is active, rather than only reporting inner fields.
