我使用Joi在 JavaScript 中執(zhí)行對象模式和數(shù)據(jù)驗證。在 Golang 中，我知道如何進行模式驗證，但我如何進行數(shù)據(jù)驗證？Golang 是否有 Joi 等價物？我知道 Godog，但它還沒有達到 1.0。

嘗試 ozzo-validation?
package main
import (
? ? "fmt"
? ? "regexp"
? ? "github.com/go-ozzo/ozzo-validation"
? ? "github.com/go-ozzo/ozzo-validation/is"
)
type Address struct {
? ? Street string
? ? City? ?string
? ? State? string
? ? Zip? ? string
}
func (a Address) Validate() error {
? ? return validation.ValidateStruct(&a,
? ? ? ? // Street cannot be empty, and the length must between 5 and 50
? ? ? ? validation.Field(&a.Street, validation.Required, validation.Length(5, 50)),
? ? ? ? // City cannot be empty, and the length must between 5 and 50
? ? ? ? validation.Field(&a.City, validation.Required, validation.Length(5, 50)),
? ? ? ? // State cannot be empty, and must be a string consisting of two letters in upper case
? ? ? ? validation.Field(&a.State, validation.Required, validation.Match(regexp.MustCompile("^[A-Z]{2}$"))),
? ? ? ? // State cannot be empty, and must be a string consisting of five digits
? ? ? ? validation.Field(&a.Zip, validation.Required, validation.Match(regexp.MustCompile("^[0-9]{5}$"))),
? ? )
}
func main() {
? ? a := Address{
? ? ? ? Street: "123",
? ? ? ? City:? ?"Unknown",
? ? ? ? State:? "Virginia",
? ? ? ? Zip:? ? "12345",
? ? }
? ? err := a.Validate()
? ? fmt.Println(err)
? ? // Output:
? ? // Street: the length must be between 5 and 50; State: must be in a valid format.
