如何验证Go对象数据，如Javascript'；乔伊呢？

我使用JavaScript进行对象模式和数据验证。在Golang中，我知道如何进行模式验证，但如何进行数据验证

Golang是否有同等的Joi？我知道Godog，但它还没有达到1.0。

试试ozzo验证

这取决于，你想要什么。。。验证的上下文是什么？也许像Gobuffalo这样的框架可以帮助你。在将数据写入数据库之前，您是否进行了验证？或者是否要检查转储？查找

govalidator

package.@apxp我想在写入数据库或将其发送到其他组件之前验证收到的数据。你有什么建议？很好的提示，只是好奇使用这种验证的性能权衡。

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.
}
