Correct request body is deemed to be invalid by validator in Go

I am trying to validate the request body according to this struct using validator. But in Postman it always throws an error when validating the struct. I just want all values to be required when making a request.

package model
type User struct {
FeatureName string `json:"featureName" validate:"required"`
Email       string `json:"email" validate:"required"`
CanAccess   *bool  `json:"can_access" validate:"required"`
}

I have tried sending this as the request body on Postman:

// Request body
{
"featureName": "crypto",
"email": "test5@gmail.com",
"can_access": true
}
// Response body
{
"status": 422,
"message": "Missing parameters featureName/can_access/email"
}

Code:

package controller
import (
"database/sql"
"encoding/json"
"errors"
"net/http"
"unicode/utf8"
"github.com/yudhiesh/api/model"
"gopkg.in/validator.v2"
"github.com/yudhiesh/api/config"
)
func InsertFeature(w http.ResponseWriter, r *http.Request) {
var user model.User
var response model.Response
db := config.Connect()
defer db.Close()
// Decode body into user struct
if err := json.NewDecoder(r.Body).Decode(&user); err != nil {
response.Message = "Error"
response.Status = http.StatusInternalServerError
json.NewEncoder(w).Encode(response)
return
} else {
// Validate struct to check if all fields are correct
// Fails here!
if err := validator.Validate(user); err != nil {
response.Message = "Missing parameters featureName/can_access/email"
response.Status = http.StatusUnprocessableEntity
json.NewEncoder(w).Encode(response)
return
} else {
// Execute insert statement to database
stmt := `INSERT INTO features (user_id, feature_name, can_access) SELECT id, ?, ? FROM users WHERE email=?`
if _, err = db.Exec(stmt, &user.FeatureName, &user.CanAccess, &user.Email); err != nil {
response.Message = "Error"
response.Status = http.StatusInternalServerError
json.NewEncoder(w).Encode(response)
return
} else {
response.Message = "Success"
response.Status = http.StatusOK
json.NewEncoder(w).Encode(response)
return
}
}
}
}

我看到你的代码中存在一个问题，你分享的链接是`https://github.com/go-playground/validator`，但是在代码中导入的是`gopkg.in/validator.v2`。如果你正在使用`go-playground validator`，请使用以下代码进行验证：
```go
import "github.com/go-playground/validator"
validatorInstance := validator.New()
validatorInstance.Struct(user)

import https://github.com/go-playground/validator
validatorInstance:=validator.New()
validatorInstance.Struct(user)
