正确的请求正文被 Go 中的验证器视为无效

Question

我正在尝试使用验证器根据此结构验证请求正文。但是在Postman中，在验证结构时，它总是会抛出错误。我只希望在提出请求时需要所有值。package modeltype User struct {    FeatureName string `json:"featureName" validate:"required"`    Email       string `json:"email" validate:"required"`    CanAccess   *bool  `json:"can_access" validate:"required"`}我已尝试将其作为Postman上的请求正文发送：// Request body{    "featureName": "crypto",    "email": "[e-mail]",    "can_access": true}// Response body{    "status": 422,    "message": "Missing parameters featureName/can_access/email"}法典：package controllerimport (    "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        }

validatorInstance:=validator.New()

validatorInstance.Struct(user)
