ozzo 验证 v4 返回在结构中找不到字段 #0

在使用php中的Ozzo驗證v4時,可能會遇到一個常見的錯誤訊息:「ozzo 驗證 v4 傳回在結構中找不到欄位 #0」。這個錯誤提示表示驗證器在資料結構中無法找到指定的欄位。這可能是由於欄位名稱錯誤、資料結構不符或驗證規則設定錯誤等原因所引起的。在解決這個問題之前,我們需要仔細檢查程式碼和驗證規則,確保正確指定了欄位名稱並與資料結構相符。透過仔細排查和調試,我們可以輕鬆解決這個問題,讓程式碼順利運行。

問題內容

我正在使用 "github.com/go-ozzo/ozzo-validation/v4"。 這是我的結構:

type mystruct struct {
    uuid          string `json:"uuid"`
    firstuuid     string `json:"first_uuid"`
    seconduuid    string `json:"second_uuid"`
    thirduuid     string `json:"third_uuid"`
    phonenumber   string `json:"phone_number"`
    email         string `json:"email"`
    skypeid       string `json:"skype_id"`
    city          string `json:"city"`
    comment       string `json:"comment"`
    personnelid   string `json:"personnel_id"`
    firstdate     string `json:"first_date"`
    seconddate    string `json:"second_date"`
    firstboolean  bool   `json:"first_boolean"`
    secondboolean bool   `json:"second_boolean"`
}

這是驗證方法:

func (m mystruct) validate() error {
    err := validation.validatestruct(
        validation.field(&uui.personnelid, validation.match(personnelidregexp)),
        validation.field(&uui.uuid, is.uuid),
        validation.field(&uui.firstuuid, validation.required, is.uuid),
        validation.field(&uui.seconduuid, validation.required, is.uuid),
        validation.field(&uui.thirduuid, validation.required, is.uuid),
        validation.field(&uui.email, validation.required, is.email),
        validation.field(&uui.phonenumber, validation.required, validation.match(mobileregexp)),
        validation.field(&uui.city, validation.required),
        validation.field(&uui.comment),
        validation.field(&uui.skypeid, validation.required),
        validation.field(&uui.firstdate, validation.date(time.dateonly)),
        validation.field(&uui.seconddate, validation.date(time.dateonly)),
    )

    return err
}

這是我發送的請求:

{
    "uuid": "1e57ef49-352f-4545-a43a-b51cad6c5a0a",
    "phone_number": "09124567891",
    "email": "[email protected]",
    "skype_id": "some_skype_id",
    "city": "a city",
    "personnel_id": "",
    "comment": "no comment for now!",
    "first_date": "",
    "second_date": "",
    "first_uuid": "94038913-2bdb-4dde-99fb-640a24e1c003",
    "second_uuid": "7fa0e242-841b-4de0-a3ce-e2b54ecd1bca",
    "third_uuid": "35ab6711-852e-42c8-aab3-dfb901a845f5",
    "first_boolean": true,
    "second_boolean": false
}

我收到此錯誤:

field #0 cannot be found in the struct

解決方法

validatestruct 的第一個參數是 structptr:

func validatestruct(structptr interface{}, fields ...*fieldrules) error

您的程式碼中缺少此參數。不幸的是,編譯器無法捕獲此類錯誤。

這是修正後的實作(請注意,uui 也應該是 m):

func (m MyStruct) Validate() error {
    err := validation.ValidateStruct(
        &m,  // <== The first parameter is a pointer to the struct.
        validation.Field(&m.PersonnelID, validation.Match(personnelIDRegexp)),
        validation.Field(&m.UUID, is.UUID),
        validation.Field(&m.FirstUUID, validation.Required, is.UUID),
        validation.Field(&m.SecondUUID, validation.Required, is.UUID),
        validation.Field(&m.ThirdUUID, validation.Required, is.UUID),
        validation.Field(&m.Email, validation.Required, is.Email),
        validation.Field(&m.PhoneNumber, validation.Required, validation.Match(mobileRegexp)),
        validation.Field(&m.City, validation.Required),
        validation.Field(&m.Comment),
        validation.Field(&m.SkypeID, validation.Required),
        validation.Field(&m.FirstDate, validation.Date(time.DateOnly)),
        validation.Field(&m.SecondDate, validation.Date(time.DateOnly)),
    )

    return err
}
