golang中单个数组中的多重响应

Question

我是 golang 的新手。我想得到多重结果的回应。我做了一些方法，但我需要改变那个

impartErrl := ph.profileService.ValidateSchema(gojsonschema.NewStringLoader(string(b)))
        if impartErrl != nil {
            ctx.JSON(http.StatusBadRequest, impart.ErrorResponse(impartErrl))
            return
        }

func (ps *profileService) ValidateSchema(document gojsonschema.JSONLoader) (errors []impart.Error) {
    result, err := gojsonschema.Validate(ps.schemaValidator, document)
    if err != nil {
        ps.SugaredLogger.Error(err.Error())
        return impart.ErrorResponse(
            impart.NewError(impart.ErrBadRequest, "unable to validate schema"),
        )
    }

    if result.Valid() {
        return nil
    }
    // msg := fmt.Sprintf("%v validations errors.\n", len(result.Errors()))
    msg := "validations errors"
    for i, desc := range result.Errors() {
        msg += fmt.Sprintf("%v: %s\n", i, desc)
        er := impart.NewError(impart.ErrValidationError, fmt.Sprintf("%s ", desc), impart.ErrorKey(desc.Field()))
        errors = append(errors, er)
    }
    return errors
}

func NewError(err error, msg string, args ...interface{}) Error {
    key := GetErrorKey(args...)
    return impartError{
        err: err,
        msg: msg,
        key: key,
    }
}

func ErrorResponse(err interface{}) []Error {
    var errorResponse []Error
    switch err.(type) {
    case Error:
        errorResponse = []Error{err.(Error)}
    case []Error:
        errorResponse = err.([]Error)
    default:
        errorResponse = []Error{
            NewError(ErrUnknown, fmt.Sprintf("%v", err)),
        }
    }
    return errorResponse
}

type Error interface {
    error
    HttpStatus() int
    ToJson() string
    Err() error
    Msg() string
}

现在我得到的输出是

[
    {
        "error": "validation error",
        "msg": "email: Does not match format 'email' ",
        "key": "email"
    },
    {
        "error": "validation error",
        "msg": "screenName: String length must be greater than or equal to 4 ",
        "key": "screenName"
    }
]

但我需要我的回应

{
     0 :{
            "error": "validation error",
            "msg": "email: Does not match format 'email' ",
            "key": "email"
        },
    1 : {
        "error": "unable to complete the request",
        "msg": "invalid screen name, must be alphanumeric characters only",
        "key": "screen_name"
    }

}

我怎样才能得到这些类型的响应。？因为在 ios 应用中解析响应 [] 时显示错误。所以我需要更改输出。

请帮助我。

ErrorResponse 函数应该 return 一个 map[int]Error 而不是 []Error。例如：

func ErrorResponse(err interface{}) map[int]Error {
    errorResponse := map[int]Error{}
    switch e := err.(type) {
    case Error:
        errorResponse[0] = e
    case []Error:
        for i, k := range e {
            errorResponse[i] = k
        }
    default:
        errorResponse[0] = NewError(ErrUnknown, fmt.Sprintf("%v", err))
    }
    return errorResponse
}
