Question

我正在构建 json REST API 。我需要扩展验证库，为所有验证失败的json输出添加静态标记"error":"validation_failed"。

    // create the validation rules ------------------------
    $rules = array(
        'firstName'         =>  'required',
        'lastName'          =>  'required',
        'email'             =>  'required|email|unique:users', 
        'reg_type'          =>  'required|in:'.implode(",", $this->types),
        'oauthUId'          =>  'required_if:reg_type,'.implode(",", $this->externalTypes),
        'password'          =>  'required_if:reg_type,email',
        'parentId'          =>  'sometimes|integer|exists:user_accounts,id',
    );

    // do the validation ----------------------------------

    $validator = Validator::make(Input::all(), $rules);

    // check if the validator failed -----------------------

    if ($validator->fails()) {
        // get the error messages from the validator
        return $validator->messages();
    }
    else {
        // validation successful ---------------------------
    }

我检查了laravel / validator.php，发现它应该添加到Illuminate \ Support \ MessageBag对象中。

$this->messages->add($attribute, $message);

如何通过扩展验证器类来实现。

我需要像这样的输出json

{
"error":
"validation_failed",
"firstName":
"The first name field is required.",
"lastName":
"The last name field is required.",
"reg_type":
"The selected reg type is invalid."
}

您可能可以实现自己的验证器类并添加到它：

class MyValidator extends Validator {

    public function passes()
    {
        if ( ! $passes = parent::passes())
        {
            $this->addError('error', 'validation_failed', []);
        }

        return $passes;
    }

}

在laravel中向验证失败消息添加密钥
