lumen验证总结

一、参数验证，拒绝if...else对参数的校验

1、根据接口返回规则

{
    "code": 1062,
    "message": "参数错误"
}

方法一：model方法验证

新建基础控制器HttpBaseController

all(), $rule, $message);
            if($validator->fails()){
                foreach($validator->errors()->getMessages() as $message){
                    $sys_err = config('sys_error.sys_error');
                    if(is_array($message[0])){
                        return json_encode($response);
                    }
                    $this->code = $message[0];
                    if (!isset($sys_err[$this->code])) {
                        $response = [
                            'code' => 1062,
                            'message' => $message[0] ?? '参数错误',
                        ];
                        return json_encode($response);
                    }
                    return re_err($message[0]);
                }
            }
            return null;
        }catch (\Exception $e){
            throw_err(501);
        }
    }
}

2、类的使用，控制器继承这个基础类

如 DistributeBaseController
类的继承 class DistributeBaseController extends HttpBaseController

3、验证方法使用
使用验证规则放在Model中的方法里

 'required|regex:/^[a-zA-Z][a-zA-Z0-9]{5,11}$/',
            'email' => 'required|email',
            'password' => 'required|min:6',
            'old_password' => 'required|min:6',
            'mobile_no' => 'required|numeric|digits:11',
        ];
        foreach ($array as $item) {
            $data[$item] = $rules[$item];
        }
        return $data;
    }

    public function message()
    {
        return [
            'username.required' => '1062',
            'username.unique' => '用户名已存在',
            'username.regex' => '用户名不合法',
            'email.required' => '请填写邮箱地址',
            'email.unique' => '邮箱名已存在',
            'email.email' => '邮箱名不合法',
            'password.required' => ['code'=>'1062','message'=>'请填写密码'],
            'password.min' => '密码至少需要 :min 位字符',
            'mobile_no.required' => '请填写手机号',
            'mobile_no.unique' => '手机号已存在',
            'mobile_no.numeric' => '手机号必须为数字',
            'mobile_no.digits' => '手机号必须为 :digits 位',
        ];
    }
}

调用
        $user = new TestModel();
        $validator_user = $this->ruleValidator(
            $this->request,
            $user->rules(['username', 'password']),
            $user->message());
        if ($validator_user) {
            return $validator_user;
        }

方法二：临时验证

1、重写验证抛错方法throwValidationException

code = $validator->errors()->first();

        if (!isset($sys_err[$this->code])) {
            $response = [
                'code' => 1062,
                'message' => $this->code ?? '参数错误',
            ];
            throw new ValidationException($validator, $response);
        }
        if ($this->message == '') {
            $message = $sys_err[$this->code];
        }
        $response = [
            'code' => $validator->errors()->first(),
            'message' => $message,
        ];

        throw new ValidationException($validator, $response);
    }
}

2、类的使用，控制器继承这个基础类

如 DistributeBaseController
类的继承 class DistributeBaseController extends HttpBaseController

3、控制器使用

       $this->validate($this->request, [
            'title' => 'required|max:255',
            'mobile' => 'required|numeric|digits:11'
        ], [
            'title.required' => '标题错误',
            'mobile.required' => '请填写手机号',
            'mobile.unique' => '手机号已存在',
            'mobile.digits' => '手机号必须为 :digits 位',
        ]);
