thinkphp6: 用validate驗證參數合法性(thinkphp 6.0.9/php 8.0.14)

一，代碼：創建兩個validate

1，驗證商品列表

創建一個validate

liuhongdi@lhdpc:/data/php/admapi$ php think make:validate GoodsList
Validate:app\validate\GoodsList created successfully.

validate/GoodsList.php

<?php
declare (strict_types = 1);
 
namespace app\validate;
 
use think\Validate;
 
class GoodsList extends Validate
{
    /**
     * 定義驗證規則
     * 格式：'字段名' =>  ['規則1','規則2'...]
     *
     * @var array
     */
    protected $rule = [
        'categoryId'  => 'require|integer|gt:0',
        'channelId'  => 'require|length:4|alphaNum',
    ];
 
    /**
     * 定義錯誤信息
     * 格式：'字段名.規則名' =>  '錯誤信息'
     *
     * @var array
     */
    protected $message = [
        'categoryId.require' => '分類id必須',
        'categoryId.integer'     => '分類id需要是整數',
        'categoryId.gt'     => '分類id需大於0',
        'channelId.require' => '頻道id必須',
        'channelId.length'     => '頻道id長度不為4',
        'channelId.alphaNum'     => '頻道id需由字母和數字構成',
    ];
}

2，驗證登錄

創建validate

liuhongdi@lhdpc:/data/php/admapi$ php think make:validate Login
Validate:app\validate\Login created successfully.

validate/Login.php

<?php
declare (strict_types = 1);
 
namespace app\validate;
 
use think\Validate;
 
class Login extends Validate
{
    /**
     * 定義驗證規則
     * 格式：'字段名' =>  ['規則1','規則2'...]
     *
     * @var array
     */
    protected $rule = [
        'username'  => 'require|min:6|max:25',
        'password'  => 'require|min:6|max:10',
    ];
 
    /**
     * 定義錯誤信息
     * 格式：'字段名.規則名' =>  '錯誤信息'
     *
     * @var array
     */
    protected $message = [
        'username.require' => '用戶名必須',
        'username.min'     => '用戶名最少不能低於6個字符',
        'username.max'     => '用戶名最多不能超過25個字符',
        'password.require' => '密碼必須',
        'password.min'     => '密碼最少不能低於6個字符',
        'password.max'     => '密碼最多不能超過25個字符',
    ];
}

二，代碼：創建一個controller

1,創建controller

liuhongdi@lhdpc:/data/php/admapi$ php think make:controller Auth
Controller:app\controller\Auth created successfully.

代碼：

<?php
declare (strict_types = 1);
 
namespace app\controller;
 
use think\Request;
use app\result\Result;
use think\response\Json;
use app\validate\Login as LoginValidate;
use app\validate\GoodsList as GoodsListValidate;
use think\exception\ValidateException;
 
class Auth
{
    /**
     * 商品列表
     *
     * @return \think\Response
     */
    public function goodsList():Json {
        try {
            //echo "begin check:<br/>";
            validate(GoodsListValidate::class)
                //->scene('edit')
                ->check($_GET);
        } catch (ValidateException $e) {
            // 驗證失敗 輸出錯誤信息
            //echo "get error:<br/>";
            //var_dump($e->getError());
            return Result::Error(422,$e->getError());
        }
 
        $data = [
        ['id'=>"1",'name'=>"牙刷"],
        ['id'=>"2",'name'=>"杯子"],
        ];
        return Result::Success($data);
    }
 
 
    /**
     * 登錄
     *
     * @return \think\Response
     */
    public function login():Json {
        try {
            //echo "begin check:<br/>";
            validate(LoginValidate::class)
                //->scene('edit')
                ->check($_POST);
        } catch (ValidateException $e) {
                // 驗證失敗 輸出錯誤信息
                //echo "get error:<br/>";
                //var_dump($e->getError());
                return Result::Error(422,$e->getError());
        }
 
        if ($_POST["username"] == "dddddd" && $_POST["password"] == "111111"){
            //echo "success:<br/>";
            return Result::Success("success");
        } else {
            //echo "error:<br/>";
            return Result::Error(422,"用戶名密碼錯誤");
        }
    }
}
