Preview

Install

  • 此 Package 必须开启 Cache 才能使用,应为验证码是保存在cache里面。
  • 由于5.8版本以上缓存存贮的时间单位从分钟变为秒,所以这边做了调整
composer require zjsy/captcha-lumen5

How to use

bootstrap/app.php中注册Captcha Service Provider:

    $app->register(zjsy\CaptchaLumen5\CaptchaServiceProvider::class);
    class_alias('zjsy\CaptchaLumen5\Facades\Captcha','Captcha');

Set

bootstrap/app.php中可以設定各種自定義類型的驗證碼屬性,更多詳細設定請查看 Captcha for Laravel 5

    'characters' => '2346789abcdefghjmnpqrtuxyzABCDEFGHJMNPQRTUXYZ',

    'useful_time' => 300, //驗證碼有效時間(秒)

    'login'   => [ //驗證碼樣式
        'length'    => 4, //驗證碼字數
        'width'     => 100, //圖片寬度
        'height'    => 44, //字體大小和圖片高度
        'angle'     => 10, //字體傾斜度
        'lines'     => 2, //橫線數
        'quality'   => 90, //品質
        'invert'    =>false, //反相
        'bgImage'   =>true, //背景圖
        'bgColor'   =>'#ffffff',
        'fontColors'=>['#339900','#ff3300','#9966ff','#3333ff'],//字體顏色
    ],

    'flat'   => [
        'length'    => 6,
        'width'     => 160,
        'height'    => 46,
        'quality'   => 90,
        'lines'     => 6,
        'bgImage'   => false,
        'bgColor'   => '#ecf2f4',
        'fontColors'=> ['#2c3e50', '#c0392b', '#16a085', '#c0392b', '#8e44ad', '#303f9f', '#f57c00', '#795548'],
        'contrast'  => -5,
    ],

    'mini'   => [
        'length'    => 3,
        'width'     => 60,
        'height'    => 32,
    ],

    'inverse'   => [
        'length'    => 5,
        'width'     => 120,
        'height'    => 36,
        'quality'   => 90,
        'sensitive' => true,
        'angle'     => 12,
        'sharpen'   => 10,
        'blur'      => 2,
        'invert'    => true,
        'contrast'  => -5,
    ]

如果不配置設定檔,默認就是default,驗證碼有效時限為5分鐘。

Example

因為 Lumen 都是無狀態的 API,所以驗證碼圖片都會綁上一個 UUID,先獲得驗證碼的 UUID 跟圖片的 URL,驗證時再一併發送驗證碼與 UUID。

Generate

獲得驗證碼:

{Domain}/captchaInfo/{type?}

type就是在 config 中定義的 Type,如果不指定type,默認為default樣式,Response:

{
  "captchaUrl": "http://{Domain}/captcha-image/login/782fdc90-3406-f2a9-9573-444ea3dc4d5c",
  "captchaUuid": "782fdc90-3406-f2a9-9573-444ea3dc4d5c"
}

captchaUrl為驗證碼圖片的 URL,captchaUuid為綁定驗證碼圖片的uuid。

validate

在發送 Request 時將驗證碼與 UUID 一併送回 Server 端,在接收參數時做驗證即可:

public function checkCaptcha(Request $request, $type = 'default',$captchaUuid)
    {
        $this->validate($request,[
            'captcha'=>'required|captcha:'.$captchaUuid
        ],[
            'captcha.required'=>'验证码不能为空!'
            'captcha.captcha'=>'验证码错误!'
        ]);
        ...
    }
