README

此Composer包用于Laravel创建唯一标识符，在本例中为PIN（个人识别码），适用于门锁等。每次代码执行时，至少返回一个符合以下条件的PIN

• The initial intention is that each PIN comprises of four numeric digits (e.g. “2845”),
• This package will not generate “obvious” numbers. This can be handled

通过编程方式考虑以下限制，但允许以后添加更多

-> Palindromes
    • Invalid examples include : 2332,5555 etc.

-> Sequential numbers
    • Invalid examples Include : 0123,1234,1235etc.

-> Repeating numbers
    • Invalid examples Include : 1115,7377 etc.

-> As an example, 4942 would be a PIN that passes these 3 restrictions.
    • This package will provide the PINs in an apparently random order.
    • This package will not repeat a PIN until all the preceding valid PINs have been utilised - even if the solution is stopped and started between PINs being returned.
    • You can specify the lenght of the pin e.g. 4, 6, 7, 12-digit pins. But the recommendation will be to not use a very big number.

支持

支持的PHP版本为 ^7.2.5 到 ^8.2
支持的Laravel版本为8+

安装

在项目的根目录下运行以下命令来安装pin-generator包

composer require ajaydev/pin-generator dev-main

成功下载此包后，将服务提供者添加到您的

<project_root>/config/app.php

此提供者数组中

'providers' => [
    // add this line in your providers array
    AjayDev\PinGenerator\PinGeneratorServiceProvider::class,
],

此行

AjayDev\PinGenerator\PinGeneratorServiceProvider::class,

使用

完成上述步骤后，您只需在控制器中使用此外观

use AjayDev\PinGenerator\PinGeneratorFacade;

然后

$pin = PinGeneratorFacade::generatePin(2);  #at the place of two you can pass your length as per your requirement by default it will be 4 if you remove 2

单元测试用例（可选）

如果您想运行并查看所有测试用例是否工作正常，可以在您的根项目目录中使用此命令。

php artisan test vendor/ajaydev/pin-generator/tests/PinGeneratorTest.php

就这样，您就可以开始了。
