          在項(xiàng)目開發(fā)過程中經(jīng)常會(huì)遇到需要唯一標(biāo)識(shí)碼的功能,風(fēng)信建站laravel開發(fā)項(xiàng)目使用ramsey/uuid包進(jìn)行唯一識(shí)別碼的應(yīng)用,分享經(jīng)驗(yàn)如下:

          安裝軟件包:
           
          composer require ramsey/uuid
           
          安裝過程如下:
          Using version ^3.8 for ramsey/uuid
          ./composer.json has been updated
          Loading composer repositories with package information
          Updating dependencies (including require-dev)
          Nothing to install or update
          Writing lock file
          Generating optimized autoload files
