PHP 打印扩展开发：从易联云到小鹅通的多驱动集成实践

目前已有易联云WIFI打印机扩展

扩展入口文件

文件目录 crmeb\services\printer\Printer.php

namespace crmeb\services\printer;use crmeb\basic\BaseManager;
use think\facade\Config;
use think\Container;/*** Class Printer* @package crmeb\services\auth* @mixin \crmeb\services\printer\storage\YiLianYun*/
class Printer extends BaseManager
{//...
}

使用打印扩展

use crmeb\services\printer\Printer;$printer = new Printer(['clientId'=>'','apiKey'=>'','partner'=>' ','terminal'=>'',
]);$res = $printer->setPrinterContent(['name'=> '标题','orderInfo'=> [],//订单信息'product'=> [],//商品信息
])->startPrinter();var_dump($res);

举例增加：小鹅通打印扩展

创建文件：crmeb\services\printer\storage\XiaoETong.php

namespace crmeb\services\printer\storage;class XiaoETong extends BasePrinter
{//初始化protected function initialize(array $config){}//开始打印public function startPrinter(){}//设置打印内容public function setPrinterContent(array $config): self{return $this;}}

增加小鹅通获取AccessToken

namespace crmeb\services\printer;class AccessToken extends HttpService
{/*** 获取token* @return mixed|null|string* @throws \Exception*/public function getAccessToken(){if (isset($this->accessToken[$this->name])) {return $this->accessToken[$this->name];}$action = 'get' . Str::studly($this->name) . 'AccessToken';if (method_exists($this, $action)) {return $this->{$action}();} else {throw new \RuntimeException(__CLASS__ . '->' . $action . '(),Method not worn in');}}//增加小鹅通获取access_token类protected function getXiaoETongAccessToken(){/** @var CacheServices $cacheServices */$cacheServices = app()->make(CacheServices::class);$this->accessToken[$this->name] = $cacheServices->getDbCache('XET_access_token', function () {//写获取$access_token的逻辑//...$access_token = '';return $access_token;}, 86400);if (!$this->accessToken[$this->name])throw new AdminException(400718);return $this->accessToken[$this->name];}}

使用小鹅通打印机

use crmeb\services\printer\Printer;$printer = new Printer('xiao_e_tong',['clientId'=>'',//小鹅通打印配置'apiKey'=>'',//小鹅通打印配置'partner'=>' ',//小鹅通打印配置'terminal'=>'',//小鹅通打印配置
]);$res = $printer->setPrinterContent(['name'=> '标题','orderInfo'=> [],//订单信息'product'=> [],//商品信息
])->startPrinter();var_dump($res);
