PHP如何使用飞鹅小票打印机？PHP对接飞鹅小票打印机接口
2024-04-16 PHP案例 452 WGE
在开发业务中，有许多场景需要接入小票打印机，例如：餐饮、外卖、配送等，飞鹅打印机是我们常用的小票打印机之一，这篇文章简单讲讲PHP如何计入飞鹅打印机。
一、添加小票/标签打印机
<?php
// 飞鹅开放平台API用户
$user = "xxx";
$uKey = "xxx";
// 小票打印机底部SN设备码
$sn = "xxx";
// API接口
$apiUrl = "https://api.feieyun.cn/Api/Open/";
//$printerConten => 打印机编号sn(必填) # 打印机识别码key(必填) # 备注名称(选填) # 流量卡号码(选填)，多台打印机请换行（\n）添加新打印机信息，每次最多100台。
$printerContent = "sn1#key1#remark1#carnum1\nsn2#key2#remark2#carnum2";
$time = time();
$params = [
'user'=>$user,
'stime'=>$time,
'sig'=>sha1($user.$uKey.$time),
'apiname'=>'Open_printerAddlist',
'printerContent'=>$printerContent
];
$client = new HttpClient($apiUrl, 80);
if(!$client->post(apiUrl, $params )){
echo 'error';
}
$result = $client->getContent();
echo $result;
?>二、打印小票
// 飞鹅开放平台API用户
$user = "xxx";
$uKey = "xxx";
// 小票打印机底部SN设备码
$sn = "xxx";
// API接口
$apiUrl = "https://api.feieyun.cn/Api/Open/";
//根据打印纸张的宽度，自行调整内容的格式，可参考下面的样例格式
$content = '<CB>测试打印</CB><BR>';
$content .= '名称 单价 数量 金额<BR>';
$content .= '--------------------------------<BR>';
$content .= '饭 10.0 10 100.0<BR>';
$content .= '炒饭 10.0 10 100.0<BR>';

$content .= '西红柿蛋炒饭 10.0 10 100.0<BR>';

$content .= '订餐时间：2014-08-08 08:08:08<BR>';
$content .= '<QR>http://www.wge68.com</QR>';//把二维码字符串用标签套上即可自动生成二维码
$time = time();
$params = [
'user'=>$user,
'stime'=>$time,
'sig'=>sha1($user.$uKey.$time),
'apiname'=>'Open_printMsg',
'sn'=>$sn,
'content'=>$content,
'times'=>1, //打印次数
];
$client = new HttpClient($apiUrl, 80);
if(!$client->post(apiUrl, $params )){

$result = $client->getContent();
