68 阅读 0 评论
我是靠谱客的博主 重要战斗机，最近开发中收集的这篇文章主要介绍PHP易联云打印机实现打印小票，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

开发文档地址:开发文档地址
各编程语言SDK:
pythonSDK
phpSDK
javaSDK
goSDK
C#SDK
nodejsSDK

本文档用PHP语言,简要说明使用方式
首先下载php的SDK,放到extend目录下,修改各个文件的命名空间
在这里插入图片描述
在这里插入图片描述
其余的内容暂时不需要改
接下来创建model文件,放在commonmodel目录下,代码如下

<?php


namespace appcommonmodel;


use printsApiPrinterService;
use printsApiPrintService;
use printsConfigYlyConfig;
use printsOauthYlyOauthClient;
use thinkDb;
use thinkException;

class YLPrint
{
    //调用打印机
    public function callPrint($content)
    {
        $config = Db::name('print_config')->find();

        $app_id = $config['app_id'];
        $app_secret = $config['app_secret'];
        $terminal_no = $config['terminal_no'];
        $terminal_secret = $config['terminal_secret'];

        $map[] = ['time','gt', time()];
        //由于每日只有20次机会获取授权,因此要access_token存到表中,当过期时间大于当前时间,可以直接使用,否则就更新
        $print_token = Db::name("print_token")->where($map)->find();

        $config = new YlyConfig($app_id, $app_secret);

        if ($print_token) {
            $access_token = $print_token['access_token'];

附上表结构

```sql
CREATE TABLE `meet_print_token`  (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `access_token` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL,
  `refresh_token` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL,
  `create_time` datetime(0) NULL DEFAULT NULL COMMENT '创建时间',
  `expire_time` datetime(0) NULL DEFAULT NULL COMMENT '有效期',
  `time` int(11) NULL DEFAULT NULL COMMENT '过期时间',
  PRIMARY KEY (`id`) USING BTREE
) ENGINE = InnoDB AUTO_INCREMENT = 2 CHARACTER SET = utf8 COLLATE = utf8_general_ci COMMENT = 'token表' ROW_FORMAT = Compact;

CREATE TABLE `meet_print_config`  (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `app_id` int(11) NOT NULL,
  `app_secret` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL,
  `terminal_no` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL,
  `terminal_secret` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL,
  PRIMARY KEY (`id`) USING BTREE
) ENGINE = InnoDB AUTO_INCREMENT = 2 CHARACTER SET = utf8 COLLATE = utf8_general_ci COMMENT = '打印机配置表' ROW_FORMAT = Compact;

CREATE TABLE `meet_print_log`  (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `content` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL,
  `create_time` datetime(0) NOT NULL,
  PRIMARY KEY (`id`) USING BTREE
) ENGINE = InnoDB AUTO_INCREMENT = 8 CHARACTER SET = utf8 COLLATE = utf8_general_ci COMMENT = '打印日志表' ROW_FORMAT = Compact;
