基本操作流程:\n\n**前置条件：对接API前，请务必先到开放平台(**[https://open.liankenet.com/](https://open.liankenet.com/#/device/detail?device_id=lc27cs03124305)**) 绑定设备，详见** [《重要通知：链科云设备安全性升级》](https://lianke.yuque.com/vgtche/ng6y25/gylb4owfwsn4che4?singleDoc#%E3%80%8A%E9%87%8D%E8%A6%81%E9%80%9A%E7%9F%A5%EF%BC%9A%E9%93%BE%E7%A7%91%E4%BA%91%E8%AE%BE%E5%A4%87%E5%AE%89%E5%85%A8%E6%80%A7%E5%8D%87%E7%BA%A7%E3%80%8B)\n\n1. **第一步-获取打印机信息**\n    \n    - 购买云盒，推荐使用链科云盒，[点击下单](https://shop167081082.m.youzan.com/v2/showcase/homepage?alias=W79JHvloAF)\n        \n    - 从二维码获取`deviceId`(云账号) 和 `deviceKey`(云密码)\n        \n2. **第二步-提交打印任务**\n    \n    - 设定打印机参数，并提交打印任务\n        \n3. **第三步-查询打印状态**\n    \n    - 查询打印结果（可使用回调代替）\n        \n\nAPI服务器地址 `cloud.liankenet.com`\n\n---\n\n`cloud.wisiyilink.com` **域名已下线，请及时更换，该域名随时失效** [点击查看更新变更通知详情](https://lianke.yuque.com/vgtche/ng6y25/vywmdxu20ghmysle?singleDoc=)\n\n## API约定\n\n- 每个请求的都要在headers中填入 ApiKey _**(重要, 如因不带ApiKey导致业务中断，链科不承担任何责任)**_\n    \n- ApiKey请到平台注册获取 [点击跳转](https://open.liankenet.com)\n    \n\n## 从二维码获取deviceId，deviceKey方法\n\n- 解析二维码获取网页链接，解析网页链接中token参数\n    \n- 得到token值进行反base64，得到以:分隔的字符串\n    \n- 字符串前者为deviceId，后者为deviceKey\n    \n\n## SDK (持续更新)\n\nphp sdk: [https://github.com/liankenet/cloud_printer_demo](https://github.com/liankenet/cloud_printer_demo)\n\n小程序配网插件：\n\n[https://mp.weixin.qq.com/wxopen/plugindevdoc?appid=wxa2a39810c572b508&token=1709758749&lang=zh_CN](https://mp.weixin.qq.com/wxopen/plugindevdoc?appid=wxa2a39810c572b508&token=1709758749&lang=zh_CN)\n\n## API 测试 demo\n\n[https://open.liankenet.com/api_demo/](https://open.liankenet.com/api_demo/#/home)\n\n## 注意事项（重要）\n\n- 请使用[https://docs.liankenet.com/api_doc/](https://docs.liankenet.com/api_doc/)获取最新文档，避免因版本更新遇到问题\n    \n- 有业务高峰期请提前通知，保障服务稳定性\n    \n- 该服务为正式对外服务，禁止对本API服务进行压测，如有压测行为视为攻击，链科有权禁用ApiKey与服务器ip，严重影响业务的攻击行为将通过法律途径解决\n    \n\n## 更新日志\n\n2022年03月01日\n\n- 打印接口新增`reportDeviceStatus` `reportPrinterStatus` `callbackUrl` 参数\n
