DGIOT国内首家轻量级物联网开源平台——支持远程打印条码/二维码和一码设备全生命周期

[小迪导读]：在制造企业工厂数字化转型过程中,经常会碰到下面这些问题:

整体交互图

1. 在dgiot创建打印机产品

2. 安装打印机驱动（在打印机官方寻找）

本次实例的是得力DL-750W打印机，驱动下载地址：得力DL-750W条码打印机(白)-得力集团有限公司

3.把当前打印机设为默认打印机

4. 打开dgiot_dtu

5. 在平台打印机产品下建立对应实体打印机的设备

以dgiot_dtu的客户编号为设备地址

6. 桌面端使用dgiot_dtu进行与平台对接

用户只需填写对应红框中的数据就好了

登录用户是指平台产品详细里面的ID

服务器地址指的技术当前部署dgiot服务器的外网地址

客户编号是在设备详细里面的地址

7. 远程调用打印机

前端调用打印机低代码示例

{"type": "page","body": [{"tabs": [{"body": [{"id": "u:04459a03cf7c","api": {"url": "iotapi/amis/Device/parse_objectid","method": "get","adaptor": "return {\r\n \"status\":0,\r\n \"msg\":\"\",\r\n \"data\":response\r\n }","headers": {"store": "localStorage","dgiotReplace": "parse_objectid"}},"body": [{"id": "u:94629dd6e880","api": {"url": "iotapi/classes/Device/parse_objectid","method": "put","headers": {"store": "localStorage","dgiotReplace": "parse_objectid"},"requestAdaptor": "return{\r\n ...api,\r\n data:{\r\n profile:{\r\n...api.data\r\n }\r\n }\r\n}"},"body": [{"mode": "inline","name": "data","size": "","type": "input-text","label": "打印内容","disabled": false,"readOnly": false,"horizontal": {"left": 4,"right": 8,"leftFixed": ""},"validateApi": "","autoComplete": false},{"mode": "inline","name": "cmd","size": "","type": "input-text","label": "操作","disabled": false,"readOnly": false,"horizontal": {"left": 4,"right": 8,"leftFixed": ""},"validateApi": "","autoComplete": false}],"type": "form","title": "","submitText": "打印"}],"type": "form","title": "表单","submitText": ""}],"icon": "fa fa-slideshare","title": "设备信息"}],"type": "tabs"}]}COPY

在前端调用/iotapi/classes/Device/(打印机设备在数据库中的objectId)接口实现配置下发

这是下发内容

{

"cmd":"printer",

"data":"210B8784AA"

}

cmd: 是指定模式以来判断进行操作

data：是指内容
