Vue3使用vue-qrcode-reader實(shí)現(xiàn)掃碼綁定設(shè)備功能(推薦)

更新時(shí)間：2024年10月21日 10:02:55 作者：魚是一只魚啊

本文介紹了在Vue3中使用vue-qrcode-reader版本5.5.7來實(shí)現(xiàn)移動(dòng)端的掃碼綁定設(shè)備功能,用戶通過掃描二維碼自動(dòng)獲取設(shè)備序列號(hào),并填充到添加設(shè)備界面,完成設(shè)備綁定的全過程,包含ScanCode.vue和DeviceAdd.vue兩個(gè)主要界面的實(shí)現(xiàn)方式

需求描述

移動(dòng)端進(jìn)入網(wǎng)站后，登錄網(wǎng)站進(jìn)入設(shè)備管理界面。點(diǎn)擊添加設(shè)備，可以選擇直接添加或者掃一掃。點(diǎn)擊掃一掃進(jìn)行掃描二維碼獲取設(shè)備序列號(hào)自動(dòng)填充到添加設(shè)備界面的序列號(hào)輸入框中。然后點(diǎn)擊完成進(jìn)行設(shè)備綁定。

安裝vue-qrcode-reader 這里使用的版本是5.5.7

npm install vue-qrcode-reader --save
