利用Vue生成二维码

Author：kak

         vue有两种生成二维码的方式，qrcode、vue-qr（有icon）；

1、qrcode

npm ``install` `--save qrcodejs2
//所需页面导入
import QRCode from 'qrcodejs2'

<div class="qrcode" ref="qrCodeUrl"></div>
<script>
import QRCode from 'qrcodejs2'
export default {
  data() {
    return {
  },
  methods: {
    creatQrCode() {
        var qrcode = new QRCode(this.$refs.qrCodeUrl, {
            text: 'https://blog.csdn.net/weixin_42601136', // 需要转换为二维码的内容
            width: 100,
            height: 100,
            colorDark: '#000000',
            colorLight: '#ffffff',
            correctLevel: QRCode.CorrectLevel.H
        })
    },
},
mounted() {
    this.creatQrCode();
},
};
</script>

2、vue-qr

可以增加icon

npm install vue-qr --save
import vueQr from 'vue-qr'

<vue-qr :logoSrc="imageUrl" text="https://blog.csdn.net/weixin_42601136" :size="200"></vue-qr>
 
<script>
    export default {
        name: "qecode",
        data() {
            return {
                imageUrl: require("../img/logo.png"),//icon路径
            }
        },
        components: {
            vueQr
        },
    },
}
</script>

    creatQrCode() {
      var qrcode = new QRCode(this.$refs.qrCodeUrl, {
        text: "https://blog.csdn.net/weixin_42601136", // 需要转换为二维码的内容
        width: 100,
        height: 100,

        colorLight: "#ffffff",
        correctLevel: QRCode.CorrectLevel.H,
      });
    },
  },
  mounted() {
    this.creatQrCode();
  },
