一、前期准备工作

软件环境：微信开发者工具
官方下载地址：https://mp.weixin.qq.com/debug/wxadoc/dev/devtools/download.html

1、基本需求。

• 实现一维条码，二维码的快速生成

2、案例目录结构

二、程序实现具体步骤

1.条码index.wxml代码

<!--index.wxml-->
<view class="container page">
  <view class="panel">
    <view class="header">
    </view>
    <view class="barcode">
      <view class="barnum">{{code}}</view>
      <canvas canvas-id="barcode" />
    </view>
    <view class="qrcode">
      <canvas canvas-id="qrcode" />
    </view>
  </view>
</view>

2.条码index.wxss代码

/**index.wxss**/
page {
    background-color: #439057;
}

.page {
    display: flex;
    flex-direction: column;
    justify-content: center;
    align-items: center;
}

.container {
	padding-bottom: 10rpx;
}

.panel {
    display: flex;
    flex-direction: column;
    justify-content: space-between;
    align-items: stretch;
    box-sizing: border-box;
    width: 710rpx;
    margin-top: 40rpx;
    border-radius: 10rpx;
    background-color: #fff;
}

.header {
    height: 140rpx;
    background-color: #f0f0f0;
    border-radius: 10rpx 10rpx 0 0;
}

.barcode {
    display: flex;
    height: 320rpx;
    flex-direction: column;
    justify-content: center;
    align-items: center;
}

.barnum {
    width: 670rpx;
    height: 100rpx;
    line-height: 100rpx;
    font-size: 38rpx;
    font-weight: bold;
    text-align: center;
    letter-spacing: 10rpx;
    white-space: nowrap;
}

.barcode > canvas {
    width: 680rpx;
    height: 200rpx;  
}

.qrcode {
    height: 420rpx;
    display: flex;
    flex-direction: column;
    justify-content: flex-end;
    align-items: center;
}

.qrcode > canvas {
    width: 420rpx;
    height: 420rpx;
}

3.条码index.js逻辑代码

//index.js
var wxbarcode = require(\'../../utils/index.js\');

Page({

    data: {
        code: \'http://blog.geekxz.com\'
    },

    onLoad: function() {
        wxbarcode.barcode(\'barcode\', \'http://blog.geekxz.com\', 680, 200);
        wxbarcode.qrcode(\'qrcode\', \'http://blog.geekxz.com\', 420, 420);
    }
})
