  • 写在前面:
  • 实现的逻辑是拍照上传调用后端封装好的身份证接口,然后同时调用七牛云接口把照片传过去以便后台管理系统审核看
  • 1:首选需要这么一张页面

图片描述

  • 接下来就写我是怎么做的

首先是布局(以下是wxml)

<view>
  <view class='idcard'>
    <image class="idcard_front" catchtap='uploadImageFront' src="{{idCardUrlFront}}"></image>
    <view class='idcard_front_desc'>扫描身份证人像面</view>
  </view>

  <view class='idcard'>
   <image class="idcard_front" catchtap='uploadImageBack' src="{{idCardUrlBack}}"></image>
    <view class='idcard_front_desc'>扫描身份证国徽面</view>
  </view>

  <view class="submit {{islogo?'logo_bg':'logo_disabled'}}" catchtap='submit'>下一步</view>
</view>

接着来写样式,要来就来全套不是,哈哈哈

/* pages/idcard/index.wxss */

.idcard {
  text-align: center;
  margin: 100rpx auto;
}
.logo_disabled {
  /* background: #FADFCB; */
  background: rgba(255, 173, 118, 0.40);
}

.logo_bg {
  background: #ffad76;
}

.idcard_front, .idcard_con {
  height: 370rpx;
  width: 580rpx;
}

.myCanvas {
  width: 600rpx;
  height: 450rpx;
  visibility: hidden;
  position: absolute;
}

.judgeCanvas {
  width: 2px;
  height: 2px;
  visibility: hidden;
}

.idcard_front_desc{
  font-size: 30rpx;
  color: #666666;
  margin-top: 20rpx;
}
.submit {
  height: 80rpx;
  width: 622rpx;
  line-height: 80rpx;
  border-radius: 40rpx;
  text-align: center;
  color: #fff;
  font-size: 32rpx;
  margin: 50rpx auto 40rpx;
  /* background: #ffad76; */
}

接着就是最重要的js了(我直接全选复制,各位见谅,封装的七牛云上传和wx.request在下面👇)
