- 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
首先是布局(以下是wxml)
扫描身份证人像面
扫描身份证国徽面
下一步
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)
