又准备到国庆了,很多人又要开始换头像了,每到节日微信小程序换头像小程序流量都要大涨。
在网上经常看到很多国庆微信小程序换头像的,比如国庆节,圣诞节等节日头像框,一键换头像,其实原理很简单,就是微信小程序授权登陆后,获取你原始头像,在你选择国旗等头像后和你授权获取头像合并生成一张新头像,另存下载却可。
本源码采用ColorUI小程序框架,加了很多素材头像框架图,无后台接口,功能也很简单,只有一个页面。
其主要功能和逻辑:
授权获取微信头像
头像边框分类及边框图,所有边框图必须放在远程服务器,图片太大小程序不允许
选择切换头像功能,
小程序canvas生成图片保存
分享功能
加入视频广告点击,适合流量主,赚广告费。
先上图看效果:
<view class="wrapper"> <view class="container"> <image class="page-bg _img" mode="widthFix" src="{{bgImage}}"></image> <view class="avatar-container" style="{{'margin-top:'+(showHeight+'px')+';'}}" id="avatar-container"> <!-- 屏蔽上传iocn --> <!-- <block wx:if="{{avatarImage}}"> <view class="xiangji-icon"><label data-event-opts="{{[['tap',[['chooseImage',['$event']]]]]}}" class="iconfont iconxiangji2 _span" bindtap="__e"></label></view> </block> --> <image class="avatar-img _img" id="avatar-img" src="{{avatarImage}}"></image> <block wx:if="{{currentFrame}}"> <image class="avatar-frame _img" src="{{frameImage}}"></image> </block> <block wx:if="{{!avatarImage}}"> <view class="empty-avatar-view"> <image class="empty-avatar _img" src="/static/image/avatar_empty.svg"></image> <button class="cu-btn round action-btn btn-primary" id="btn-choose-img" bindtap="getUserProfile">获取头像</button> </view> </block> <view class="prev _p" wx:if="{{!avatarImage}}" bindtap="getUserProfile"><label class="iconfont iconqianfanicon _span"></label></view> <view class="next _p" wx:if="{{!avatarImage}}" bindtap="getUserProfile"><label class="iconfont iconhoufanicon _span"></label></view> <view class="prev _p" wx:if="{{avatarImage}}" data-type="pre" bindtap="cutover"><label class="iconfont iconqianfanicon _span"></label></view> <view class="next _p" wx:if="{{avatarImage}}" data-type="next" bindtap="cutover"><label class="iconfont iconhoufanicon _span"></label></view> </view> <view class="_div"><canvas class="canvas" canvasId="canvas"></canvas></view> <view class="panel assets-container"> <view style="display:flex;" clss="category-list" class="_div"> <block wx:for="{{categoryList}}" wx:for-item="item" wx:for-index="index" wx:key="index"> <view class="_div"><text class="{{['category ',item.id===currentCategory?'active':'']}}" data-categroy-id="{{item.id}}" bindtap="imageListTab">{{item.name}}</text></view> </block> </view> <scroll-view class="assets-scroll-view" scroll-into-view="{{bottomId}}" scrollX="true"> <block wx:for="{{imageList}}" wx:for-item="item" wx:for-index="index" wx:key="index"> <view class="{{['assets','_div',index===savedNum&&avatarImage?'active-border':'']}}" id="{{'img'+index}}"> <image src="{{item.src}}" data-index="{{index}}" data-src="{{item.src}}" bindtap="selectAvatarImage" class="_img"></image> </view> </block> </scroll-view> </view> <view class="flex justify-around"> <button class="cu-btn round action-btn" openType="share" id="btn-choose-img" bindtap="share">分享给朋友</button> <button class="cu-btn round action-btn btn-primary" id="btn-save" bindtap="saveCans">保存到相册</button></view> <view class="ad-container"> <view binderror="__e" bindload="__e" unitId="adunit-43f7c4189a8e7c35" class="_div"></view> </view> </view> </view>
