访客 邀请奖励功能是直播软件源码中非常常见的功能之一，通过用户自身的社交关系网，为平台实现推广引流作用，今天就来讲讲，邀请功能的实现方式，最终效果图如下图所示：
一、直播软件源码中邀请功能的实现机制
用户在个人中心点击邀请奖励功能，打开功能页面，页面将展示用户的邀请码，点击复制按钮，可以把邀请码复制到剪贴板上发送给别人，也可点击右上角的分享按钮，弹窗分享弹窗，选择分享的渠道，将用户的名片分享在其他社交app中。
名片上有该用户邀请码和二维码。新用户方扫描二维码会打开app的下载链接，下载并注册登录app后会成为该用户的下级。新用户也可以在app首页的邀请码弹窗中手动输入对方的邀请码并成为对方的下级。
二、实现直播软件源码邀请功能的代码如下
