一、简要概述

扫码登录本质上是WhatsApp的多设备登录，设备之间可以独立运行，那么当我们首次通过WhatsApp扫码登录二维码时，到底发生了那些事情？交换了那些数据？下面我们来一一分析。

二、流程分析 1、设备新增

网页上你看到的二维码本质是一串字符串，类似这样的2@Z1vEcXIs2pVu2TXNnSm2M3GSQdS5VbnujYPgk7yRk357uJBHWcXgZxAq3tYsWYkLqScOgTKIVkdpIw==,5LCR7sLmRYEbIyruSadIYH7papJluPHeuW+MP7ID0g0=,98YjOiyooXXYnPMrR067bV7VwjkMdxj0ODihSahmYWk=,NQQNAuKalfLUvC9m5G/ejCDum7yIePRT3hXGUj6prsA

当手机端扫码时，其实会向服务器发送一个注册设备的包文：

2、状态同步

新增成功后那么得同步一些用户的设置，比如本地语音，通讯录，快捷回复等
