The values obtained from initialization of other pages of the applet project are in two states. Other pages cannot get global cookie s under app.js global data

Overall situation

    session_id:null,

    telephone:null,
    is_vip:null,
    getInit:{},
  },

index.js page under other page files

Cookies cannot be printed out in onload or other life cycles. One is null and the other has value
An exclamation mark is displayed next to it: Value below was evaluated just now
But if you print, console.log(app.globalData.header.Cookie) will give you null But in the custom method, such as click to get the verification code, you can get the cookie value

In onLaunch, remove

To understand the life cycle of an applet, onLaunch is executed only once, and problems can occur if it is executed repeatedly. If you need to do other operations, you can put them in the callback. This involves the disgusting asynchrony of applets. You can learn about the applet life cycle and the promise of es6
