The following code is a small program default landing, but the other how to judge whether the user login page? Not every page to write such a right,

 
//index. Js 
//get application example 
Const app=getApp ()

Data: {
Motto: 'Hello World', 
The userInfo: {}, 
HasUserInfo: false, 
CanIUse: wx. CanIUse (' button. The open - type. GetUserInfo ') 
}, 
//event handler 
BindViewTap: function () {
Wx. NavigateTo ({
url: '../logs/logs' 
}) 
}, 
OnLoad: function () {
If (app. GlobalData. The userInfo) {
Enclosing setData ({
The userInfo: app. GlobalData. The userInfo, 
HasUserInfo: true 
}) 
} else if (this. Data. CanIUse) {
//since getUserInfo is network request, may be on the Page. The onl oad before returning to 
//so I join the callback to prevent this kind of circumstance 
App. UserInfoReadyCallback=res=& gt; {
Enclosing setData ({
The userInfo: res. The userInfo, 
HasUserInfo: true 
}) 
} 
} else {
//in the absence of open - type=getUserInfo version compatibility processing 
Wx. GetUserInfo ({
Success: res=& gt; {
App. GlobalData. The userInfo=res. The userInfo 
Enclosing setData ({
The userInfo: res. The userInfo, 
HasUserInfo: true 
}) 
} 
}) 
} 
}, 
GetUserInfo: function (e) {
The console. The log (e) 
App. GlobalData. The userInfo=e.d etail. The userInfo 
Enclosing setData ({
