How to obtain microbused microfinder user position permissions (reminded)

WeChat applet has three ways to obtain the current location of the user:

1. WX.GetLocation with wx.openLocation)

Gets current accuracy, latitude, speed. No authorization is required. When Type is set to GCJ02, returning to the coordinate

2. Wx.chooselocation

An authorization is required to open the map selection position

There are three types:


1. wx.get setting

Obtaining the current setting of the user, only the apparatus has been requested to request the user in the return value, similar to the sample

initiate an authorization request to the user in advance. After calling, you will immediately pop up the window asking if the user agrees to authorize the applet to use a certain work.Or you can obtain some data users, but does not actually call the corresponding interface. If you have consent, does not popups appear directly before the user returns success. , Might look like

This is what wx.authorize appears

the question is: If I were the first time wx.chooseLocation () get permission denied, then use the wx.getSetting ()

to reacquire the rights of the how to do it?

thinking: wx.chooseLocation () There are methods fail, if after the first refusal, subsequent calls to select the map are triggered by this, then I can be in there fail method, using wx.getSetting ()

, so that every time it is determined whether a given permission.

The first step: Because there are multiple possible ways of using the positioning will be, so I wrote App.js positioning method, the easy call
   App ({// get the user's geolocation permissions getPermission: function (obj) {wx.chooseLocation ({success: function (res) {obj.setData ({addr: res.address // successfully invoked directly address})} , fail: function () {wx.getSetting ({success: function (res) {var statu = res.authSetting; if (statu [ 'scope.userLocation']) {wx.showModal ({title:! 'whether the current authorization Location',Content: 'Need to get your location, please confirm the authorization, otherwise the map function will not be available', success: function (tip) {wx.openSetting ({Success: function (data) {ix ({Success: function (data) {ix {i Data.authSetting ["Scope.userLocation"] === True) {wx.showtoast ({Title: 'Authorized Success', Icon: 'Success', Duration: 1000} // Remove the Chooselocation Selection Place WX.chooselocation ({success) {Obj.SetData ({addr: res.address})}},})} else {wx.showtoast ({Title: 'authorized failed ", icon:' Success', DURATION : 1000})}}}}}}}}}}, fail: function (res) {wx.showtoast ({Title: 'Call Authorization Window Failed ", icon:' Success', Duration: 1000})}}})}}}}}}}}) 


In the second step: in the page that needs to get the address:

VAR App = getApp (); Page ({DATA : {Addr: ‘Please select location’}, // Select Get Geographic Location GetDress: Function () {var That; App.getPermission (That); // Incoming That value can be directly set directly to the app.js page },})
   Final rendering: 

The position of the last position acquired on the phone is not large .

Update WX.OpenSetting precautions.

After the version 2.3.0, after the user has a click behavior, it can jump open the setting page, and the authorization information

is 2.3.0, I passed the above WX.ShowModal. The callback function calls wx.openSetting will happen the following error:

OpenSetting: Fail Can Only Be Invoked by UserTAP GESTURE.

But I test 2.2.4 until 2.3.1 will appear above.

2.3.2 and above will not have this problem. . . . . . . .

And when I test 2.0.8 to 2.2.3, the following error occurs. . . . . .

There is no such problem. Do not understand. . .
