Solution: after Wechat updates the sharing interface, the original shareTicket directly in onShareAppMessage no longer exists. According to the latest documentation, it needs to be obtained in App.onLaunch () and App.onShow ().
Demo core code:
Index.js
Page ({
/ * *
* initial data of the page
, /
Data: {
OpenGid:''
}
/ * *
* Lifecycle function-- listen for page loading
, /
OnLoad: function (options) {
Let that = this
Wx.showShareMenu ({
WithShareTicket: true
})
App.getShareTiket (function (globalData) {
Console.log ('clickReload---globalData-- >' + JSON.stringify (globalData))
That.setData ({
OpenGid: globalData.openGid
})
})
}
ClickReload: function () {
Let that = this
App.getShareTiket (function (globalData) {
Console.log ('clickReload---globalData-- >' + JSON.stringify (globalData))
That.setData ({
OpenGid: globalData.openGid
})
})
}
})
Index.wxml
Group name: click to load the group name {{openGid? OpenGid: 'none'}} app.js
/ app.jsApp ({globalData: {shareTicket:', openGid:'}, onLaunch: function (options) {}, onShow: function (options) {let that = thisif (options & & options.scene = = 1044) {that.globalData.shareTicket = options.shareTicket} console.log ('onShow---options=--- >' + JSON.stringify (options))} GetShareTiket: function (cb) {let that = this// shows local storage capacity if (that.globalData.shareTicket) {wx.getShareInfo ({shareTicket: that.globalData.shareTicket) Success: function (res) {console.log ('getShareTiket---shareTicket-- >' + JSON.stringify (res)) let js_encryptedData = res.encryptedDatalet js_iv = res.ivwx.login ({success: function (res) {let js_code = res.codeconsole.log ('code-- >' + js_code) wx.request ({url: 'xxxxxxxx',method:' POST',data: {code: js_code,appId: 'xxxxx',encryptedData: js_encryptedData,iv: js_iv}) Success: function (res) {that.globalData.openGid = res.data.openGIdconsole.log ('getShareTiket---openGid' + that.globalData.openGid) typeof cb = = "function" & & cb (that.globalData)}, fail: function (err) {console.log (' getShareTiket---err' + JSON.stringify (err)}})} else {console.log ('shareTicket' does not exist)}}) Note
1: you must call this interface wx.showShareMenu ({withShareTicket: true}), otherwise you won't get shareTicket when App.onLaunch () and App.onShow ().
2: the Wechat developer tool can simulate 1044 of the scenarios, but the group name will not be displayed because you are not in the group. So when testing, pull a WeChat group, and then share to the test group, you can get the group name.
