小程式頁面內轉發到群並獲取微信群標識
1.首先需要在分享方法裡面設定
wx.showShareMenu({
withShareTicket: true
});
2.在分享成功返回後呼叫微信獲取群資訊方法來獲取必要的引數
if (res.from === 'button') {//頁面內轉發
return {
title: "標題",
path: "pages/sqpage/sqpage",
success: function (res) {
var shareTickets = res.shareTickets;
if (shareTickets.length == 0) {
return false;
}
wx.getShareInfo({
shareTicket: shareTickets[0],
success: function (res) {
console.log(res);
var encryptedData = res.encryptedData;
encryptedData = decodeURIComponent(encryptedData);//解密獲取的encryptedData
var iv = res.iv;
iv = decodeURIComponent(iv);//解密獲取的iv
}
3.呼叫微信登入方法來獲取code值然後和後臺配合來解析出Gopenid
wx.login({
success: function (res) {
var code = res.code;
var signature = signa.signaturetik('token=' + token, 'userAccessToken=' + userAccessToken, 'code=' + code, 'encryptedData=' + encryptedData, 'iv=' + iv);
wx.request({
url: "------------",//寫上你後臺伺服器路徑（用途：解析出Gopenid）
header: {
'content-type': 'application/x-www-form-urlencoded'
},
method: 'POST',
data: { 'code': code, 'encryptedData': encryptedData, "iv": iv, 'userAccessToken': userAccessToken, 'signature': signature, 'token': token},
success: function (res) {
console.log(res);
}
})
}
})
4.整體流程效果
onShareAppMessage: function (res) {
console.log(res);
var that = this;
wx.showShareMenu({
withShareTicket: true
});
if (res.from === 'button') {
return {
title: "電力釋出小程式",
path: "pages/sqpage/sqpage",
success: function (res) {
console.log(res);
var shareTickets = res.shareTickets;
if (shareTickets.length == 0) {
return false;
}
wx.getShareInfo({
shareTicket: shareTickets[0],
success: function (res) {
console.log(res);
var encryptedData = res.encryptedData;
encryptedData = decodeURIComponent(encryptedData);
var iv = res.iv;
iv = decodeURIComponent(iv);
var token = signa.tokenmake();
wx.login({
success: function (res) {
var code = res.code;
var signature = signa.signaturetik('token=' + token, 'userAccessToken=' + userAccessToken, 'code=' + code, 'encryptedData=' + encryptedData, 'iv=' + iv);
wx.request({
url: "後臺伺服器路徑",//寫上你後臺伺服器路徑（用途：解析出Gopenid）
header: {
'content-type': 'application/x-www-form-urlencoded'
},
method: 'POST',
data: { 'code': code, 'encryptedData': encryptedData, "iv": iv, 'userAccessToken': userAccessToken, 'signature': signature, 'token': token},
success: function (res) {
console.log(res);
}
})
}
})
}
})
},
fail: function () {
}
}
}
}
