1.1.在页面内定义buton
2.buttonopen-type='share'/button
3.2.需要在分享方法里面设置
4.wx.showShareMenu({
withShareTicket:true
5.});
6.3.在分享成功返回后调用微信获取群信息方法来获取必要的参数
7.if(res.from==='button'){//页面内转发
return{
title:"标题",
path:"pages/sqpage/sqpage",
success:function(res){
varshareTickets=res.shareTickets;
if(shareTickets.length==0){
returnfalse;
8.}
9.wx.getShareInfo({
shareTicket:shareTickets[0],
success:function(res){
console.log(res);
varencryptedData=res.encryptedData;
encryptedData=decodeURIComponent(encryptedData);//解密获取的encryptedData
variv=res.iv;
iv=decodeURIComponent(iv);//解密获取的iv
10.}
11.4.调用微信登录方法来获取code值然后和后台配合来解析出Gopenid
12.wx.login({
success:function(res){
varcode=res.code;
varsignature=signa.signaturetik('token='+token,'userAccessToken='+userAccessToken,'code='+code,'encryptedData='+encryptedData,'iv='+iv);
wx.request({
url:"------------",//写上你后台服务器路径（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);
}
})
}
13.})
14.5.整体流程效果
15.onShareAppMessage:function(res){
varthat=this;
wx.showShareMenu({
withShareTicket:true
});
16.if(res.from==='button'){
17.return{
18.title:"电力发布小程序",
19.path:"pages/sqpage/sqpage",
20.success:function(res){
21.console.log(res);
22.varshareTickets=res.shareTickets;
23.if(shareTickets.length==0){
24.returnfalse;
25.}
26.wx.getShareInfo({
27.shareTicket:shareTickets[0],
28.success:function(res){
29.console.log(res);
30.varencryptedData=res.encryptedData;
31.encryptedData=decodeURIComponent(encryptedData);
32.variv=res.iv;
33.iv=decodeURIComponent(iv);
34.vartoken=signa.tokenmake();
35.wx.login({
36.success:function(res){
37.varcode=res.code;
38.varsignature=signa.signaturetik('token='+token,'userAccessToken='+userAccessToken,'code='+code,'encryptedData='+encryptedData,'iv='+iv);
39.wx.request({
40.url:"后台服务器路径",//写上你后台服务器路径（用途：解析出Gopenid）
41.header:{
42.'content-type':'application/x-www-form-urlencoded'
43.},
44.method:'POST',
45.data:{'code':code,'encryptedData':encryptedData,"iv":iv,'userAccessToken':userAccessToken,'signature':signature,'token':token},
46.success:function(res){
47.console.log(res);
48.}
49.})
50.}
51.})
52.}
53.})
54.},
55.fail:function(){
56.}
57.}
