微信小程序分享设置

开启转发

    wx.showShareMenu({
      withShareTicket: true,
      //shareAppMessage 发送朋友 shareTimeline发送朋友圈
      menus: ['shareAppMessage', 'shareTimeline']
    })

自定义转发内容

onShareAppMessage: function () {
    return {
      title: '自定义转发标题',
      path: 'index/index?id=123',
　　　 imageUrl:''
    }
  }

解密转发内容

onLaunch: function (iv) {
    console.log(iv)
    //判断是否为转发
    if (iv.shareTicket) {
      //获取转发内容
      wx.getShareInfo({
        shareTicket: iv.shareTicket,
        success: function (sha) {
          if (sha.encryptedData) {
            console.log(sha)
            //获取code换session_key
            wx.login({
              success(log) {
                if (log.code) {
                  wx.request({
                    url: 'http://dpuw.dev.com/uapi/wxAuto/wxMiniProgramOauth',
                    data: {
                      code: log.code,
                      from: 'miniprogram'
                    },
                    success(suc) {
                      console.log(suc.data)
                      if (suc.data.result.data.session_key) {
                        //解密转发消息
                        wx.request({
                          url: 'http://dpuw.dev.com/uapi/wxAuto/getEncryptedData',
                          data: {
                            iv: sha.iv,
                            encryptedData: sha.encryptedData,
                            sessionKey: suc.data.result.data.session_key
                          },
                          success(shadata) {
                            //转发消息
                            console.log(shadata.data)
                          }
                        })
                      }
                    }
                  })
                } else {
                  console.log('登录失败！' + log.errMsg)
                }
              }
            })
          }
        }
