对onShareAppMessage进行封装，分为分享到个人和分享到群
1.底层代码封装到util工具js里面
function onShareAppMessage(title, path, callback, imageUrl) { //设置一个默认分享背景图片 let defaultImageUrl = '../../images/share.jpg'; return { title: title, path: path, imageUrl: imageUrl || defaultImageUrl, success(res) { console.log("转发成功！"); if (!res.shareTickets) { //分享到个人 api.shareFriend().then(() = { console.warn("shareFriendSuccess!"); //执行转发成功以后的回调函数 callback && callback(); }); } else { //分享到群 let st = res.shareTickets[0]; wx.getShareInfo({ shareTicket: st, success(res) { let iv = res.iv let encryptedData = res.encryptedData; api.groupShare(encryptedData, iv).then(() = { console.warn("groupShareSuccess!"); //执行转发成功以后的回调函数 callback && callback(); }); } }); } }, fail: function (res) { console.log("转发失败！"); } };}//将其方法导出module.exports = { onShareAppMessage: onShareAppMessage}2.调用示例
/** * 用户点击右上角分享 */ onShareAppMessage: function (e) { let nickName = ''; try { nickName = getApp().globalData.userInfo.nickName; } catch (e) { console.warn("用户未授权！"); nickName = '有人'; } let title = `[${nickName}@我]帮我看看这个叫什么,经常吃却不知道名字`;; let path = '/pages/index/index'; let shareCallBack = () = { //分享成功后做的事情 // // }; //此处调用封装好的分享代码 return util.onShareAppMessage(title, path, shareCallBack); },
