你js文件里写这个没有

/* 页面转发 */

onShareAppMessage: function (res) {

    if (res.from === ‘button’) {

        // 来自页面内转发按钮

        console.log(res.target)

    }

    return {

        path: ‘/pages/index/index’,

        success: function (res) {

        // 转发成功

        console.log(res)

        },

        fail: function (res) {

        // 转发失败

        console.log(“转发失败”)

        }

    }

},
