对比数据库，打印，_id没错，timeTeam.time_stamp也没错，success执行成功，字段对应也没错

数据就是没有修改，全都没有修改

db.collection('appoint')

                .where({

                    _id: _id,

                    'timeTeam.time_stamp': _index,

                })

                .update({

                    data: {

                        'timeTeam.$.cycle': _cycle,

                        'timeTeam.$.end_time': _end,

                        'timeTeam.$.start_time': _start,

                        'timeTeam.$.peple': _peple,

                    },

                    success: res => {

                        wx.showToast({

                            title: '修改保存成功',

                            success: res => {

                                setTimeout(function () {

                                    wx.navigateBack({})

                                }, 1500)

                            }

                        })

                    }

                })
