wx.cloud.callFunction({       name: 'login',       date: {},       success: res => {         console.log(res.result)         app.globalData.openid = res.result.openid         console.log(app.globalData.openid)       },     })     const db = wx.cloud.database()     db.collection('student').where({       _openid: app.globalData.openid     })       .get({         success: function (res) {           console.log(res.data.length)           if (res.data.length > 0) {             wx.navigateTo({               url: '../index1/index1',             })           }         },       }) 运行结果如下[图片]

代码像下面一样，目的是为了检测数据库有没有这个用户，如果有就跳过这个环节 const db = wx.cloud.database()     db.collection('student').where({       _openid: app.globalData.openid       })       .get({         success: function(res) {           console.log(res.date.lenght)           if (parseFloat(res.date.lenght) > 0) {             wx.navigateTo({               url: '../index1/index1',             })           }         },       })
