js程式碼：用 formSubmit來傳遞資料給後臺 我的是springboot後臺 如果未上傳到伺服器，url可以用  http://localhost:8080把資料傳給後臺

後臺接收：

Page({
  data: {
    pickerHidden: true,
    chosen: '',
    openid:''
  },
  onLoad: function () {
    this.getOpenid(); }, // 獲取使用者openid  getOpenid() { let that = this; wx.cloud.callFunction({ name: 'getOpenid', complete: res => { console.log('雲函式獲取到的openid: ', res.result.openId) var openid = res.result.openId; that.setData({ openid: openid }) } }) }, pickerConfirm: function (e) { this.setData({ pickerHidden: true }) this.setData({ chosen: e.detail.value }) }, pickerCancel: function (e) { this.setData({ pickerHidden: true }) }, pickerShow: function (e) { this.setData({ pickerHidden: false }) }, formSubmit: function (e) { var formData = e.detail.value; wx.request({ url: 'http://xxxx', data: formData, success: function (res) { console.log(res.data), wx.navigateTo({ url: '../mytickets/mytickets?code='+res.data+' ' }) } }) console.log('form發生了submit事件，攜帶資料為：', e.detail.value) }, formReset: function (e) { console.log('form發生了reset事件，攜帶資料為：', e.detail.value) this.setData({ chosen: '' }) }, qrcode: function (e) { wx.navigateTo({ url: '../../qrcode/qrcode' }) } })
