微信小程序工具函数封装

Posted in Javascript onOctober 28, 2019

本文实例为大家分享了微信小程序工具函数封装的具体代码，供大家参考，具体内容如下

const formatTime = date => {
 const year = date.getFullYear()
 const month = date.getMonth() + 1
 const day = date.getDate()
 const hour = date.getHours()
 const minute = date.getMinutes()
 const second = date.getSeconds()
 return [year, month, day].map(formatNumber).join('/') + ' ' + [hour, minute, second].map(formatNumber).join(':')
}
 
const formatNumber = n => {
 n = n.toString()
 return n[1] ? n : '0' + n
}

}
 
function jiamiParams(obj) {

 var newKey = Object.values(obj);
 
 for (var i = 0; i < newKey.length; i++) {
 str += newKey[i];
 }
 return md5(str + 'yueduqiyuan');
}

function requestLoading(url, params, message) {
 let promise = new Promise((resolve, reject) => {
 wx.showNavigationBarLoading()
 if (message != "") {
  wx.showLoading({

  })
 }
 var timestamp = Date.parse(new Date());
 timestamp = timestamp / 1000;
 params['openid'] = wx.getStorageSync('openid');
 var newParams = this.objKeySort(params);
 newParams['unionid'] = wx.getStorageSync('unionid');
 newParams['antime'] = timestamp;
 newParams['key'] = this.jiamiParams(newParams);
 wx.request({
  url: url,
  data: newParams,
  header: {
  'content-type': 'application/x-www-form-urlencoded'
  },
  method: 'post',
  success: function (res) {
 
  wx.hideNavigationBarLoading()
  if (message != "") {
   wx.hideLoading()
  }
 
  if (res.statusCode == 200) {
   resolve(res.data)
  } else {
   reject(res)
  }
  },
  fail: function (res) {
  wx.hideNavigationBarLoading()
  if (message != "") {
   wx.hideLoading()
  }
  reject('网络出错！')
  }
 })
 
 
 })
 return promise
}
 
module.exports = {
 http: http,
 formatTime: formatTime,
 requestLoading: requestLoading,
 tiaozhuan: tiaozhuan,
 tiaozhuanAd: tiaozhuanAd,
 objKeySort: objKeySort,
 jiamiParams: jiamiParams
}

这个工具函数中用promise封装了微信小程序数据请求的方法：单独拿出来（但不能单独使用哦，因为还需要借助上面的一些工具函数）

function requestLoading(url, params, message) {
 let promise = new Promise((resolve, reject) => {
 wx.showNavigationBarLoading()
 if (message != "") {
  wx.showLoading({
  title: message
  })
 }
 var timestamp = Date.parse(new Date());
 timestamp = timestamp / 1000;
 params['openid'] = wx.getStorageSync('openid');
 var newParams = this.objKeySort(params);
 newParams['unionid'] = wx.getStorageSync('unionid');
 newParams['antime'] = timestamp;
 newParams['key'] = this.jiamiParams(newParams);
 wx.request({
  url: url,
  data: newParams,
  header: {
  'content-type': 'application/x-www-form-urlencoded'
  },
  method: 'post',
  success: function (res) {
 
  wx.hideNavigationBarLoading()
  if (message != "") {
   wx.hideLoading()
  }
 
  if (res.statusCode == 200) {
   resolve(res.data)
  } else {
   reject(res)
  }
  },
  fail: function (res) {
  wx.hideNavigationBarLoading()
  if (message != "") {
   wx.hideLoading()
  }
  reject('网络出错！')
  }
 })
 
 
 })
 return promise
}

使用方法：

util1.requestLoading(url, param, "正在加载数据").then(res => {
  if (res.status == 1) {
  let bannerList = res.data
  that.setData({
   bannerList
  });
  }
 }).catch(()=>{
  wx.showToast({
  title: '加载数据失败',
  })
 })

以上就是本文的全部内容，希望对大家的学习有所帮助，也希望大家多多支持三水点靠木。
