微信小程序获取系统信息的API：

回调参数：Object res

index.wxml示例代码：

<!--index.wxml-->
<view class="container">
  <button bindtap='getInfo'>获取系统信息</button>
  <view wx:if="{{model !=''}}">
    <view>手机型号:{{model}}</view>
    <view>设备像素比:{{pixelRatio}}</view>
    <view>窗口宽度:{{windowWidth}}</view>
    <view>窗口高度:{{windowHeight}}</view>
    <view>微信设置的语言:{{language}}</view>
    <view>微信版本号:{{version}}</view>
    <view>操作系统版本:{{system}}</view>
    <view>客户端平台:{{platform}}</view>
  </view>
</view>

index.js示例代码一：wx.getSystemInfo(Object object)

//index.js
//获取应用实例
const app = getApp()
 
Page({
  data: {
    model: '',
    pixelRatio: '',
    windowWidth: '',
    windowHeight: '',
    language: '',
    version: '',
    system: '',
    platform: ''
  },
  onLoad: function () {
  },
  getInfo: function () {
    var _this = this;
    wx.getSystemInfo({
      success: function (res) {
        _this.setData({
          model: res.model,
          pixelRatio: res.pixelRatio,
          windowWidth: res.windowWidth,
          windowHeight: res.windowHeight,
          language: res.language,
          version: res.version,
          system: res.system,
          platform: res.platform
        })
      },
      fail: function (res) {
 
      },
      complete: function (res) {
 
      }
    })
  }
})

index.js示例代码二：wx.getSystemInfoSync()

//index.js
//获取应用实例
const app = getApp()
 
Page({
  data: {
    model: '',
    pixelRatio: '',
    windowWidth: '',
    windowHeight: '',
    language: '',
    version: '',
    system: '',
    platform: ''
  },
  onLoad: function () {
  },
  getInfo: function () {
    var _this = this;
    try {
      var res = wx.getSystemInfoSync()
      _this.setData({
        model: res.model,
        pixelRatio: res.pixelRatio,
        windowWidth: res.windowWidth,
        windowHeight: res.windowHeight,
        language: res.language,
        version: res.version,
        system: res.system,
        platform: res.platform
      })
