获取浏览器数据

1.从其他项目跳转到本项目，在本项目下获取项目跳转来源url

document.referrer

但是也有不可使用的情况

1. 直接在浏览器地址栏中输入地址；
2. 使用location.reload()刷新（location.href或者location.replace()刷新有信息）；
3. 在微信对话框中，点击链接进入微信自身的浏览器；
4. 扫码进入QQ或者微信的浏览器；
5. 直接新窗口打开一个页面； 2017.8.3更新 新版本Chrome测试，新窗口页面依然有document.referrer
6. 从https的网站直接进入一个http协议的网站（Chrome下亲测）；
7. a标签设置rel="noreferrer"（兼容IE7+）；
8. meta标签来控制不让浏览器发送referer；

2.获取访问IP、地区、浏览器以及电脑操作系统

• 在index.html中添加搜狐接口的引用<script src="http://pv.sohu.com/cityjson?ie=utf-8"></script>
• 在js中获取本地id 


• sessionStorage.setItem('ip', returnCitySN["cip"])
      sessionStorage.setItem('area', returnCitySN["cname"])

3.新建js文件systemTool.js

// get brower
export function GetCurrentBrowser () {
  let ua = navigator.userAgent.toLocaleLowerCase()
  let browserType = null
  if (ua.match(/msie/) != null || ua.match(/trident/) != null) {
    browserType = 'IE'
  } else if (ua.match(/firefox/) != null) {
    browserType = 'firefox'
  } else if (ua.match(/ucbrowser/) != null) {
    browserType = 'UC'
  } else if (ua.match(/opera/) != null || ua.match(/opr/) != null) {
    browserType = 'opera'
  } else if (ua.match(/bidubrowser/) != null) {
    browserType = 'baidu'
  } else if (ua.match(/metasr/) != null) {
    browserType = 'sougou'
  } else if (ua.match(/tencenttraveler/) != null || ua.match(/qqbrowse/) != null) {
    browserType = 'QQ'
  } else if (ua.match(/maxthon/) != null) {
    browserType = 'maxthon'
  } else if (ua.match(/chrome/) != null) {
    var is360 = _mime('type', 'application/vnd.chromium.remoting-viewer')
    if (is360) {
      browserType = '360'
    } else {
      browserType = 'chrome'
    }
  } else if (ua.match(/safari/) != null) {
    browserType = 'Safari'
  } else {
    browserType = 'others'
  }
  return browserType
}

function _mime (option, value) {
  var mimeTypes = navigator.mimeTypes
  for (var mt in mimeTypes) {
    if (mimeTypes[mt][option] === value) {
      return true
    }
  }
  return false
}

// get os
export function GetOs () {
  let sUserAgent = navigator.userAgent.toLocaleLowerCase()
  let isWin = (navigator.platform === 'win32') || (navigator.platform === 'windows')
  let isMac = (navigator.platform === 'mac68k') || (navigator.platform === 'macppc') || (navigator.platform === 'macintosh') || (navigator.platform === 'macintel')
  if (isMac) return 'Mac'
  var isUnix = (navigator.platform === 'x11') && !isWin && !isMac
  if (isUnix) return 'Unix'
  var isLinux = (String(navigator.platform).indexOf('linux') > -1)
  if (isLinux) return 'Linux'
  if (isWin) {
    var isWin2K = sUserAgent.indexOf('windows nt 5.0') > -1 || sUserAgent.indexOf('windows 2000') > -1
    if (isWin2K) return 'Win2000'
    var isWinXP = sUserAgent.indexOf('windows nt 5.1') > -1 || sUserAgent.indexOf('windows xp') > -1
    if (isWinXP) return 'WinXP'
    var isWin2003 = sUserAgent.indexOf('windows nt 5.2') > -1 || sUserAgent.indexOf('windows 2003') > -1
    if (isWin2003) return 'Win2003'
    var isWinVista = sUserAgent.indexOf('windows nt 6.0') > -1 || sUserAgent.indexOf('windows vista') > -1
    if (isWinVista) return 'WinVista'
    var isWin7 = sUserAgent.indexOf('windows nt 6.1') > -1 || sUserAgent.indexOf('windows 7') > -1
    if (isWin7) return 'Win7'
  }
  if (sUserAgent.indexOf('android') > -1) return 'Android'
  if (sUserAgent.indexOf('iphone') > -1) return 'iPhone'
  if (sUserAgent.indexOf('symbianos') > -1) return 'SymbianOS'
  if (sUserAgent.indexOf('windows phone') > -1) return 'Windows Phone'
  if (sUserAgent.indexOf('ipad') > -1) return 'iPad'
  if (sUserAgent.indexOf('ipod') > -1) return 'iPod'
  return 'others'
}

// getAddress
// {/*<script src="http://pv.sohu.com/cityjson?ie=utf-8"></script>*/}
// {/*export function GetAddress () {*/}
//   {/*return returnCitySN*/}
// {/*}*/}

　　

• 使用。在你需要用的vue组件中引用上一步js文件
• import * as sysTool from '../assets/js/systemTool'
• 在data里

• data () {
    return {
        ip: '1.1.1.1',
        area: '北京市',
        brower: 'chrome',
        os: 'windows7'
    }
  }

  在具体函数中使用

•  this.ip = sessionStorage.getItem('ip')
            this.area = sessionStorage.getItem('area')
            this.brower = sysTool.GetCurrentBrowser()
            this.os = sysTool.GetOs()
            console.log('ip，地区，浏览器，操作系统，：',  this.ip, this.area,this.brower, this.os)
