1. uniapp 用web-view 嵌套uniapp

  uniapp开发的APP要嵌套uniapp开发的h5,并且APP后面还要打包H5,这就涉及app和h5之间的通信,h5和h5之间的通信。

1.1. 准备工作

  无论是app和h5通信还是 h5和h5之间的通信都是需要引入web-view的sdk文件 我下载的是1.5.2版本,代码如下

!(function (e, n) {
  'object' == typeof exports && 'undefined' != typeof module
    ? (module.exports = n())
    : 'function' == typeof define && define.amd
    ? define(n)
    : ((e = e || self).uni = n())
})(this, function () {
  'use strict'
  try {
    var e = {}
    Object.defineProperty(e, 'passive', {
      get: function () {
        !0
      },
    }),
      window.addEventListener('test-passive', null, e)
  } catch (e) {}
  var n = Object.prototype.hasOwnProperty
  function t(e, t) {
    return n.call(e, t)
  }
  var i = [],
    a = function (e, n) {
      var t = { options: { timestamp: +new Date() }, name: e, arg: n }
      if (window.__dcloud_weex_postMessage || window.__dcloud_weex_) {
        if ('postMessage' === e) {
          var a = { data: [n] }
          return window.__dcloud_weex_postMessage
            ? window.__dcloud_weex_postMessage(a)
            : window.__dcloud_weex_.postMessage(JSON.stringify(a))
        }
        var o = {
          type: 'WEB_INVOKE_APPSERVICE',
          args: { data: t, webviewIds: i },
        }
        window.__dcloud_weex_postMessage
          ? window.__dcloud_weex_postMessageToService(o)
          : window.__dcloud_weex_.postMessageToService(JSON.stringify(o))
      }
      if (!window.plus)
        return window.parent.postMessage(
          { type: 'WEB_INVOKE_APPSERVICE', data: t, pageId: '' },
          '*'
        )
      if (0 === i.length) {
        var r = plus.webview.currentWebview()
        if (!r) throw new Error('plus.webview.currentWebview() is undefined')
        var d = r.parent(),
          s = ''
        ;(s = d ? d.id : r.id), i.push(s)
      }
      if (plus.webview.getWebviewById('__uniapp__service'))
        plus.webview.postMessageToUniNView(
          { type: 'WEB_INVOKE_APPSERVICE', args: { data: t, webviewIds: i } },
          '__uniapp__service'
        )
      else {

})

  下载到本地,嵌入的h5页面引入 也可以直接全局引入在main.js里面(本人是main.js里导入的)

//main.js引入
import uniview from './pages/login/uni.webview.1.5.2'
//挂载到全局实例上面
// web-view SDK
Vue.prototype.uniview = uniview

1.2. app和h5通信(真机调试 ||打包后)

  无论是app和h5通信还是 h5和h5之间的通信都是需要引入web-view的sdk文件 我下载的是1.5.2版本,代码如下

//app页面向h5页面传参采用的是路径传参
 <view class="content">
    <web-view :src="http://192.168.1.149:8082?token=1231" @message="getMessage" />
 </view>
 
//h5页面接收
onLoad(options){
 console.log('第一次登录@', options.token)
}
 
 
//h5页面向app页面传参
 this.uniview.webView.postMessage({
        data: {
          type: 'pay_copy',
          message: '传过去的参数',
        },
    }) 
//app页面接收  绑定@message事件   //只会在真机调试时生效!!!!!!!!!!!!!!!!
<view class="content">
    <web-view :src="http://192.168.1.149:8082?token=1231" @message="getMessage" />
 </view>
 
 getMessage(value) {
 console.log(value, '传过来的参数')
}

1.3. h5和h5之间通信

/内嵌的h5页面  (和h5传app一样不需要改)
 this.uniview.webView.postMessage({
        data: {
          type: 'pay_copy',
          message: this.detailList,
        },
      })
//父级h5(接收用window的方法接收)
onLoad() {
if (window) {
  window.addEventListener('message', (e) => {
     //可以通过e里面的参数 orgin判断是否是要嵌入的h5  (判断一下来源安全一些)
   console.log(e, 'h5传过来的')
})
}
}
