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
javascript
!(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 {
var w = JSON.stringify(t)
plus.webview
.getLaunchWebview()
.evalJS(
'UniPlusBridge.subscribeHandler("'
.concat('WEB_INVOKE_APPSERVICE', '",')
.concat(w, ',')
.concat(JSON.stringify(i), ');')
)
}
},
o = {

n = e.url
a('navigateTo', { url: encodeURI(n) })

n = e.delta
a('navigateBack', { delta: parseInt(n) || 1 })
},

a('switchTab', { url: encodeURI(n) })

})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)
javascript
//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 = uniview1.2. 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
javascript
//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
javascript
/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')
})
}
}
