小程序：

<template>
	<view>
		<web-view v-if="webUrl" :src="webUrl"></web-view>
	</view>
</template>

<script>
	export default {
		data() {
			return {
				webUrl: "",
				token: "",
			};
		},
		onLoad() {
			this.token = uni.getStorageSync('userInfo').token
			this.webUrl = "https://dd.ycsmes.com/h5?wx=1&token=" + this.token
			console.log(this.webUrl);
		},
	};
</script>

H5

app.vue中动态引入微信JSSDK，直接在页面中引入会出现wx.miniProgram为undefined (坑了我好久)

		onLaunch(e) {
			var script = document.createElement('script')
			script.src = "https://res.wx.qq.com/open/js/jweixin-1.6.0.js"
			script.type = 'text/javascript';
			document.body.appendChild(script)
		},

在需要进行返回操作的页面

wx.miniProgram.navigateBack()
