前言：采用v-html方法处理

1.处理前

<html><head><meta http‐equiv="Content‐Type" content="text/html; charset=UTF-8"></head><body><form ↵<input type="submit" value="立刻提交" style="display:none" >↵</form>↵<script>document.forms[0].submit();</script></body></html>

2.处理后

<form <input type="submit" value="立刻提交" style="display:none" >↵</form>↵<script>document.forms[0].submit();<\/script>

3.跳转页面方法

//传参
uni.setStorageSync("ICBC_GW_V3_HTML",res.result.payUrl)
//跳转 
uni.navigateTo({url:"/subpages/cashier/webView"})

4.被跳转页面

<template><view v-html="htmlContent"></view>
</template><script>
export default {data() {return {htmlContent:""}},onLoad(e) {console.log(e)//获取参数const html=uni.getStorageSync("ICBC_GW_V3_HTML")console.log(html)this.htmlContent=this.processHtml(html)console.log(this.htmlContent)},mounted() {document.forms[0].submit();},methods: {//仅保留body里面的内容processHtml(html) {// 1. 提取标签内的内容const bodyMatch = html.match(/<body>([\s\S]*)<\/body>/i);if (!bodyMatch) return '';let bodyContent = bodyMatch[1];// 2. 转义标签，防止script中断bodyContent = bodyContent.replace(/<\/script>/g, '<\\/script>');return bodyContent;}}
};
</script><style></style>
