打包h5如何配置域名：
在manifest.json中配置域名

<!DOCTYPE html>
<html lang="zh-CN">
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<title>
<%= htmlWebpackPlugin.options.title %>
</title>
<!-- Open Graph data -->
<!-- <meta property="og:title" content="Title Here" /> -->
<!-- <meta property="og:url" content="http://www.example.com/" /> -->
<!-- <meta property="og:image" content="http://example.com/image.jpg" /> -->
<!-- <meta property="og:description" content="Description Here" /> -->
<script>
var coverSupport = 'CSS' in window && typeof CSS.supports === 'function' && (CSS.supports('top: env(a)') || CSS.supports('top: constant(a)'))
document.write('<meta name="viewport" content="width=device-width, user-scalable=no, initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0' + (coverSupport ? ', viewport-fit=cover' : '') + '" />')
</script>
<!-- 引入eruda -->
<script src="https://cdn.jsdelivr.net/npm/eruda"></script>
<script>eruda.init();</script>
<link rel="stylesheet" href="<%= BASE_URL %>static/index.<%= VUE_APP_INDEX_CSS_HASH %>.css" />
</head>
<body>
<noscript>
