我有一个React-Flask项目，该项目需要为一些后端端点呈现静态内容。这是我的简化结构：
client/
src/
components/
Menus.jsx
public/
bg.png
index.html
manifest.json
web/
project/
api/
routes/
static/
css/
bootstrap.css
mug.css
templates/
menu.html
partials/
head.html
反应前端
因此，如果我尝试渲染静态的menu.html页面，我将通过ajax GET获取并使用Jinja2直接从Flask注入我的dangerouslySetInnerHTML模板，就像这样：
Menus.jsx
render(){
var menu_html = this.state.menu_template;
var menu_template = { __html: menu_html };
return (
<div id="parent">
<h1 className="title is-1"><font color="#C86428">Menu</font></h1>
<hr/><br/>
<div dangerouslySetInnerHTML={menu_template}/>
</div>
);
}
在index.html，我将一些常规css与bulma链接：
Index.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8" />
<link rel="shortcut icon" href="%PUBLIC_URL%/favicon.ico" />
<meta name="viewport"
content="width=device-width, initial-scale=1, shrink-to-fit=no"
/>
<meta name="theme-color" content="#000000" />
<link rel="manifest" href="%PUBLIC_URL%/manifest.json" />
<link href="//cdnjs.cloudflare.com/ajax/libs/bulma/0.7.2/css/bulma.min.css"rel="stylesheet">
<title>App</title>
</head>
<body>
<style>
body {
background-color: #C86428;
background-image: url("bg.png");
background-position: 0 5;
opacity: 1.0;
height: 120vh;
}
</style>
<div id="root" />
</body>
</html>
烧瓶后端
在这里，我尝试在css处链接我的静态head.html：
head.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<link type="text/css" href="{{url_for('static', filename='css/bootstrap.css')}}">
<link type="text/css" href="{{url_for('static', filename='css/mug.css')}}">
</head>
<body>
然后在插入的模板顶部通过css插入partials/head.html，如下所示：
menus.html
{% include 'partials/head.html' %}
<section id="woz-content" >
<body>
<div className="container">
<ul style="list-style:none" >
<li><a href="{{ url_for('loading',name=items[0])}}";><font color="#C86428">{{ item[0] }}</font></a>
<form action="{{ url_for('menus.handle_menu', user_id=user_id) }}" method="post">
<input type="radio" name="additive" value="additive1" style="font-size:10px"> <label style="font-size: 11px;"><font color="#C86428">Additive 1</font></label>
<input type="submit" value="add" >
</form></li>
(...)
loading.html
{% include 'partials/head.html' %}
<div class="cup">
<div class="coffee"></div>
</div>
<div class="smoke" />
<p class="txt">Brewing your coffee...<br><small></small></p>
<script>
window.location.replace('/item/{{name}}');
</script>

问题：
正在渲染模板，但是没有样式，也就是说，css/mug.css没有被应用在最前端。我在这里想念什么？
答案 0 :(得分：0)
您需要在index.html中指定下面的URL，而不是head.html
<link type="text/css" href="{{url_for('static', filename='css/bootstrap.css')}}">
<link type="text/css" href="{{url_for('static', filename='css/mug.css')}}">
