404页面是为了让网站或者应用更加友好二存在的，本文是针对不同环境制止404页面的一些方法。
1.html页面制止404页面
html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>404 - Page Not Found</title>
<style>
body {
font - family: Arial, sans - serif;
background - color: #f4f4f4;
text - align: center;
}
h1 {
color: #333;
}
p {
color: #666;
}
a {
color: #007BFF;
text --decoration: none;
}
</style>
</head>
<body>
<h1>404 - Oops! Page Not Found</h1>
<p>The page you are looking for might have been removed, had its name changed, or is temporarily unavailable.</p >
<p>You can return to the homepage or try using the search bar to find what you need.</p >
</body>
</html>
2.php环境制止404页面
如果你使用的是服务器端脚本语言（如PHP），以下是一个PHP版本的示例（这里主要是简单处理并展示一个自定义的404页面，需结合服务器配置才能真正发挥404页面功能）：
<?php
// 设置HTTP状态码为404
http_response_code(404);
?>
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>404 - Page Not Found in PHP</title>
<style>
body {
font - family: Arial, sans - serif;
background - color: #f4f4f4;
text - align: center;
}
h1 {
color: #333;
}
p {
color: #666;
}
a {
color: #007BFF;
text - decoration: none;
}
</style>
</head>
<body>
<h1>404 - Uh - oh! Page Not Found</h1>
<p>The page you were looking for was not found on our server. It could be that it has been removed or relocated.</p >
<p>Click here to go back to the home page.</p >
</body>
</html>
3.ASP.NET环境制止404页面
如果你使用的是ASP.NET，以下是一个简单的C#代码示例（同样需结合服务器配置）：
<%@ Page Language = "C#" AutoEventWireup = "true" CodeBehind = "404.aspx.cs" Inherits = "YourNamespace.404" %>
<!DOCTYPE html>
<html xmlns = "http://www.w3.org/2013/xhtml">
<head>
<meta http-equiv = "Content - Type" content = "text/html; charset=utf - 8" />
<title>404 - Page Not Found in ASP.NET</title>
<style>
body {
font - family: Arial, sans - serif;
background - color: #f4f4f4;
text - align: center;
}
h1 {
color: #333;
}
p {
color: #666;
}
a {
color: #007BFF;
text - decoration: none;
}
</style>
</head>
<body>
<h1>404 - Page Not Found in ASP.NET</h1>
<p>The page you are looking for cannot be located. Please check the URL or use the search feature.</p >
<p>You can return to the home page.</p >
</body>
</html>
404页面的制止在不同的服务器环境中对于404页面的部署方式有所不同。在使用过程中，在以上的方法中我们可以根据实际需求修改页面内容中的文字、颜色、样式以及指向链接等相关元素，以达到最理想的效果。
