为什么我发写的这个发送邮件网站无法进行发送，具体是接收到了数据但后端没有处理结果，也没有预期的成功或者报错
两组代码如下
index.html
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>信息登记表</title>
<!-- <link rel="stylesheet" href="style07.css" type="text/css"> -->
<style type="text/css">
input {
width: 200px;
height: 18px;
border: 1px solid #d4cdba;
padding: 2px;
}
.btn input {
width: 100px;
height: 30px;
border-radius: 3px;
}
</style>
</head>
<body>
<div class="bg">
<form action="#" method="get" autocomplete="off">
