home.html:

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <title>个人信息页面</title>
</head>
<body>
<p>个人信息页面</p> 
</body>
</html>

只有返回一串字符串

login.html:

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <title>登录页面</title>
</head>
<body> 
<p>登录页面</p> 
<form action="/login/" method="post">
  {% csrf_token %}
  <p>
    账号:
    <input type="text" name="user">
  </p>
  <p>
    密码:
    <input type="text" name="pwd">
  </p>
  <p>
    <input type="submit" value="登录">
  </p>
</form>
</body>
</html>

要考虑加上 csrf_token,不然会 403
