我想用 PHP 和Glue 框架创建一个简单的登录系统。我的代码是这样的：
glue("route")->post("/login", function($params) {
// I'm trying to catch the variable first
echo $params['user'] .'aaand'. $params['pass'];
});
形式是：
<form action="/login" method="POST">
<input type="text" name="user">
<input type="password" name="pass">
</form>
问题是，我怎样才能捕获这两个变量 -user然后pass将其插入 PHP Sessions ？
感谢您的回答和解释！
我会跟你说实话，我和你一样喜欢小脚印。^_^
如果您想了解事物的工作原理并开始构建安全且简单的东西，那没关系。
测试任何来到这个世界的东西并试图打破它，直到你做出一些不可能被破解的东西。;)
首先：在您的 Web 服务器的根目录中创建一个文件夹并将其命名为“ glue ”。
在该文件夹中，使这些文件具有以下内容：
.htaccess
<IfModule mod_rewrite.c>
<IfModule mod_negotiation.c>
Options -MultiViews
</IfModule>
RewriteEngine On
# Redirect Trailing Slashes...
RewriteRule ^(.*)/$ /$1 [L,R=301]
# Handle Front Controller...
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^ index.php [L]
</IfModule>

* glue
*
* Provides an easy way to map URLs to classes. URLs can be literal
* strings or regular expressions.
*
* When the URLs are processed:
* * delimiter (/) are automatically escaped: (\/)
* * The beginning and end are anchored (^ $)
* * An optional end slash is added (/?)
* * The i option is added for case-insensitive searches
*
* Example:
*
* $urls = array(
* '/' => 'index',
* '/page/(\d+)' => 'page'
* );
*
* class page {
* function GET($matches) {
* echo "Your requested page " . $matches[1];

制作完所有这些文件后，您可以通过以下 URL 访问您的微型框架：
http://localhost/glue
User Name: test
Password: test
