最简单粗暴和直接的方法——到github下载zip文件，slim github【链接】。解压之后把【1】Slim文件夹，【2】.htaccess文件和【3】index.php文件复制到www目录中。若看到以下网页说明slim安装成功。

Slim提供完善的REST框架，支持GET、POST、PUT和Delete等方法，可以把index.php修改的更简单一些。可从以下代码中可以熟悉Slim的基本框架和使用方法。
[php] view plain copy
<?php
/**
* Step 1: Require the Slim Framework
*
* If you are not using Composer, you need to require the
* Slim Framework and register its PSR-0 autoloader.
*
* If you are using Composer, you can skip this step.
*/
require 'Slim/Slim.php';
\Slim\Slim::registerAutoloader();
/**
* Step 2: Instantiate a Slim application
*
* This example instantiates a Slim application using
* its default settings. However, you will usually configure
* your Slim application now by passing an associative array
* of setting names and values into the application constructor.
*/
$app = new \Slim\Slim();
/**
* Step 3: Define the Slim application routes
*
* Here we define several Slim application routes that respond
* to appropriate HTTP request methods. In this example, the second
* argument for `Slim::get`, `Slim::post`, `Slim::put`, `Slim::patch`, and `Slim::delete`
* is an anonymous function.
*/
// GET route
$app->get(
'/',
function () {
echo 'Hello Slim';
}
);
// POST route
$app->post(
'/post',
function () {
echo 'This is a POST route';
}
);
// PUT route
$app->put(
'/put',
function () {
echo 'This is a PUT route';
}
);
// PATCH route
$app->patch('/patch', function () {
echo 'This is a PATCH route';
});
// DELETE route
$app->delete(
'/delete',
function () {
echo 'This is a DELETE route';
}
);
/**
* Step 4: Run the Slim application
*
* This method should be called last. This executes the Slim application
* and returns the HTTP response to the HTTP client.
*/
$app->run();
此时再打开浏览器输入localhost将只能看到以下内容，其实浏览器使用get方法，在slim的Get路由中输出了Hello Slim。
$app->post(
'/post',
function () {
echo 'This is a POST route';
}
);在slim中， '/post'为相对路径，该路径可支持变量。 function ()为后续的处理函数。其他HTTP方法也类似。

其他类型的测试方法可借助cURL工具
【1】测试post
curl --request POST http://localhost/post
【2】测试put方法
curl --request PUT http://localhost/put
【3】测试delete
curl --request DELETE http://localhost/delete
【火狐浏览器】
如果你不喜欢使用curl工具，也可以选择火狐浏览器中的HTTPRequest工具，那么命令操作就成了愉快的GUI操作了。
