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。

4.简单的修改和测试

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

plaincopy

/\*\*

\* 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 POSThttp://localhost/post

【2】测试put方法

curl --request PUThttp://localhost/put

【3】测试delete

curl --request DELETEhttp://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。
