PHP架構slim的安裝使用方法

最簡單粗暴和直接的方法——到github下載zip檔案，slim github【連結】。解壓之後把【1】Slim檔案夾，【2】.htaccess檔案和【3】index.php檔案複製到www目錄中。若看到以下網頁說明slim安裝成功。

4.簡單的修改和測試

Slim提供完善的REST架構，支援GET、POST、PUT和Delete等方法，可以把index.php修改的更簡單一些。可從以下代碼中可以熟悉Slim的基本架構和使用方法。

[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();        此時再開啟瀏覽器輸入localhost將只能看到以下內容，其實瀏覽器使用get方法，在slim的Get路由中輸出了Hello Slim。  $app->post(      '/post',      function () {          echo 'This is a POST route';      }  );

在slim中， '/post'為相對路徑，該路徑可支援變數。 function ()為後續的處理函數。其他HTTP方法也類似。

其他類型的測試方法可藉助cURL工具

【1】測試post

curl --request POST http://localhost/post

【2】測試put方法

curl --request PUT http://localhost/put

【3】測試delete

curl --request DELETE http://localhost/delete

【Firefox瀏覽器】

如果你不喜歡使用curl工具，也可以選擇Firefox瀏覽器中的HTTPRequest工具，那麼命令操作就成了愉快的GUI操作了。
