php中怎么實現(xiàn)RESTful風(fēng)格

在php中怎么實現(xiàn)RESTful風(fēng)格？這篇文章運用了實例代碼展示，代碼非常詳細，可供感興趣的小伙伴們參考借鑒，希望對大家有所幫助。

首先定義一個請求數(shù)據(jù)接收類；然后請求類中根據(jù)請求類型，進行訪問不通方法；

 class Request
  {
      // 允許的請求方式
      private static $method_type = array('get', 'post', 'put', 'patch', 'delete');

      // 測試數(shù)據(jù)
      private static $test_class = array(
          1 => array('name'=>'測試一班','count'=>18), 
          2 => array('name'=>'測試二班','count'=>15)
      );

      public static function getRequest()
      {
          // 請求方法
          $method = strtolower($_SERVER['REQUEST_METHOD']);
          if (in_array($method, self::$method_type)) {
              // 調(diào)用請求方法對應(yīng)的方法
              $data_name = $method . "Data";
              return self::$data_name($_REQUEST);
          }
          return false;
      }

      // GET 獲取信息
      private static function getData($request_data)
      {
          $class_id = (int)$request_data['class'];
          if ($class_id > 0) {
              // GET /class/ID: 獲取某個指定班的信息
              return self::$test_class[$class_id];
          }else{ 
              // GET /class: 列出所有班級
              return self::$test_class;
          }
      }

      // POST /class 新建一個班級
      private static function postData($request_data)
      {
          $class_id = (int)$request_data['class'];
          if ($class_id == 0) {
              return false;
          }
          $data = array();
          if (!empty($request_data['name']) && isset($request_data['count'])) {
              $data['name'] = $request_data['name'];
              $data['count'] = $request_data['count'];
              self::$test_class[] = $data;
              return self::$test_class; 
          }else{
              return false;
          }
      }

      // PUT /class/ID 更新某個指定班級的信息(全部信息)
      private static function putData($request_data)
      {
          $class_id = (int)$request_data['class'];
          if ($class_id == 0) {
              return false;
          }

          $data = array();
          if (!empty($request_data['name']) && isset($request_data['count'])) {
              $data['name'] = $request_data['name'];
              $data['count'] = (int)$request_data['count'];
              self::$test_class[$class_id] = $data;
              return self::$test_class;
          }else{
              return false;
          }
      }

      // PATCH /class/ID 更新某個指定班級的信息 (部分信息)
      private static function pacthData($request_data)
      {
          $class_id = (int)$request_data['class'];
          if ($class_id == 0) {
              return false;
          }
          if (!empty($request_data['name'])) {
              self::$test_class[$class_id]['name'] = $request_data['name'];
          }
          if (isset($request_data['count'])) {
              self::$test_class[$class_id]['count'] = $request_data['count'];
          }
          return self::$test_class;
      }

      // DELETE /class/ID 刪除某個班
      private static function deleteData($request_data)
      {
          $class_id = (int)$request_data['class'];
          if ($class_id == 0) {
              return false;
          }
          unset(self::$test_class[$class_id]);
          return self::$test_class;
      }
  }

再定義一個數(shù)據(jù)輸出類，將數(shù)據(jù)輸出的格式進行統(tǒng)一的封裝；最后將方法返回的數(shù)據(jù)進行輸出即可。

  <?php
  /**
  * 包含一個Response類，即輸出類。根據(jù)接收到的Content-Type，將Request類返回的數(shù)組拼接成對應(yīng)的格式，加上header后輸出
  */
  class Response
  {
      const HTTP_VERSION = "HTTP/1.1";
  
      public function sendResponse($data)
      {
          // 獲取數(shù)據(jù)
          if ($data) {
              $code = 200;
              $message = "OK";
          }else{
              $code = 404;
              $data = array('error' => "Not Found");
              $message = "Not Found";
          }
  
          header(self::HTTP_VERSION . " $code $message");
          $content_type = isset($_SERVER['CONTENT_TYPE']) ? $_SERVER['CONTENT_TYPE'] : $_SERVER['HTTP_ACCEPT'];
          if (strpos($content_type, 'application/json') !== false) {
              header("Content-Type: application/json");
              echo self::encodeJson($data);
          }elseif (strpos($content_type, 'application/xml') !== false) {
              header("Content-Type: application/xml");
              echo self::encodeXml($data);
          }else{
              header("Content-Type: text/html");
              echo self::encodeHtml($data);
          }
      }
  
      // json 格式
      private static function encodeJson($responseData)
      {
          return json_encode($responseData);
      }
  
      // xml 格式
      private static function encodeXml($responseData)
      {
          $xml = new SimpleXMLElement('<?xml version="1.0"?><rest></rest>');
          foreach ($responseData as $key => $value) {
              if (is_array($value)) {
                  foreach ($value as $k => $v) {
                      $xml->addChild($k,$v);
                  }
              }else{
                  $xml->addChild($key,$value);
              }
          }
          return $xml->asXML();
      }
  
      // html 格式
      private static function encodeHtml($responseData)
      {
          $html = "<table border='1'>";
          foreach ($responseData as $key => $value) {
              $html .= "<tr>";
              if (is_array($value)) {
                  foreach ($value as $k => $v) {
                      $html .= "<td>$k</td><td>$v</td>";
                  }
              }else{
                  $html .= "<td>$key</td><td>$value</td>";
              }
              $html .= "</tr>";
          }
          $html .="</table>";
          return $html;
      }
  }
  ?>
