下面是基于ThinkPHP V5.0 RC4框架,以restful风格完成的新闻查询(get)、新闻增加(post)、新闻修改(put)、新闻删除(delete)等server接口层。

1、下载ThinkPHP V5.0 RC4版本;

2、配置虚拟域名(非必须,只是为了方便);

Apache\conf\extra\httpd-vhosts.conf

<VirtualHost *:80>    DocumentRoot "D:/webroot/tp5/public"    ServerName www.tp5-restful.com    <Directory "D:/webroot/tp5/public">    DirectoryIndex index.html index.php    AllowOverride All    Order deny,allow    Allow from all    </Directory></VirtualHost>

3、开启伪静态支持.htaccess文件

apache方法:

a)在conf目录下httpd.conf中找到下面这行并去掉#

LoadModule rewrite_module modules/mod_rewrite.so

b)将所有AllowOverride None改成AllowOverride All

public\.htaccess文件内容:

<IfModule mod_rewrite.c> Options +FollowSymlinks -Multiviews RewriteEngine on RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^(.*)$ index.php [L,E=PATH_INFO:$1] </IfModule>

4、创建测试数据

tprestful.sql

-- -- 数据库: `tprestful` -- -- -------------------------------------------------------- -- -- 表的结构 `news` -- CREATE TABLE IF NOT EXISTS `news` (   `id` int(10) unsigned NOT NULL AUTO_INCREMENT,   `title` varchar(255) NOT NULL,   `content` text NOT NULL,   PRIMARY KEY (`id`) ) ENGINE=MyISAM  DEFAULT CHARSET=utf8 COMMENT='新闻表' AUTO_INCREMENT=1; -- -- 转存表中的数据 `news` -- INSERT INTO `news` (`id`, `title`, `content`) VALUES (1, '新闻1', '新闻1内容'), (2, '新闻2', '新闻2内容'), (3, '新闻3', '新闻3内容'), (4, '房价又涨了', '据新华社消息:上海均价环比上涨5%');

5、修改数据库配置文件

application\database.php

<?php return [     // 数据库类型     'type'           => 'mysql',     // 服务器地址     'hostname'       => '127.0.0.1',     // 数据库名     'database'       => 'tprestful',     // 用户名     'username'       => 'root',     // 密码     'password'       => '123456',     // 端口     'hostport'       => '',     // 连接dsn     'dsn'            => '',     // 数据库连接参数     'params'         => [],     // 数据库编码默认采用utf8     'charset'        => 'utf8',     // 数据库表前缀     'prefix'         => '',     // 数据库调试模式     'debug'          => true,     // 数据库部署方式:0 集中式(单一服务器),1 分布式(主从服务器)     'deploy'         => 0,     // 数据库读写是否分离 主从式有效     'rw_separate'    => false,     // 读写分离后 主服务器数量     'master_num'     => 1,     // 指定从服务器序号     'slave_no'       => '',     // 是否严格检查字段是否存在     'fields_strict'  => true,     // 数据集返回类型 array 数组 collection Collection对象     'resultset_type' => 'array',     // 是否自动写入时间戳字段     'auto_timestamp' => false,     // 是否需要进行SQL性能分析     'sql_explain'    => false, ];

6、定义restful风格的路由规则,

application\route.php

<?php use think\Route; Route::get('/',function(){     return 'Hello,world!'; }); Route::get('news/:id','index/News/read');   //查询 Route::post('news','index/News/add');       //新增 Route::put('news/:id','index/News/update'); //修改 Route::delete('news/:id','index/News/delete'); //删除 //Route::any('new/:id','News/read');        // 所有请求都支持的路由规则

7、新建模型

application\index\model\News.php

<?php namespace app\index\model; use think\Model; class News extends Model{     protected $pk = 'id';     //protected static $table = 'news'; }

8、新建控制器

application\index\controller\News.php

<?php namespace app\index\controller; use think\Request; use think\controller\Rest; class News extends Rest{     public function rest(){         switch ($this->method){             case 'get':     //查询                 $this->read($id);                 break;             case 'post':    //新增                 $this->add();                 break;             case 'put':     //修改                 $this->update($id);                 break;             case 'delete':  //删除                 $this->delete($id);                 break;         }     }     public function read($id){         $model = model('News');         //$data = $model::get($id)->getData();         //$model = new NewsModel();         $data=$model->where('id', $id)->find();// 查询单个数据         return json($data);     }     public function add(){         $model = model('News');         $param=Request::instance()->param();//获取当前请求的所有变量(经过过滤)         if($model->save($param)){             return json(["status"=>1]);         }else{             return json(["status"=>0]);         }     }     public function update($id){         $model = model('News');         $param=Request::instance()->param();         if($model->where("id",$id)->update($param)){             return json(["status"=>1]);         }else{             return json(["status"=>0]);         }     }     public function delete($id){         $model = model('News');         $rs=$model::get($id)->delete();         if($rs){             return json(["status"=>1]);         }else{             return json(["status"=>0]);         }     } }

9、测试

a)、访问入口文件,默认在public\index.php

b)、客户端测试restful的get、post、put、delete方法

client\client.php

<?php require_once './ApiClient.php'; $param = array(   'title' => '房价又涨了',   'content' => '据新华社消息:上海均价环比上涨5%' ); $api_url = 'http://www.tp5-restful.com/news/4'; $rest = new restClient($api_url, $param, 'get'); $info = $rest->doRequest(); //$status = $rest->status;//获取curl中的状态信息 $api_url = 'http://www.tp5-restful.com/news'; $rest = new restClient($api_url, $param, 'post'); $info = $rest->doRequest(); $api_url = 'http://www.tp5-restful.com/news/4'; $rest = new restClient($api_url, $param, 'put'); $info = $rest->doRequest(); echo '<pre/>'; print_r($info);exit; $api_url = 'http://www.tp5-restful.com/news/4'; $rest = new restClient($api_url, $param, 'delete'); $info = $rest->doRequest(); ?>

请求工具类

client\ApiClient.php

<?php class restClient{   //请求的token   const token='yangyulong';   //请求url   private $url;   //请求的类型   private $requestType;   //请求的数据   private $data;        //curl实例   private $curl;   public $status;   private $headers = array();   /**    * [__construct 构造方法, 初始化数据]    * @param [type] $url     请求的服务器地址    * @param [type] $requestType 发送请求的方法    * @param [type] $data    发送的数据    * @param integer $url_model  路由请求方式    */   public function __construct($url, $data = array(), $requestType = 'get') {     //url是必须要传的,并且是符合PATHINFO模式的路径     if (!$url) {       return false;     }     $this->requestType = strtolower($requestType);     $paramUrl = '';     // PATHINFO模式     if (!empty($data)) {       foreach ($data as $key => $value) {         $paramUrl.= $key . '=' . $value.'&';       }       $url = $url .'?'. $paramUrl;     }     //初始化类中的数据     $this->url = $url;     $this->data = $data;     try{       if(!$this->curl = curl_init()){         throw new Exception('curl初始化错误:');       };     }catch (Exception $e){       echo '<pre>';       print_r($e->getMessage());       echo '</pre>';     }     curl_setopt($this->curl, CURLOPT_URL, $this->url);     curl_setopt($this->curl, CURLOPT_RETURNTRANSFER, 1);     //curl_setopt($this->curl, CURLOPT_HEADER, 1);   }   /**    * [_post 设置get请求的参数]    * @return [type] [description]    */   public function _get() {   }   /**    * [_post 设置post请求的参数]    * post 新增资源    * @return [type] [description]    */   public function _post() {     curl_setopt($this->curl, CURLOPT_POST, 1);     curl_setopt($this->curl, CURLOPT_POSTFIELDS, $this->data);   }   /**   * [_put 设置put请求]    * put 更新资源    * @return [type] [description]    */   public function _put() {     curl_setopt($this->curl, CURLOPT_CUSTOMREQUEST, 'PUT');   }   /**    * [_delete 删除资源]    * delete 删除资源    * @return [type] [description]    */   public function _delete() {     curl_setopt($this->curl, CURLOPT_CUSTOMREQUEST, 'DELETE');   }   /**    * [doRequest 执行发送请求]    * @return [type] [description]    */   public function doRequest() {     //发送给服务端验证信息     if((null !== self::token) && self::token){       $this->headers = array(         'Client-Token:'.self::token,//此处不能用下划线         'Client-Code:'.$this->setAuthorization()       );     }     //发送头部信息     $this->setHeader();     //发送请求方式     switch ($this->requestType) {       case 'post':         $this->_post();         break;       case 'put':         $this->_put();         break;       case 'delete':         $this->_delete();         break;       default:         curl_setopt($this->curl, CURLOPT_HTTPGET, TRUE);         break;     }     //执行curl请求     $info = curl_exec($this->curl);     //获取curl执行状态信息     $this->status = $this->getInfo();     return $info;   }   /**    * 设置发送的头部信息    */   private function setHeader(){     curl_setopt($this->curl, CURLOPT_HTTPHEADER, $this->headers);   }   /**    * 生成授权码    * @return string 授权码    */   private function setAuthorization(){     $authorization = md5(substr(md5(self::token), 8, 24).self::token);     return $authorization;   }   /**    * 获取curl中的状态信息    */   public function getInfo(){     return curl_getinfo($this->curl);   }   /**    * 关闭curl连接    */   public function __destruct(){     curl_close($this->curl);   } }
