thinkphp5.0极速搭建restful风格接口层实例

作为国内最流行的php框架thinkphp,很快就会发布v5.0正式版了,现在还是rc4版本,但已经很强大了
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:http://www.thinkphp.cn/down/797.html 


2、配置虚拟域名(非必须,只是为了方便),参考http://blog.csdn.net/nuli888/article/details/51830659

Apacheconfextrahttpd-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
applicationdatabase.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 oute.php

<?php
use thinkRoute;
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
applicationindexmodelNews.php

<?php
namespace appindexmodel;
use thinkModel;
class News extends Model{
    protected $pk = 'id';
    //protected static $table = 'news';
}

8、新建控制器
applicationindexcontrollerNews.php

<?php
namespace appindexcontroller;
use thinkRequest;
use thinkcontrollerRest;

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publicindex.php


b)、客户端测试restful的get、post、put、delete方法
clientclient.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
clientApiClient.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();
  /**

   */
  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);

    }
    //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;
