thinkphp5.0은 편안한 스타일의 인터페이스 레이어를 빠르게 구축합니다(예제 분석)

下面由thinkphp框架教程栏目给大家介绍thinkphp5.0极速搭建restful风格接口层实例，希望对需要的朋友有所帮助！

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
    &#39;type&#39;           => &#39;mysql&#39;,
    // 服务器地址
    &#39;hostname&#39;       => &#39;127.0.0.1&#39;,
    // 数据库名
    &#39;database&#39;       => &#39;tprestful&#39;,
    // 用户名
    &#39;username&#39;       => &#39;root&#39;,
    // 密码
    &#39;password&#39;       => &#39;123456&#39;,
    // 端口
    &#39;hostport&#39;       => &#39;&#39;,
    // 连接dsn
    &#39;dsn&#39;            => &#39;&#39;,
    // 数据库连接参数
    &#39;params&#39;         => [],
    // 数据库编码默认采用utf8
    &#39;charset&#39;        => &#39;utf8&#39;,
    // 数据库表前缀
    &#39;prefix&#39;         => &#39;&#39;,
    // 数据库调试模式
    &#39;debug&#39;          => 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)
    &#39;deploy&#39;         => 0,
    // 数据库读写是否分离 主从式有效
    &#39;rw_separate&#39;    => false,
    // 读写分离后 主服务器数量
    &#39;master_num&#39;     => 1,
    // 指定从服务器序号
    &#39;slave_no&#39;       => &#39;&#39;,
    // 是否严格检查字段是否存在
    &#39;fields_strict&#39;  => true,
    // 数据集返回类型 array 数组 collection Collection对象
    &#39;resultset_type&#39; => &#39;array&#39;,
    // 是否自动写入时间戳字段
    &#39;auto_timestamp&#39; => false,
    // 是否需要进行SQL性能分析
    &#39;sql_explain&#39;    => false,
];

6、定义restful风格的路由规则，
application\route.php

<?php
use think\Route;
Route::get(&#39;/&#39;,function(){
    return &#39;Hello,world!&#39;;
});
Route::get(&#39;news/:id&#39;,&#39;index/News/read&#39;);	//查询
Route::post(&#39;news&#39;,&#39;index/News/add&#39;); 		//新增
Route::put(&#39;news/:id&#39;,&#39;index/News/update&#39;); //修改
Route::delete(&#39;news/:id&#39;,&#39;index/News/delete&#39;); //删除
//Route::any(&#39;new/:id&#39;,&#39;News/read&#39;); 		// 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 = &#39;id&#39;;
	//protected static $table = &#39;news&#39;;
}

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 &#39;get&#39;: 	//查询
				$this->read($id);
				break;
			case &#39;post&#39;:	//新增
				$this->add();
				break;
			case &#39;put&#39;:		//修改
				$this->update($id);
				break;
			case &#39;delete&#39;:	//删除
				$this->delete($id);
				break;
			
        }
    }
    public function read($id){
		$model = model(&#39;News&#39;);
		//$data = $model::get($id)->getData();
		//$model = new NewsModel();
		$data=$model->where(&#39;id&#39;, $id)->find();// 查询单个数据
		return json($data);
    }
	
	public function add(){
		$model = model(&#39;News&#39;);
		$param=Request::instance()->param();//获取当前请求的所有变量（经过过滤）
		if($model->save($param)){
			return json(["status"=>1]);
		}else{
			return json(["status"=>0]);
		}
    }
	public function update($id){
		$model = model(&#39;News&#39;);
		$param=Request::instance()->param();
		if($model->where("id",$id)->update($param)){
			return json(["status"=>1]);
		}else{
			return json(["status"=>0]);
		}
    }
	public function delete($id){
		
		$model = model(&#39;News&#39;);
		$rs=$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 &#39;./ApiClient.php&#39;;

$param = array(
  &#39;title&#39; => &#39;房价又涨了&#39;,
  &#39;content&#39; => &#39;据新华社消息：上海均价环比上涨5%&#39;
);
$api_url = &#39;http://www.tp5-restful.com/news/4&#39;; 
$rest = new restClient($api_url, $param, &#39;get&#39;);
$info = $rest->doRequest();
//$status = $rest->status;//获取curl中的状态信息


$api_url = &#39;http://www.tp5-restful.com/news&#39;; 
$rest = new restClient($api_url, $param, &#39;post&#39;);
$info = $rest->doRequest();

$api_url = &#39;http://www.tp5-restful.com/news/4&#39;; 
$rest = new restClient($api_url, $param, &#39;put&#39;);
$info = $rest->doRequest();

echo &#39;<pre/>&#39;;
print_r($info);exit;

$api_url = &#39;http://www.tp5-restful.com/news/4&#39;; 
$rest = new restClient($api_url, $param, &#39;delete&#39;);
$info = $rest->doRequest();
?>

请求工具类
client\ApiClient.php

<?php
class restClient
{
  //请求的token
  const token=&#39;yangyulong&#39;;
  
  //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 = &#39;get&#39;) {
      
    //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);
    $paramUrl = &#39;&#39;;
    // PATHINFO模式
    if (!empty($data)) {
      foreach ($data as $key => $value) {
        $paramUrl.= $key . &#39;=&#39; . $value.&#39;&&#39;;
      }
      $url = $url .&#39;?&#39;. $paramUrl;
    }
      
    //初始化类中的数据
    $this->url = $url;
      
    $this->data = $data;
    try{
      if(!$this->curl = curl_init()){
        throw new Exception(&#39;curl初始化错误：&#39;);
      };
    }catch (Exception $e){
      echo &#39;<pre class="brush:php;toolbar:false">&#39;;
      print_r($e->getMessage());
      echo &#39;

'; } 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); } }
