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
'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();

$paramUrl = '';

$this->url = $url;
$this->data = $data;
try{

}catch (Exception $e){

The goal of DVWA is to practice some of the most common web vulnerabilities through a simple and straightforward interface, with varying degrees of difficulty. Please note that this software
mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
