环境搭建
composer config -g repo.packagist composer https://mirrors.aliyun.com/composer/
composer create-project topthink/think tp
php think run
框架基础规则
继承引入
use app\BaseController;
class coleak extends BaseController
use进行引入,然后继承基础的方法
单应用模式
入口文件(index.php)可以省略
http://localhost:8000/coleak/test
http://localhost:8000/index.php/coleak/test
多应用模式
composer require topthink/think-multi-app
在app里新建文件夹,并将相应的控制器(controller)放到新建的文件夹下
遵守类名和文件名一致,空间名和文件夹名一致
namespace app\cc\controller;
http://localhost:8000/cc/coleak/test
自定义路由
http://localhost:8000/coleak/hello/a
调试器
重命名为 .env
public function c()
{
$arr=['id'=>1,"name"=>"coleak"];
$name='coleak';
// return "666".'21a1';
// return json($arr);
// dump($arr);
// dump($name);
// halt终止程序并输出dunp
// halt($arr);
// halt($name);
//
// trace调试器中输出
trace($arr);
trace($name);
// dump($ar);
}
空控制器
在controller下面定义个Error.php
<?php
namespace app\cc\controller;
class Error{
public function __call($name, $arguments)
{
// TODO: Implement __call() method.
return "Error Requests!";
}
}
视图
模板引擎安装
composer require topthink/think-view
看下composer.json
"require": {
"php": ">=7.2.5",
"topthink/framework": "^6.1.0",
"topthink/think-orm": "^2.0",
"topthink/think-filesystem": "^1.0",
"topthink/think-multi-app": "^1.0",
"topthink/think-view": "^1.0"
},
渲染模板
public function t()
{
return view(1);
}
//如果html文件名和方法名一致,即为t.html。则无需参数
public function t()
{
return view();
}
facade代理
use think\facade\View;
public function t()
{
// return view();
return View::fetch();
}
//或者直接使用(不推荐)
return \think\facade\View::fetch();
当方法使用驼峰命名法是,如testColeak,则对应的html文件应该为test_coleak
变量传递
view.php
'tpl_begin' => '{',
// 模板引擎普通标签结束标记
'tpl_end' => '}',
// 标签库标签开始标记
'taglib_begin' => '{',
// 标签库标签结束标记
'taglib_end' => '}',
语法
public function testColeak(){
View::assign("name","coleak");
View::assign("age",19);
return View::fetch();
}
{$name}
{$age}
查看编译后的文件
在runtime/cc/temp
发现进行了一个htmlentities处理,不让html标签解析,进行原样显示
让其解析则加一个|raw
{$name}
<br>
{$name|raw}
View::assign("name","<h1>coleak</h1>");
<?php echo htmlentities($name); ?>
<br>
<?php echo $name; ?>
默认值
{$a|default="coleak"}
数组按键取值
$arr=["name"=>"coleak","age"=>19];
View::assign("arr",$arr);
{$arr["name"]}-{$arr.age}
md5加密
{$arr["name"]|md5}-{:md5($arr.name)}
请求
request信息
//http://127.0.0.1:8000/cc/c/test
public function test()
{
// dump(Request::method());
dump($this->request->method());
dump($this->request->ip());
dump($this->request->host());
dump($this->request->scheme());
dump($this->request->url());
dump($this->request->root());
dump($this->request->baseUrl());
}
^ "GET" ^ "127.0.0.1" ^ "127.0.0.1:8000" ^ "http" ^ "/cc/c/test" ^ "/cc" ^ "/cc/c/test"
参数接收
//http://127.0.0.1:8000/cc/c/server/b/2?a=45
public function server()
{
dump($this->request->get());
//pathinfo传参
// /参数名1/参数值1/参数名2/参数值2...
dump($this->request->route());
//通用的
dump($this->request->param());
}
^ array:1 [▼
“a” => “45”
]
^ array:1 [▼
“b” => “2”
]
^ array:2 [▼
“a” => “45”
“b” => “2”
]
生成URL
public function url()
{
echo Route::buildUrl();
echo "<br>";
echo Route::buildUrl("coleak/testColeak",["name"=>"coleak","age"=>19]);
echo "<br>";
echo Route::buildUrl("coleak/testColeak",["name"=>"coleak","age"=>19])
->domain("www.baidu.com")
->suffix("phtml");
echo "<br>";
echo url("coleak/testColeak",["name"=>"coleak","age"=>19]);
}
/cc/C/url.html /cc/coleak/testColeak.html?name=coleak&age=19 http://www.baidu.com/cc/coleak/testColeak.phtml?name=coleak&age=19 /cc/coleak/testColeak.html?name=coleak&age=19

'age.number'=>"年龄不为数字",
'age.between'=>"年龄不符合范围",
];
}
public function add(){
$arr1=["name"=>"coleakxiao","age"=>19];
$arr2=["name"=>"小1","age"=>19];
$arr3=["name"=>"小","age"=>11];
$arr4=["name"=>"小小小","age"=>22];
$stu=new Student();
// if(!$stu->check($arr1))
// {
// echo $stu->getError().PHP_EOL;
// }
// if(!$stu->check($arr4))
// {
// echo $stu->getError().PHP_EOL;
// }
// echo "successed".PHP_EOL;
// validate(Student::class)->check($arr4);
// validate(Student::class)->check($arr1);//验证失败会抛出异常
//匿名函数形式验证方式
validate(
['name'=>"require|chs|length:2,15"],
['name.require'=>"姓名为空", 'name.chs'=>"姓名不为汉字", 'name.length'=>"姓名长度错误",]
)->check($arr4);
//scene定义场景验证,function自定义接口验证
try {
// echo $aaa;
validate(Student::class)->check($arr4);
validate(Student::class)->check($arr1);
}catch(ValidateException $e)
{
echo $e->getMessage();
}
catch (\Exception $e)//两次捕获不同的异常,验证异常放在普通的异常捕获前面
{
echo $e->getMessage();
}
}
表单令牌
public function form(){
if($this->request->isPost() and $this->request->checkToken("__token__"))
{
// $r1=$this->request->checkToken("__token__");
// dump($r1);
//或者直接在验证器里面设置 'name'=>"require|chs|length:2,15|token:__token__"
dump($this->request->param());
}
else {
return View::fetch();
}
}
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<form action="" method="post">

中间件
php think make:middleware Check middleware.php中修改 \app\middleware\Check::class public function handle($request, \Closure $next) { dump(111); // if ($request->param()) return $next($request); }
杂项
session
开启session中间件 \think\middleware\SessionInit::class文章来源:https://www.toymoban.com/news/detail-426655.html
class coleak extends BaseController
{
public function ss1(){
Session::set("name","coleak");
$arr=["name"=>"coleak1","age"=>19,"sex"=>"男"];
Session::set("arr",$arr);
}
public function ss2()
{
dump(Session::get("arr"));
Session::delete("name");
dump(Session::has("name"));
dump(Session::all());
Session::clear();
dump(Session::all());
}
在config/session.php配置session相关的属性文章来源地址https://www.toymoban.com/news/detail-426655.html
Cookie
public function ss3()
{
Cookie::set("name","ayuexiao",3600);
dump(Cookie::get("name"));
Cookie::delete("name");
}
