输出config文件-app.php内容

halt(thinkfacadeConfig::get('app'));

抛出异常 throw new thinkException('异常消息', 10006);
abort(404, '异常消息');//abort助手函数快速抛出一个HTTP异常

>php think make:validate index@User  //生成validate，index模块下叫User
>php think make:controller index@test/Blog --plain  //生成“空”控制器，index/test，叫Blog
>php think make:validate common@api/UserLogValidate //生成验证器，common下api文件，叫UserLogValidate
request()->post(); //助手函数

<?php
declare (strict_types = 1);namespace appadmincontroller;use thinkcaptchafacadeCaptcha;class yanzhengma
{/*** tp6扩展验证码输出模板* 在应用的config目录下面的captcha.php进行配置* 文档：*/public function index(){return Captcha::create();}public function yanIsTrue(){//助手函数不需use$value = request()->post();
//        halt($value);// 检测输入的验证码是否正确，$value为用户输入的验证码字符串if( !captcha_check($value )){// 验证失败}}
}

		try {abort(404, '异常消息');} catch (Exception $e) {echo 222;}

public function index(){$param = request()->post();try {validate(UserLogValidata::class)->scene('index')->check($param);} catch (ValidateException $e) {return json($e->getError());}Db::startTrans();try {$a = FaWork::update(['username' => 'thinkphp', 'id' => 5]);Db::commit();} catch (Exception $e) {Db::rollback();echo 222;}

**

一：中间件

固定代码：

public function handle($request, Closure $next){return $next($request);}

**
1，全局中间件

在app/middleware.php定义的中间件

return [// Session初始化thinkmiddlewareSessionInit::class
];

2，应用中间件

<?php
declare (strict_types = 1);namespace appadminmiddleware;use thinkfacadeCache;
use thinkresponseJson;
use appadminmodelFaWork;class Auth
{/*** 处理请求** @param thinkRequest $request* @param Closure       $next* @return Response*///app/middleware.php应用注册public function handle($request, Closure $next){//判断用户身份，以下是中间件里面代码，每行打印输出可查看结果
//        $used = $request->param('used');
//        //判断used存不存在，可以使用全局缓存进行验证，
//        $a = Cache::get($used);
//        if (!$a){
//             abort(404, '身份验证失败');
//        }
//        用sql也可以，需要use，model
//        $sql = fawork::select()->toArray();
//        var_dump($sql);
//        die();return $next($request);}
}

3.控制器中间件

class Index extends FrontController
{protected $middleware = [   appadminmiddlewareCheckAdmin::class];public function index(){echo 'test';}
}

二：validate验证器

<?phpnamespace appadmincontroller;use thinkfacadeRequest;
use appadminmodelfawork;
use appcommonvalidateadminUserLogValidata;
use thinkexceptionValidateException;class Fastworker
{/*** 验证器--控制器代码*/public function index(){$param = request()->post();try {validate(UserLogValidata::class)->scene('index')->check($param);} catch (ValidateException $e) {return json($e->getError());}}

<?php
declare (strict_types = 1);namespace appcommonvalidateadmin;use thinkValidate;class UserLogValidata extends Validate
{//验证器代码protected $rule =   ['id'    => ['require','number'],'name'  => ['require','max'=>'25'],'age'   => ['require','number','between'=>'1,120'],'phone' => ['require','number'],'email' => 'email',];protected $message  =   [&#quire' => ['code'=>100,'msg'=>'名称必须'],'name.max'     => '名称最多不能超过25个字符','age.number'   => '年龄必须是数字','age.between'  => '年龄只能在1-120之间','email'        => '邮箱格式错误',&#quire'   => ['cede'=>100,'msg'=>'id没传值'],];protected $scene = ['index'  =>  ['name','age'],'delete' =>  ['id','phone'],];
}

三：路由

route/app.php ----这里是全局路由
你的模块名/route/app.php ------模块下的路由

<?phpuse thinkfacadeRoute;//路由:st/think
Route::get('think', function () {return 'hello,ThinkPHP6!';
});这里是route/app.php全局路由方式
Route::rule('a','app\admin\controllerFastworker@index','GET|POST');

访问方式：域名/a

这里是-你的模块名/route/app.php   ------模块下的路由
访问方式：域名/模块名/a
Route::rule('a','Fastworker/index','GET|POST');

用于admin/controller/fastadmin控制器里面的方法，后续维护$lu
$lu = ['a'=>'index','b'=>'list'
];
foreach ($lu as $key=>$value){Route::rule($key,'app\admin\controllerFastworker@'.$value,'GET|POST');
}

四：数据库

输出当前sql

DB::name("cart_info")->where('cart_id', 24)->fetchSql(true)->find();

五：模型

关联模型:一对一关联

方式一：预载入-------model里面

<?php
declare (strict_types = 1);namespace appmodel;use thinkModel;class Collection extends Model
{protected $table = 'wy_collection';protected $pk = 'id';//关联分类表public function category(){//hasone 参数：Category表名，'id'Category表的主键，'cate_id'Collection 表的外键return $this->hasOne(Category::class,'id','cate_id')->bind(['cre_name'=>'name']);}
}

controller：

with方法可以传入数组，表示同时对多个关联模型（支持不同的关联类型）进行预载入查询。

<?php
declare (strict_types = 1);namespace appapicontroller;
use appmodelCollection as coll;class Collection
{public function saleColl(){$list = new coll();$User=coll::with('category')->find(1)->toArray();halt($User);//闭包---------------查询$users = coll::with(['category'	=> function($query) {$query->field('id,user_id,name,email');}])->select();foreach ($users as $user) {echo $user->profile->name;}}
}

方式二：动态绑定

<?php
declare (strict_types = 1);namespace appmodel;use thinkModel;class Collection extends Model
{public function index(){//使用appendRelationAttr，追加显示字段，官网的bindAttr查询显示null值$res = Collection::find(1)->appendRelationAttr('test',['cre_name'=>'name'])->toArray();halt($res);public function test(){return $this->hasone(Category::class,'id','cate_id');}
}

guzzle：

$toApi = "";//交易请求地址
$param = [];
$headers = ["Content-Type" => "application/json","X-HTTP-Method-Override" => "post","Content-Length"  => strlen(json_encode($param))];
$client = new Client();
$response = $client->request('post',$toApi,['headers' => $headers,'body'=>json_encode($param)]);
$result = json_decode($response->getBody()->getContents(),true);
var_dump($result);
