laravel5.1 项目开发常用接口

一、路由定义

 app/Http/routes.php

 

Route::get();

e.g. Route::get('foo','Photos\AdminController@method');

Route::post();

Route::put();

Route::delete();

为多种请求注册路由

Route::match();

e.g. 

Route::match(['get','post'],'/',function(){return'Hello World';});

注册路由响应所有 HTTP 请求

Route::any();

参数

Route::get('user/{id}',function($id){return'User '.$id;});

 

详见：http://www.golaravel.com/laravel/docs/5.1/routing/#route-parameters     

 

二、项目

1、数据库操作

useDB;

DB::select('select * from users where id = ?', [1]);

DB::insert('insert into users (id, name) values (?, ?)', [1, 'Dayle']);

DB::update('update users set votes = 100 where name = ?', ['John']);

DB::delete('delete from users');

DB::table('users')->select('name','email')->get();

DB::table('users')->distinct()->get();

DB::table('users')->orderBy('name','desc')->groupBy('count')->having('count','>',100)->get();

DB::table('users')->join('contacts','users.id','=','contacts.user_id')->join('orders','users.id','=','orders.user_id')->select('users.id','contacts.phone','orders.price')->get();

聚合方法

$users=DB::table('users')->count();

$price=DB::table('orders')->max('price');

$price=DB::table('orders')->min('price');

$price=DB::table('orders')->avg('price');

$total=DB::table('users')->sum('votes');

DB::table('users')->insert([['email'=>'[email protected]','votes'=>0],['email'=>'[email protected]','votes'=>0]]);

DB::table('users')->where('id',1)->update(['votes'=>1]);

DB::table('users')->increment('votes');DB::table('users')->increment('votes',5);DB::table('users')->decrement('votes');DB::table('users')->decrement('votes',5);

DB::table('users')->increment('votes',1,['name'=>'John']);

DB::table('users')->where('votes', '<', 100)->delete();

DB::table('users')->delete();

DB::table('users')->truncate();

 

事务：

DB::transaction(function()

{

DB::table('users')->update(['votes' => 1]);

DB::table('posts')->delete();

});

 

DB::beginTransaction();

DB::rollback();

DB::commit();

 

详见：

http://www.golaravel.com/laravel/docs/5.1/queries/

http://www.golaravel.com/laravel/docs/5.1/database/

 

Model类

 

all()

create(array $attributes = [])

update(array $attributes = [])

destroy($ids)

delete()

update(array $attributes = [])

save(array $options = [])

toJson($options = 0)

jsonSerialize()

toArray()

asJson($value)

fromJson($value, $asObject = false)

 

 

2、view()

e.g.  

returnview('admin.profile',$data);

returnview('greetings',['name'=>'Victoria']);

$view=view('greeting')->with('name','Victoria');

详见：http://www.golaravel.com/laravel/docs/5.1/views/

 

三、日志写入

Log::emergency($error);

Log::alert($error);

Log::critical($error);

Log::error($error);

Log::warning($error);

Log::notice($error);

Log::info($error);

Log::debug($error);

 

四、缓存写入

 

保存对象到缓存中  

Cache::put('key','value',$minutes);

使用 Carbon 对象配置缓存过期时间

$expiresAt=Carbon::now()->addMinutes(10);Cache::put('key','value',$expiresAt);

确认对象是否存在

Cache::has('key')

 

从缓存中取得对象

$value=Cache::get('key');

从缓存中删除对象

Cache::forget('key');
