Installation

1. Install through Composer (packagist)

# 在你的Laravel/Lumen项目的根目录下执行
composer require "hhxsv5/laravel-s:~1.0" -vvv
# 确保你的composer.lock文件是在版本控制中

2. Add service provider

Laravel: Modify the file config/app.php

'providers' => [
 //...
 Hhxsv5\LaravelS\Illuminate\LaravelSServiceProvider::class,
],

Lumen: Modify the file bootstrap/app.php

$app->register(Hhxsv5\LaravelS\Illuminate\LaravelSServiceProvider::class);

3. Publish the configuration file

php artisan laravels publish

Special case: You do not need to manually load the configuration laravels.php, the bottom layer of LaravelS has been loaded automatically.

// 不必手动加载，但加载了也不会有问题
$app->configure('laravels');

4. Modify the configuration config/laravels.php: monitoring IP, port, etc., please refer to Configuration Items.

Run

php artisan laravels {start|stop|restart|reload|publish}

##Commandstartstoprestartreloadpublish## is used with Nginx

upstream laravels {
 server 192.168.0.1:5200 weight=5 max_fails=3 fail_timeout=30s;
 #server 192.168.0.2:5200 weight=3 max_fails=3 fail_timeout=30s;
 #server 192.168.0.3:5200 backup;
}
server {
 listen 80;
 server_name laravels.com;
 root /xxxpath/laravel-s-test/public;
 access_log /yyypath/log/nginx/$server_name.access.log main;
 autoindex off;
 index index.html index.htm;
 
 # Nginx处理静态资源，LaravelS处理动态资源。
 location / {
  try_files $uri @laravels;
 }

 location @laravels {
  proxy_http_version 1.1;
  # proxy_connect_timeout 60s;
  # proxy_send_timeout 60s;
  # proxy_read_timeout 120s;
  proxy_set_header Connection "keep-alive";
  proxy_set_header X-Real-IP $remote_addr;
  proxy_set_header Host $host;
  proxy_pass http://laravels;
 }
}

Instructions
Start LaravelS and display the list of started processes ps -ef|grep laravels
Stop LaravelS
Restart LaravelS
Restart all worker processes smoothly, These worker processes contain your business code and framework (Laravel/Lumen) code and will not restart the master/manger process
Publish the configuration file to your In the project, config/laravels.php

Listening events

Usually, you can reset or destroy some global or static variables in these events, or modify the current request and response.

laravels.received_request After converting swoole_http_request into Illuminate\Http\Request, before the Laravel kernel processes the request.

// 修改`app/Providers/EventServiceProvider.php`, 添加下面监听代码到boot方法中
// 如果变量$exents不存在，你也可以调用\Event::listen()。
$events->listen('laravels.received_request', function (\Illuminate\Http\Request $req) {
 $req->query->set('get_key', 'hhxsv5');// 修改querystring
 $req->request->set('post_key', 'hhxsv5'); // 修改post body
});

laravels.generated_response After the Laravel kernel processes the request, Illuminate\Http\Response is converted into swoole_http_response (the next step will be to respond to the client).

$events->listen('laravels.generated_response', function (\Illuminate\Http\Request $req, \Symfony\Component\HttpFoundation\Response $rsp) {
 $rsp->headers->set('header-key', 'hhxsv5');// 修改header
});

Use swoole_http_server instance in your project

/**
* @var \swoole_http_server
*/
$swoole = app('swoole');// Singleton
var_dump($swoole->stats());

Notes

Recommended through Illuminate\Http \Request object to obtain request information, compatible with $_SERVER, $_GET, $_POST, $_FILES, $_COOKIE, $_REQUEST, $_SESSION, $_ENV cannot be used.

public function form(\Illuminate\Http\Request $request)
{
 $name = $request->input('name');
 $all = $request->all();
 $sessionId = $request->cookie('sessionId');
 $photo = $request->file('photo');
 $rawContent = $request->getContent();
 //...
}

It is recommended to respond to the request by returning the Illuminate\Http\Response object, which is compatible with echo, vardump(), and print_r(). You cannot use functions like exit() and

die()、header()、setcookie()、http_response_code()。
public function json()
{
 return response()->json(['time' => time()])->header('header1', 'value1')->withCookie('c1', 'v1');
}

Globally declared by you , static variables must be manually cleaned or reset.

Infinitely appending elements to static or global variables will cause the memory to become full.

// 某类
class Test
{
 public static $array = [];
 public static $string = '';
}

// 某控制器
public function test(Request $req)
{
 // 内存爆满
 Test::$array[] = $req->input('param1');
 Test::$string .= $req->input('param2');
}

TODO

##Connection pool for MySQL/Redis.

• Coroutine client that wraps MySQL/Redis/Http.
