整合日志到ES

1、elasticsearch的安装就跳过了，打开http://127.0.0.1:9200/如下，再继续

{
  "name": "PC-201902071414",
  "cluster_name": "elasticsearch",
  "cluster_uuid": "_lqn19mvSx-SwSeyRHwYvA",
  "version": {
    "number": "7.3.0",
    "build_flavor": "default",
    "build_type": "zip",
    "build_hash": "de777fa",
    "build_date": "2019-07-24T18:30:11.767338Z",
    "build_snapshot": false,
    "lucene_version": "8.1.0",
    "minimum_wire_compatibility_version": "6.8.0",
    "minimum_index_compatibility_version": "6.0.0-beta1"
  },
  "tagline": "You Know, for Search"
}

2、过程：
本来想自己写的，也找了很多博客，但是好像都是5.5版的Laravel，也不知道是否有效就不贴链接了；偶然发现monolog下有vendor/monolog/monolog/src/Monolog/Handler/ElasticSearchHandler.php，又发现实例化时需要Elastica\Client，所以先下包

sudo composer require ruflin/elastica

3、Talk is cheap：

.env

ELASTIC_HOST=127.0.0.1:9200
ELASTIC_LOG_INDEX=blog
ELASTIC_LOG_TYPE=log

config/services.php

<?php
return [
    ……

    ]

            'ignore_exceptions' => false,
        ],

        'es' => [
            'driver' => 'custom',
            'via' => App\Ship\Logging\ESLogger::class,

            'index' => env('ELASTIC_LOG_INDEX', 'blog'),
            'type' => env('ELASTIC_LOG_TYPE', 'log'),
        ],
      ……
];

app/Ship/Logging/ESLogger.php

<?php

use Monolog\Logger;
use Monolog\Handler\ElasticSearchHandler;

{
    /**

        $client = app('es');
        $handler = new ElasticSearchHandler($client, $config);
        return new Logger('es', [$handler]);
    }
}

app/Providers/ESServiceProvider.php

<?php

use Elastica\Client;
use Illuminate\Support\ServiceProvider;

    {
        $this->app->singleton('es', function () {
            return new Client(config('services.es'));
        });
    }

}

routes/web.php

<?php
use Illuminate\Support\Facades\Route;

Route::get('/test/logging', function () {
    Illuminate\Support\Facades\Log::info(
        'ElasticSearch写入日志！',
        [
            'code' => 200,
            'msg' => '不错，成功了！',
            'data' => [
                'user' => 'TruckCoder'
            ]
        ]
    );

    $client = app('es');
    $query = '{"query":{"match":{"message":"写入日志"}}}';
    $index = $client->getIndex(config('logging.channels.es.index'));
    $type = $index->getType(config('logging.channels.es.type'));

    $path = $index->getName() . '/' . $type->getName() . '/_search';
    $response = $client->request($path, Elastica\Request::GET, $query);
    $responseArray = $response->getData();
    return $responseArray;
});
