Laravel对接SLS日志服务（写入和读取）
1、下载阿里云的sdk
#通过composer下载
composer require alibabacloud/aliyun-log-php-sdk
#对应的git仓库
https://github.com/aliyun/aliyun-log-php-sdk
2、创建sdk请求的service
<?php

use Aliyun_Log_Client;
use Aliyun_Log_Models_LogItem;
use Aliyun_Log_Models_PutLogsRequest;
use Aliyun_Log_Models_GetLogsRequest;
use Aliyun_Log_Models_GetHistogramsRequest;
use Exception;
use Illuminate\Support\Facades\Log;

{

$endpoint = env('ALIYUN_SLS_ENDPOINT');
$accessKeyId = env('ALIYUN_ACCESS_KEY_ID');
$accessKeySecret = env('ALIYUN_ACCESS_KEY_SECRET');
// 验证配置
if (!$endpoint || !$accessKeyId || !$accessKeySecret) {
throw new Exception('SLS configuration is missing');
}
// 初始化客户端
$this->client = new Aliyun_Log_Client($endpoint, $accessKeyId, $accessKeySecret);
$this->project = env('ALIYUN_SLS_PROJECT');
$this->logstore = env('ALIYUN_SLS_LOGSTORE');

}
3、创建config配置
# config/sls.config
<?php
return [
'aliyun' => [
'access_key_id' => env('ALIYUN_ACCESS_KEY_ID'),
'access_key_secret' => env('ALIYUN_ACCESS_KEY_SECRET'),
'sls' => [
'endpoint' => env('ALIYUN_SLS_ENDPOINT'),
'project' => env('ALIYUN_SLS_PROJECT'),
'logstore' => env('ALIYUN_SLS_LOGSTORE'),
],
],
];
4、从阿里云获取对应的配置填写在env
# .env,同阿里云账号下的服务器是允许内网访问的
ALIYUN_SLS_ENDPOINT=cn-shenzhen.log.aliyuncs.com
#内网
#ALIYUN_SLS_ENDPOINT=cn-shenzhen-intranet.log.aliyuncs.com
ALIYUN_SLS_PROJECT=
ALIYUN_ACCESS_KEY_ID=
ALIYUN_ACCESS_KEY_SECRET=
ALIYUN_SLS_LOGSTORE=
5、创建控制器进行验证
<?php
namespace App\Http\Controllers\Api;
use App\Http\Controllers\Controller;
use App\Jobs\Sugar;
use App\Services\SLSTimeSeriesService;
use Exception;
use Illuminate\Http\Request;
class MetricsController extends Controller
{
protected $slsService;
// 定义允许排序的字段
// 定义允许排序的字段和默认排序方式
protected $allowedSortFields = [
'__time__', // 日志时间
'__tag__:__receive_time__', // 接收时间
'timestamp', // 自定义时间戳
'user_id', // 自定义时间戳
];
public function __construct(SLSTimeSeriesService $slsService)
{
$this->slsService = $slsService;
}
/**

*/
public function store(Request $request)
{
try {
$data = [
'event' => 'user_login',
'user_id' => (string)$request->input('user_id', '1'),
'ip' => $request->ip(),
'timestamp' => (string)time(),
'request_data' => $request->all()
];
$this->slsService->putLogs($data);
return response()->json([
'success' => true,
'message' => 'Log stored successfully'
]);
} catch (Exception $e) {
return response()->json([
'success' => false,
'message' => $e->getMessage()
], 500);
}
}
//分页查询
public function index(Request $request)
{
try {
// 构建查询条件
$conditions = [];
if ($request->has('user_id')) {
$conditions[] = 'user_id = "' . $request->user_id . '"';
}

$sortField = '__time__';
}

$to = $request->input('to') ? strtotime($request->input('to')) : time();
// 记录查询参数

$result = $this->slsService->getLogs(
$query,
$from,
$to,
$page,
$perPage,
$sortOrder,
$sortField
);
return response()->json([
'success' => true,
'data' => $result['logs'],
'pagination' => $result['pagination'],
'query_info' => [
'query' => $query,
'conditions' => $conditions,
'sort' => [
'field' => $sortField,
'order' => $sortOrder
],
'from' => date('Y-m-d H:i:s', $from),
'to' => date('Y-m-d H:i:s', $to)
]
]);
} catch (Exception $e) {
return response()->json([
'success' => false,
'message' => $e->getMessage(),
'query_info' => [
'query' => $query ?? '*',
'conditions' => $conditions ?? []
]
], 500);
}
}
/**
* @param Request $request
* @return array
* @throws Exception
* 循环查询，速度慢，排序无限制，不分页
*/
public function all(Request $request)
{
// 时间范围
$from = $request->input('from') ? strtotime($request->input('from')) : time() - 3600;
$to = $request->input('to') ? strtotime($request->input('to')) : time();
// 自定义排序
$result = $this->slsService->getAllLogs(
'*',
$from,
$to,
'desc',
'timestamp'
);
return $result;
}
/**
* @param Request $request
* @return array
* @throws Exception
* sql查询，速度快，排序有限制，需要有索引才能查询出来，不分页
*/
public function allSql(Request $request)
{
$user_id = $request->input('user_id') ?? '';
// 时间范围
$from = $request->input('from') ? strtotime($request->input('from')) : time() - 3600;
$to = $request->input('to') ? strtotime($request->input('to')) : time();
$result = $this->slsService->getAllLogsSql(
'*',
$from,
$to,
$user_id,
'desc'
);
return $result;
}
}
