用Laravel也有不短的工夫了，也用过不少版本了，以下代码是在日常我的项目中收集，作为笔记，也分享进去，心愿对你有点用途。
注：版本没标注，若有不兼容的问题，微调即可。
验证
不太习惯独自弄个Request验证类，比拟习惯上面的写法：
use Illuminate\Http\Request;use Illuminate\Support\Facades\Validator; $inputData = $request->only(['name', 'address', 'mobile', 'draw_id']); $messages = [ 'required'=>':attribute为必填项', 'int'=>':attribute参数类型谬误', 'max'=>':attribute长度不得超过 :size', ]; $validator = Validator::make($inputData, [ 'draw_id' => 'required|int', 'name' => 'required', 'mobile' => 'required', 'address' => 'required', ], $messages,[ 'name'=>'收货人姓名', 'mobile'=>'手机号码', 'address'=>'收货地址', ]); if ($validator->fails()) { return self::response([], current($validator->errors()->all()), 2); }自定义验证
比方罕用的手机号验证：
php artisan make:rule Mobile而后改一下：
/** * Mobile次要代码 * 验证是否通过 * * @param string $attribute * @param mixed $value * @return bool */ public function passes($attribute, $value) { // return preg_match('/^1\d{10}$/', $value); } /** * 错误信息 * * @return string */ public function message() { return '手机号格局不正确'; }而后这么用起来：
$columns = [ 'college' => 'required|max:32', 'mobile' => ['required', new Mobile()], 'qq' => 'required',];ORM
关联查问
- 一对一
// Model定义，关联外键class User extends Model{ ... public function userIntegral() { return $this->hasOne('App\Models\UserIntegral', 'user_id', 'id'); }}// 应用with查问(new User())->with('userIntegral')->orderBy('id', 'desc')->paginate($limit);- 一对多
//Modelnamespace App\Models;use Illuminate\Database\Eloquent\Model;class Hotel extends Model{ public function orders() { return $this->hasMany('App\Models\Order'); }}//应用，比方查问某个Hotel下status=30的Order$hotel = Hotel::with(['orders' => function ($query) { $query->where('status', 30); }])->find(4);对立异样解决
这个能够参见之前的文章Laravel 对立错误处理为 JSON
队列
失败队列入库
- 生成表
生成failed_jobs表
php artisan queue:failed-tablephp artisan migrate- 独自解决
能够在Job中独自解决失败，Job失败也会写入下面生成的failed_jobs表
/*** 工作失败的处理过程** @param Exception $exception* [@return](https://learnku.com/users/31554) void*/public function failed(Exception $exception){ // 解决}重试队列
有时候代码有破绽可能会有队列执行失败的情况，这时候咱们就须要重试。
- 查看所有失败
php artisan queue:failed- 重试所有失败
php artisan queue:retry all- 重试单个失败
php artisan queue:retry 13- 清空失败（重要的队列数据万不可这么操作）
php artisan queue:flush另外，手动去操作的确不太不便，你能够设置个cron，定时重试所有失败，但务必要留神音讯揭示，免得队列始终重试始终失败，往返运行，影响了失常的队列性能。
其余罕用代码
文件上传OSS
<?phpnamespace App\Http\Controllers;use Illuminate\Http\Request;use Controller;use Illuminate\Support\Facades\Storage;use Illuminate\Support\Facades\Validator;use OSS\OssClient;use OSS\Core\OssException;class UploadController extends Controller{ public function index(Request $request) { $file = $request->file('file'); if ($file->isValid()) { $ext = $file->getClientOriginalExtension(); $realPath = $file->getRealPath(); $filepath = config('app.env').'/' . md5(uniqid('', true)); $result = $this->uploadOss($realPath, $filepath.".".$ext); if ($result['code']) { return response(['code' => 2, 'msg' => $result['msg']]); } else { return response(['code' => 0, 'msg' => '上传胜利', 'data' => [ 'filepath' => $result['data']['url'], 'data' => $request->all() ]]); } } } /** * 上传oss * @param $filePath 以后门路 * @param $object 预约义文件名，可含文件夹 * [@return](https://learnku.com/users/31554) array */ public function uploadOss($filePath, $object) { $accessKeyId = config('filesystems.disks')[config('filesystems.default')]['access_key']; $accessKeySecret = config('filesystems.disks')[config('filesystems.default')]['secret_key']; $endpoint = config('filesystems.disks')[config('filesystems.default')]['endpoint']; $bucket= config('filesystems.disks')[config('filesystems.default')]['bucket']; $url = config('filesystems.disks')[config('filesystems.default')]['host']; try{ $ossClient = new OssClient($accessKeyId, $accessKeySecret, $endpoint); $ossClient->uploadFile($bucket, $object, $filePath); return [ 'code' => 0, 'data' => [ 'url' => $url.'/'.$object ] ]; } catch(OssException $e) { return [ 'code' => 1, 'msg' => $e->getMessage() ]; } }}// -------// 配置'oss' => [ 'driver' => 'oss', 'root' => '', 'access_key' => env('OSS_ACCESS_KEY'), 'secret_key' => env('OSS_SECRET_KEY'), 'endpoint' => env('OSS_ENDPOINT'), // 应用 ssl 这里设置如: https://oss-cn-beijing.aliyuncs.com 'bucket' => env('OSS_BUCKET'), 'isCName' => env('OSS_IS_CNAME', false), // 如果 isCname 为 false，endpoint 应配置 oss 提供的域名如：`oss-cn-beijing.aliyuncs.com`，否则为自定义域名，，cname 或 cdn 请自行到阿里 oss 后盾配置并绑定 bucket 'host' => env('OSS_HOST', '')],json输入
protected static $code = 0;protected static $msg = 'ok';public function response($data = [], $msg = '', $code = 0){ if (is_null($data)) { $data = new \stdClass(); } return response()->json([ 'code' => $code? $code : self::$code, 'msg' => $msg? $msg : self::$msg, 'data' => $data, ], 200);}过程锁
- 一般版本
// $autoDel字段删除，$ttl 过期工夫，秒public function processLock($key, $autoDel = true, $ttl = 60){ $key = 'processLock:'.$key; // 不同版本或redis扩大，会有稍微不同，自行调整下代码即可 if (Redis::Command('set', [$key, 1, 'EX', $ttl, 'NX'])) { if ($autoDel) { register_shutdown_function(function () use ($key) { Redis::del($key); }); } return true; } return false;}- lua版本
public function getScript() { return <<<LUA local ret = redis.call("setnx", KEYS[1], ARGV[1]) if ret == 1 then return redis.call("expire", KEYS[1], ARGV[2]) else return 0 endLUA; } public function processLock($key, $autoDel = true, $ttl = 60) { if (Redis::eval($this->getScript(), 1, $key, 1, $ttl)) { if ($autoDel) { register_shutdown_function(function () use ($key) { Redis::del($key); }); } return true; } return false; }阐明：Redis::eval行第一个1示意key的数量，是为了辨别KEYS和ARGV。

零碎告诉到钉钉
咱们能够应用队列，把一些重要的告诉投到钉钉，次要代码如下：
<?phpnamespace App\Jobs;use Illuminate\Bus\Queueable;use Illuminate\Contracts\Queue\ShouldQueue;use Illuminate\Foundation\Bus\Dispatchable;use Illuminate\Queue\InteractsWithQueue;use Illuminate\Queue\SerializesModels;use Illuminate\Support\Facades\Log;use GuzzleHttp\Client;class SystemNotify implements ShouldQueue{ use Dispatchable, InteractsWithQueue, Queueable, SerializesModels; private $title; private $content; private $type; private $robot; const DD_URL = 'https://oapi.dingtalk.com'; /** * Create a new job instance. * * @param $title * @param string $content * @param string $type text, markdown * @param int $robot */ public function __construct($title, $content = '', $type = 'markdown', $robot = 1) { // 独自应用SystemNotify队列 $this->queue = 'SystemNotify'; $this->title = $title; $this->content = $content; $this->type = $type; $this->robot = $robot; } /** * Execute the job. * * @return void */ public function handle() { // 能够不应用关键字，倡议钉钉机器人应用IP段设置，更为平安 switch ($this->type){ case 'markdown': $params = [ 'msgtype' => $this->type, $this->type => [ 'title' => $this->title.'[关键字]', 'text' => $this->content ] ]; break; default: $params = [ 'msgtype' => $this->type, $this->type => [ 'content' => $this->content.'[关键字]', ] ]; break; } $params = json_encode($params, JSON_UNESCAPED_UNICODE); $uri = self::URL_MAPPING[$this->robot]; $this->getClient()->request('POST', $uri, [ 'headers' => [ 'Content-Type' => 'application/json;charset=utf-8' ], 'body' => $params ]); } // 对应不同的钉钉群告诉，批改access_token参数即可 const URL_MAPPING = [ 1 => '/robot/send?access_token=@1', 2 => '/robot/send?access_token=@2' ]; public function getClient() { return new Client([ 'base_uri' => 'https://oapi.dingtalk.com', 'timeout' => 30, 'verify' => false ]); }}阐明：告诉内容能够自定义，增加智能机器人操作比较简单就不赘述了
