可以定时执行的事情
你可以让一些事情以每小时、每天，或是其他时间模式执行。
你可以安排 artisan 命令、作业类、可调用类、回调函数、甚至是 shell 脚本去定时执行。
use App\Jobs\Heartbeat;
$schedule->job(new Heartbeat)->everyFiveMinutes();
use App\Console\Commands\SendEmailsCommand;
$schedule->command('emails:send Taylor --force')->daily();
$schedule->command(SendEmailsCommand::class, ['Taylor', '--force'])->daily();
// First way ->with()
return view('index')
->with('projects', $projects)
->with('tasks', $tasks)
// Second way - as an array
return view('index', [
'projects' => $projects,
'tasks' => $tasks
]);
// Third way - the same as second, but with variable
$data = [
'projects' => $projects,
'tasks' => $tasks
];
return view('index', $data);
// Fourth way - the shortest - compact()
return view('index', compact('projects', 'tasks'));
调度标准 shell 命令
我们可以使用 scheduled command 调度标准 shell 命令
// app/Console/Kernel.php
class Kernel extends ConsoleKernel
{
protected function shedule(Schedule $shedule)
{
$shedule->exec('node /home/forge/script.js')->daily();
}
}
class MigrationsTest extends TestCase
{
public function test_successful_foreign_key_in_migrations()
{
// We just test if the migrations succeeds or throws an exception
$this->expectNotToPerformAssertions();
}
}
Str 的 mask 方法
Laravel 8.69发布了 Str::mask()方法，该方法使用重复字符屏蔽字符串的一部分.
class PasswordResetLinkController extends Controller
{
public function sendResetLinkResponse(Request $request)
{
$userEmail = User::where('email', $request->email)->value('email'); // username@domain.com
$maskedEmail = Str::mask($userEmail, '*', 4); // user***************
// If needed, you provide a negative number as the third argument to the mask method,
// which will instruct the method to begin masking at the given distance from the end of the string
$maskedEmail = Str::mask($userEmail, '*', -16, 6); // use******domain.com
}
}
// instead of
Route::get('users/{user}/edit', function (User $user) {
...
})->middleware('can:edit,user');
// you can do this
Route::get('users/{user}/edit', function (User $user) {
...
})->can('edit' 'user');
// PS: you must write UserPolicy to be able to do this in both cases
public function download(File $file)
{
// Initiate file download by redirecting to a temporary s3 URL that expires in 5 seconds
return redirect()->to(
Storage::disk('s3')->temporaryUrl($file->name, now()->addSeconds(5))
);
}
if (request()->has('since')) {
// example.org/?since=
// fails with illegal operator and value combination
$query->whereDate('created_at', '<=', request('since'));
}
if (request()->input('name')) {
// example.org/?name=0
// fails to apply query filter because evaluates to false
$query->where('name', request('name'));
}
if (request()->filled('key')) {
// correct way to check if get parameter has value
}
清理你臃肿的路由文件
清掉臃肿的路由文件，并将其拆分以保持组织有序
class RouteServiceProvider extends ServiceProvider
{
public function boot()
{
$this->routes(function () {
Route::prefix('api/v1')
->middleware('api')
->namespace($this->namespace)
->group(base_path('routes/api.php'));
Route::prefix('webhooks')
->namespace($this->namespace)
->group(base_path('routes/webhooks.php'));
Route::middleware('web')
->namespace($this->namespace)
->group(base_path('routes/web.php'));
if ($this->app->environment('local')) {
Route::middleware('web')
->namespace($this->namespace)
->group(base_path('routes/local.php'));
}
});
}
}
class VerifyLicense
{
public function handle(Request $request, Closure $next, $type = null)
{
$licenseKey = match ($type) {
'basic' => $request->getPassword(),
'bearer' => $request->bearerToken(),
default => $request->get('key')
};
// Verify license and return response based on the authentication type
}
}
// List all the files from a folder
$files = Storage::disk('origin')->allFiles('/from-folder-name');
// Using normal get and put (the whole file string at once)
foreach($files as $file) {
Storage::disk('destination')->put(
"optional-folder-name" . basename($file),
Storage::disk('origin')->get($file)
);
}
// Best: using Streams to keep memory usage low (good for large files)
foreach ($files as $file) {
Storage::disk('destination')->writeStream(
"optional-folder-name" . basename($file),
Storage::disk('origin')->readStream($file)
);
}
Sessions has() vs exists() vs missing()
你知道 Laravel 会话中的 has，exists 和 missing 方法吗？
// The has method returns true if the item is present & not null.
$request->session()->has('key');
// THe exists method returns true if the item ir present, event if its value is null
$request->session()->exists('key');
// THe missing method returns true if the item is not present or if the item is null
$request->session()->missing('key');
/** @test */
public function it_has_the_correct_value()
{
// ...
$response = $this->get('/some-route');
$this->assertEquals('John Doe', $response->viewData('name'));
}
/** @test */
public function it_contains_a_given_record()
{
// ...
$response = $this->get('/some-route');
$this->assertTrue($response->viewData('users')->contains($userA));
}
/** @test */
public function it_returns_the_correct_amount_of_records()
{
// ...
$response = $this->get('/some-route');
$this->assertCount(10, $response->viewData('users'));
}
使用 Redis 来统计页面浏览量
在处理高流量时，用 MySQL 统计像页面浏览量这样的东西可能会对性能造成相当大的影响。Redis 在这方面要好得多。你可以使用 Redis 和一个预定命令来保持与 MySQL 在一个固定的时间间隔内同步。
Route::get('{project:slug', function (Project $project) {
// Instead of $project->increment('views') we use Redis
// We group the views by the project id
Redis::hincrby('project-views', $project->id, 1);
})
// Console/Kernel.php
$schedule->command(UpdateProjectViews::class)->daily();
// Console/Commands/UpdateProjectViews.php
// Get all views from our Redis instance
$views = Redis::hgetall('project-views');
/*
[
(id) => (views)
1 => 213,
2 => 100,
3 => 341
]
*/
// Loop through all project views
foreach ($views as $projectId => $projectViews) {
// Increment the project views on our MySQL table
Project::find($projectId)->increment('views', $projectViews);
}
// Delete all the views from our Redis instance
Redis::del('project-views');

}
while ($user = User::where('id', '>', $processedUserId)->first()) {

// Your long work here to process user

$processedUserId = $user->id;
