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.
classPasswordResetLinkControllerextendsController{publicfunctionsendResetLinkResponse(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 ofRoute::get('users/{user}/edit',function (User $user) {...})->middleware('can:edit,user');// you can do thisRoute::get('users/{user}/edit',function (User $user) {...})->can('edit''user');// PS: you must write UserPolicy to be able to do this in both cases

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');
