Description

BETA

Transplant rate-limiter. Laravel Cache components.

And added to\ Psr\ SimpleCache\ CacheInterface. The following methods have been added:

Increment

Decrement

Add

Put

Installation

Composer require wilbur-yu/hyperf-cache-ext

Configuration

1. Modify the cache configuration file:

'default' = > [' driver' = > WilburYu\ HyperfCacheExt\ Driver\ RedisDriver::class, 'packer' = > WilburYu\ HyperfCacheExt\ Utils\ Packer\ PhpSerializerPacker::class,' prefix' = > env ('APP_NAME',' skeleton').': cache:',], 'limiter' = > [' max_attempts' = > 5, / / maximum allowable times' decay_minutes' = > 1, / / current limiting unit time 'prefix' = >' counter-rate-limit:' / / key prefix 'for' = > [' common' = > static function (\ Hyperf\ HttpServer\ Contract\ RequestInterface $request) {return Limit::perMinute (3) },], 'key' = > ThrottleRequest::key (),]

For is the corresponding Laravel Facade RateLimiter::for (callable)

When the service starts, the listener collects the array of naming limiters for reference using the for parameter in the annotation. When the annotation section is executed, the current request instance\ Hyperf\ HttpServer\ Contract\ RequestInterface is injected into the named closure.

Key defaults to the current request fullUrl + ip. Supports strings and closures.

two。 Add to the exceptions configuration file:

\ WilburYu\ HyperfCacheExt\ Exception\ Handler\ CounterRateLimitException::class

Optional or can be caught by yourself. The exception comes with a getHeaders method with a value of: array ('XmurRateLimitMutual,' XmurRateLimitlyRemaining, 'Retry-After',' XRateLimitMuthReset`)

Use

Use counter speed limit annotation in controller

# [CounterRateLimitWithRedis (maxAttempts: 5, decayMinutes: 1)] or# [CounterRateLimit (for: "common")]

The annotation parameters are the same as the configuration file, and the priority is comment > configuration > default.

Max_attempts and decay_minutes do not work when using for.

If your cache driver is not redis, you can use CounterRateLimit annotations, otherwise use CounterRateLimitWithRedis annotations directly.

When using the speed limit in other places, you can use the auxiliary function counter_limiter (), using the same method as RateLimiter Facade in laravel. Please refer to the Laravel current limit document.

$executed = counter_limiter ()-> attempt ('send-sms:'.$user- > id,2,function () {/ / send sms logic}); if (! $executed) {return' Too many messages sentinel;} this is the end of the article on "how to install and configure the counter current limiting component of PHP Hyperf".
