How to Avoid PHP Triggering Frequency Limits When Calling Kuaishou API: Best Practices

Overview

In the development process, we often need to use Kuaishou's API to get user information, publish content, and so on. However, Kuaishou has frequency limits for API calls, and if you exceed the allowed number of calls, your API access may be temporarily suspended or restricted. To avoid this, this article will share how to handle Kuaishou API frequency limits in PHP, so that API calls won't be blocked.

Set a Reasonable Interval

The frequency limits of Kuaishou API calls are typically time-based. Therefore, we can set a fixed time interval before each API call to ensure we don't exceed the limit. Here's a PHP code example:

function callKwaiApi($url) {
    // Set the call interval to 1 second
    $interval = 1;

    // Get the time of the last API call
    $lastCallTime = getLastCallTime(); // This needs to be implemented based on your actual situation

    // Calculate the time interval since the last API call
    $timeInterval = time() - $lastCallTime;

    // If the time interval is less than the call interval, wait
    if ($timeInterval < $interval) {
        sleep($interval - $timeInterval);
    }

    // Make the API request
    $response = requestApi($url); // This needs to be implemented based on your actual situation

    // Update the time of the last API call
    updateLastCallTime(); // This needs to be implemented based on your actual situation

    return $response;
}

In this code, we get the time of the last API call and calculate the time difference from the current time. If the time difference is less than 1 second, we use PHP's sleep function to wait, ensuring that the interval between each call meets Kuaishou's API limits.

Managing Requests with a Queue

If there are multiple API requests in the system that need to be sent, we can put these requests into a queue and process them one by one. Here's a PHP code example for handling a queue:

function addRequestToQueue($request) {
    // Add the request to the queue
    $queue = getQueue(); // This needs to be implemented based on your actual situation
    $queue->push($request);
}

function processQueue() {
    // Get the next request from the queue
    $queue = getQueue(); // This needs to be implemented based on your actual situation
    $request = $queue->pop();

    // Make the API request
    $response = requestApi($request); // This needs to be implemented based on your actual situation

    // Process the API response
    processResponse($response); // This needs to be implemented based on your actual situation

    // Continue processing the next request
    processQueue();
}

By putting API requests into a queue and processing them in sequence, we can ensure that at any given time only one request is calling Kuaishou's API, avoiding triggering the frequency limits.

Conclusion

When using Kuaishou's API, it is crucial to handle the frequency limits properly to avoid being blocked or restricted. This article covered two common methods for managing API call frequency: setting time intervals and using a queue to manage requests. By using these methods, we can effectively avoid frequency limits and ensure smooth interaction with Kuaishou's API.

Note that the above techniques and code are for reference only. When implementing, you should adjust and optimize based on your actual situation. Always refer to the official Kuaishou API documentation and comply with their guidelines to avoid unnecessary risks.
