How to effectively handle the caching problem of tokens in PHP to reduce the number of API requests?

Optimize the PHP Token cache mechanism and reduce the frequency of API calls
In PHP projects, especially when third-party interfaces such as WeChat APIs are involved, efficient management of tokens is crucial. This article provides optimization solutions for the token caching problem, effectively reducing the number of API requests.
Problems with existing code: storing the token in the Session, and the logic is flawed. Session storage is not suitable for high concurrency scenarios, and the if-else structure in the code causes the first request to always get the token, and the business logic cannot be directly executed. In addition, the 120-second expiration time is too short, and frequent refresh of tokens has increased API requests.
Improvement solution: adopt file caching mechanism and optimize code logic
Using file caching can avoid concurrency issues and performance bottlenecks in Session. The file content format is cache_time access_token and is updated regularly. In order to avoid concurrent read and write conflicts, a file lock mechanism is adopted.
Improved code:
<?php header("Content-type:text/html;charset=utf-8");
$cacheFile = __DIR__ . '/access_token.cache'; // cache file path function getAccessToken($appId, $appSecret) {
$tokenUrl = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid={$appId}&secret={$appSecret}";
$ch = curl_init();
curl_setopt_array($ch, [
CURLOPT_URL => $tokenUrl,
CURLOPT_SSL_VERIFYPEER => false,
CURLOPT_SSL_VERIFYHOST => false,
CURLOPT_RETURNTRANSFER => true,
]);
$response = curl_exec($ch);
curl_close($ch);
$data = json_decode($response, true);
if (isset($data['access_token'])) {
return $data;
} else {
return false; // Failed to obtain the token}
}
function cacheAccessToken($accessToken, $expireTime) {
global $cacheFile;
$data = "{$expireTime} {$accessToken}";
if (!file_exists($cacheFile)) {
touch($cacheFile);
}
if (flock($cacheFile, LOCK_EX)) { // Get exclusive lock file_put_contents($cacheFile, $data);
flock($cacheFile, LOCK_UN); // Release the lock}
}
function getCachedAccessToken() {
global $cacheFile;
if (file_exists($cacheFile)) {
if (flock($cacheFile, LOCK_SH)) { // Get the shared lock $data = file_get_contents($cacheFile);
flock($cacheFile, LOCK_UN); // Release the lock list($cacheTime, $accessToken) = exploit(' ', $data, 2);
if (time() <p> <strong>Further optimization: Use Redis or Memcached</strong></p><p> For high concurrency scenarios, it is recommended to use distributed caches such as Redis or Memcached, which provide higher performance and reliability. This requires modifying the code to use the corresponding cache client library.</p><p> <strong>Timing tasks:</strong></p><p> It is recommended to add a timed task (for example, using crontab), execute the script every 7000 seconds (or less, depending on the actual situation), and refresh the token cache. This ensures that the token is always valid and avoids API request failures due to cache expiration.</p><p> Through the above improvements, the Token cache can be effectively managed, unnecessary API requests can be reduced, and system performance and stability can be improved. Which caching scheme to choose depends on the size and requirements of the project. For small projects, file cache plus timing tasks are a good choice; for large projects, Redis or Memcached is a more ideal solution.</p>The above is the detailed content of How to effectively handle the caching problem of tokens in PHP to reduce the number of API requests?.

Java Chinese garbled problem, cause and fix for garbled code
May 28, 2025 pm 05:36 PM
The garbled problem in Java Chinese is mainly caused by inconsistent character encoding. The repair method includes ensuring the consistency of the system encoding and correctly handling encoding conversion. 1.Use UTF-8 encoding uniformly from files to databases and programs. 2. Clearly specify the encoding when reading the file, such as using BufferedReader and InputStreamReader. 3. Set the database character set, such as MySQL using the ALTERDATABASE statement. 4. Set Content-Type to text/html;charset=UTF-8 in HTTP requests and responses. 5. Pay attention to encoding consistency, conversion and debugging skills to ensure the correct processing of data.

How to limit user resources in Linux? How to configure ulimit?
May 29, 2025 pm 11:09 PM
Linux system restricts user resources through the ulimit command to prevent excessive use of resources. 1.ulimit is a built-in shell command that can limit the number of file descriptors (-n), memory size (-v), thread count (-u), etc., which are divided into soft limit (current effective value) and hard limit (maximum upper limit). 2. Use the ulimit command directly for temporary modification, such as ulimit-n2048, but it is only valid for the current session. 3. For permanent effect, you need to modify /etc/security/limits.conf and PAM configuration files, and add sessionrequiredpam_limits.so. 4. The systemd service needs to set Lim in the unit file
