Wenxin Yiyan is an API service launched by Baidu that returns elegant classical Chinese, modern prose, or poetry, widely used for webpage footer content to enhance the site's emotional atmosphere. This article uses PHP as an example to explain how to integrate the Wenxin Yiyan API and implement real-time monitoring and performance optimization in a production environment.
First, you need to register a Baidu developer account and activate the service to obtain the API Key and Secret Key for API calls.
In PHP, you can use the curl library to send network requests and retrieve content from the API:
$url = 'https://api.lwl12.com/hitokoto/main/get';
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
$json = curl_exec($curl);
curl_close($curl);
$data = json_decode($json, true);
The returned data structure includes:
Front-end display can be as simple as:
<?php echo $data['hitokoto']; ?>
It is recommended to integrate monitoring platforms like New Relic or Datadog, which continuously track PHP program running status including response times, error tracking, and system resource usage.
<?php
require_once '/path/to/newrelic.php';
// Business logic code
?>
Configure the New Relic extension properly on your server to view API runtime data in the dashboard.
Using in-memory caching tools like Memcached or Redis can drastically reduce API call frequency. Here's an example implementation with Memcached:
$memcached = new Memcached();
$memcached->addServer('localhost', 11211);
$key = 'hitokoto';
$data = $memcached->get($key);
if (!$data) {
$json = file_get_contents('https://api.lwl12.com/hitokoto/main/get');
$data = json_decode($json, true);
$memcached->set($key, $data, 60 * 60);
}
This logic checks if the cache hits; if not, it fetches data from the API and updates the cache, effectively improving response speed.
CDNs cache static files like CSS and JS at global nodes, enhancing load speeds. For example, include CDN resources as follows:
<!DOCTYPE html>
<html>
<head>
<link href="https://cdnexample.com/style.css" rel="stylesheet" type="text/css">
<script src="https://cdnexample.com/script.js"></script>
</head>
<body>
</body>
</html>
With CDN deployed, users load resources from the nearest node, significantly reducing latency and enhancing experience.
This article explained how to integrate Baidu Wenxin Yiyan API with PHP, coupled with monitoring and optimization techniques, to build an efficient and stable API service. The combined use of caching and CDN can greatly improve response speed and system capacity, making it a highly recommended approach for production environments.
