How to implement the data caching and update strategy of Baidu Wenxin Yiyan interface in PHP development?

Baidu Wenxinyiyan is a very popular random sentence generation interface that can be used to decorate the website or display some interesting text.

However, when we use this interface, on the one hand, we must ensure the randomness of the generated sentences, and on the other hand, we must avoid frequent requests to the interface to save bandwidth and improve response speed. Therefore, during the development process, we can consider caching the interface data and implementing a regular update strategy.

1. Caching strategy

In PHP development, we can use caching to improve data access speed. For data from Baidu Wenxin Yiyan interface, we can choose to cache it in files, databases or memory.

1. Cache to file

This is a simple and effective caching method. We can save the data returned by Baidu Wenxin Yiyan interface to a text file, and then read the data directly from the file when needed.

Sample code:

// 缓存文件路径
$cacheFile = 'cache/words.txt';

// 判断缓存文件是否存在
if (file_exists($cacheFile)) {
    // 判断缓存文件是否过期（可以根据具体需求设置缓存的有效期）
    if (time() - filemtime($cacheFile) < 3600) {
        // 从缓存文件中读取数据
        $words = file_get_contents($cacheFile);
    } else {
        // 缓存文件过期，重新请求接口获取数据
        $words = file_get_contents('https://api.xxxxx.com/word/api');
        
        // 保存数据到缓存文件
        file_put_contents($cacheFile, $words);
    }
} else {
    // 缓存文件不存在，请求接口获取数据并保存到缓存文件
    $words = file_get_contents('https://api.xxxxx.com/word/api');
    file_put_contents($cacheFile, $words);
}

// 使用获取到的数据
echo $words;

2. Cache to database

If a database has been used in your project, cache the data of Baidu Wenxinyiyan , you can save it to a database table.

Sample code:

// 数据库配置
$dbHost = 'localhost';
$dbUsername = 'root';
$dbPassword = '123456';
$dbName = 'mydatabase';

// 连接数据库
$conn = mysqli_connect($dbHost, $dbUsername, $dbPassword, $dbName);

// 查询缓存数据
$result = mysqli_query($conn, 'SELECT * FROM cache_table WHERE id = 1');
if ($row = mysqli_fetch_assoc($result)) {
    // 判断缓存是否过期
    if (time() - strtotime($row['update_time']) < 3600) {
        // 使用缓存数据
        $words = $row['words'];
    } else {
        // 缓存过期，重新请求接口获取数据
        $words = file_get_contents('https://api.xxxxx.com/word/api');
        
        // 更新数据库缓存数据
        mysqli_query($conn, 'UPDATE cache_table SET words = "'.$words.'", update_time = "'.date('Y-m-d H:i:s').'" WHERE id = 1');
    }
} else {
    // 缓存表不存在或者没有数据，请求接口获取数据并保存到数据库
    $words = file_get_contents('https://api.xxxxx.com/word/api');
    mysqli_query($conn, 'INSERT INTO cache_table (id, words, update_time) VALUES (1, "'.$words.'", "'.date('Y-m-d H:i:s').'")');
}

// 使用获取到的数据
echo $words;

// 关闭数据库连接
mysqli_close($conn);

2. Update strategy

In order to ensure the freshness of the data, we can develop an update strategy to regularly update the data in the cache. You can set the update frequency according to the actual situation, such as updating once every hour.

Sample code:

// 缓存策略
$cacheFile = 'cache/words.txt';
$updateInterval = 3600; // 更新间隔时间（单位：秒）

// 判断缓存文件是否存在
if (file_exists($cacheFile)) {
    // 判断缓存文件是否过期
    if (time() - filemtime($cacheFile) >= $updateInterval) {
        // 缓存文件过期，重新请求接口获取数据
        $words = file_get_contents('https://api.xxxxx.com/word/api');
        
        // 保存数据到缓存文件
        file_put_contents($cacheFile, $words);
    } else {
        // 从缓存文件中读取数据
        $words = file_get_contents($cacheFile);
    }
} else {
    // 缓存文件不存在，请求接口获取数据并保存到缓存文件
    $words = file_get_contents('https://api.xxxxx.com/word/api');
    file_put_contents($cacheFile, $words);
}

// 使用获取到的数据
echo $words;

The above is the sample code to implement the data caching and update strategy of Baidu Wenxin Yiyan interface in PHP development. By rationally using caching and regular update strategies, you can improve website performance and user experience while ensuring the freshness of data.
