How to implement data backup and recovery of Baidu Wenxin Yiyan API in PHP development?

Introduction:
Baidu Wenxin Yiyan is an API interface that provides a random access to a poem sentence. During the development process, we may use this interface to obtain data. If the amount of data is large, we may need to back up the data for later restoration. This article will introduce how to implement the backup and recovery function of Baidu Wenxinyiyan API data in PHP development.

1. Data backup
   To implement data backup of Baidu Wenxin Yiyan API, we first need to save the obtained data to a local file or database. The following is a sample code that saves data to a local file:

<?php
// 请求API接口，获取一句诗句
$url = 'https://v1.jinrishici.com/all';
$response = file_get_contents($url);
$data = json_decode($response, true);

if ($data && isset($data['status']) && $data['status'] == 'success') {
    // 获取诗句内容
    $sentence = $data['data']['content'];

    // 将诗句保存到本地文件
    $filename = 'backup.txt';
    file_put_contents($filename, $sentence);
    echo '数据备份成功！';
} else {
    echo '获取数据失败！';
}
?>

This code first sends a request to obtain the data of a poem, and then saves the poem to the local file backup.txt. You can also choose to save the data to the database according to your needs.

2. Data Recovery
   When we need to restore data from backup, we can obtain the previously saved verse data by reading the backup file. The following is a sample code that reads the backup file and outputs the verses:

<?php
// 读取备份文件
$filename = 'backup.txt';
$sentence = file_get_contents($filename);

if (!empty($sentence)) {
    echo '恢复的诗句：'.$sentence;
} else {
    echo '未找到备份数据！';
}
?>

This code reads the contents of the backup file backup.txt and outputs the verses to the page.

Note: In actual development, we may need to back up data regularly, so we can use scheduled tasks or scheduled tasks to automatically perform backup operations.

Conclusion:
Through the above sample code, we can realize the data backup and recovery functions of Baidu Wenxin Yiyan API. Backing up data can ensure that even if data is lost due to server failure or other unexpected circumstances, we can still restore and use the previous verse data. At the same time, backup data can also be used for data analysis, statistics and other purposes, providing more possibilities and convenience for our development work.
