How to Implement Data Synchronization and Disaster Recovery for Baidu Wenxin Yiyan API in PHP Development

Baidu Wenxin Yiyan API provides a popular random sentence service, which can be used to display interesting sentences on websites. In PHP development, we can call the Baidu Wenxin Yiyan API interface to retrieve sentence data and show it on the page. However, to ensure data availability and a good user experience, we need to implement data synchronization and disaster recovery, so that users can still access the site normally in case of any issues.

Integrating Baidu Wenxin Yiyan API

First, you need to integrate Baidu Wenxin Yiyan API into your PHP project. You can use the cURL library to send HTTP requests and retrieve API data. Here’s an example code:

function getOneWord() {
    $url = 'https://v1.hitokoto.cn';
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    $response = curl_exec($ch);
    curl_close($ch);
    return json_decode($response, true);
}

$wordData = getOneWord();
if ($wordData && $wordData['status'] == 'success') {
    echo $wordData['hitokoto'];
} else {
    echo 'Failed to retrieve sentence';
}

The above code sends a request to the Baidu Wenxin Yiyan API using cURL, parses the JSON data received, and outputs the sentence to the webpage.

Data Synchronization

Data synchronization refers to saving the sentence data retrieved from the Baidu Wenxin Yiyan API into a database, so that we do not need to request the API every time. MySQL can be used as the storage database. Below is a simple example code:

$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";

$conn = new mysqli($servername, $username, $password, $dbname);
if ($conn->connect_error) {
    die("Database connection failed: " . $conn->connect_error);
}

$wordData = getOneWord();
if ($wordData && $wordData['status'] == 'success') {
    $hitokoto = $wordData['hitokoto'];
    $sql = "INSERT INTO hitokoto (content) VALUES ('$hitokoto')";
    if ($conn->query($sql) === TRUE) {
        echo "Data synchronization successful";
    } else {
        echo "Data synchronization failed: " . $conn->error;
    }
} else {
    echo 'Failed to retrieve sentence';
}
$conn->close();

This code saves the sentence retrieved from the API into a MySQL database in the "hitokoto" table. Every time a user visits the site, you can fetch a sentence from the database instead of requesting the API again.

Disaster Recovery

Disaster recovery refers to backing up data to servers located in different geographical locations to prevent single-point failures. You can achieve disaster recovery using MySQL master-slave replication. Below is a simple configuration example:

Configure the master server (master database):

[mysqld]
server-id=1
log-bin=mysql-bin
binlog-format=ROW

Configure the slave server (slave database):

[mysqld]
server-id=2
relay-log=mysql-relay-bin
log-slave-updates=1
read-only=1

Create a user on the master server for data synchronization and grant replication privileges:

CREATE USER 'replication'@'%' IDENTIFIED BY 'password';
GRANT REPLICATION SLAVE ON *.* TO 'replication'@'%';
FLUSH PRIVILEGES;

Execute the following command on the master server to get the current binary log filename and position:

SHOW MASTER STATUS;

On the slave server, configure the replication connection:

CHANGE MASTER TO MASTER_HOST='192.168.1.10', MASTER_USER='replication', MASTER_PASSWORD='password', MASTER_LOG_FILE='mysql-bin.000001', MASTER_LOG_POS=123;

Start the slave server’s replication functionality:

START SLAVE;

Once the configuration is completed, the data on the master server will automatically sync to the slave server. In case the master server fails, the slave server can immediately take over, ensuring service continuity.

Conclusion

Through the example code and configuration above, we can implement data synchronization and disaster recovery for Baidu Wenxin Yiyan API. This approach not only improves website performance but also ensures the site remains stable in the event of failure, enhancing the overall user experience.
