PHP, as a widely-used server-side language, can easily connect to this API to obtain data. This article explains how to use PHP with cURL to call the Baidu Wenxin Yiyan API and parse the returned JSON data.

The example demonstrates setting the temperature parameter to 0.6 to retrieve a high-quality daily quote.

2. Preparations

Before writing code, you need to complete the following preparations:

2.1. Apply for API Key

Visit the Baidu Cloud official website, register and log in, create an application selecting Baidu Wenxin Yiyan service, then generate and save the API key for use.

2.2. Install cURL Extension

PHP uses the cURL extension to make HTTP requests. Make sure your server environment has cURL installed. Example installation on Linux:

sudo apt-get install php-curl

or

sudo yum install php-curl

After installation, restart your PHP service to enable the extension.

3. Connect to Baidu Wenxin Yiyan API

The following PHP code demonstrates how to send a request to Baidu Wenxin Yiyan API using cURL and retrieve the daily quote:

// Baidu Wenxin Yiyan API URL
$url = 'https://v1.hitokoto.cn/?c=a&encode=json';
// Insert your API key
$api_key = 'YOUR_API_KEY';
// Initialize cURL session
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('apikey:' . $api_key));
// Execute request and get response
$response = curl_exec($ch);
// Close cURL session
curl_close($ch);
// Decode JSON data
$data = json_decode($response, true);
// Output the daily quote
echo $data['hitokoto'];

The code sets the request URL and includes the API key in the HTTP headers to ensure authentication. It then parses the JSON response and outputs the "hitokoto" field, which is the daily quote.
