Complete Guide to Integrating Baidu Smart Q&A API with PHP

Introduction

With the development of artificial intelligence, intelligent Q&A systems have become an essential part of many applications. The Baidu Smart Q&A API provides developers with a powerful interface, making it easy to integrate intelligent Q&A features into their applications. This article explains how to implement PHP code to integrate with the Baidu Smart Q&A API.

Obtain API Keys

First, visit the Baidu Smart Q&A Open Platform, create a new application, and obtain the API keys. These keys are used to authenticate requests and gain access. After creating your application, you will receive an APP ID, API Key, and Secret Key.

Install Dependencies

Before writing PHP code, ensure that the CURL extension is installed in your PHP environment. You can install it using the following command:

<span class="fun">sudo apt-get install php-curl</span>

Include Necessary Files

Create a new PHP file and include the Baidu AI SDK:

<?php
require_once 'AipOcr.php'; // Include the Baidu AI SDK file

// Define constants
const APP_ID = 'your_app_id';
const API_KEY = 'your_api_key';
const SECRET_KEY = 'your_secret_key';

// Initialize AipOcr object
$client = new AipOcr(APP_ID, API_KEY, SECRET_KEY);

// Other code...
?>

Replace APP_ID, API_KEY, and SECRET_KEY with the actual values obtained in the previous step.

Build Questions and Answers

Before calling the Baidu Smart Q&A API, you need to build the data structure for questions and answers. Example code:

<?php
// Build questions and answers array
$qaData = [
    'problems' => [
        'Question 1',
        'Question 2',
        'Question 3'
    ],
    'answers' => [
        'Answer 1',
        'Answer 2',
        'Answer 3'
    ]
];
?>

You can customize the questions and answers according to your application's requirements.

Call the Baidu Smart Q&A API

The following example demonstrates how to call the API and handle the response:

<?php
// Call Baidu Smart Q&A API
$result = $client->question($qaData);

// Handle API response
if (!empty($result['error_code'])) {
    // Handle error
    $errorCode = $result['error_code'];
    $errorMsg = $result['error_msg'];
    echo "API call error: {$errorCode} - {$errorMsg}";
} else {
    // Extract the answer
    $answer = $result['result']['question']['answer'];
    echo "Answer: {$answer}";
}
?>

$qaData is the array of questions and answers you built, and $result contains the API response, which can be processed as needed.

Conclusion

By following these steps, you can easily integrate Baidu Smart Q&A API using PHP. Leveraging the API allows you to add intelligent Q&A functionality to your applications. This guide provides a practical example to help developers get started quickly. For detailed information and additional parameters, refer to the official Baidu Smart Q&A API documentation.

This example is for reference only, and developers can extend and optimize it according to their specific project requirements.
