PHP を使用して Baidu 画像認識 API に接続する方法を段階的に説明します。

composer require baidu/aip-sdk

<?php
require 'vendor/autoload.php';

use GuzzleHttpClient;
use GuzzleHttpExceptionRequestException;

// 设置API Key和Secret Key
$clientId = '[你的API Key]';
$clientSecret = '[你的Secret Key]';

// 图像文件路径
$image = './test.jpg';

// 初始化HTTP客户端
$client = new Client();

try {
    // 调用百度图像识别API
    $response = $client->post('https://aip.baidubce.com/oauth/2.0/token', [
        'form_params' => [
            'grant_type' => 'client_credentials',
            'client_id' => $clientId,
            'client_secret' => $clientSecret,
        ]
    ]);

    $result = json_decode($response->getBody(), true);
    
    // 获取Access Token
    $accessToken = $result['access_token'];

    // 构建请求URL
    $url = 'https://aip.baidubce.com/rest/2.0/ocr/v1/general_basic';

    // 构建请求参数
    $params = [
        'access_token' => $accessToken,
        'image' => base64_encode(file_get_contents($image)),
    ];

    // 调用API
    $response = $client->post($url, [
        'form_params' => $params,
    ]);

    // 解析返回结果
    $result = json_decode($response->getBody(), true);
    
    // 输出识别结果
    foreach ($result['words_result'] as $word) {
        echo $word['words'] . "
";
    }
} catch (RequestException $e) {
    echo '请求异常：' . $e->getMessage();
}
