使用php进行javascript google ocr文本检测

<?php
// 定义Google Cloud Vision API的请求URL
$url = 'https://vision.googleapis.com/v1/images:annotate?key=YOUR_API_KEY';

// 准备请求数据
$imageData = base64_encode(file_get_contents('path/to/image.jpg'));
$data = array(
    'requests' => array(
        array(
            'image' => array(
                'content' => $imageData
            ),
            'features' => array(
                array(
                    'type' => 'DOCUMENT_TEXT_DETECTION'
                )
            )
        )
    )
);

// 发送POST请求到Google Cloud Vision API
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($data));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($ch);
curl_close($ch);

// 解析API的响应
$result = json_decode($response, true);

// 提取识别到的文本
$textAnnotations = $result['responses'][0]['textAnnotations'];
$detectedText = $textAnnotations[0]['description'];

// 输出识别到的文本
echo $detectedText;
?>
