如何使用uri与Php库一起使用Google Vision Api？

composer require google/cloud-vision

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

// 设置GCP服务帐户的JSON密钥文件路径
$jsonCredentialFile = '/path/to/your/gcp-credential-file.json';

// 初始化Vision API客户端
$client = new Google\Cloud\Vision\V1\ImageAnnotatorClient([
    'credentials' => $jsonCredentialFile,
]);

// 设置您要分析的图像URI
$imageUri = 'https://example.com/image.jpg';

// 为图像URI创建一个Image对象
$image = new Google\Cloud\Vision\V1\Image();
$image->setSource(new Google\Cloud\Vision\V1.ImageSource());
$image->getSource()->setImageUri($imageUri);

// 创建一个AnnotateImageRequest对象，并设置特征
$annotationRequest = new Google\Cloud\Vision\V1.AnnotateImageRequest();
$annotationRequest->setImage($image);
$annotationRequest->setFeatures([
    new Google\Cloud\Vision\V1.Feature([
        'type' => Google\Cloud\Vision\V1.Feature\Type::LABEL_DETECTION,
    ]),
]);

// 发送请求并获取响应
$responses = $client->batchAnnotateImages([$annotationRequest]);
$response = $responses[0];

// 处理响应
if ($response->hasError()) {
    echo "Error: " . $response->getError()->getMessage() . PHP_EOL;
} else {
    // 在这里处理检测到的标签
    $labels = $response->getLabelAnnotations();
    foreach ($labels as $label) {
        echo "Label: " . $label->getDescription() . PHP_EOL;
    }
}

// 关闭客户端
$client->close();
