如何在php中使用curl发布图像

<?php
// 图像文件路径
$imagePath = '/path/to/image.jpg';

// 目标URL
$targetUrl = 'http://example.com/upload.php';

// 初始化cURL
$curl = curl_init();

// 设置cURL选项
curl_setopt($curl, CURLOPT_URL, $targetUrl);
curl_setopt($curl, CURLOPT_POST, true);
curl_setopt($curl, CURLOPT_POSTFIELDS, [
    'image' => new CURLFile($imagePath)
]);

// 执行cURL请求
$response = curl_exec($curl);

// 检查请求是否成功
if ($response === false) {
    echo 'cURL Error: ' . curl_error($curl);
} else {
    echo 'Image uploaded successfully!';
}

// 关闭cURL资源
curl_close($curl);
?>
