利用PHP对接Midjourney，打造高效、智能的AI绘画工具

<?php
// 设置API密钥
$apiKey = "YOUR_API_KEY";

// 定义绘画函数
function paint($imagePath) {
    global $apiKey;

    // 定义API请求URL
    $url = "https://api.midjourney.com/paint";

    // 设置请求头
    $headers = [
        "Content-Type: multipart/form-data",
    ];

    // 设置请求体
    $fields = [
        "image" => new CURLFile($imagePath, "image/png"),
        "model" => "default",
    ];

    // 发起API请求
    $curl = curl_init();
    curl_setopt($curl, CURLOPT_URL, $url);
    curl_setopt($curl, CURLOPT_POST, true);
    curl_setopt($curl, CURLOPT_POSTFIELDS, $fields);
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($curl, CURLOPT_HTTPHEADER, $headers);
    curl_setopt($curl, CURLOPT_USERPWD, $apiKey);
    $response = curl_exec($curl);
    curl_close($curl);

    // 处理响应结果
    $result = json_decode($response, true);
    if ($result && isset($result['success']) && $result['success']) {
        return $result['result'];
    } else {
        return null;
    }
}

// 示例用法
$imagePath = "path/to/your/image.png";
$result = paint($imagePath);
if ($result) {
    // 处理生成的绘画结果
    // TODO: 在此处添加你的代码
} else {
    echo "Failed to generate painting.";
}
