PHP调用Muse Ember教程：用cURL发送Responses请求并读取文本结果-php教程-PHP中文网

muse ember在meta model api中的标识为muse-ember-1.0，支持responses接口。php项目可通过curl提交json请求。以下示例需要有效的meta model api权限，示例中的环境变量应由服务器提供，账户和地区可用范围按平台实际规则核对。

准备密钥与运行环境

确认PHP已启用cURL，并把Meta Model API密钥放在服务器环境变量MODEL_API_KEY中。不要把密钥写进前端页面、可公开下载的PHP文件或日志。

发送一个边界明确的分类任务

<?php $key = getenv('MODEL_API_KEY');
if (!$key) { throw new RuntimeException('缺少MODEL_API_KEY'); }
$payload = [
    'model' => 'muse-ember-1.0',
    'input' => '将这条工单归为billing、bug或feature：本月账单被重复扣款。只返回类别。',
];
$ch = curl_init('https://api.meta.ai/v1/responses');
curl_setopt_array($ch, [
    CURLOPT_POST => true,
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_TIMEOUT => 90,
    CURLOPT_HTTPHEADER => [
        'Authorization: Bearer ' . $key,
        'Content-Type: application/json',
    ],
    CURLOPT_POSTFIELDS => json_encode($payload, JSON_UNESCAPED_UNICODE | JSON_THROW_ON_ERROR),
]);
$raw = curl_exec($ch);
$status = curl_getinfo($ch, CURLINFO_HTTP_CODE);
$error = curl_error($ch);
curl_close($ch);
if ($raw === false) { throw new RuntimeException($error); }
if ($status = 300) {
    throw new RuntimeException('API请求未成功，HTTP状态：' . $status);
}
$data = json_decode($raw, true, 512, JSON_THROW_ON_ERROR);
if (($data['status'] ?? '') !== 'completed') {
    throw new RuntimeException('响应未完成，请核对status与error');
}
$text = '';
foreach ($data['output'] ?? [] as $item) {
    foreach ($item['content'] ?? [] as $part) {
        if (($part['type'] ?? '') === 'output_text') {
            $text .= $part['text'] ?? '';
        }
    }
}
if ($text === '') { throw new RuntimeException('未返回文本结果'); }
echo $text;
