PHP如何對接百度語音情緒辨識介面？

<?php
// 定义接口的URL
$url = 'https://aidemo.baidu.com/api/emotion/v1/audio';

// 定义请求头
$headers = array(
    'Content-Type: application/json;charset=UTF-8',
);

// 定义请求参数
$data = array(
    'format' => 'pcm',
    'token' => 'YOUR_TOKEN',
    'cuid' => 'YOUR_CUID',
    'rate' => 16000,
    'channel' => 1,
    'speech' => base64_encode(file_get_contents('YOUR_AUDIO_FILE')),
);

// 发送HTTP POST请求
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($data));
$result = curl_exec($ch);
curl_close($ch);

// 处理返回结果
if ($result) {
    $result = json_decode($result, true);
    if ($result['err_no'] == 0) {
        // 请求成功
        $emotion = $result['result']['emotion'];
        echo "情感识别结果：$emotion";
    } else {
        // 请求失败
        $err_msg = $result['err_msg'];
        echo "请求失败：$err_msg";
    }
} else {
    echo "请求失败";
}
?>
