PHP如何对接百度自然语言情感分析接口？

composer require baidu-aip/php-sdk

require_once 'vendor/autoload.php';

use AipNlpAipNlp;

// 在百度AI开发者平台创建应用后获取到的API Key和Secret Key
const APP_ID = 'your_app_id';
const API_KEY = 'your_api_key';
const SECRET_KEY = 'your_secret_key';

$client = new AipNlp(APP_ID, API_KEY, SECRET_KEY);

function analyzeSentiment($text) {
    global $client;

    $result = $client->sentimentClassify($text);

    if(isset($result['items'])) {
        // 获取情感分析结果
        $sentiments = $result['items'][0]['sentiment'];

        switch($sentiments) {
            case 0:
                $sentiment = "负面";
                break;
            case 1:
                $sentiment = "中性";
                break;
            case 2:
                $sentiment = "正面";
                break;
            default:
                $sentiment = "未知";
                break;
        }

        return $sentiment;
    }

    return "未知";
}

$text = "今天天气真好！";

$sentiment = analyzeSentiment($text);

echo "文本：".$text."<br/>";
echo "情感分析结果：".$sentiment."<br/>";

文本：今天天气真好！
情感分析结果：正面
