利用PHP与七牛云存储接口实现图片的智能识别与标签分类的方法

<?php

require 'autoload.php'; // 导入七牛云存储的PHP SDK

use QiniuStorageUploadManager;
use QiniuAuth;

// 需要填写七牛云存储的AccessKey和SecretKey
$accessKey = 'your-access-key';
$secretKey = 'your-secret-key';

// 初始化Auth对象
$auth = new Auth($accessKey, $secretKey);

// 需要上传的图片文件路径
$filePath = './path/to/your/image.jpg';

// 生成上传Token
$token = $auth->uploadToken('your-bucket-name');

// 初始化UploadManager对象
$uploadMgr = new UploadManager();

// 上传图片到七牛云存储
list($ret, $err) = $uploadMgr->putFile($token, null, $filePath);

if ($err !== null) {
    // 上传图片失败
    echo 'Upload failed:', $err->message();
} else {
    // 上传图片成功
    $imageKey = $ret['key'];
    
    // 调用七牛云存储的图像识别API，获取图片的标签分类
    $url = 'http://ai.qiniuapi.com/v1/ai/predict';
    $data = ['url' => 'your-image-url', 'model' => 'img_tag'];

    $headers = [
        'Content-Type:application/json',
        'Authorization:Qiniu ' . $auth->signRequest($url, null, 'POST', $headers, json_encode($data))
    ];

    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_POST, 1);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
    curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($data));

    $response = curl_exec($ch);
    curl_close($ch);

    // 解析返回的结果
    $result = json_decode($response, true);

    // 获取图片的标签分类
    $labels = isset($result['result']) ? $result['result'] : [];

    // 输出图片的标签分类
    echo 'Image labels:', implode(', ', $labels);
}
