PHP实现从互联网抓取图片地址然后上传到七牛云

1、实现的PHP代码

<?php
require_once __DIR__ . './autoload.php';
use Qiniu\Auth;
use Qiniu\Storage\UploadManager;
class uploadImage {
    public $access_key;
    public $secret_key;
    public $bucket;
    public function __construct()
    {
        $this->access_key = '************';
        $this->secret_key = '************';
        $this->bucket = '************';
    }
 
    public function uploadImg($imgUrl)
    {
        #读取网上图片内容
        $imageData = self::getSslPage($imgUrl);
        $auth  = new Auth($this->access_key, $this->secret_key); 
        $token = $auth->uploadToken($this->bucket);
        $key   = 'imgUrl_'.microtime(true).'.webp';
        $up    = new UploadManager();
        $mime  = 'image/webp';
        list($rest, $err) = $up->put($token, $key, $imageData, null, $mime);
        if ($err) {
            echo '<pre>';
            print_r($err);
        } else {
            echo '<pre>';
            print_r($rest);
            $domain = '上传 Bucket 外链默认';
            #获取上传到七牛云的图片url
            $uploadUrl = $domain.$rest['key'];
            echo "<img src=$uploadUrl>";   //图片显示
        }
    }
    
 
 
    public function getSslPage($url) {
           if(!empty($slika)){
             file_put_contents('vest1.webp', $slika);
            }
            $ch = curl_init();
            curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
            curl_setopt($ch, CURLOPT_HEADER, false);
            curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
            curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
            curl_setopt($ch, CURLOPT_URL, $url);
            curl_setopt($ch, CURLOPT_REFERER, $url);
            curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
            $result = curl_exec($ch);
            curl_close($ch);
            return $result;
        }
}
 
 
$upTest = new uploadImage();
$uploadImageUrl = "https://t1.g.mi.com//thumbnail//webp//w220q90//Wali//14815746cb906488408b0515c436686f4389d9ecc";
$upTest->uploadImg($uploadImageUrl);
