使用ThinkPHP自带的Http类下载远程图片到本地的实现代码

<?php
import("com.buyback.queryamazon");
import("org.net.http");
class image {
public static function getimage($isbn) {
$bookinformmodel = d("bookinform");
$result = $bookinformmodel->where("isbn='$isbn'")->select();
if($result[0]['image'] == ""){
$data['inform_id'] = $result[0]['inform_id'];
$remoteurl = queryamazon::getimage($isbn);
if(!empty($remoteurl['imageurl'])){
$localurl = "public/bookcover/".$isbn.".jpg";
http::curl_download($remoteurl['imageurl'], "./".$localurl);
}else{
$localurl = "public/bookcover/unknownbook.png";
}
$data['image'] = $localurl;
$bookinformmodel->save($data);
return $localurl;
}
return $result[0]['image'];
}
}
?>

http::curl_download($remoteurl['imageurl'], "./".$localurl);
