Implementation code for downloading remote images to local using Http class that comes with ThinkPHP_PHP Tutorial

The Http class is under the directory ThinkPHP/Lib/ORG/Net. Next let's see how it is called.

Copy code The code is as follows:

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'];
}
}
?>

here I first determine whether there is the image information in the database. If not, I call Amazon's webservice to obtain the image address remotely, and then use

to copy the code The code is as follows:

Http::curl_download($remoteUrl['ImageURL'], "./".$localUrl);

The first parameter of the curl_download method is the remote image address , the second parameter is the address saved to the local area.
OK, it’s that simple~~
