Use the Http class that comes with ThinkPHP to download remote images to a local implementation code _ PHP Tutorial

Use the Http class that comes with ThinkPHP to download the remote image to the local implementation code. The Http class is under the ThinkPHPLibORGNet directory. Next, let's take a look at how to call it. Copy the code as follows :? Phpimport (Com. Buyback. QueryAmazon); import (ORG. Net. Http); classIm Http class is under the ThinkPHP/Lib/ORG/Net directory. Next, let's take a look at how to call it.

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 the image information is in the database. if not, I call amazon's webservice to remotely obtain the image address and then use

The code is as follows:

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

The first parameter of the curl_download method is the remote image address, and the second parameter is the local address.
OK, that's simple ~~
