[英]Access JSON from wp_remote_get in Wordpress
I'm trying to access the json that's returned from this Google books API request using wp_remote_get but its not outputting the data. 我正在尝试使用wp_remote_get访问从此Google图书API请求返回的json,但它不输出数据。 Can anyone tell me what the problem is?
谁能告诉我这是什么问题?
$request = wp_remote_get('https://books.google.com/books?bibkeys=9780001955073%2C%209780001982116%2C%209780001981768&jscmd=viewapi&callback=listisbns');
$body = wp_remote_retrieve_body( $request );
$data = json_decode( $body );
foreach( $data as $book ) {
echo $book->info_url;
}
It would be ok if you were using JavaScript via the callback function listisbns
, to use the returned result in PHP you gotta clean up the returned string: 如果您通过回调函数
listisbns
使用JavaScript,在PHP中使用返回的结果,则必须清理返回的字符串:
$body = wp_remote_retrieve_body( $request );
# clean start removing "listisbns("
$body = str_replace( 'listisbns(', '', $body );
# clean end removing last two characters: ");"
$body = substr( $body, 0, strlen($body) - 2 );
# data ok to proceed
$data = json_decode( $body );
