Question

我正在尝试使用wp_remote_get访问从此Google图书API请求返回的json，但它没有输出数据。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;
}

如果你通过回调函数listisbns使用JavaScript就可以了，要在PHP中使用返回的结果，你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 );

从Wordpress中的wp_remote_get访问JSON
