使用json_encode和PHP处理base64编码图像

Question

我的PHP类返回一个小的base64编码图像,链接这个:

class Service
{

  function getLogo()
  {
    $image = "iVBORw0KGgoAAAANSUhEUgAAABAAAAAQCAYAAAAf8/9hAAAAAXNSR0IArs4c
             QAAAARnQU1BAACxjwv8YQUAAAAgY0hSTQAAeiYAAICEAAD6AAAAgOgAAHUwA";

    return 'data:image/png;base64,' . $image;
  }

}

使用返回图像json_encode将\n在每行之后添加$image:

$service = new Service();
$response = array('name' => $service->getName(), 'logo' => $service->getLogo());
header('Content-type: application/json');
echo json_encode($response);

如何正确处理？

Answer 1

你通过将它分成两行来破坏你的base64数据.它应该是

function getLogo() {
    $image = "iVBORw0KGgoAAAANSUhEUgAAABAAAAAQCAYAAAAf8/9hAAAAAXNSR0IArs4cQAAAARnQU1BAACxjwv8YQUAAAAgY0hSTQAAeiYAAICEAAD6AAAAgOgAAHUwA";

    return 'data:image/png;base64,' . $image;
}

没有换行符.
