输出标准的Base64恩codeD流成PDF格式（PHP） [英] Output a standard Base64 Encoded stream into PDF format (PHP)

问题描述

我现在用的是英国皇家邮政送货API生成打印的PDF标签，我的PHP SoapClient的返回如下所示的有效响应（只显示整个响应最初的反应是巨大的）。

I am using the Royal Mail Shipping API to generate printed PDF labels, my PHP SoapClient returns a valid response shown below (only shown the initial response as the whole response is huge).

任何人都可以建议转换这一带的Base64 codeD PDF标签正确的最好方法，所以我可以实际下载这个浏览器。下面我的code下载PDF文件，但是当我尝试打开该文件大小始终是57KB，我将返回在Acrobat Reader下面的消息

Can anyone suggest the best method to 'convert' this Base64 encoded PDF label correctly so I can physically download this to the browser. My code below downloads the PDF file but when I attempt to open this the filesize is always 57kb and I returns the following message in Acrobat Reader

"There was an error opening this document. The file is damaged and could not be repaired."

我的code是如下：

My code is as follows:

$rm = new RoyalMailLabelRequest();
// provide shipment number, order tracking id, output format (e.g PDF/PNG)
$response = $rm->PrintLabel('TTT000358756GB', '276831601444829801', 'PDF');

header('Content-type: application/pdf');
header('Content-Disposition: attachment; filename="doc-'.$document.'.pdf"');
$data = base64_decode($response);
file_put_contents('pdf/label.pdf', $data);

更新

当我尝试回声脱codeD响应我得到以下...不知道是什么这一个发生..奇怪的。

UPDATE

When I try to echo the decoded response I get the following... not sure what is happening with this one.. odd.

$response = $rm->PrintLabel('TTT000358756GB', '276831601444829801', 'PDF');
$data = base64_decode($response);
echo $data;exit;

作为base64_de codeD之后

中回显$数据响应

Echo'd $data response after being base64_decoded

我还补充说，由我的code回到这里引擎收录完整base64_en code响应，如果它可以帮助任何人

推荐答案

排序 - 是一个很漫长的一天。

Sorted - been a very long day.

我并不需要取消code到底反应，使下面的工作（希望它可以帮助别人做的API集成）

I didn't need to decode the response in the end so the following will work (hopefully it helps someone else doing the API integration)

function PrintLabelRequest($shipmentNumber, $transactionId)
{
   $rm = new RoyalMailLabelRequest();

   // function from library returns a response using SOAP
   $response = $rm->PrintLabel($shipmentNumber, $transactionId);

   // name the file & saved this label as a PDF in the following folder
   $filename = 'printedlabel-' . $shipmentNumber;
   file_put_contents(dirname(__FILE__) . '/labels/'. $filename .'.pdf', $response);
}
