通过PHP cUrl创建DHL船标签不起作用

Question

我想通过DHL创建货运标签（以pdf格式）。 因此，我创建了所需的xml格式，并通过PHP cUrl发布了相同的格式。

$message_ref = '';
for ($i=0; $i< 30; $i++)
{
    $message_ref .= rand(0, 9);

}   
$message_time = date("Y-m-d") . "T" . date("H:i:sP");

以下是XML的代码 ：

<?xml version="1.0" encoding="ISO-8859-1"?>
<req:ShipmentValidateRequest xmlns:req="http://www.dhl.com" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.dhl.com ship-val-req.xsd">

下面是cUrl代码：

$url = "https://xmlpi-ea.dhl.com/XMLShippingServlet";

修改 -

$ch = curl_init($url);
            curl_setopt($ch, CURLOPT_MUTE, 1);
            curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
            curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
            curl_setopt($ch, CURLOPT_POST, 1);
            curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: text/xml'));
            curl_setopt($ch, CURLOPT_POSTFIELDS, "$query");
            curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
            $output = curl_exec($ch);
            curl_close($ch);
#print_r($output);

preg_match("/<OutputImage>(.*?)<\/OutputImage>/", $output, $matches);
   $image = base64_decode($matches[1]);

<img src="data:image/gif;base64,<?=$image?>">

现在，我看到图像在浏览器中显示垃圾字符。 我在$ image之前附加了“ data：image / gif; base64”，但仍显示垃圾字符。 有人可以帮我显示图像吗？

最后，我通过添加代码解决了它：

header("Content-type:application/pdf");
header("Content-Disposition:inline;filename=label_123demo.pdf");
echo $image;
