我无法使用PHP找到解决方案。基本上,当用户点击“下载PDF”链接时,它将调用PHP函数,该函数接受一个字节数组并将其解析为PDF。我不知道如何去做。任何帮助都会很棒!
编辑: 我得到像这样的“字节数组”:
<?php
$userPDF = $_POST['username'];
$passPDF = $_POST['password'];
$idPDF = 'MO-N007175A';
//PDF Function
$data = array("id" => $idPDF, "username" => $userPDF, "password" => $passPDF);
$data_string = json_encode($data);
$ch = curl_init('http://*****.com/****/v1/DealPdf');
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_VERBOSE, 1 );
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
'Content-Type: application/json')
);
$result = curl_exec($ch);
var_dump($result);
?>
“$ result”应该是字节数组,如下所示:
string(1053240) "[37,80,68,70,45,49,46,54,10,37,211,244,204,225,10,49,32,48,32,111,98
...等。 基本上我需要采取什么即时取回并将其保存为PDF(或任何通用文件)。

您可以尝试这样的事情:
// suppose that the response is a JSON array (look like it)
$bytes = json_decode($results);
$fp = fopen('myfile.pdf', 'wb+');
while(!empty($bytes)) {
$byte1 = array_shift($bytes);
$byte2 = array_shift($bytes);
if(!$byte2) {
$byte2 = 0;
}
fwrite($fp, pack("n*", ($byte1 << 8) + $byte2); // big endian byte order ?
}
fclose($fp);

GiDo的答案会起作用,但大文件将花费很长时间。我建议您执行以下操作:
$bytes = json_decode($results);
$bytesStr = pack('C*', ...$bytes);
file_put_contents('myfile.pdf', $bytesStr);
