Answer 1

我已经解决了这个问题。实际上它是base64编码。我使用base64_decode解码后能够生成pdf。

Answer 2

header('Content-type: application/pdf');
header('Content-Disposition: attachment; filename="service.pdf"');
echo base64_decode($byte_string);

只为我工作。

Answer 3

你可以用标题回复它。

header('Content-type: application/pdf');
header('Content-Disposition: attachment; filename="service.pdf"');
echo $byte_string;

header

但我无法将提供的字符串读作PDF格式。
