QR 码扫描不正确，但测试显示它包含正确的 URL

Question

我有一个 QR 码，其中编码了以下 url：

https://www.songbookdb.com/books/SHAYLA

然而扫描二维码阅读器会出现

https://www.songbookdb.com?b=GFPTX

我查看了 https://zxing.org/w/decode.jspx 处的二维码图像，它告诉我嵌入的 URL 是

https://www.songbookdb.com/books/SHAYLA

我想弄清楚为什么我会在

https://www.songbookdb.com?b=GFPTX

...我想也许我在服务器端做了一些古怪的事情，但我很确定 URL 击中服务器是

https://www.songbookdb.com?b=GFPTX

你们扫描了什么？

感谢观看。

Answer 1

I have a QR code that has the following url encoded into it:

https://www.songbookdb.com/books/SHAYLA

你是如何用 zxing.org 检查的？ I get this:

Raw text    www.songbookdb.com?b=GFPTX
Raw bytes   41 a7 77 77 72 e7 36 f6   e6 76 26 f6 f6 b6 46 22 e6 36 f6 d3 f6 23 d4 74   65 05 45 80 ec 11 ec 11 ec 11 
Barcode format  QR_CODE
Parsed Result Type  URI
Parsed Result   http://www.songbookdb.com?b=GFPTX

这个二维码是怎么生成的？您的生成器似乎已经遵循了您从服务器获得的 301 重定向：
