来自Web应用程序的条形码扫描程序不返回任何内容

Question

When clicking on the link on an Android device we can choose to open it in the Barcode Scanner app, but when we scan a barcode it doesn't return anything.

This is our link:

<a href="zxing://scan/?ret=<?php echo urlencode("http://172.20.200/projekt/matjakt/Frontend/search.php?s={CODE}"); ?>&SCAN_FORMATS=UPC_A,EAN_13" class="scan">

Also when clicking the link on an iPhone, the scanner app opens but just displays a white screen, so we can't scan anything.

Any ideas on what's wrong?

Answer 1

Your return url is invalid. http://172.20.200 does not make any sense. Either use a domain name or some valid IP. Your IP has three parts. But a valid IP should have four parts.
