Question

I did qr code with Zxing, Right now I can read data but what I want is :

Example: Be able read type of QR Code is wifi, VCard, Calendar, url, etc... if detect QR Code is wifi so I be able code to change wifi setting key,

因此,我如何知道从QR代码读取的数据是不可靠的?

Answer 1

QR Code itself does not specify any types. Its plain text. It can be an HTTP URL or a custom URL. (e.g. it should have "type://wifi" inside it. You can then use it to see what the type is). But off-the-shelf, there is no such thing. You have to know who is creating the QR Codes and what is he storing in them.
