A question about QR code of WeChat public number

Now I want to make a revision to the QR code of the public, hoping to solve one of the following two questions

1: Can I scan the code to see if it is scanned by scanning or through UC or through other scanning tools? If you can, how to judge?


Question 2: If problem 1 can't be solved, solve this problem

I use a QR code decoder to decode the public QR code to get a link such as "Http://XXXXXx"

Now I want to make a page, this page inside put a

Follow the public number

Links, there may be a lot of other content, and then I put this page to generate a QR code, want to let users open the page by scanning code, click on the "attention to the public" when the public to scan the QR code like direct scanning to open the attention to the public number of the page.

But when you do, you find that clicking on that link jumps to the Google Market download page.

So the second question is to ask, in a sweep code open page, by clicking on a link to follow the public number?

First, you should make a QR code for each scan tool.
The second problem, that can only be modified or UC.

In other words, for the same two-dimensional code, there is no way to determine through the program or other methods of what tools to scan the code?

No way. Two-dimensional code is a picture, with the eyes to see also line, with the camera is also OK, scanning Tool is only after the shooting and then processed.

UserAgent this should be possible.

For QR code generation, see the latest public platform documentation

Two-dimensional code with parameters
String Eventkey_scan = Requestmap.get ("Eventkey");
System.out.println ("Two-dimensional code with parameters" +eventkey_scan);
So get the unexpectedly is 0, do not know is not so get
