Question about QR code of WeChat official account

I want to modify the QR code of the public account to solve one of the following two problems:

Question 1: when scanning the code, can I determine whether to scan the code through UC or other scanning tools? If so, how can we determine?


Problem 2: If Problem 1 cannot be solved, solve the problem.

I decoded the public QR code using the QR code decoder and got a link, such as "http: // XXXXXx"

Now I want to create a page, which contains

Follow public account

Link, there may be a lot of other content, and then I will generate a QR code for this page, to ask the user to scan the code to open the page, click "follow public account, like scanning the QR code of a public account directly, open the page that follows the public account.

However, when I found that I clicked the link and jumped to the Google market download page.

So the second question is: can I follow the public account by clicking a link on a page opened by scanning the QR code?

The first problem is to create a QR code for each scanning tool.
The second problem is that it can only be modified or UC.

That is to say, for the same QR code, there is no way to use programs or other methods to determine which tool is used to scan the code?

No way. A qr code is an image that can be viewed with your eyes and captured with a camera. the scanning tool only processes the image after it is taken.

Useragent.

For more information about QR code generation, see the latest public platform documentation.

// QR code with parameters
String eventKey_scan = requestMap. get ("EventKey ");
System. out. println ("two-dimensional code with parameters" + eventKey_scan );
The result is 0. I don't know if it is.
