关于微信公众号二维码的问题

现在想对公众号的二维码做个修改，希望能解决下面两个问题中的一个

问题1：扫码时能不能判断出来是通过微信扫描还是通过UC的扫描或者是通过其他的扫码工具扫描？如果可以，怎么判断？

问题2：如果问题1没办法解决的话，求解决这个问题

我用二维码解码器把公众号二维码解码后得到一个链接如“http://XXXXXx”

现在我想做一个页面，这个页面里面放个

<a href='http://XXXXXXx'>关注微信公众号</a>

链接，可能还有其他很多内容，然后我把这个页面生成一个二维码，想让用户通过微信扫码打开页面时，点击“关注微信公众号”的时候，跟直接扫描公众号二维码一样打开关注公众号的页面。

但是做的时候发现点击那个链接后，跳转到了谷歌市场下载微信的页面。

所以第二个问题就是想问下，能不能在一个微信扫码打开的页面里，通过点击一个链接关注公众号？

回复讨论(解决方案)

第一个问题，应该针对各种扫码工具各做一个二维码。
第二个问题，那只能修改微信或UC。

也就是说，对于同一个二维码，没办法通过程序或者其他方法判断是通过什么工具扫码的了？

useragent这个应该可以

关于二维码生成，请查看最新的微信公众平台文档

//带参的二维码
String eventKey_scan = requestMap.get("EventKey");
System.out.println("带参的二维码"+eventKey_scan);
这样获取的竟然是0，不知道是不是这样获取
