这里会有一个问题，对于其他用户来说，不传isMp时会自动网页扫码登录，向下兼容有问题。并且我们这个主要是作为手机端使用，建议使用一个相反的条件来针对网页扫码登录做单独判断

这里传与不传的话默认不会去到网页扫码登录，需要同时传进snsapi_login才会去到扫码登录，这里是我的注释解释的有问题。。= =。。isMp只是利用开放平台在公众平台上作授权而已。。

了解，刚刚查了下，公众平台没有snsapi_login这个选项，那这里是不是可以直接通过snsapi_login这一个值来判断就可以了，还需要isMp这个参数吗？

是的，公众平台是没有snsapi_login这个选项的，snsapi_login这个选项是开放平台中的扫码登录的选项，isMp这个选项是必须的，因为针对开放平台的话 扫码与授权 所请求的url不一致。isMp仅仅是针对于使用开放平台在公众号内做授权（个人订阅号或未认证订阅号没有接口权限），如果本身的的公众号有接口权限的话就不需要了。
