我建议暂时注释掉所有的cflocations，看看你的行为是否相同。这可能是因为您的登录过程没有在您的cflocation开始之前完成。

I would suggest commenting out all of your cflocations temporarily and seeing if your behaviour is the same. It could be that your login process doesn't finish before your cflocation starts.

或者，可能是您的网页首次正确提交，然后第二次点击else子句。

Or, it could be that your page submits to itself correctly the first time, and then the second time hits the else clause.

您的代码中没有任何内容对我显然是错误的。

There is nothing in your code that is obviously wrong to me.
