/*
* access_token是变化的,有自己的周期,官方解释为:"有效期为7200秒",这就要 求我们把获得的access_token存入一个物理文件或者Application中,请求到过期后修改这些内容,需要用的时候读出来.
* 有些人可能想到了，如果过期我就在获得一个就好了,不用物理文件和Application也可以达到同样的效果,但是需要注意了微信平台对每天获得
* access_token的次数也作了限制，一个用户出发多次，如果用户多，那肯定就超出了。所以我们还是按照以上的思路实现这些功能:
* 在此之前我们已经了解了获得access_token的方法(连接),现在只需要保证它的随时更新就好了.
