【背景】
折腾：
期间，先要去搞懂并申请ACCESS_TOKEN。
【折腾过程】
1.参考官网文档：
已经注意到，对于获取ACCESS_TOKEN，官网也是有限定的：
接口 | 每日限额 |
获取access_token | 2000 |
2.然后去写代码，获取ACCESS_TOKEN。
其中所需要的值：
AppID和AppSecret
是可以在微信的开发者中心中看到的：
3.然后就是去写代码去了。
期间，需要利用我自己之前的功能CrifanLib.php，然后继续丰富内容，便于后续调用。
其中遇到：
4.然后接着去利用crifanLib.php中的getUrlRespHtml去实现https访问。
然后为了写的URL更加通用，所以再去研究：
5.然后接着为了优化log函数，希望支持类似于sprintf的动态参数：
【已解决】将Log函数的参数改变为类似于sprintf的动态参数
【总结】
然后再去调用自己的库函数crifanLib.php中的getUrlRespHtml，然后就可以正常获得access_token了：
对应代码是：
crifanLib.php
