最近看了一篇博文是說微信公眾平臺搭建，于是心血來潮自己也嘗試了一下。

1.不用多講了，申請微信公眾號，對于個人來說，只能申請訂閱號。

可以看這個鏈接的文章，http://jingyan.baidu.com/article/414eccf6011ff06b431f0aec.html

2.采用的是Sina App Engine來脫管服務，就要申請sae開發者權限。

再看這個鏈接http://jingyan.baidu.com/article/4f7d57129a60531a20192796.html

3.在sae上新建一個應用

我選擇的php，PHP幾乎免費。java應用的話，有點小貴了。

雖然沒有學過PHP，摸著石頭過河吧。

將php代碼上傳后，就有一個可調試的url了，PHP代碼后面上。

4.再在微信公眾平臺中的開發者中心（這個要經過一段時間的審核），填入一下內容即可

5.然后就是對接數據了，為了測試，我對接的是圖靈機器人的數據、12306和百度地圖API

12306是為了查余票和車次，百度地圖API是為了查天氣預報、圖靈機器人見鏈接：http://www.tuling123.com/openapi/

php代碼如下，本人不是搞PHP的，因此只能在網上拷貝了，如有復制，純屬巧合。
