我是靠谱客的博主害怕小甜瓜，这篇文章主要介绍微信开发之公交换乘功能代码详解，现在分享给大家，希望可以做个参考。

1）API申请
2）API调用
3）[b]效果展示[/b]
4）精准查询
--------------------------------------------------------------------------
1）API申请

爱帮提供查询接口API，需要申请Key www.aibang.com

查询数量有限制，2013-12-4 最多 1000次/每天 10次/分钟

返回json数据

提供数据说明

提供demo文件

2）API调用

调用API取得数据后，按自己的格式输出即可
