微信开发之公交换乘功能代码详解
公交查询中,要求输入的是公交/地铁的站名 如果不知道准确的站名,往往得不到结果, 在网页上,系统可以通过提示选择准确的公交站点来完成,

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
