-------------------------------------------------- ----------------------------------

1) API application

Aibang provides query Interface API, you need to apply for Key http://www.aibang.com

The number of queries is limited, 2013-12-4, up to 1000 times/10 times per day/minute

2) API call

After calling the API to obtain the data, you can output it in your own format

/*

var_dump($a);

3) Effect display

4) Accurate query

In bus query, the required input is the bus/subway station name

If you don’t know the exact bus station name, you often won’t get the result.

On the web page, the system can prompt you to select the accurate bus stop,

However, it is inconvenient to do this on WeChat

The improvement plan is as follows:

Aibang has a bus station query API

Find user input information through this API Nearby stations and take out the first bus transfer station

In this way, the probability of successful bus transfer search is increased.
