随着滴滴打车的火起，现在越来越多有点实力的公司，都想做个类似滴滴打车的应用，于是就开始招程序，或者 买源码，撸起袖子干起来。下面深圳沃龙软件开发公司将会在本文中会为大家介绍一下，【司机上报位置解决方案】和【等待费用计算方案】！
如果你想开发类似 滴滴打车或购买源码，请联系我们，深圳沃龙软件开发公司，网址：www.wooolong.com QQ:82516886
1、上报位置：
1.1 APP每间隔20秒上报一次位置，并本地缓存一条，包含数据【司机ID，经度、纬度、状态(0:下班；1:上班；2：载客中)、上报时间】
1.2 上报之前和上一次上报的一条数据（缓存在APP本地）通过经度，纬度比较，大于2米，则上报；小于2米，则不上报。上报的时候，本地也缓存一条。
1.3 服务器端将APP端上报的数据，根据司机ID，增加或根据司机ID修改到Redis。
注意：上报数据只基于 司机上班和载客的过程中才上报！
2、计算等候时间：
为了更好的体验服务，所以要把计算费用这块，放在本地去解决
2.1 APP每间隔20秒获取一下当前位置，并缓存到APP本地,根据 经度，纬度比较：
2.1.1 大于2米，则比较上一次上报的记录时间和本次获取的时间，如果大于3分钟（等候红绿灯或者堵车超过3分钟才计等待费），
则本次上报时间-上次时报时间 = 多少分钟 *每分钟等候费用 = 应付价钱 ，保存到本地缓存中，后面如果再等候了，再根据2.1.1计算出来的等候费用+上一次等候费用，依次类推即可！
2.1.2 小于2米，则不上报。
本次就先介绍到这里，欢迎继续关注，下期将继续介绍滴滴打车实现思路剖析！

With my career in the political arena at least temporarily done as a result of my actions. They say whatever you put ahead of your recovery will be the second thing you lose. I can't agree enough.
