自动定位需要特定的api，比如百度等。

在需要的地方调用第三方提供的api调用定位相关代码就好。
说一下个人的大致思路吧，移动端可以通过调用接口去获得当前位置的经纬度，然后把经纬度信息放入数据库，之后pc端的程序调用数据库里的经纬度信息就可以了。
(3,4,N)
上北下南左西又东
顺时针排序：北东南西
北1 东2 南3 西4
（3,4,1）
左转1+1=2东
右转1-1=01,则0=4西
后转1+2=3南
可以把朝向问题看成类似约瑟夫的问题。
用数组记录当前坐标X Y 及朝向。用1,2,3,4代表北东南西
左转后，（3,4,2）
往前一步，
当朝向不同的时候，有对应的向前向后是改变哪个坐标值，
写四个朝向时候的坐标的算法
然后调用，传入2，则调用case=2时的动作，如果向前则~~~向后则~~~~再命令转向则（调用处理方向改变的函数）~~~~
最后输出（，，），对最后一个兑换成“东南西北”输出就行了
