百度API得到XX地区所有YY的经纬度坐标
好久没写博客了，贴一个很久以前为大姐的毕业论文而写一个小程序，还比较方便，比如说，我要得到上海市所有沃尔玛的经纬度坐标，并且将信息汇总到Excel中，操作如下：
1.将后文的代码保存到记事本（.txt），然后呢再把这个txt文档的后缀改为.htm
2.双击就可以啦（如果你的默认浏览器是IE，不是的话，选择打开方式为IE浏览器，我这个只支持IE浏览器），IE会请求允许之类的，总之都允许就好了
3. 更改保存路径，记得文件名的后缀一定是.xls/.xlsx。
4. 然后，单击开始查询
5.单击写入Excel，如下图
说明：
1.前两个功能大家一实便知，最后一个是坐标转换，天国所有的坐标都不允许使用真实坐标，要使用火星坐标，即GCJ-02，like 谷歌地图，而百度地图的坐标体系又自成一体，所以这个功能就是把百度坐标转成火星坐标。
2. 如果是想查询北京市的沃尔玛怎么办呢？天才的观众，你们一定猜得出来只要改改代码就好啦，相信你们一定知道改哪里。
3. 为方便广大群众，可以一次性查询很多关键词，Excel会自动添加新页
4. 如果你在全国范围内查询沃尔玛，会得到上海地区的沃尔玛数量不止74！！！！难倒我错了？程序没有错，当你单击上海市的沃尔玛，然后一个一个数的时候你会发现只有74个，不知道百度怎么回事！！呃，一数不知道，一数吓一跳，一you般来说，我的数目和你实际输出来的是一样的，可是这次居然我的数据还多了4个，特意核对了一下，妈蛋，有几个是重复的，比如田林路的那个沃尔玛，居然有几个不一样的地名，幸好我经常去那个沃尔玛，看来是不够严谨。很多 C多多(五角场沃尔玛店)、欧味多(祁连山沃尔玛店) 之类的地方，好吧，百度并没有按类别分类，也就是说查出来的可能不是超市，只是名字里面有沃尔玛，这就解释的通了，理论上是可以通过距离远近去掉一些，好吧，这个我也懒得处理了。换成沃尔玛超市之后会好一点，不纠结了，反正对于快递之类的是正确的，因为不会有 XX（顺丰快递店），对于沃尔玛之类的里面还包含了其它东西的就自己按照公司名检查一遍吧。
5. 算是第一次接触百度API，所以很多功能是实现了，但是方法很笨，比如自动翻页，因为我找不到对于的函数，见谅，说完了，
