python找思路_python 爬取贝壳的一些思路和方法设计(用地址找到小区名字)
1.查mysql 获取 title 或者 address
2.用title或者address参数,request.get方法 查百度地图的地址api:
http://api.map.baidu.com/place/v2/search?query=成都市青羊区青羊上街336号2栋2单元21楼2102号房屋及室内装修&tag=房地产®ion=成都
&output=json&ak=CAG9eY150GAfXkGCLPL69N5CvCpGYjm5&extensions_adcode=true&coord_type=gcj02ll&scope=2
注意里面城市和query的参数
title和查询到的结果,相似匹配度代码:

print(baidu_param)
results = search_baidu_map(baidu_param)

get_max_same_addr(results, key)
3.用相似度最高的地址去查贝壳地图找房:
当输入地址时,会自动提示,然后解析这个提示下最接近的小区
思路二:
利用百度地图和selenium选择定位小区:
