Python利用Redis计算经纬度距离案例

pip install redis

import redis
class RedisCtrl(object):
    @staticmethod
    def connect(config):
        pool = redis.ConnectionPool(
            host=config['host'],
            db=config['db'],
            port=config['port'],
            password=config['password'],
        )
        return redis.StrictRedis(connection_pool=pool)

rd = RedisCtrl.connect({
    "db": 1,
    "port": "6379",
    "password": "password",
    "host": "",
})

rd.geoadd(name="集合名称", values=["经度", "维度", "地址名称"])

result = rd.geopos("集合名称", "地址名称1", "地址名称2")
print(result)  # [(地址1的经度, 地址1的维度), (地址2的经度, 地址2的维度)]

result = rd.geopos("集合名称", "错误名称1", "错误名称2")
print(result)  # [None, None]

rd.geodist("集合名称", "地址名称1", "地址名称2", unit="km")

result = rd.georadius(name="集合名称", longitude="经度", latitude="维度", radius="半径距离", unit="半径单位",
                     sort='ASC', count=10, withdist=True, withcoord=True)
print(result)    # [[b'地址名称', 距离, (经度, 维度)], [b'shanghai', 0.1774, (121.4813420176506, 31.235159732038248)]]
