python +高德地图API调用

第一步：申请key
第二步：发起http/https请求
第三步：接收请求返回的数据（JSON或XML格式）

url：https://restapi.amap.com/v3/geocode/geo?parameters
https://restapi.amap.com/v3/geocode/geo?address=北京市朝阳区阜通东大街6号&output=XML&key=<用户的key>

返回的参数通过请求参数 output 指定，默认为 JSON 形式。返回的省市区信息为简要地址信息

def address(address):
    url="http://restapi.amap.com/v3/geocode/geo?key=%s&address=%s"%('你的key',address)
    data=requests.get(url)
    contest=data.json()
    #返回经度和纬度
    contest=contest['geocodes'][0]['location']
    return contest

批量地址编码

def geocode_batch(address_list):
    location_list = []

    num_reqs = len(address_list) // 20
    for index in range(num_reqs):
        sl = slice(index * 20, (index + 1) * 20)#每20个进行解析
        address_picked = address_list[sl]  
        address = '|'.join(address_picked)  # 用“|”拼接地址
        url = 'http://restapi.amap.com/v3/geocode/geo'
        params = {
            'address':address, 
            'key':'你的key', 
            'batch':True  # 要传batch参数，False为单点查询
        }

        try:
            res = requests.get(url, params, timeout=10)
            for add, geo in zip(address_picked, res.json()['geocodes']):
                if geo['location']:  # 当地址错误时，该地址的location为空
                    location = map(float, geo['location'].split(','))
                else:
                    print('address:{} can't be geocoded.'.format(add))
                    location = [None] * 2  # 异常值用None代替
                location_list.append(location)
        except Exception as e:
            print(e)
            location_list += [[None, None]] * len(address_picked)

    return location_list
