python +高德地图API调用

1.地理/逆地理编码

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) // 20for 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

不同写法：

import requests# 执行一次高德地图地理逆编码的查询
# 输入值：coordList -> 经纬度的序列,currentKey -> 当前使用的Key
# 返回值：resultList -> 查询成功，返回结果地址的序列
#        -1 -> 执行当前查询时Key的配额用完了
#        -2 -> 执行当前查询出错
def geocode(locationlist):res=[]for add in locationlist:url = 'https://restapi.amap.com/v3/geocode/regeo?key=你的key&location='+add#     print(url)response = requests.get(url=url)answer = json.loads(response.text)adress = answer['regeocode']['formatted_address']
#     adress = answer['regeocode']['addressComponent']['province'] + \
#              answer['regeocode']['addressComponent']['city'] + \
#              answer['regeocode']['addressComponent']['district']+\
#              answer['regeocode']['addressComponent']['township']res.append(adress)return res

2.路径规划

driving 可以换成walking
https://restapi.amap.com/v3/direction/driving?origin=116.45925,39.910031&destination=116.587922,40.081577&output=xml&key=<用户的key>

def get_route(origin，destination):key = '你的key'url = https://restapi.amap.com/v3/direction/driving?origin={origin}&destination={destination}&output=xml&key=<你的key>res = request.get(url)res = res.textjsonData=json.loads(res)return jsonData

def get_route_info(start,end):    routeplan=[]for o in start:for d in end:route=[]#起点route.append(o)#终点route.append(d)#起点终点转换为经纬度ori=address(o)des=address(d)#路线规划info=get_route(ori,des)#status为0时，info返回错误原；否则返回“OK”。详情参阅info状态表if info["info"]=='OK':#起终点步行距离try:walk_distance=info['route']['distance']except:walk_distance='null'route.append(walk_distance)# 路线出租车费用try:taxi_cost=info['route']['taxi_cost']except:taxi_cost='null'route.append(taxi_cost)#路线时间try:duration=info['route']['transits'][0]['duration']except:duration='null'route.append(duration)#路线费用try:price=info['route']['transits'][0]['cost']except:price='null'route.append(price)#路线距离try:distance=info['route']['transits'][0]['distance']except:distance='null'route.append(distance)print(o,d,taxi_cost,duration,price,distance)routeplan.append(route)return routeplan

3.搜索poi

#关键字搜索
https://restapi.amap.com/v3/place/text?keywords=北京大学&city=beijing&output=xml&offset=20&page=1&key=<用户的key>&extensions=all
#周边搜索
https://restapi.amap.com/v3/place/around?key=<用户的key>&location=116.473168,39.993015&radius=10000&types=011100
#多边形搜索
https://restapi.amap.com/v3/place/polygon?polygon=116.460988,40.006919|116.48231,40.007381|116.47516,39.99713|116.472596,39.985227|116.45669,39.984989|116.460988,40.006919&keywords=kfc&output=xml&key=<用户的key>
#id查询
https://restapi.amap.com/v3/place/detail?id=B0FFFAB6J2&output=xml&key=<用户的key>

def PolygonSearch(address_list):address = '|'.join(address_list)  # 用“|”拼接地址inputUrl = "https://restapi.amap.com/v3/place/polygon?polygon=" + address + "&offset=20&page=1&types=010000&output=json&key=0ff30ea4c08544b5df4ed773a5a6636f"response = requests.get(inputUrl)# 返回结果，JSON格式resultAnswer = response.json()# 返回结果中的状态标签，1为成功，0为失败resultStatus = resultAnswer['status']if resultStatus == '1':  # 返回成功# 读取返回的POI列表resultList = resultAnswer['pois']if len(resultList) == 0:  # 返回的POI列表为空print("当前返回结果为空！")else:# 返回的POI列表不为空，则遍历读取所有的数据for j in range(0, len(resultList)):saveId = str(resultList[j]['id'])  # POI编号saveName = str(resultList[j]['name'])  # POI名称saveType = str(resultList[j]['type'])  # POI类别saveTypecode = str(resultList[j]['typecode'])  # POI类别编号saveAddress = str(resultList[j]['address'])  # POI地址saveLocation = str(resultList[j]['location'])  # POI坐标print([saveId, saveName, saveType, saveTypecode, saveAddress, saveLocation])else:print("当前返回结果错误！")

4.天气查询

url = "https://restapi.amap.com/v3/weather/weatherInfo"
key = '你的key'
data = {'key': key, "city": 320100}
req = requests.post(url, data)
info = req.json()
