调用百度api通过经纬度获取实际地理位置信息以及行政编码

需要用到百度地图api地址编码(有地址转经纬度)和逆地址编码功能(由经纬度转标准地址省市区)，去申请密钥进行调用。

申请密钥的时候不选择sn，可以避免后面的调用百度地图API报错'211'  sn校验失败。

地址编码官方文档：地理编码 | 百度地图API SDK (baidu.com)

逆地址编码官方文档：全球逆地理编码 rgc 反geo检索 | 百度地图API SDK (baidu.com)

主要实现代码：

# 2.调用百度api实现提取地点的经纬度
def getJingWei(address):
    url = "https://api.map.baidu.com/geocoding/v3"
    params = {
        "address": address,
        "output": "json",
        "ak": "你自己的ak密钥",
    }
    response = requests.get(url=url, params=params)
    result = response.json()
    # print(result)
    longitude = result['result']['location']['lng']  # 经度
    latitude = result['result']['location']['lat']  # 纬度
    lnglist.append(longitude)
    latlist.append(latitude)


# 3.通过经纬度获取地址信息（省市区）
def getAddress(lng, lat):
    response = requests.get('https://api.map.baidu.com/reverse_geocoding/v3/?ak=你自己的ak密钥&output=json&coordtype=wgs84ll&location='+str(lat)+','+str(lng))
    # if response:
    #     print(response.json())
    result = response.json()
    addlist.append(result['result']['formatted_address'])
    alllist.append(result['result']['addressComponent']['province']+','+result['result']['addressComponent']['city']+','+result['result']['addressComponent']['district']+','+result['result']['addressComponent']['adcode'])

 

print(list[0])
getJingWei(list[0])
print(lnglist[0],latlist[0])
getAddress(lnglist[0],latlist[0])
print(addlist[0])
print(alllist[0])

输出结果如下：

 

总实现代码，并且输出到指定的txt文件中：
