java使用百度地图接口校验收货地址是否超出配送范围

1.地理编码

API服务地址：

https://api.map.baidu.com/geocoding/v3/?address=北京市海淀区上地十街10号&output=json&ak=您的ak&callback=showLocation

        Map map = new HashMap();
        map.put("address",shopAddress);
        map.put("output","json");
        map.put("ak",ak);
        //获取店铺的经纬度坐标
        String shopCoordinate =HttpClientUtil.doGet("https://api.map.baidu.com/geocoding/v3", map);
        //接收并解析来自 API 的响应，将其转换为 JSON 对象。        
        JSONObject jsonObject = JSON.parseObject(shopCoordinate);
        //检查响应中的 status 字段是否为 "0"。如果不是 "0"，则表示地理编码失败，抛出一个 OrderBusinessException 异常，异常信息为 "店铺地址解析失败"。
        if(!jsonObject.getString("status").equals("0")){
            throw new OrderBusinessException("店铺地址解析失败");
        }

2.数据解析

        //它从 JSON 对象中获取名为 "result" 的子对象，然后再从 "result" 对象中获取名为 "location" 的子对象。这个 "location" 对象包含了地理编码结果中的经纬度信息。
        JSONObject location = jsonObject.getJSONObject("result").getJSONObject("location");
        //分别从 "location" 对象中获取名为 "lat" 和 "lng" 的字段值，这些字段分别代表了纬度和经度的值。
        String lat = location.getString("lat");
        String lng = location.getString("lng");

3.店铺经纬度坐标

        String shopLngLat = lat + "," + lng;
        //将收货地址添加到map中
        map.put("address",address);

4.获取用户收货地址的经纬度坐标

        String userCoordinate = HttpClientUtil.doGet("https://api.map.baidu.com/geocoding/v3", map);
        jsonObject = JSON.parseObject(userCoordinate);
        if(!jsonObject.getString("status").equals("0")){
            throw new OrderBusinessException("收货地址解析失败");
        }
        //数据解析
        location = jsonObject.getJSONObject("result").getJSONObject("location");
        lat = location.getString("lat");
        lng = location.getString("lng");
        //用户收货地址经纬度坐标
        String userLngLat = lat + "," + lng;

5.驾车路线规划

API服务地址：

https://api.map.baidu.com/direction/v2/driving?origin=40.01116,116.339303&destination=39.936404,116.452562&ak=您的AK

        String json = HttpClientUtil.doGet("https://api.map.baidu.com/directionlite/v2/driving", map);
        jsonObject = JSON.parseObject(json);
        if(!jsonObject.getString("status").equals("0")){
            throw new OrderBusinessException("配送路线规划失败");
        }
        //数据解析
        JSONObject result = jsonObject.getJSONObject("result");
        JSONArray jsonArray = (JSONArray) result.get("routes");
        Integer distance = (Integer) ((JSONObject) jsonArray.get(0)).get("distance");
        if(distance > 5000){
            //配送距离超过5000米
            throw new OrderBusinessException("超出配送范围");
        }
