Java调用BingAPI查询经纬度

2019独角兽企业重金招聘Python工程师标准>>>

代码为一个可直接使用的工具类

解析api返回json格式时，用了以下jart包

        
			net.sf.json-lib
			json-lib
			2.4
			jdk15
		
		
			org.apache.commons
			commons-lang3
			3.1
		
		
			commons-io
			commons-io
			2.0.1
		
		
			commons-beanutils
			commons-beanutils
			1.8.3
		

推荐使用fastJson来解析返回json，本例中未使用

		JSONObject jsonObject=new JSONObject().fromObject(result);
		String statusCode= jsonObject.getString("statusCode");
		if(statusCode.equals("200")){
			JSONArray resourceSets=(JSONArray) jsonObject.get("resourceSets");
			JSONObject resources=(JSONObject) resourceSets.get(0);
			JSONArray resource=(JSONArray) resources.get("resources");
			if(indexCount<2){
				if(resource.size()==0){
					indexCount++;
					coordinates=getLongitudeLatitude(country,state,postalcode,city,address);
				}else{
					JSONObject point=(JSONObject) resource.get(0);
					JSONObject object=new JSONObject().fromObject(point.getString("point"));
					coordinates=(JSONArray) object.get("coordinates");
					indexCount=0;
				}
			}else{
				indexCount=0;
				throw new IOException();
			}

		}
		return coordinates;


		
	}
}

Settings.getInstance().getString("bing.key")为申请的key请自行申请。

需要注意的的是微软的经纬度api不是每次都有返回值，如果地址格式正确，若没返回值可调用多次，直到取到值为止，例子中循环2次
