Java调用BingAPI查询经纬度

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

        <dependency>
			<groupId>net.sf.json-lib</groupId>
			<artifactId>json-lib</artifactId>
			<version>2.4</version>
			<classifier>jdk15</classifier>
		</dependency>
		<dependency>
			<groupId>org.apache.commons</groupId>
			<artifactId>commons-lang3</artifactId>
			<version>3.1</version>
		</dependency>
		<dependency>
			<groupId>commons-io</groupId>
			<artifactId>commons-io</artifactId>
			<version>2.0.1</version>
		</dependency>
		<dependency>
			<groupId>commons-beanutils</groupId>
			<artifactId>commons-beanutils</artifactId>
			<version>1.8.3</version>
		</dependency>

推荐使用fastJson来解析返回json,本例中未使用

		String url ="http://dev.virtualearth.net/REST/v1/Locations/"+country+"/"+state+"/"+postalcode+"/"+city2+"/"+address2+"?o=json&key="+Settings.getInstance().getString("bing.key");

		System.out.println(url);

		HttpEntity httpEntity = resp.getEntity();
		String result = EntityUtils.toString(httpEntity);
		System.out.println(result);
		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
