稳定高效的天气API接口是很少有的，本站前一段时间开发了一个万年历，需要带天气预报，花了几天功夫，集成和容错处理好对外开放的天气接口。天气接口支持返回 JSON 和 XML 结果。并且可以获取到昨天，以及今天和未来4 天的天气预报。那么下面直接介绍天气预报的接口吧。
天气预报 API 接口 JSON返回publicstaticvoidjson()throwsException{
//参数url化
Stringcity=.URLEncoder.encode("北京","utf-8");
//拼地址
StringapiUrl=String.format("/open/api/weather/json.shtml?city=%s",city);
//开始请求
URLurl=newURL(apiUrl);
URLConnectionopen=url.openConnection();
InputStreaminput=open.getInputStream();
//这里转换为String，带上包名，怕你们引错包
Stringresult=mons.io.IOUtils.toString(input,"utf-8");
//输出
System.out.println(result);
}
天气预报 JSON 返回值：{
