天气预报 提供本地天气预报服务（含PM2.5，紫外线等指数）

提供本地天气预报服务，数据每20分钟更新一次，请点击天气预报，数据来源聊服务网

天气数据：

{"week":"星期四", "citynm":"上海", "temp":"20℃/15℃","weather":"中雨转多云", "air":"164", "sunriseTime":"05:24", "sunsetTime":"18:23", "Atm":"1010 hPa", "uv":"强", "rainfall":"70%", "cyzs":"温凉", "cyzs_desc":"一件羊毛衫、套装、夹克衫、西服套装、马甲衬衫+夹克衫配长裤年老体弱者：一件厚羊毛衫+夹衣或风衣 " }

获取本地天气的示例代码：

$.getJSON("http://tools.liaofuwu.com/weather.aspx?jsoncallback=?", function (json) {
			$("#div_Result").html("<b>" + json.week + " " + json.citynm + " " + json.temp + " " + json.weather + "<b/><br/><br/>");
		});

根据客户端IP获取本地天气的示例代码：

$.getJSON("http://tools.liaofuwu.com/weather.aspx?ip=180.154.13.153&jsoncallback=?", function (json) {
			$("#div_Result").html("<b>" + json.week + " " + json.citynm + " " + json.temp + " " + json.weather + "<b/><br/><br/>");
		});

接口实现的程序代码片断
