1.要獲取用戶歸屬地的天氣，首先得獲取用戶所在的市區，
這里先獲取用戶的IP，通過IP獲取IP的歸屬地，從而得到用戶
地址。
獲取客戶端ip:
js:
<scripttype="text/javascript" src="http://pv.sohu.com/cityjson?ie=utf-8"></script>
<scripttype="text/javascript">
alert(returnCitySN.cip)
</script>
獲取ip歸屬地：

{"code":0,"data":{"ip":"183.129.210.50","country":"中國","area":"","region":"浙江","city":"杭州","county":"XX","isp":"電信","country_id":"CN","area_id":"","region_id":"330000","city_id":"330100","county_id":"xx","isp_id":"100017"}}
新浪接口：http://int.dpool.sina.com.cn/iplookup/iplookup.php?format=js&ip=183.129.210.50
var remote_ip_info = {"ret":1,"start":-1,"end":-1,"country":"\u4e2d\u56fd","province":"\u6d59\u6c5f","city":"\u676d\u5dde","district":"","isp":"","type":"","desc":""}; ?
2.因為阿里云提供了通過城市名（city）或者城市編號（cityId）
即可獲取天氣的API，從而獲取用戶歸屬地天氣
var city1; $.ajax({//獲取客戶端 IP 和 歸屬地
url: "http://chaxun.1616.net/s.php?type=ip&output=json",
contentType:'application/json;charset=urt-8',dataType: "jsonp",success: function (data) {console.log('ip:' + data.Ip)console.log('歸屬地:' + data.Isp) var lcity = data.Isp.split(' ')[0];//獲取短名稱，如淮安市city1 = lcity.split('省')[1];console.log(city1)//因為是異步刷新，所以兩個請求幾乎同時進行 $.ajax({type: 'get',url: 'http://jisutqybmf.market.alicloudapi.com/weather/query',async: true,//設置驗證方式，設置請求頭//1，APPCodeheaders: { Authorization: "APPCODE 你的APPCode" },//2.APPSecret 暫時不能用//headers: { AppKey: '你的APPKey', AppSecret :'你的APPSecret' }, data: { city: city1 },success: function (result) {console.log(result['result'])//alert(result) },error: function () {alert('error')}});} });
?輸出結果：
