使用ajax獲取用戶所在地的天氣

　　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：

       淘寶接口：http://ip.taobao.com/service/getIpInfo.php?ip=183.129.210.50

{"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.因為阿里雲提供了通過城市名（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，APPCode
            headers: { 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')
            }
        });
    }
});
