刚刚去测试了一下,利用ajax的jsonp(跨域)的时候卡在了一个异常上:Uncaught SyntaxError: Unexpected token :。
这个异常是jd在对于ajax的跨域请求时没有对callback进行处理。所以无法让js获取到正确的json数据。
解决方案(php为例):用curl进行获取,也就是用后端做一次转发操作。jd官方也提供php的SDK。以下是我的jq的ajax代码 仅供参考。
$.ajax({url:'https://way.jd.com/showapi/address',
data: {
area:'鹿城',
areaid:'101210710',
needMoreDay:'0',
needIndex:'0',
needAlarm:'0',
need3HourForcast:'0',
appkey:'你申请的appkey',
ajax:1
},
type: "GET",
async:false,
dataType : "jsonp",
jsonp:'callback',
jsonpCallback:"jdwx",//jd返回json未对这个做处理导致js无法获取json
success: function (json) {
console.log(json)
},
error: function (msg) {
console.log(msg)
},
timeout:3000
})
