jquery – getJSON Google Distance Matrix API – 语法错误

我正在使用CoffeeScript来执行get JSON请求：

$.getJSON(
    "http://maps.googleapis.com/maps/api/distancematrix/json?callback=?"
    origins: origin
    destinations: destinations
    sensor: false
    success: (data) -> 
        console.log data
   error: (data) ->
        console.log data
  'json'
)

网址是：

http://maps.googleapis.com/maps/api/distancematrix/json?callback=?&origins=-25.8350643,28.1636066&destinations=-25.551836,%2028.423075|-25.218503,%2027.923075|&sensor=false

如果你把它放在你的浏览器中,它将返回JSON,但是ajax请求告诉我：

Uncaught SyntaxError: Unexpected token:

有任何想法吗？

解决方法

该端点不支持(JSONP)回调.
你应该采用谷歌的方式：

var distanceService = new google.maps.distanceMatrixService();
    distanceService.getdistanceMatrix({
        origins: ['Istanbul,Turkey'],destinations: ['Ankara,travelMode: google.maps.TravelMode.DRIVING,unitSystem: google.maps.UnitSystem.METRIC,durationInTraffic: true,avoidHighways: false,avoidTolls: false
    },function (response,status) {
        if (status !== google.maps.distanceMatrixStatus.OK) {
            console.log('Error:',status);
        } else {
            console.log(response);
        }
    });
