占位符应用

myTransport: function (data) {
return $http({
url: config.server + '/order/transport',
method: "post",
data: data
})
},
myTransportUpdate: function (data) {
var url = util.format('{0}/order/{1}/transport', config.server, data.id);
return $http({
url: url,
method: "put",
data: data
})
},

代码当中的{0}和{1}就是占位符，分别给config.server和data.id占位
