ExtJS跨域问题

Question

我是extjs的新手，我遇到了跨域问题。

Ext.Ajax.request({
    method: "POST",
 url:'url',
    params:{
        ahq_id: '104',
        username:'',
        password:'',
        callback:'WCL_Parser',
    },
    async: true,
    dataType: 'jsonp',
    success: function(response){
    console.info(response);

    }
});

我收到错误

 XMLHttpRequest cannot load http://182.73.236.115:8080/WCLRESTService/rest/Map/showVehiclesOnMap. Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:8282' is therefore not allowed access.

即使我尝试使用回调功能

    function WCL_Parser(data){
    console.info(data);
}

错误未解决。提前谢谢。
