webserver 接口的调用

webserver 接口的调用,街接口是.net定义的,接口的类型的json,可是我自己写的调用方法就是返回eooror

var SERVER_HOST = "http://192.168.1.13:81/";
var MODULE_LOGIN = "oaservice/dailyservice.asmx?op=getUserInfo"; //登录接口 //var MODULE_LOGIN = "mobileAPI?action=login";
var MODULE_SHOW_REQUEST_LIST = "oaservice/dailyservice.asmx?op=dailylist"; //查询,显示数据
var TOKEN_USER = "loginUserId";
var TOKEN_LOGIN = "loginToken";
var TOKEN_PROJECT_LIST = "projectList";
var PWD_CODE = "easking";

(function($, owner) {

owner.longpost = function(url, data, callback, waitingDialog) {  
    alert(JSON.stringify(data) + "---");  
    $.ajax(url, {  
        data: 'data=' + JSON.stringify(data), //获取登录信息, 用户名,秘密  
        dataType: 'json', //格式  
        type: "post", //提交方式  
        contentType: "application/x-www-form-urlencoded; charset=utf-8",  
        timeout: 10000, //请求时间  
        success:callback,  
        error: function(xhr, type, errorThrown) { //返回错误提示!  
            mui.alert("<网络连接失败，请重新尝试一下>", "错误", "OK", null);  
            waitingDialog.close(); //关闭等待提示框  
        }  
    });
