angularjs ajax post跨域提交数据

前端设置

    /*插入分享API*/    .factory('AddShare', function ($http, host) {        return function (data) {            var paramArr=[];            for(var key in data){                paramArr.push(key+"="+data[key]);            }                return $http({                    method: 'POST',                    url: "http://192.168.253.1" + '/travelling-server/Home/Index/ajax_addShare',                    headers: {                        'Content-Type': 'application/x-www-form-urlencoded'                    },                    data: paramArr.join('&')                });            }    })

后台php设置

        header("Access-Control-Allow-Origin:*");        header("Access-Control-Allow-Headers:Content-Type,ACCESSTOKEN,VERSION,X-Requested-With");        header("Access-Control-Methods:GET,POST,OPTIONS");
