var url = "http://ip地址:8080/test/?id=26323";
var params = {"billIds":["56141305725718528"],"billType":"VBNSC"}; 
var xhr = new XMLHttpRequest();
("POST", url, true);
("Content-Type", "application/json");
 = function (e) {
if ( === 4) {
	if ( === 200) {
	();
	} else {
	();
	}
	}
};
((params));
 = function (e) {
();
};

var url = "http://IP:8080/testGet?id=235";
var xhr = new XMLHttpRequest();
("GET", url, true);
// ("Content-Type", "application/json");
 = function (e) {
if ( === 4) {
	if ( === 200) {
	();
	} else {
	();
	}
	}
