Question

所以我有这个问题，我有一个Java后端，它基本上是宁静的服务+数据库层，它从Javascript前端回答查询。

我有一个javascript ajax请求，可以在Chrome中完美运行，但在使用Firefox / IE时甚至无法访问服务器。

AJAX错误是： readyState = 0，status = 0，statusText =“error”

这是web.xml

ajax javascript调用

$(document).on('click', '.btn-login', function (event) {
    event.preventDefault();
    var holdUserName = document.getElementById("username1").value;
    var holdPass = document.getElementById("password1").value;
    Cookies.set('username', holdUserName, {expires: 1});
    console.log(Cookies.get('username'));
    console.log(holdUserName);
    console.log(holdPass);
    var logIn =
            {
                "username": holdUserName,
                "hash": holdPass
            };
    $.ajax({
        type: 'POST',
        async: false,
        cache: false,
        url: 'http://www.localhost:8080/library/login',
        contentType: "application/json",
        data: JSON.stringify(logIn),
        success: function (data, textStatus, xhr) {
            console.log(xhr.status);
            if (xhr.status == 200) {
                $(location).attr('href', 'runScript.html')
            }
        },
        error: function (error, xhr, ajaxOptions) {
            console.log(error);
            console.log(ajaxOptions);
            console.log(xhr.status);
            console.log(xhr.statusText);
        }
    })
});

休息服务

@POST
@Path("login")
@Consumes({MediaType.APPLICATION_JSON})
public Response login(@HeaderParam("authorization") String auth, User usr){
    System.out.println(usr.getUsername());
    System.out.println(usr.getHash());
    Object ok = false;
    try {
        ok = (new LoginHandler(usr.getUsername(),usr.getHash()).call());
    } catch (Exception e) {
        e.printStackTrace();
    }
    if(ok.equals(true)){
        return Response.status(200).build();
    }else{
        return Response.status(403).build();
    }
}

当我尝试向Postman提出对其余网络服务的请求时，我得到了回复，一切正常，Chrome也有效，但Firefox和IE让我头疼？有什么帮助吗？

非常感谢！

ajax post call在Firefox和IE中不起作用，Chrome可以正常工作
