小编Gia*_*aNU的帖子

我正在尝试使用XDomainRequest(IE8)对返回json的服务进行异步调用.问题是我总是得到一个错误(onerror事件被触发,而responseText总是为null),我正在使用fiddler检查服务的响应,我似乎是对的(我可以看到json对象的返回),这只发生在IE8中使用XDomainRequest时,JQuery中实现的相同功能可以正常工作.

任何线索将不胜感激.谢谢!

PS:这是我的javascript代码:

.....
  if (jQuery.browser.msie && window.XDomainRequest) {
    //Use Microsoft XDR
    var xdr = new XDomainRequest();
    xdr.open("post", url);
    xdr.onload = function () {
       alert("Loading");
       alert(xdr.responseText);
    };
    xdr.onsuccess = function() {
       alert("Success!");
       alert(xdr.responseText);
    };
    xdr.onerror = function() {
       alert("Error!");
       alert(xdr.responseText);
    };
    xdr.onprogress = function() {
       alert("Progress");
       alert(xdr.responseText);
    };
    xdr.timeout = 1000;
    xdr.send("data: " + escape(data));
    var response = xdr.responseText;
 } else .....

我正在尝试在注册后从控制器登录用户.我在控制器中的代码是:

...
User user = new User();
BeanUtils.copyProperties(userVO, user);

userService.save(user);

List<GrantedAuthority> grantedAuthorities = new ArrayList<GrantedAuthority>();
grantedAuthorities.add(new GrantedAuthorityImpl("USER"));

UsernamePasswordAuthenticationToken uat = new UsernamePasswordAuthenticationToken(user.getUsername(), user.getPassword(), grantedAuthorities);
uat.setDetails(user);
SecurityContext context = SecurityContextHolder.getContext();
Authentication userAuth = authenticationManager.authenticate(uat);

context.setAuthentication(userAuth);
 ...

在authenticationManager.authenticate(uat)行中我收到BadCredential Exception,我不知道为什么会这样.

有帮助吗？

堆栈跟踪是:
