激发安全性401-使用Angularjs调用restful服务

我对spring安全性有问题。我已经完成了与我的用户的身份验证过程，但是当我通过angularjs调用restful服务时，出现了一个错误401

有什么想法吗？

也许一个解决办法就是用这种方式来解释这个方法

<intercept-url method="GET" pattern="/rest/secure/**" access="isAuthenticated()" />
<intercept-url method="PUT" pattern="/rest/secure/**" access="isAuthenticated()" />
<intercept-url method="POST" pattern="/rest/secure/**" access="isAuthenticated()" />
<intercept-url method="DELETE" pattern="/rest/secure/**" access="isAuthenticated()" />
