有时,我们的后台接口有权限的限制,不满足权限,就返回错误码401,那么在js中如何判断呢?
if ((data.status && data.status == '401') || (data.statusText && data.statusText == 'No Transport')) { console.log(data); var currentUrl = window.location.href; window.location.href = currentUrl; return; }
下面是真实的返回:
Object {readyState: 4, responseText: "", status: 401, statusText: "Unauthorized"}
{readyState: 4, responseText: "", status: 401, statusText: "Unauthorized"}
java后台代码:
spring MVC拦截器中的部分代码:
if(StringUtil.isNullOrEmpty(token)){//added by huangwei logger.error("token is null"); response.setStatus(401); return false; }
优化如下:
