jQuery-ajax-发布-json请求-在某些URL中没有发布主体

Question

I've been stuck at this for a while now. I have ajax request here:

$.ajax({
    url: UPDATE_USER_INFO_URL ,
    type: "POST",
    dataType: "json",
    contentType: "application/json",
    data: JSON.stringify({user:'user'}),
    success: function (data, textStatus) {
        if(data["statusCode"] && data["statusCode"] == 1) {
            _callback(1,data);
        }
        else {
            _callback(0,data);
        }
    },
    error: function (jqXHR, textStatus){
        _callback(0, {});
    }           
});

If I set UPDATE_USER_INFO_URL to a specific URL, fiddler show nothing in the body. If I set UPDATE_USER_INFO_URL to something else (even invalid URL), it does put {user:'user'} in the body in fiddler.

With original UPDATE_USER_INFO_URL:

Chage url to /SelfServiceWs/abcdef

{"user":"user"}

I have many other ajax calls, all are working as expected.

It must be little thing that I am missing.

Answer 1

I figured this out.

I have an authentication servlet filter to url /user/ssoauth, unexpectedly (to me), it made eveything call to URL under /user path (including /user/session/upduserinfo) to send out Authorization header. Moved filter to /user/auth/ssoauth stop client to send authorization header when calling user/session/upduserinfo and fix the problem.

<filter-mapping>
  <filter-name>SecurityFilter</filter-name>
  <url-pattern>/user/ssoauth</url-pattern>
</filter-mapping>

cause every client call to URL after /user to send Authorization header.

I learned something new today!

尝试这个

data: JSON.stringify({'user':'user'}),
