将基本授权标头添加到某些请求

Question

I want to display a live mjpeg stream from a camera in my Spring-based web-application, and the camera requires basic authentication.

Since Chrome does not support authentication in urls anymore (see https://code.google.com/p/chromium/issues/detail?id=123150#c3 ), and I am using the webapp mostly on Android tablets with Chrome in a fullscreen/homescreen mode, I am in trouble.

The image tag, with embedded auth, which btw works in Firefox, would be like this:

<img src="http://username:password@the.camera.local/video.mjpeg" />

Is there a way with Spring to intercept the GET request for certain urls and add an Authorization header?

Edit 1

On the other hand, if I could manage to load the image url with an jQuery ajax-request, to which I can add username and password parameters.

Any hint on how to do that practically is welcomed.

Edit 2

In fact my initial question is flawed. The request for the image is done by the browser directly to the camera url, and thus can not be modified by Spring Security.

Probably the only solution is to load the image by Ajax.

Answer 1

I think using spring security would solve your purpose.

For Ex:- you can mention in spring-security.xml file,for which url you want to implement this.

<beans:beans xmlns="http://www.springframework.org/schema/security"
xmlns:beans="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans
      http://www.springframework.org/schema/beans/spring-beans-3.2.xsd
      http://www.springframework.org/schema/security
      http://www.springframework.org/schema/security/spring-security-3.1.xsd">

     <http>
        <intercept-url pattern="/video/*" access="ROLE_USER" />             
        <!-- Basic authentication -->
        <http-basic/>
    </http>     
    <authentication-manager>
        <authentication-provider>
            <user-service>
                <user name="test" password="test_pass" authorities="ROLE_USER" />
            </user-service>
        </authentication-provider>
    </authentication-manager>    
</beans:beans>

Configure web.xml for spring security and add the dependencies in pom.xml also.

Now when you try to access the resource /video/ ,for every succesful authentication,it would add Authorization header.

Answer 2

How can add basic authentication to some of the request? if i use spring security will add header to all requests.
