Interface XsrfTokenService

All Known Implementing Classes:

DefaultXsrfTokenService

public interface XsrfTokenService

To be used in scenarios where the XsrfTokenInterceptor can not be applied.

The above mentioned XsrfTokenInterceptor, configured in the default stack, is the preferred method for securing XWork controllers (actions) against XSRF abuse.

This service should be used for the following scenarios instead:

• Servlets, as they have no notion of XWork
• Controllers handling Content-Type: multipart/form-data, as the underlying MultiPartRequestWrapper decoding the parts may escape on construction due to e.g. exceeding the maximum file size. Since the token will be encoded in a part, the token check would fail thus hiding the root cause.

Since:

5.1.4

Parameters:

request - the request used to identify the session, will be created if none is present

Returns:

a token pair to be used for the modifying request, containing the parameter key in the left part and the token value in the right part

validate
