Method Detail

isCorsRequest

public static boolean isCorsRequest(ServerHttpRequest request)

Returns true if the request is a valid CORS one by checking Origin header presence and ensuring that origins are different via isSameOrigin(org.springframework.http.server.reactive.ServerHttpRequest).

isPreFlightRequest

public static boolean isPreFlightRequest(ServerHttpRequest request)

Returns true if the request is a valid CORS pre-flight one by checking {code OPTIONS} method with Origin and Access-Control-Request-Method headers presence.

isSameOrigin

@Deprecated
public static boolean isSameOrigin(ServerHttpRequest request)

Deprecated. as of 5.2, same-origin checks are performed directly by isCorsRequest(org.springframework.http.server.reactive.ServerHttpRequest)

Check if the request is a same-origin one, based on Origin, and Host headers.

Note: as of 5.1 this method ignores "Forwarded" and "X-Forwarded-*" headers that specify the client-originated address. Consider using the ForwardedHeaderFilter to extract and use, or to discard such headers.

Returns:

true if the request is a same-origin one, false in case of a cross-origin request
