Quantum　secure　direct　communication　has　significant　theoretical　and　application　value,　which　can　safely　transmit　secret　information　without　pre-sharing　keys　between　legitimate　users.　Aiming　at　the　problems　of　uncontrollable　communication　capacity　and　complex　communication　process　of　certain　quantum　secure　direct　communication　protocols,　we　propose　a　three-party　quantum　secure　direct　communication　(3P-QSDC)　protocol　with　hyperentanglement　under　polarization　and　two　spatial　longitudinal　momentum　degrees　of　freedom　(DOFs).　The　secret　information　of　each　legitimate　user　is　encoded　by　using　corresponding　unitary　operations　in　three　degrees　of　freedom.　Compared　with　previous　3P-QSDC　protocols,　our　protocol　has　higher　information　capacity　and　can　reasonably　allocate　resources　to　realize　adaptive　mutual　communication　of　information　capacity　among　three　parties.　Additionally,　the　overall　analysis　indicates　that　by　inserting　decoy　photons　for　eavesdropping　detection,　the　proposed　protocol　has　better　security,　resisting　multiple　external　attacks　such　as　measure-resend　and　intercept-resend　attacks.　Our　protocol　is　expected　to　realize　applications　with　different　data　transmission　capabilities　between　multiple　parties　in　the　future.
