[Closed] about get uvw Index of Vertex

hi all!
I want get all equals Index of Vertex, and then use function $.unwrap_uvw.unwrap.selectVertices() select equals index of vertex , and use function $.unwrap_uvw.unwrap.weldSelected() weld equals index of vertex.

problem : I can’t get uvw index of vertex ,i try use function $.unwrap_uvw.getVertexIndexFromFace and $.unwrap_uvw.getVertexGeomIndexFromFace unsucceed.
sorry for my bad english!!!
Any suggest would be greatly appreciated!
