We propose a Finsler spacetime scenario of the anisotropic universe. The Finslerian universe requires both the fine-structure constant and the accelerating cosmic expansion to have a dipole structure and the directions of these two dipoles to be the same. Our numerical results show that the dipole direction of the SnIa Hubble diagram locates at 
with magnitude 
. The dipole direction of the fine-structure constant locates at 
with magnitude 
. The angular separation between the two dipole directions is about
