This paper studies a class of nonlinear Klein-Gordon equation. By using Fourier spectral method, we conduct the research on its direct problem and give the discrete process of finding solutions as well as do the numerical simulation and compare it with the result of literature. The result shows that the method has better effect on solving this kind of nonlinear Klein-Gordon equation.
