A code generation method includes: after receiving a code generation request that carries a first question and is sent by the terminal device, the cloud computing platform decomposes the first question to obtain a step of resolving the first question; then, the cloud computing platform searches a code knowledge base based on each step in the step of resolving the first question, to obtain code knowledge matching each step; and finally, the cloud computing platform inputs each step in the step of resolving the first question and the code knowledge matching each step into a code generation model, to obtain code generated by the code generation model, and sends the code to the terminal device, for the terminal device to present the code.
