API response of FastAPI delete call-CodePudding

Is it necessary to return anything when a delete is successful, or does merely specifying the status code in the decorator do everything? For example:

@app.delete("/posts/{id}", status_code=status.HTTP_204_NO_CONTENT)
def delete_post(id: int):
    cursor.execute("DELETE FROM posts WHERE id=%s", (id,))
    conn.commit()
    return Response(status_code=status.HTTP_204_NO_CONTENT)

Or, can I remote the return statement entirely?

@app.delete("/posts/{id}", status_code=status.HTTP_204_NO_CONTENT)
def delete_post(id: int):
    cursor.execute("DELETE FROM posts WHERE id=%s", (id,))
    conn.commit()

CodePudding user response：

You can omit the return entirely, as the return code 204 is bound to not return any content. FastAPI replaces any content in 204, 304 and 1XX codes to b””.
