创建主窗口
root = tk.Tk()
root.title("阿里通义千问 AI 助手")
root.geometry("800x900") # 设置窗口大小

创建并放置 Prompt 输入框
prompt_label = tk.Label(root, text="Prompt:")
prompt_label.pack(pady=(10, 0))
prompt_text = scrolledtext.ScrolledText(root, height=10, width=80, wrap=tk.WORD)
prompt_text.pack(padx=10, pady=(0, 10), fill=tk.BOTH, expand=True)

创建并放置内容输入框
content_label = tk.Label(root, text="内容:")
content_label.pack()
content_text = scrolledtext.ScrolledText(root, height=15, width=80, wrap=tk.WORD)
content_text.pack(padx=10, pady=(0, 10), fill=tk.BOTH, expand=True)

创建并放置发送按钮
send_button = tk.Button(root, text="发送", command=send_message)
send_button.pack(pady=10)

创建并放置结果显示区域
result_label = tk.Label(root, text="AI 回答:")
result_label.pack()
result_text = scrolledtext.ScrolledText(root, height=20, width=80, wrap=tk.WORD)
result_text.pack(padx=10, pady=(0, 10), fill=tk.BOTH, expand=True)

运行主循环
root.mainloop()
