Question

我是asyncio，aioconsole和curses的新手。我正在为应该与aairtc一起运行的聊天室编写模型。我想模拟聊天室中所有客户端之间的p2p连接。我使用curses构建了一个cli，现在尝试编写一个用于用户输入的异步输入函数。如何在我的诅咒窗口中整合aioconsole的ainput？

我已经将cli的evchat类包括在内。（https://github.com/EvanKuhn/evchat/tree/master/evchat）我还实现了生产者/消费者过程，该过程产生随机输出并将其打印到控制台。通常，它模拟几个人之间的活跃聊天。没有用户输入，程序将按预期运行。无需用户输入即可生成随机聊天记录。

                      layout.prompt_cols,
                      layout.prompt_start_row, layout.prompt_start_col)
        self.window.keypad(1)

        app.stop()

我希望Sepp＆Co.以随机间隔编写随机ipsum句子，而无需用户输入阻止聊天参与者编写内容。就像在whatsapp或其他聊天组中一样。目前，我只得到这个：我在聊天中写点东西。只有一个人答复，每个人都在等待用户的另一输入。

在Prompt类中没有帮助的是


async def getstr(self):
    "Get an input string from the user"
    text = await self.window.getstr()
    return text

或：


async def getstr(self):
    "Get an input string from the user"
    text = await ainput()
    self.window.addstr(text)

说实话，我不知道如何将输入输入到我的诅咒窗口中。预先感谢！

Answer 1

您可以使用getstr并使用简短的getch（或设置timeout）来代替nodelay。

如何为我的聊天室模型编写异步输入函数？
