Question

我有一项任务是使用ASP .NET core 2.0创建Web应用程序，您可以使用AT命令与调制解调器通信并发送SMS。我有一段代码可以使用串口发送消息，但ASP没有这个库，那么如何在ASP .NET中使用这段代码呢？
方法：

private SerialPort _serialPort;

    public void SendSms()
    {
        Console.WriteLine("Write phone number");
        string phoneNr = Console.ReadLine();
        Console.WriteLine("Write message");
        string message = Console.ReadLine();

        _serialPort = new SerialPort("COM2", 9600);

        Thread.Sleep(1000);

        _serialPort.Open();

        Thread.Sleep(1000);

        _serialPort.Write("AT+CMGF=1\r");

        Thread.Sleep(1000);

        _serialPort.Write("AT+CMGS=\"" + phoneNr + "\"\r\n");

        Thread.Sleep(1000);

        _serialPort.Write(message + "\x1A");

        Thread.Sleep(1000);

        _serialPort.Close();
    }

另外在我的应用程序中我有聊天窗口所以我想使用输入框和按钮来编写和发送短信。

 <form method="post">
            <input asp-for="MessageBody" id="textInput" type="text" placeholder="Enter message..." class="form-control " />
            <button asp-action="SendMessage" id="sendButton" class="btn btn-primary btn-block" type="submit">Send</button>
 </form>

现在 SendMessage 仅将消息保存到数据库中。
对不起，如果我的问题不是以最好的方式制定的，那么第一次写在这里。

Answer 1

您可以尝试在此行中添加“ \ n”吗？

_serialPort.Write("AT+CMGF=1\r");

应该是这样的

_serialPort.Write("AT+CMGF=1\r\n");

如何在asp .net核心中使用带串口的c＃方法？
