Question

我正在开展示例应用＆＃34; Chrome原生消息＆＃34;。我根据网站上提到的步骤完成了所有设置。我也可以运行应用程序但是我没有从本机应用程序获得响应消息。当我第一次开始扩展时，我得到了响应消息。

当我从浏览器本机应用程序发送消息而没有响应时，请检查下面的图像

enter image description here

C＃代码如下

static void Main(string[] args)
    {
        string message = "test message from native app.";
        OpenStandardStreamOut(message);
        while (OpenStandardStreamIn() != null || OpenStandardStreamIn() != "")
        {
            OpenStandardStreamOut("Received to Native App: " + OpenStandardStreamIn());
            OpenStandardStreamOut("Recieved: " + OpenStandardStreamIn());
        }
    }

    private static string OpenStandardStreamIn()
    {
        //// We need to read first 4 bytes for length information
        Stream stdin = Console.OpenStandardInput();
        int length = 0;
        byte[] bytes = new byte[4];
        stdin.Read(bytes, 0, 4);
        length = System.BitConverter.ToInt32(bytes, 0);
        string input = "";
        for (int i = 0; i < length; i++)
        {
            input += (char)stdin.ReadByte();
        }
        return input;
    }

    private static void OpenStandardStreamOut(string stringData)
    {
        //// We need to send the 4 btyes of length information
        string msgdata = "{\"text\":\"" + stringData + "\"}";
        int DataLength = msgdata.Length;
        Stream stdout = Console.OpenStandardOutput();
        stdout.WriteByte((byte)((DataLength >> 0) & 0xFF));
        stdout.WriteByte((byte)((DataLength >> 8) & 0xFF));
        stdout.WriteByte((byte)((DataLength >> 16) & 0xFF));
        stdout.WriteByte((byte)((DataLength >> 24) & 0xFF));
        //Available total length : 4,294,967,295 ( FF FF FF FF )
        Console.Write(msgdata);
    }

manifest.json如下

  {"name": "com.example.native",
  "description": "Native support for Chrome Extension",
  "path": "NativeApp.exe",
  "type": "stdio",
  "allowed_origins": [
    "chrome-extension://knldjmfmopnpolahpmmgbagdohdnhkik/"
  ],
  "permissions": [
    "nativeMessaging"
  ]
}

我认为我们没有收到来自本机主机becoz的响应的一些我已经在浏览器中添加了以下代码的调试点，但没有被点击

function onNativeMessage(message) {

appendMessage（＆＃34;收到的消息：＆＃34; + JSON.stringify（消息）+＆＃34; ＆＃34;）; }

我错过了什么吗？

我遇到了同样的问题。确保您发送的消息是有效的JSON。就我而言，主机收到的值为"some value" ，带有双引号。当它被连接起来制作msgdata变量时，它就是在创建无效的JSON。
