我正在尝试在我的 chrome 扩展程序和我的 c# 应用程序之间获取本地消息传递。javascript工作正常，但我收到此错误：
与本机消息传递主机通信时出错。
正如我从任务管理器中看到的那样，该应用程序确实与扩展程序一起启动。这是我的 C# 代码。
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 = stringData.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);
}
主要功能：
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());
}
}
JS代码：
var host_name = "com.example.native";
var port = null;
connectToNative();
function connectToNative() {
console.log('Connecting to native host: ' + host_name);
port = chrome.runtime.connectNative(host_name);
port.onMessage.addListener(onNativeMessage);
port.onDisconnect.addListener(onDisconnected);
sendNativeMessage("test");
}
function sendNativeMessage(msg) {
message = {"text" : msg};
console.log('Sending message to native app: ' + JSON.stringify(message));
port.postMessage(message);
console.log('Sent message to native app: ' + msg);
}
function onNativeMessage(message) {
console.log('recieved message from native app: ' + JSON.stringify(msg));
}
function onDisconnected() {
console.log(chrome.runtime.lastError);
console.log('disconnected from native app.');
port = null;
}
