Windows上的Chrome原生消息

我认为它已经在等待答案,但不确定： Native app does not work in Chrome extension

在Linux上,它工作正常,但在Windows 7和8上,我总是收到错误“未找到指定的本机消息传递主机”.

这是我的注册表(我已尝试使用双反斜杠和HKEY_LOCAL_MACHINE)：

REG ADD HKEY_CURRENT_USER\SOFTWARE\Google\Chrome\NativeMessagingHosts\com.google.chrome.example.echo /ve /d C:\Users\Chriss\Desktop\nativeMessaging\host\com.google.chrome.example.echo-win.json

manifest.json的：

{
    // Extension ID: knldjmfmopnpolahpmmgbagdohdnhkik
    "key":"MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQDcBHwzDvyBQ6bDppkIs9MP4ksKqCMyXQ/A52JivHZKh4YO/9vJsT3oaYhSpDCE9RPocOEQvwsHsFReW2nUEc6OLLyoCFFxIb7KkLGsmfakkut/fFdNJYh0xOTbSN8YvLWcqph09XAY2Y/f0AL7vfO1cuCqtkMt8hFrBGWxDdf9CQIDAQAB","name": "Native Messaging Example","version": "1.0","manifest_version": 2,"description": "Send a message to a native application.","browser_action": {
    "default_title": "Test Extension","default_popup": "main.html"
    },"icons": {
    "128": "icon-128.png"
    },"permissions": [
    "nativeMessaging"
    ]
}

com.google.chrome.example.echo-win.json：

{
    "name": "com.google.chrome.example.echo","description": "Chrome Native Messaging API Example Host","path": "C:\Users\Chriss\Desktop\nativeMessaging\host\native-messaging-example-host.exe","type": "stdio","allowed_origins": [
    "chrome-extension://knldjmfmopnpolahpmmgbagdohdnhkik/"
    ]
}

本机的消息,例如,host.exe：

int main(int argc,char* argv[]) {
    // Define our message
    std::string message = "{\"text\": \"This is a response message\"}";
    // Collect the length of the message
    unsigned int len = message.length();
    // We need to send the 4 bytes of length information
    std::cout 
        << char(((len >> 0) & 0xFF))
        << char(((len >> 8) & 0xFF))
        << char(((len >> 16) & 0xFF))
        << char(((len >> 24) & 0xFF));
    // Now we can output our message
    std::cout << message;
    return 0;
}

JS片段(从http://src.chromium.org/viewvc/chrome/trunk/src/chrome/common/extensions/docs/examples/api/nativeMessaging/app/main.js?revision=228976开始)：

function connect() {
    var hostName = "com.google.chrome.example.echo";
    appendMessage("Connecting to native messaging host <b>" + hostName + "</b>")
    port = chrome.runtime.connectNative(hostName);
    port.onMessage.addListener(onNativeMessage);
    port.ondisconnect.addListener(ondisconnected);
    updateUiState();
}

我无法找出问题所在.我的错在哪里？

更新
使用Procces Monitor监控注册表.我发现chrome.exe在64位密钥中搜索密钥.现在我可以看到没有丢失相关的注册表项,但我仍然得到错误.

[HKEY_LOCAL_MACHINE\SOFTWARE\Google\Chrome\NativeMessagingHosts\tcchrome.native.handler]
@="G:\\\ExtChrome\\\Extension\\\Native\\\manifest.json"

{
    "name": "chrome.native.handler","description": "BlaBla helper process","path": "chrome.native.handler.exe","allowed_origins": [
    "chrome-extension://eoknpfoeckmeidbmbfoklejkppcnlfdm/"
    ]
}

cout.write((char*)&resSize,4);
cout.write(responseBuf,resSize);
