我使用此代碼本地消息響應擴展鉻
// background.js
chrome.runtime.sendNativeMessage("com.example.native",
{ text: "test" },
function(response) {
console.log("Received " + response);
});
C#代碼
private static void OpenStandardStreamOut(string stringData)
{
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));
Console.Write(msgdata);
}
private static List<LoginPack> OpenStandardStreamIn()
{
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();
}
JObject Read=(JObject)JsonConvert.DeserializeObject<JObject>(input);
//string dataPackStr = JsonConvert.SerializeObject(Read);
Chrome chromeClass = new Chrome();
List<LoginPack> lp = new List<LoginPack>();
if (Read!=null)
if (Read.Count != 0)
lp = chromeClass.getInfoFromChrome(Read["text"].ToString());
if (lp.Count == 0)
return null;
return lp;
}
//類鉻
public class Chrome
{
public class Data
{
public string key { get; set; }
public string value { get; set; }
}
public List<LoginPack> getInfoFromChrome(string colName)
{
try

應用(C#)給從擴展數據而擴展着如果我最初使用OpenStandardStreamOut
函數,可以從應用程序 得到任何迴應(在C#應用程序),然後擴展可以得到它的迴應 有什麼問題?
我已經讀過你的問題20次,但仍然不知道到底發生了什麼。 FYI本機應用程序由Chrome在執行重定向輸入和輸出流時執行,當擴展程序打開端口時,擴展程序始終是通信的發起者。 – wOxxOm
Actualy,Extension不會在postMessage之後從應用程序(C#)接收數據 – Mafia1990
在這種情況下,您需要顯示如何從您的擴展接收數據。您發佈的代碼沒有該部分。 – wOxxOm
