サーバー用に次のコードがあります。
public class TCPListener
{
public static void Main()
{
try
{
JSONMobile json_mobile = new JSONMobile();
IPAddress ip_address = IPAddress.Parse("127.0.0.1");
int port_number = 5000;
TcpListener server = new TcpListener(ip_address, port_number);
server.Start();
Byte[] bytes = new Byte[2048];
String received_data = null;
JObject obj = new JObject();
while (true)
{
TcpClient client = server.AcceptTcpClient();
received_data = null;
NetworkStream stream = client.GetStream();
int i;
while ((i = stream.Read(bytes, 0, bytes.Length)) != 0)
{
received_data = System.Text.Encoding.ASCII.GetString(bytes, 0, i);
obj = json_mobile.DeserializeToObject<JObject>(received_data);
string transaction_status = obj["Transaction_Status"].ToString();
string transaction_id = obj["Transaction_ID"].ToString();
string processed_date = obj["Processed_Date"].ToString();
string customer_username = obj["Customer_Username"].ToString();
byte[] msg = System.Text.Encoding.ASCII.GetBytes("The message was received!");
stream.Write(msg, 0, msg.Length);
}
client.Close();
}
}
catch (SocketException)
{
//Catch socket exception
}
}
クライアント用に次のコードがあります。
public bool sendTCPMessage(string ip_address, string port, string transaction_id, string customer_username, DateTime date)
{
bool success = false;
try
{
int converted_port = Convert.ToInt32(port);
string converted_date = date.ToString("dd/MM/yyyy HH:mm:ss", CultureInfo.InvariantCulture);
//int received_bytes_count = 0;
//string received_data = "";
JObject obj = new JObject();
obj["Transaction_Status"] = "Paid";
obj["Transaction_ID"] = transaction_id;
obj["Processed_Date"] = converted_date;
obj["Customer_Username"] = customer_username;
JSONMobile json_mobile = new JSONMobile();
string json = json_mobile.SerializeToString(obj);
//Send the JSON Object
TcpClient client = new TcpClient(ip_address, converted_port);
Byte[] sent_message = System.Text.Encoding.ASCII.GetBytes(json);
NetworkStream stream = client.GetStream();
stream.Write(sent_message, 0, sent_message.Length);
//Receive the response
/*Byte[] received_message = new Byte[2048];
received_bytes_count = stream.Read(received_message, 0, received_message.Length);
received_data = System.Text.Encoding.Default.GetString(received_message);*/
//Close the connection
stream.Close();
client.Close();
success = true;
}
catch (Exception)
{
success = false;
}
return success;
}
これで、Windows ファイアウォールでポート 5000 が開かれました。しかし、127.0.0.1 5000 (サーバー) に telnet しようとすると、悪い要求メッセージしか表示されません。明らかに、サーバーにブレークポイントを配置してクライアントを実行すると、ブレークポイントは決して入りません。何が問題ですか?私は何を間違っていますか?
