Распечатайте цветной текст к консоли в C++
Разобрался. Заменен sslStream.AuthenticateAsClient ("gateway.sandbox.push.apple.com"); с sslStream.AuthenticateAsClient ("gateway.sandbox.push.apple.com", clientCertificateCollection, SslProtocols.Default, false); И зарегистрировал сертификаты на ПК.
Редактировать: вот код для создания полезной нагрузки в соответствии с запросом:
private static byte[] GeneratePayload(byte [] deviceToken, string message, string sound)
{
MemoryStream memoryStream = new MemoryStream();
// Command
memoryStream.WriteByte(0);
byte[] tokenLength = BitConverter.GetBytes((Int16)32);
Array.Reverse(tokenLength);
// device token length
memoryStream.Write(tokenLength, 0, 2);
// Token
memoryStream.Write(deviceToken, 0, 32);
// String length
string apnMessage = string.Format ( "{{\"aps\":{{\"alert\":{{\"body\":\"{0}\",\"action-loc-key\":null}},\"sound\":\"{1}\"}}}}",
message,
sound);
byte [] apnMessageLength = BitConverter.GetBytes((Int16)apnMessage.Length);
Array.Reverse ( apnMessageLength );
// message length
memoryStream.Write(apnMessageLength, 0, 2);
// Write the message
memoryStream.Write(System.Text.ASCIIEncoding.ASCII.GetBytes(apnMessage), 0, apnMessage.Length);
return memoryStream.ToArray();
} // End of GeneratePayload

Ознакомьтесь с этим руководством . Я бы сделал собственный манипулятор, чтобы сделать что-нибудь вроде:
std::cout << "standard text" << setcolour(red) << "red text" << std::endl;
Вот небольшое руководство по реализации собственного манипулятора.
Быстрый пример кода:
#include <iostream>
#include <windows.h>
#include <iomanip>
using namespace std;
enum colour { DARKBLUE = 1, DARKGREEN, DARKTEAL, DARKRED, DARKPINK, DARKYELLOW, GRAY, DARKGRAY, BLUE, GREEN, TEAL, RED, PINK, YELLOW, WHITE };
struct setcolour
{
colour _c;
HANDLE _console_handle;
setcolour(colour c, HANDLE console_handle)
: _c(c), _console_handle(0)
{
_console_handle = console_handle;
}
};
// We could use a template here, making it more generic. Wide streams won't
// work with this version.
basic_ostream<char> &operator<<(basic_ostream<char> &s, const setcolour &ref)
{
SetConsoleTextAttribute(ref._console_handle, ref._c);
return s;
}
int main(int argc, char *argv[])
{
HANDLE chandle = GetStdHandle(STD_OUTPUT_HANDLE);
cout << "standard text" << setcolour(RED, chandle) << " red text" << endl;
cin.get();
}
I did a search for "c++ console write colored text" and came up with this page at about 4 or 5. As the site has a copy & paste section I thought I'd post it here (another question on link rot also prompted this):
#include <stdlib.h>
#include <windows.h>
#include <iostream>
using namespace std;
enum Color { DBLUE=1,GREEN,GREY,DRED,DPURP,BROWN,LGREY,DGREY,BLUE,LIMEG,TEAL,
RED,PURPLE,YELLOW,WHITE,B_B };
/* These are the first 16 colors anyways. You test the other hundreds yourself.
After 15 they are all combos of different color text/backgrounds. */
bool quit;
void col(unsigned short color)
{
HANDLE hcon = GetStdHandle(STD_OUTPUT_HANDLE);
SetConsoleTextAttribute(hcon,color);
}
istream &operator>> ( istream &in, Color &c )
{
int tint;
cin >> tint;
if (tint==-1) quit=true;
c=(Color)tint;
}
int main()
{
do {
col(7); // Defaults color for each round.
cout << "Enter a color code, or -1 to quit... ";
Color y;
cin >> y; // Notice that >> is defined above for Color types.
col(y); // Sets output color to y.
if (!quit) cout << "Color: " << (int)y << endl;
} while (!quit);
return 0;
}
