Typescript将字节缓冲区转换为字符串

Question

根据我最初的问题

Ionic native push registration format changed?

我需要解析/转换

{"registrationId":"{length=32,bytes=0x459ca46ab66f4fe790220809215176d6...21b3436d13e78c64}","registrationType":"APNS"}

为字符串。看来字节后的值是我所需要的。 如何使用Typescript / javascript从该缓冲区解析出推送令牌？ 目标C解决方案似乎已经存在，但是现在我正在寻找打字稿解决方案。

+ (NSString *)stringFromDeviceToken:(NSData *)deviceToken {
    NSUInteger length = deviceToken.length;
    if (length == 0) {
        return nil;
    }
    const unsigned char *buffer = deviceToken.bytes;
    NSMutableString *hexString  = [NSMutableString stringWithCapacity:(length * 2)];
    for (int i = 0; i < length; ++i) {
        [hexString appendFormat:@"%02x", buffer[i]];
    }
    return [hexString copy];
}
