C#代码移植到Python的结果不一样

C#代码移植到Python的结果不一样,python,c#,Python,C#,所以我最近进入了Python,我有一个项目,我正试图从C#移植到Python 为了进一步了解python的工作原理,我遇到了这个麻烦 我无法获得与C代码相同的输出 C#代码:将长度输出为46 static void Main(string[] args) { string json = "{\"id\":1,\"token\":\"testing\",\"type\":3,\"cmd\":1}"; send_request(json, 3, 1); Co

所以我最近进入了Python,我有一个项目,我正试图从C#移植到Python

为了进一步了解python的工作原理,我遇到了这个麻烦

我无法获得与C代码相同的输出

C#代码:将长度输出为46

static void Main(string[] args)
{
    string json =
        "{\"id\":1,\"token\":\"testing\",\"type\":3,\"cmd\":1}";
    send_request(json, 3, 1);

    Console.ReadKey();
}


private static void encrypt_decrypt(byte[] data)
{
    byte[] numArray = {250, 158, 179};

    for (int index = 0; index < data.Length; ++index)
    {
        if (data[index] != numArray[index % numArray.Length])
            data[index] = (byte) (data[index] ^ (uint) numArray[index % numArray.Length]);
    }
}

public static void send_request(string str, byte type, byte cmd)
{
    byte[] bytes = Encoding.UTF8.GetBytes(str);
    byte[] array = new byte[bytes.Length + 2];

    array[0] = type;
    array[1] = cmd;

    Buffer.BlockCopy(bytes, 0, array, 2, bytes.Length);

    encrypt_decrypt(array);
    send_message(array);
}

private static void send_message(byte[] message)
{
    byte[] array = new byte[message.Length + 1];
    Buffer.BlockCopy(message, 0, array, 0, message.Length);
    array[message.Length] = 0;

    Console.WriteLine(array.Length);
}
我做错了什么

感谢您的时间和努力。

对于C部分,这是因为您声明的数组长度为46。(
json.Length
最初是43,在
send_request
中添加+2后,
数组的大小将是45。)

注意
数组=新字节[message.Length+1]
。此时,
message.Length
为45。因此,添加+1将得到46,如
Console.WriteLine(array.Length)中所示

对于python,只是一个猜测:是否pythons
print(len(array))
只打印实际填充值的长度

def main():
    json = "{\"id\":1,\"token\":\"testing\",\"type\":3,\"cmd\":1}"
    send_request(json, 3, 1)

def encrypt_decrypt(data):
    r_list = [250, 158, 179]
    arr = bytearray(r_list)

    for i in range(len(data)):
        if data[i] is not arr[i % len(arr)]:
            data[i] = (data[i] ^ arr[i % len(arr)])


def send_request(str, type, cmd):
    print('Sending ' + str)
    str_bytes = bytes(str, 'utf-8')
    array = bytearray(len(str_bytes) + 2)
    array[0] = type
    array[1] = cmd
    array[0:2 + len(str_bytes)] = str_bytes
    encrypt_decrypt(array)
    send_message(array)


def send_message(message):
    array = bytearray(len(message) + 1)
    pos = 0
    array[pos:pos + len(message)] = message
    array[len(message)] = 0
    print(len(array))
