为什么我得到[Errno 2]？

Question

因此，我创建了一台服务器，因为目前执行一个非常简单的任务，它假设将数据包发送到浏览器中包含“ datatatata”字符串。 但是它在运行它并从浏览器发送请求时不起作用，我会得到[ERRNO 2]。该请求当然是HTTP请求 代码：

import socket


# functions

def get_file_data(filename):
    pass


def handle_client_request(file_path, client_socket):
    file_to_return = open(file_path, 'rb')
    file_content = file_to_return.read()
    client_socket.send(file_content)


def validate_client_request(client_request):
    # checks validation of request. for now validation is set to true
    validation = True
    # checks for requested URL
    desired_file_name = ""
    for i in client_request[5::]:
        if i != " ":
            desired_file_name += i
        else:
            break
    # checking file type
    file_type = ""
    if desired_file_name == "favicon":
        file_type = "ico"
    elif desired_file_name == "abstruct" or desired_file_name == "":
        file_type = "jpg"
    elif desired_file_name == "loading":
        file_type = "gif"

    if file_type == "":
        validation = False

    file_path = "C:\\Users\\hadad\\Desktop\\webroot\\imgs\\" + desired_file_name + "." + file_type
    return validation, file_path


def handle_client(client_socket):
    client_request = client_socket.recv(1024).decode()
    valid_request, file_path = validate_client_request(client_request)
    if valid_request:
        handle_client_request(file_path, client_socket)
    else:
        client_socket.send("unvalid request. connection ended".encode())
    client_socket.close()


def main():
    server_socket = socket.socket()
    server_socket.bind(("0.0.0.0", 80))
    server_socket.listen()

    # everlasting loop
    while True:
        client_socket, client_address = server_socket.accept()
        handle_client(client_socket)


if __name__ == '__main__':
    main()

错误：
