Python-HTTP-Server/ - Client: Remote end closed connection ohne Antwort Fehler

Machte ich einfache HTTP-Server mit BaseHTTPRequestHandler. Das problem ist, dass ich beim buchen möchten, einige Daten über die Anfragen vom client, ich bekomme ConnectionError. Ich habe einfache Anfrage von requests lib Dokumentation. Auch interessant ist, dass der HTTP-Server erhält die Daten von Kunden und drucken Sie es an die Konsole. Ich verstehe nicht, wie das ist möglich.

Client:

def post_data():
    """Client method"""
    json_data = {
        'sender': 'User',
        'receiver': 'MY_SERVER',
        'message': 'Hello server! Sending some data.'}
    data_headers = {'Content-type': 'application/json', 'Accept': 'text/plain'}
    data_payload = json.dumps(json_data)

    try:
        post = requests.post('http://localhost:8080/post', data=data_payload,
                             headers=data_headers)
        print(post.status_code)
    except ConnectionError as e:
        print("CONNECTION ERROR: ")
        print(e)

HTTP-Server:

def do_POST(self):
    """Server method"""
    self.send_response(200)
    print("Receiving new data ...")
    content_length = int(self.headers['Content-Length'])
    post_data = self.rfile.read(content_length)
    print(post_data)

Server Ergebnis:

C:\Users\mypc\Projects\PythonFiles\httpserver>python server.py
