C++ Server und Client

iBinomic · Feb 23, 2012

Hallo,

eig. müsste es unter Windows doch möglich sein mithilfe einer in c++ erstellten Datei Daten zwischen dem PC auf dem das Programm gestartet wurde und einem zweiten auszutauschen?

Hat hierfür jmd. ein Codebeispiel?
Oder eine einfache Erklärung??

Ein kleines Chatprogramm, das auch Dateiversand ermöglicht würde vollkommen reichen.

Ich habe bereits gehört, dass es über WinSocks funktionieren soll, aber was wirklich brauchbares (für mich =D) hab ich leider nicht gefunden.

Das hier ist meine letzt Hoffnung ^^

Bis jetzt habe ich nur Erfahrung in relativ einfachen C++ Angelegenheiten.

Also die Boardsuche bringt einige Ergebnisse zu Tage (welche man sogar mit Google findet, wenn man denn sucht)

Winsock Tutorials

---

Nutzt man heutzutage von Hand aber weniger. Da nimmt man je nach Szenario was RPC-mäßiges (SOAP z.B.) oder Protokollbaukästen... REST wäre z.B. auch recht verbreitet. Für P2P Szenarien gibts auch irgendeine Baukastenlib...

WinSocket

Hallo,

leider gibt es in der C++ Standard-Bibliothek und auch im Sprachumfang keine Klassen oder Befehle, mit denen Socket-Verbindungen aufgebaut werden können. Hier ist man leider auf zusätzliche, Systemspezifische Bibliotheken wie die MFC oder die Win32 API angewiesen, oder man kauft kommerziele Bibliotheken zu. Daher gibt es keine Standard-Klassen oder Funktionen, die Systemübergreifend verwendet werden können, jedenfalls nichts was im C++ Standard definiert wäre. Schau mal unter www.boost.org nach, dort werden Bibliotheken für verschiedene Plattformen kostenlos angeboten.

Unter Windows könntest du z.B. mit der MFC wie folgt vorgehen:

Server side: SockServer.h

Dies ist allerdings nur eine rudimentäre Implementierung, die dir die Kommunikation mit eine einzigen Client ermöglicht.
Um mehrere Clients bedienen zu können muss nach dem Accept jedesmal ein neuer Thread gestartet werden, an den der resultierende Socket weitergegeben wird; das Hauptprogramm geht sofort wieder in den Accept zurück.

Hoffe, das hilf dir.

Anmerkung:
Wenn im Text von "Irda" die Rede ist: Ich hab das Ganze damals Testprogramm für eine Irda(Infrarot) Kommunikation geschrieben, die entsprechenden Options sind aber auskommentiert.
Das nur zur Info !

Ist das wirklich richtig so? Ich hab mir den Quellcode von dir jetzt nicht angeguckt, aber ich hab letztens noch ein Tutorial durchgearbeitet, müsste sogar das von C-Worker gesehen sein, und man kann aufjedenfall auch mit "select" arbeiten. Man nimmt einen akzeptierenden Socket auf dem Verbindungen angenommen werden und für jeden Clienten noch einen Socket dazu und "select" blockiert solange bis sich was auf einem Socket getan hat und den/die Sockets werden dann in ein FD_SET struct abgespeichert. Das liest man dann aus und bearbeitet die Anfragen.
Problematisch ist, dass während der Bearbeitung die neuen Anfragen warten müssen bis diese erst fertig sind. Bei vielen Clients ist für jeden Socket einen neuen Thread zu erstellen bestimmt auch nicht besser. Was besser ist hängt wohl von der Anzahl der Clients ab und zur Not vielleicht sogar eine Kombination aus beidem.

Für jeden Client einen eigenen Thread zu erstellen ist glaube ich wirklich nicht das wirtschaftlichste was man da machen kann.
AFAIK werden meist einem Thread x Clients übergeben. Außerdem erstellt der Server dann nach Bedarf bis zu y Threads, die ja jeweils x Clients halten können.
Zumindest für kleinere Projekte klappt das wunderbar.

Hallo auch,

die C# select Anweisung der .NET Extensions sollte man immer mit Vorsicht geniessen. Sie wird z.B. nicht sofort ausgeführt, sondern erst bei der Auswertung der einzelnen Member der Selection, ausserdem ist sie alles andere als schnell.
Ausserdem: Wenn der select blockiert, müssen die Clients erst mal warten, bis alle angemeldet sind (wann soll das sein ?). Der Socket ist ausserdem intern mit einer Art Warteschlange ausgestattet, deren Größe recht gering ist (vielleicht 3 Verbindungsanfragen); die 4. Verbindungsanfrage wird dann nicht akzeptiert und dadurch bekommst du immer nur ein Teilergebnis mit beim select. Daher ist immer ratsam, jede Verbindung einzeln zu handhaben und den Socket möglichst schnell wieder in einen Zustand zu versetzen, in dem ein neuer Client sich anmelden kann (sonst wird das zum Flaschenhals!), und das geht am besten mit Threading. Damit nicht jedesmal ein neuer Thread instanziert werden muß (Zeitaufwendig!), am besten ThreadPool benutzen.

Einem Thread mehrere Clients zuzuweisen, geht natürlich, aber es hängt von der Aufgabenstellung ab, ob das wirklich besser ist.

Schöne Grüße,

Ich muss gestehen: Ich hab keine Ahnung von C#, aber wie sind wir aufeinmal von C++ zu C# gekommen?

BieblSoft hat gesagt.:
Ausserdem: Wenn der select blockiert, müssen die Clients erst mal warten, bis alle angemeldet sind (wann soll das sein ?).

Die Clients melden sich über den Socket an der an dem Port gebunden ist. Wenn an diesem Port eine neue "Nachricht" eingeht bedeutet das, dass es eine neue Verbindung gibt. Diese wird dann auch generiert. Da der Socket der neue Verbindungen erstellt ebenfalls durchs select überwacht wird muss man nicht warten bis alle Clienten verbunden sind, sondern select blockiert eben nicht mehr, weil eine neue Nachricht eingegangen ist, nämlich auf dem Socket der neue Verbindungen annimmt.

BieblSoft hat gesagt.:
Der Socket ist ausserdem intern mit einer Art Warteschlange ausgestattet, deren Größe recht gering ist (vielleicht 3 Verbindungsanfragen); die 4. Verbindungsanfrage wird dann nicht akzeptiert und dadurch bekommst du immer nur ein Teilergebnis mit beim select.

Da hab ich ehrlich gesagt keine Ahnung. Kann man das irgendwo genauer nachlesen?

die C# select Anweisung der .NET Extensions sollte man immer mit Vorsicht geniessen. Sie wird z.B. nicht sofort ausgeführt, sondern erst bei der Auswertung der einzelnen Member der Selection, ausserdem ist sie alles andere als schnell.
Ausserdem: Wenn der select blockiert, müssen die Clients erst mal warten, bis alle angemeldet sind (wann soll das sein ?). Der Socket ist ausserdem intern mit einer Art Warteschlange ausgestattet, deren Größe recht gering ist (vielleicht 3 Verbindungsanfragen); die 4. Verbindungsanfrage wird dann nicht akzeptiert und dadurch bekommst du immer nur ein Teilergebnis mit beim select

@tsjuder:

Recht hast du, ich bin versehentlich in C# abgerutscht

weil ich da grad was machen musste...

Daher hab ich die select-Anweisungen verwechselt, denn die gibt es da auch.

In C++ hab ich mit Select nie gearbeitet, immer nur wie beschrieben .

Die Größe der Client Queue wird durch die listen-Funktion eingestellt (der int als 2. Argument), kann aber nur einen Maximalwert von 5 haben.
Nachlesen: CAsyncSocket::Listen

Übrigens entspricht die Socket-Implementierung von Microsoft dem internationalen Berkeley-Standard, daher ist dies auch unter anderen Systemen genauso.
