Socket while ne revient pas dans ma boucle

**gyver76370** · 29/10/2021, 11h21

Bonjour

je met en place une com par socket
J'ai un fichier client.py qui envoie les data vers le server avec une boucle while + input pour donner la commande mais ma boucle envoie une fois la command et ne reviens pas sur l'input
La parti server répond bien a mes commandes.
Je pense que c'est la partie socket qui bloque mais je ne vois pas quoi ?

Je pense que c'est la partie socket qui bloque mais je ne vois pas quoi ?

Il manque du code dans le client pour comprendre ce qu'il fait. Ceci dit, prenez le temps de faire un petit prototype, exemple de ce que vous voulez faire: un client qui envoie une commande à un serveur et attend sa réponse, c'est beaucoup moins de lignes de codes que celles que vous avez posté!
Et si vous ne faites pas cet effort, vous ne vous êtes pas focalisé sur la compréhension du problème à résoudre mais à faire fonctionner au plus vite votre application...

mauvais copier coller
le code """" client "" est le code de l'appareil que je pilote

j'ai mis le code du psu (appareil électronique piloter)

je remet le bon code lundi

désolé du dérangement

**gyver76370** · 29/10/2021, 20h02

bon j'ai regardé

et ca marche plus qu'a comparer avec le code que j'ai au boulot
je n'ai pas tout le code chez moi

bon weekend
