J'essaie de faire une requête "registerSensor". Voir le fichier xml suivant. Mais malheureusement, je reçois seulement une exception, à propos d'une requête NULL GET. Ce qui me trouble le plus, c'est le fait que j'envoie et que je lis par la méthode POST.Aucune réponse de (ogc) requête "Service d'observation de capteur" du serveur
Je sais que probablement ce problème ne correspond pas à ce forum, mais je ne sais pas où chercher d'autre .... (serait même heureux si vous venez de donner des conseils, à côté de l'ogc dokus)
Je l'ai testé deux fois sur mon propre serveur et aussi à: http: //giv-sos.uni-muenster.de: 8080/52nSOSv3/
ma demande:

Le ExceptionCode = "InvalidRequest" est assez évident, mais me confondez encore que je ne trouve pas et la moindre idée de ce dans le Doku ....
Je suis heureux de chaque réponse!
Y a-t-il quelqu'un qui a une idée ??? – user972851
