Serveur Web minimal utilisant netcat

J’essaie de configurer un serveur Web minimal en utilisant netcat (nc). Lorsque le navigateur appelle localhost: 1500, par exemple, il doit afficher le résultat d’une fonction ( date dans l’exemple ci-dessous, mais finalement ce sera un programme python ou c qui génère des données). Mon petit serveur web netcat doit être une boucle while true dans bash, peut-être aussi simple que cela:

while true ; do echo -e "HTTP/1.1 200 OK\n\n $(date)" | nc -l -p 1500 ; done 

Lorsque j’essaie ceci, le navigateur affiche les données actuellement disponibles au moment où nc démarre. Je souhaite que le navigateur affiche les données au moment où le navigateur le demande. Comment puis-je atteindre cet objective?

    Essaye ça:

     while true ; do nc -l -p 1500 -c 'echo -e "HTTP/1.1 200 OK\n\n $(date)"'; done 

    -c fait que netcat exécute la commande donnée dans un shell, vous pouvez donc utiliser echo. Si vous n’avez pas besoin d’écho, utilisez -e . Pour plus d’informations à ce sujet, essayez man nc . Notez que lorsque vous utilisez echo , votre programme (le remplacement de date ) n’a aucun moyen d’obtenir la requête du navigateur. Donc, vous voulez probablement faire quelque chose comme ceci:

     while true ; do nc -l -p 1500 -e /path/to/yourprogram ; done 

    Où votre yourprogram doit faire le protocole comme gérer GET, envoyer HTTP 200 etc.

    Donno comment ou pourquoi mais je parviens à trouver ça et ça marche pour moi, j’avais le problème je voulais retourner le résultat de l’exécution d’un bash

     $ while true; do { echo -e 'HTTP/1.1 200 OK\r\n'; sh test; } | nc -l 8080; done 

    REMARQUE: cette commande provient de: http://www.razvantudorica.com/08/web-server-in-one-line-of-bash

    cela exécute le test de script bash et renvoie le résultat à un client de navigateur se connectant au serveur exécutant cette commande sur le port 8080

    Mon script fait cela ATM

     $ nano test #!/bin/bash echo "************PRINT SOME TEXT***************\n" echo "Hello World!!!" echo "\n" echo "Resources:" vmstat -SM echo "\n" echo "Addresses:" echo "$(ifconfig)" echo "\n" echo "$(gpio readall)" 

    et mon navigateur Web montre

     ************PRINT SOME TEXT*************** Hello World!!!

    simplement extraordinaire!

    Le problème auquel vous êtes confronté est que nc ne sait pas quand le client Web a terminé sa requête pour pouvoir répondre à la demande.
    Une session Web devrait aller quelque chose comme ça.

     TCP session is established. Browser Request Header: GET / HTTP/1.1 Browser Request Header: Host: www.google.com Browser Request Header: \n #Note: Browser is telling Webserver that the request header is complete. Server Response Header: HTTP/1.1 200 OK Server Response Header: Content-Type: text/html Server Response Header: Content-Length: 24 Server Response Header: \n #Note: Webserver is telling browser that response header is complete Server Message Body: sample html Server Message Body: \n #Note: Webserver is telling the browser that the requested resource is finished. The server closes the TCP session. 

    Les lignes commençant par “\ n” sont simplement des lignes vides sans même un espace et ne contiennent rien de plus qu’un nouveau caractère de ligne.

    J’ai mon bash httpd lancé par xinetd, tutoriel xinetd . Il enregistre également la date, l’heure, l’adresse IP du navigateur et l’intégralité de la requête du navigateur dans un fichier journal et calcule la longueur du contenu pour la réponse de l’en-tête du serveur.

     user@machine:/usr/local/bin# cat ./bash_httpd #!/bin/bash x=0; Log=$( echo -n "["$(date "+%F %T %Z")"] $REMOTE_HOST ")$( while read I[$x] && [ ${#I[$x]} -gt 1 ];do echo -n '"'${I[$x]} | sed -e's,.$,",'; let "x = $x + 1"; done ; ); echo $Log >> /var/log/bash_httpd Message_Body=$(echo -en 'Sample html') echo -en "HTTP/1.0 200 OK\nContent-Type: text/html\nContent-Length: ${#Message_Body}\n\n$Message_Body" 

    Pour append plus de fonctionnalités, vous pouvez les intégrer.

      METHOD=$(echo ${I[0]} |cut -d" " -f1) REQUEST=$(echo ${I[0]} |cut -d" " -f2) HTTP_VERSION=$(echo ${I[0]} |cut -d" " -f3) If METHOD = "GET" ]; then case "$REQUEST" in "/") Message_Body="HTML formatted home page stuff" ;; /who) Message_Body="HTML formatted results of who" ;; /ps) Message_Body="HTML formatted results of ps" ;; *) Message_Body= "Error Page not found header and content" ;; esac fi 

    Heureux bashing!

    Ajoutez -q 1 à la ligne de commande netcat :

     while true; do echo -e "HTTP/1.1 200 OK\n\n $(date)" | nc -l -p 1500 -q 1 done 

    J’ai eu le même besoin / problème mais rien ici n’a fonctionné pour moi (ou je n’ai pas tout compris), alors c’est ma solution.

    Je poste mon minimal_http_server.sh (en travaillant avec mon / bin / bash (4.3.11) mais pas avec / bin / sh à cause de la redirection):

     rm -f out mkfifo out trap "rm -f out" EXIT while true do cat out | nc -l 1500 > >( # parse the netcat output, to build the answer redirected to the pipe "out". export REQUEST= while read -r line do line=$(echo "$line" | tr -d '\r\n') if echo "$line" | grep -qE '^GET /' # if line starts with "GET /" then REQUEST=$(echo "$line" | cut -d ' ' -f2) # extract the request elif [ -z "$line" ] # empty line / end of request then # call a script here # Note: REQUEST is exported, so the script can parse it (to answer 200/403/404 status code + content) ./a_script.sh > out fi done ) done 

    Et mon a_script.sh (avec votre besoin):

     #!/bin/bash echo -e "HTTP/1.1 200 OK\r" echo "Content-type: text/html" echo date 

    Une autre façon de le faire

     while true; do (echo -e 'HTTP/1.1 200 OK\r\n'; echo -e "\n\tMy website has date function" ; echo -e "\t$(date)\n") | nc -lp 8080; done 

    Testons-le avec 2 requêtes HTTP en utilisant curl

    Dans cet exemple, 172.16.2.6 est l’adresse IP du serveur.

    Du côté serveur

     admin@server:~$ while true; do (echo -e 'HTTP/1.1 200 OK\r\n'; echo -e "\n\tMy website has date function" ; echo -e "\t$(date)\n") | nc -lp 8080; done GET / HTTP/1.1 Host: 172.16.2.6:8080 User-Agent: curl/7.48.0 Accept: */* GET / HTTP/1.1 Host: 172.16.2.6:8080 User-Agent: curl/7.48.0 Accept: */* 

    Côté client

     user@client:~$ curl 172.16.2.6:8080 My website has date function Tue Jun 13 18:00:19 UTC 2017 user@client:~$ curl 172.16.2.6:8080 My website has date function Tue Jun 13 18:00:24 UTC 2017 user@client:~$ 

    Si vous souhaitez exécuter une autre commande, n’hésitez pas à remplacer $ (date).

     mkfifo pipe; while true ; do #use read line from pipe to make it blocks before request comes in, #this is the key. { read line pipe; done 

    Voici une beauté d’ un petit serveur web bash , je l’ai trouvé en ligne et j’ai créé une copie et l’a redimensionné un peu – il utilise socat ou netcat je l’ai testé avec socat – il est autonome dans un script et génère son propre fichier de configuration et favicon.

    Par défaut, il démarre en tant que navigateur de fichiers compatible Web, mais il est facile à configurer par le fichier de configuration pour toute logique. Pour les fichiers, il diffuse des images et de la musique (mp3), de la vidéo (mp4, avi, etc.) – J’ai testé divers types de fichiers sur des appareils Linux, Windows et Android, y compris une smartwatch!

    Je pense qu’il diffuse mieux que VLC. Je l’ai trouvé utile pour transférer des fichiers à des clients distants qui n’ont pas access au-delà d’un navigateur Web, par exemple Android smartwatch, sans avoir à se soucier de la connexion physique à un port USB.

    Si vous voulez l’essayer, copiez et collez-le dans un fichier nommé bashttpd, puis lancez-le sur l’hôte avec $> bashttpd -s

    Vous pouvez ensuite aller sur n’importe quel autre ordinateur (en supposant que le pare-feu ne bloque pas les connexions TCP entrantes au port 8080 – le port par défaut, vous pouvez changer le port en fonction des variables globales en haut du script). http://bashttpd_server_ip:8080

    LOL, un piratage super boiteux, mais au moins curl et firefox l’accepte:

     while true ; do (dd if=/dev/zero count=10000;echo -e "HTTP/1.1\n\n $(date)") | nc -l 1500 ; done 

    Vous feriez mieux de le remplacer rapidement par quelque chose de bien!

    Ah oui, ma nc n’était pas exactement la même que la vôtre, elle n’aimait pas l’option -p .

    Tapez nc -h et voyez si l’option -e est disponible. Si oui, vous pouvez créer un script, par exemple:

    script.sh

     echo -e "HTTP/1.1 200 OK\n\n $(date)" 

    et lancez-le comme ceci:

     while true ; do nc -l -p 1500 -e script.sh; done 

    Notez que l’option -e doit être activée lors de la compilation pour être disponible.

    Je pense que le problème que toute la solution listée ne fonctionne pas, est insortingnsèque à la nature du service http, que chaque requête établie est avec un client différent et que la réponse doit être traitée dans un contexte différent, chaque requête doit générer un nouveau exemple de réponse …

    Je pense que la solution actuelle est le -e de netcat mais je ne sais pas pourquoi ça ne marche pas … peut-être est-ce ma version nc que je teste sur openwrt

    avec socat ça marche ….

    J’essaie ceci https://github.com/avleen/bashttpd

    et ça marche, mais je dois exécuter le script shell avec cette commande.

     socat tcp-l:80,reuseaddr,fork EXEC:bashttpd & 

    Les socat et netcat sur github ne fonctionnent pas pour moi, mais le socat que j’ai utilisé fonctionne.

    Si vous utilisez Apline Linux, le netcat de BusyBox est légèrement différent:

     while true; do nc -l -p 8080 -e sh -c 'echo -e "HTTP/1.1 200 OK\n\n$(date)"'; done
