Hy Ladies and gentlemen :)

I have migrated my project from Apache2 and php7 to nginx with php-php, version 7 too.

With Apache2, everything worked.
With Nginx, only ajax fails.

With Ajax, i try to execute a php script.

Trying to determine where is the problem, i have :

-tested php code(echo and phpinfo), directly in html: it works.
-tested a javascript which change the appearances of my page : it works.
-tested in command line my script php : it works. ( The php script launch a sh script to reboot my Raspberry.)

In the javascript where is my ajax, i used success error and complete to return the result.
and the function of success and complete are executed. but the card doesn't reboot.

I have no error log from nginx and php-fpm :(

I've been looking into the problem for several days, which must be a big mistake on my part.

here the fonc of nginx :


#user nobody;
worker_processes 1;

#error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;

#pid logs/nginx.pid;


events {
worker_connections 1024;
}


http {
include mime.types;
default_type application/octet-stream;

#log_format main '$remote_addr - $remote_user [$time_local] "$request" '
# '$status $body_bytes_sent "$http_referer" '
# '"$http_user_agent" "$http_x_forwarded_for"';

#access_log logs/access.log main;

sendfile on;
#tcp_nopush on;

#keepalive_timeout 0;
keepalive_timeout 65;

#gzip on;

server {

server_name localhost;

#charset koi8-r;

#access_log logs/host.access.log main;

location / {
root /diagbox/web;
index intro.html;
}

error_page 550 /550.html;

# redirect server error pages to the static page /50x.html
#
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}




# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000

fastcgi_param SCRIPT_FILENAME /diagbox/web/$fastcgi_script_name;

}

# deny access to .htaccess files, if Apache's document root

#

# deny all;
#}
}

# location / {
# root html;
# index index.html index.htm;
# }
#}

# ssl_ciphers HIGH:!aNULL:!MD5;

}

here the js script :

//Constantes fonction reboot
const scripts_reboot = '../scripts/reset_reboot/reboot.php'
const mess_reboot = "La DiagBox redémarrera après avoir cliquer sur 'ok'. Tu pourras te reconnecter sur l'interface web d'ici 30 secondes environ :)"
const err_reboot = "Une erreur a empeché le redémarrage de la carte."

//Constantes fonction popup test debit
const php_download = "../scripts/test_debit/iperf_download_bouygues.php"
const php_upload = "../scripts/test_debit/iperf_upload_bouygues.php"
const php_ping = "../scripts/test_debit/iperf_ping.php"

function reboot(param1, param2) // param1 = smartphone ou tablette . param2 = oui ou non
{
if (param1 === 'tablette')
{
switch (param2)
{
case 'oui':
alert(mess_reboot);
$.ajax({
url: scripts_reboot,
});
break;

default:
choix_menu('accueil', 'tablette'); // Fonction accessible grace a la page html
break;
}
}

else if (param1 === 'smartphone')
{
switch (param2)
{
case 'oui':
alert(mess_reboot);
$.ajax({
url: scripts_reboot,
});
break;

default:
choix_menu('accueil', 'smartphone'); // Fonction accessible grace a la page html
break;
}
}

else
{
alert(err_reboot);
}

} //fin script reboot

Here the html code, the part which uses the js code :

<div id="reboot">
<h2 class="h2_reboot"> confirmer le redémarrage de la Diagbox ? </h2>
<input id="reboot_yes_tablette" type="button" value="Oui" class="tablette_bouton" onclick="reboot('tablette', 'oui');" /> <!-- Bouton pour oui -->
<input id="reboot_no_tablette" type="button" value="Non" class="tablette_bouton" onclick="reboot('tablette', 'non');" /> <!-- Bouton pour non -->
</div>

and here, the php code :

<?php
define('script_reboot', 'sh /diagbox/scripts/reset_reboot/reboot.sh');
echo exec(script_reboot);
?>


Thanks by advance :)
