Added the http_json_module with a json_set directive that
extracts values from JSON stored in nginx variables and exposes them
as new nginx variables. Parsed results are cached per request, so
multiple json_set directives using the same source expression trigger
only one parse. The directive is available in the http main context.
Example usage:
http {
json_set $user_name $arg_data user.name;
json_set $user_age $arg_data user.age;
json_set $tag0 $arg_data tags[0];
server {
listen 8080;
location / {
return 200 "name=$user_name age=$user_age "
"tag0=$tag0\n";
}
}
# quoted keys for names containing '.', '[', ']', or that
# are empty; the whole argument is single-quoted so that the
# inner '"' reach the path parser intact
json_set $host $arg_data '["a.b.com"]';
json_set $nested $arg_data 'obj["a.b"].c[2]';
json_set $quoted $arg_data 'obj["a\\"b"]';
}
