I have a request body that contains some numbers in JSON format. I need to forward that number to a specific host.
For example, I have 4 .csv files locally and I need just search if it's containing that number.
CSV files should compare the entries with an actual request body
file 1 - contains number 1 - if it's found in that file it should forward the request to host 1
file 2 - contains number 2 - if it's found in that file it should forward the request to host 2
file 3 - contains number 3 - if it's found in that file it should forward the request to host 3
file 4 - contains number 4 - if it's found in that file it should forward the request to host 4
Let me know if that is possible with lua nginx?
Update config 1
location /pathcall {
proxy_set_header X-Forwarded-Host $host;
proxy_set_header X-Forwarded-Server $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Url-Scheme $scheme;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_set_header Host $http_host;
proxy_redirect off;
proxy_ssl_verify off;
if ($request_method = POST ) {
set $upstream '';
rewrite_by_lua '
ngx.req.read_body()
local data = ngx.req.get_body_data()
1_file = "/opt/DATA/1.csv"
2_file = "/opt/DATA/2.csv"
file_1 = io.open(1_file)
1_data = file_1:read()
io.close(file_1)
1_outputdata = ngx.say(1_data)
file_2 = io.open(2_file)
2_data = file_2:read()
io.close(file_2)
local 2_outputdata = ngx.say(2_data)
local match0 = ngx.re.match(ngx.var.request_body, ngx.var.1_data )
local match1 = ngx.re.match(ngx.var.request_body, ngx.var.2_data )
if match0 then
ngx.var.upstream="host1"
elseif match1 then
ngx.var.upstream="host2"
else
ngx.var.upstream="host3"
end
';
proxy_pass https://$upstream ;
}
}
}
Seems it's not working still
