I am using nginx and lua to parse my rest api (https://openresty-reference.readthedocs.io/en/latest/Lua_Nginx_API/) . I am trying to internally call another api inside my rest call which is a different server and return that response. But it is getting empty response always. Below is my config, I am requesting for /student any help is highly appreciable

location /student 
 content_by_lua '
 local str = "test"
 local res = ngx.location.capture("/detail",method = ngx.HTTP_POST, body = str)
 ngx.say(str)
 ';

location /detail 
 set $target '104.28.17.1/post';
 set $pass 'Basic Y2l28=';
 lua_need_request_body on;
 content_by_lua '
 proxy_set_header Host $host;
 proxy_set_header X-Real-IP $remote_addr;
 proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
 #access_by_lua '
 proxy_set_header Authorization $pass;
 proxy_set_header Content-Type 'application/x-www-form-urlencoded';
 proxy_set_header Accept '*/*';
 proxy_set_header Connection 'keep-alive';
 proxy_pass http://$target;

you can use resty.http to do a call in lua and write it to the body.
Below for a https call with authentication to an api:

-- load requirements 
http = require "resty.http"

local function api_request(ip, api_host, api_hostname, api_cred, api_url)
 local httpc = http.new()
 httpc:set_timeout(500)
 path = api_host .. string.format(api_url, ip)
 local response, err = httpc:request_uri(path,
 method = "GET",
 headers = 
 ["Authorization"] ="Basic " .. api_cred,
 ["Host"] = api_hostname,
 ,
 ssl_verify = false,
 )
 return response
end
