Hi all,
I am writing a lua script for downloading a file with authentication. In access_by_lua_file I'm calling an API by using lua http resty and getting response, If the response status is 200 I have to allow for downloading the requested file, Otherwise I should terminate the connection.
In header_filter_by_lua_file I'm setting all the headers for downloading a file.nginx.conf location /download {
access_by_lua_file "/etc/nginx/luaFiles/auth.lua";
header_filter_by_lua_file "/etc/nginx/luaFiles/header.lua";
alias "/uploads/";
}
access_by_lua_file: auth.lua
In this file i'm calling an API, if status code return by api is not equal to 200 then I should terminate the connection without allowing the file to download. Here I'm using ngx.exit with the status code to terminate the connection. But connection is not terminated it's still going in to the header_filter_by_lua_file.
if res then
if res.status==200 then
ngx.status=res.status
return
end
if res.status~=200 then
ngx.status=res.status
ngx.say("error code :",res.status)
return ngx.exit(res.status)
end
else
ngx.status=500
ngx.say("failed to request: ",err)
ngx.exit(500)
end
please help me to terminate the connection without going into header_filter_by_lua_file.
