Re: Haproxy-LUA-RestAPI call

Thanks, Sean Conner,

I have updated the request and the response is in the red color, still am I missing anything?

core.Debug("actionlua called")
function check_ip(txn, addr,port)
core.Debug("actionlua called")
if not addr then addr ='3.226.158.233' end
if not port then port = 443 end
-- Set up a request to the service
local payload = [[{"email":"evtest@yopmail.com"}]]
local hdrs = {
[1] = string.format('host: %s:%s', addr,port),
[2] = 'Accept: application/json',
[3] = 'Content-Type: application/json',
[4] = string.format('Content-Length: %d',#payload)
}
local req = {
[1] = 'POST /evl/evIDLookUp HTTP/1.1',
[2] = table.concat(hdrs, '\r\n'),
[3] = '\r\n',
[4] = payload
}
req = table.concat(req, '\r\n')
print("req::",req)
-- Use core.tcp to get an instance of the Socket class
local socket = core.tcp()
-- Connect to the service and send the request

local connection = socket:connect(addr,port)
print("connection::",connection) -- connection:: 1
local res = socket:send(req)
print("res::",res) -- res::168
local rec = socket:receive("*a")
print("rec::",rec) -- rec:: nil
end
core.register_action('checkip', {'http-req'}, check_ip)

Thanks,

Going back to your original post, you gave the following code:

local payload = [[{"email":"evtest@yopmail.com"}]]

local hdrs = {
[1] = string.format('host: %s:%s', addr,port),
[2] = 'accept: application/json',
[3] = 'Content-Type: application/json'
}

local req = {
[1] = 'POST /evl/evIDLookU HTTP/1.1',
[2] = payload,
[3] = table.concat(hdrs, '\r\n'),
[4] = '\r\n'
}

req = table.concat(req, '\r\n')

Your request is formatted incorrectly. You have the payload between the
request and the headers, which isn't allowed by the HTTP spec. You are also
neglecting to set the Content-Length header. It should be:

local hdrs = {
string.format('Host: %s:%s',addr,port),
'Accept: application/json',
'Content-Type: application/json',
string.format('Content-Length: %d',#payload)
}

local res = {
'POST /evl/evIDLookU HTTP/1.1',
table.concat(hdrs,'\r\n'),
'\r\n',
payload
}
