Web server gets blank requests in "receive" handler
Posted: Thu Feb 12, 2015 7:38 pmThis is a possible bug. I'm not sure.
I put an index in the "receive" handler for my simple web server and noticed that some of the payloads are just a single carriage return (and linefeed I guess). Seems like those should be filtered out before the handler. It might be an issue with the client sending over multiple carriage returns? Maybe trim all trailing "\r\n"?
(And if you have Verizon and make the client request from your mobile phone you'll see their evil zombie cookie.)

Code: Select all
wifi.setmode(wifi.STATION)
wifi.sta.config("SSID","password")
ip = wifi.sta.getip()
print(ip)
r = 0
s = 0
srv=net.createServer(net.TCP)
srv:listen(80,function(conn)
conn:on("receive",function(conn,payload)
print("r: "..r)
print(payload)
r=r+1
page = "<!DOCTYPE html><html><body><br/><br/>"
.."<h1>Receive count: "..r.."</h1>"
.."<br/><h1>Sent count: "..s.."</h1></body></html>"
conn:send(page)
end)
conn:on("sent",function(conn) s=s+1 conn:close() end)
end)
