Description
local sock = ngx.req.socket(true)
local maxlen = 16*1024
local data = nil
local err = nil
local receivenum = 0
sock:settimeout(1900)
sock:settimeouts(2000, 2000, 2000) -- one second timeout for connect/read/write
local data, err = sock:receiveany(1024) -- read any data, at most 10K
if not data then
ngx.say("failed to read any data: ", err)
return
end
ngx.log(ngx.ERR,"read data:"..tostring(#data))
ngx.say("successfully read: ", data)
