   > As I've already said, if you want to send the request in the body_filter 
phase, you can use ngx.timer to do so,see: 
https://moonbingbing.gitbooks.io/openresty-best-practices/content/ngx_lua/timer.html
   
   yes i slove this problem like this 
   
   >      function _M.body_filter(conf, ctx) 
              local function push_data(premature, uri, args, status)
                  -- push the data uri, args, and status to the remote
                  -- via ngx.socket.tcp or ngx.socket.udp
                  -- (one may want to buffer the data in Lua a bit to
                  -- save I/O operations)
              end
              local ok, err = ngx.timer.at(0, push_data,
                                           ngx.var.uri, ngx.var.args, 
ngx.header.status)
              if not ok then
                  ngx.log(ngx.ERR, "failed to create timer: ", err)
                  return
              end
            end
    
   
   but my ngx.socket.tcp() always return 400 Bad Request ,how can i slove this 
problem
