bug: wrong request forwarded to the upstream server

[lilililizheng]

Current Behavior

When using a reverse proxy, if in the request URL with parameters, such as: https://192.168.0.253:9443/hello? t=32132432, there will be an error when forwarding upstream. I have captured and traced the packet here, and there should be a coding problem when forwarding upstream. The request result I caught is GET hello%3F=32132432&t=32132432.

This can not be seen in the apisix log, the whole request is completely normal, but the wrong request was forwarded to the upstream server, the server can not handle the error correctly, this problem I roughly traced, it seems that there is a problem with the request:
function _M.set_current_peer(addr, port)
local r = get_request()
print(require("ffi").string(r))
if not r then
error("no request found")
end

if not port then
    port = 0
elseif type(port) ~= "number" then
    port = tonumber(port)
end

local rc = ngx_lua_ffi_balancer_set_current_peer(r, addr, #addr,
                                                 port, errmsg)
if rc == FFI_OK then
    return true
end

return nil, ffi_str(errmsg[0])

end
