> I modify some input args at Line 281 of traffic-spllit.lua and try it in version 2.0 and there exist a bug. When I first send a request with "id = 1", it correctly chooses upstream_A. But after that, no matter what I send with "id = 1" or "id = 2", it always chooses upstream_A and never chooses upstream_B. > > Then I reload APISIX, this time I first send a request with "id = 2", it correctly chooses upstream_B. Then if I request with "id = 1" or "id = 2", it always chooses upstream_B. > > It seems that the problem is at Line 281 and Line 288 of traffic-split.lua > > > local rr_up, err = core.lrucache.plugin_ctx(plugin_name, ctx, new_rr_obj, weighted_upstreams) > > local upstream = rr_up:find() > > I print the log to see `weighted_upstreams` before Line 281 and it is correct. But Line 288 does not give the right output. Yes, this is a known bug. If you want to implement this function in APISIX 2.5, you can refer to the following PR to modify the traffic-split.lua code. https://github.com/apache/apisix/pull/4092/files#diff-95a2018f002f15f5fb0714075b5ef27a1db113c186bfe20ae705f6023080b38fL280-L283 -- This is an automated message from the Apache Git Service.
