### Issue description 目的：想要根据分流规则，比如user-name=test，让流量跑到k8s集群中不同的ingress。 实现方法：使用nginx做为ingress controller，提供两个ingress controller的地址对外访问，通过改变Host，让流量跑到相应的ingress。详细配置见下面 遇到问题：traffic-split里面的upstream通过upstream_host字段不能正确改变Host字段，访问时报错404，不把upstream配在traffic-split里时没问题 ### Environment * apisix version (cmd: `apisix version`): 2.4 * OS (cmd: `uname -a`): Ubuntu 16.04.2 LTS * OpenResty / Nginx version (cmd: `nginx -V` or `openresty -V`): openresty/1.19.3.1 * etcd version, if have (cmd: run `curl http://127.0.0.1:9090/v1/server_info` to get the info from server-info API): 3.4.13 * apisix-dashboard version, if have: 2.4 ### 路由配置 curl http://127.0.0.1:9080/apisix/admin/routes/10 -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d ' { "uri": "/route10", "plugins": { "traffic-split": { "rules": [ { "match": [ { "vars": [ ["http_username", "==", "test"] ] } ], "weighted_upstreams": [ { "upstream": { "type": "roundrobin", "pass_host": "rewrite", "upstream_host": "echo-headers.pro.test-k8s.qslocal.com", "nodes": { "10.255.1.107:80":1, "10.255.1.108:80":1 } } } ] } ] } }, "upstream": { "type": "roundrobin", "pass_host": "rewrite", "upstream_host": "echo-headers.pro.test-k8s.qslocal.com", "nodes": { "10.255.1.107:80":1, "10.255.1.108:80":1 } } }' ### What's the actual result? (including assertion message & call stack if applicable) traffic-split插件中upstream_host改变没生效，流量到不了相应host的ingress，报错404 ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
