### Description
i want to base on some condition to routing to different service
when i use `ctx.upstream_id = conf.upstream_id` it will routing to new
upstream
but when i use `ctx.service_id = conf.service_id `, it still routing to old
version
Cause we have plugins on service level , routing to new service will be
better than routing to a new upstream
May I know how can we mannually change service to annother service in plugin
code ?
```lua
local core = require("apisix.core")
local upstream = require("apisix.upstream")
local schema_def = require("apisix.schema_def")
local expr = require("resty.expr.v1")
local plugin_name = "custom-traffic-split"
local schema = {
type = "object",
properties = {
upstream_id = schema_def.id_schema,
service_id = schema_def.id_schema
}
}
local _M = {
version = 0.1,
priority = 966,
name = plugin_name,
schema = schema
}
function _M.check_schema(conf)
return core.schema.check(schema, conf)
end
function _M.access(conf, ctx)
if not conf then
return
end
--
local gary_release = core.request.header(ctx, "gary_version")
if not gary_release then
return
end
--
if conf.upstream_id then
ctx.upstream_id = conf.upstream_id
return
end
if conf.service_id then
ctx.service_id = conf.service_id
return
end
end
return _M
```
