[zuiyangqingzhou]

Description

The requested link looks like this: GRPC -> apisix -> istio

At present, I need to change :authority in apisix layer and forward it to istio, istio does different work according to different :authority

Environment

• APISIX version (run apisix version):
• Operating system (run uname -a):
• OpenResty / Nginx version (run openresty -V or nginx -V):
• etcd version, if relevant (run curl http://127.0.0.1:9090/v1/server_info):
• APISIX Dashboard version, if relevant:
• Plugin runner version, for issues related to plugin runners:
• LuaRocks version, for installation issues (run luarocks --version):

Change the pseudo :authority should be same to change the host header. Try to use proxy-rewrite plugin.

Or just using the upstream_host field in Upstream object.

proxy-rewrite plugin does not work，the following is the OpenResty documentation

Or just using the upstream_host field in Upstream object.

This should only change the host, not the :authority ?

: authority should be identical with host, just try host.
