[GitHub] [apisix] jujiale opened a new issue, #8040: help request: apisix cloud't rewrite grpc header "host",with plugin proxy-rewrite
jujiale opened a new issue, #8040:
URL: https://github.com/apache/apisix/issues/8040
### Description
hello.
we are using apisix v2.12. several days ago, I asked a question: [https://github.com/apache/apisix/issues/7978](url), then I add the follwing config in ngx_tpl.lua
`
{% if use_apisix_openresty then %}
# For servers which obey the standard, when `:authority` is missing,
# `host` will be used instead. When used with apisix-base, we can do
# better by setting `:authority` directly
grpc_set_header ":authority" $upstream_host;
{% else %}
grpc_set_header "Host" $upstream_host;
{% end %}
`
then I use proxy-rewrite to modify the host. because we use apisix-base. so **grpc_set_header "Host" $upstream_host;** could not generate in nginx.conf when apisix start. the following is my config:
`
{
"uri": "/helloworld.Greeter/SayHello",
"name": "grpc-grpc",
"methods": [
"POST",
"GET"
],
"plugins": {
"proxy-rewrite": {
"host": "111.222.333.444"
}
},
"upstream": {
"nodes": [
{
"host": "172.25.219.22",
"port": 50051,
"weight": 1
}
],
"timeout": {
"connect": 6,
"send": 6,
"read": 6
},
"type": "roundrobin",
"scheme": "grpc",
"pass_host": "pass",
"keepalive_pool": {
"idle_timeout": 60,
"requests": 1000,
"size": 320
}
},
"status": 1
}
`
what I find is host is not modified as I mentioned in config. because we need "host" in header to modify. **so I don't konw why when we use apisix-base. it only set ":authority" instead of set "host"**. I am not familiar with grpc. wish your help. thanks.

I want to know when I need to modify the "host" or add "host" in grpc header, within current stiuation. should I modify the ngx_tpl.lua? because we have some upstream service which use "host" in grpc header

Host is special, even if you add the host via proxy-rewrite plugin, it will be converted to `:authority` when APISIX forwards requests to upstream.

`:authority` is identical to `host` in HTTP/2.

@tokers
I want to known. when our upstream grpc service picked host from grpc header "host", should I have some other way to add the header "host" to grpc header. because our upstream gprc service doesnot use header ":authority". and I find the grpc header doesnot have "host" default . I use proxy-rewrite plugin to add header. it failed too.
