   I have resolve this problem:
   
   First Try: extend proxy-rewrite(add grpc and grpcs scheme) and change apisix bin file:
   ```
   location @grpc_pass {
               set $upstream_scheme             'grpc';
               access_by_lua_block {
                   apisix.grpc_access_phase()
               }
   
               grpc_set_header   Content-Type application/grpc;
               grpc_socket_keepalive on;
               grpc_pass         $upstream_scheme://apisix_backend;
   ...
   ```
   Problem: `grpc_pass` is different form `proxy_pass`, it cannot accept variable( which you defined by `set`).
   Result: `Failed`.
   
   Second Try：add other block in apisix bin file. and change jugement in init.lua
   ```
   location @grpc_pass_ssl {
               access_by_lua_block {
                   apisix.grpc_access_phase()
               }
   
               grpc_set_header   Content-Type application/grpc;
               grpc_socket_keepalive on;
               grpc_pass         grpcs://apisix_backend;
   ...
   ```
   
   Result: It works!
   
   I will close this issue now.
