代理如何访问grpc服务中的请求标头。 Golang的grpc-gateway

I have a grpc server proxied by grpc-gateway. When I make a HTTP call to the gateway endpoint, my corresponding grpc service method is called. Now, the grpc service implementation receives a Context which has the headers. I couldn't figure out how to access the headers.

enter image description here

When I debug my grpc service and put a breakpoint, this is the structure of the Context object which my service receives. Now, how can I get the value of any of the HTTP request headers?

    HTTP headers are stored in metadata.

    md, ok := metadata.FromIncomingContext(ctx) should work for getting the incoming metadata.
