golang grpc client use gzip-Go服务器开发

To use gzip compression with golang grpc client, you need to enable it in the grpc.WithDefaultCallOptions function when creating your client connection. Here’s an example:

import (
	"compress/gzip"
	"context"
	"log"
	"net"

	"google.golang.org/grpc"
	"google.golang.org/grpc/encoding"
	pb "path/to/your/proto/package"
)

func main() {
	// create a dial option to enable gzip compression
	dialOption := grpc.WithDefaultCallOptions(grpc.UseCompressor(gzip.Name))

	// create a grpc client connection
	conn, err := grpc.Dial("localhost:50051", grpc.WithInsecure(), dialOption)
	if err != nil {
		log.Fatalf("failed to connect to grpc server: %v", err)
	}
	defer conn.Close()

	// create a grpc client
	client := pb.NewYourServiceClient(conn)

	// make a request
	req := &pb.YourRequest{...}
	resp, err := client.YourMethod(context.Background(), req)
	if err != nil {
		log.Fatalf("failed to call YourMethod: %v", err)
	}
	...

}

In the above example, we created a dial option grpc.WithDefaultCallOptions(grpc.UseCompressor(gzip.Name)) to enable gzip compression for all RPC calls made through this connection. We then passed this dial option to grpc.Dial() function to create a grpc client connection.

Note that the grpc server also needs to support gzip compression for this to work. To enable server-side gzip compression, you can use the grpc.WithDefaultCallOptions(grpc.UseCompressor(gzip.Name)) option when creating your server instance.
