The Grpc server is defined in the “cluster”

Currently, HTTP requests only support JSON body parsing parameters.

Prepare the Server

generate pb files under with command:

protoc --go_out=. --go_opt=paths=source_relative --go-grpc_out=. --go-grpc_opt=paths=source_relative hello_grpc.proto

Start the Server

Run

go run server.go

Start Pixiu

./dubbo-go-pixiu gateway start --config {CURRENT_PATH}/samples/http/grpc/pixiu/conf.yaml

Test Using Curl

Run the curl command with the following:

curl http://127.0.0.1:8881/api/v1/provider.UserProvider/GetUser

curl http://127.0.0.1:8881/api/v1/provider.UserProvider/GetUser -X POST -d '{"userId":1}'

If the response body is JSON, the Content-Type header will be set to application/json. If it is just plain text, the Content-Type header is text/plain.
