Functions

func GRPCHandlerFunc added in v1.2.0 

func GRPCHandlerFunc(grpcServer *grpc.Server, otherHandler http.Handler) http.Handler

GRPCHandlerFunc uses the standard library h2c to convert http requests to http2 In this way, you can co-exist with go grpc and http services, and use one port to provide both grpc services and http services. In June 2018, the golang.org/x/net/http2/h2c standard library representing the "h2c" logo was officially merged in, and since then we can use the official standard library (h2c) This standard library implements the unencrypted mode of HTTP/2, so we can use the standard library to provide both HTTP/1.1 and HTTP/2 functions on the same port The h2c.NewHandler method has been specially processed, and h2c.NewHandler will return an http.handler The main internal logic is to intercept all h2c traffic, then hijack and redirect it to the corresponding handler according to different request traffic types to process. If a request is a h2c connection, it's hijacked and redirected to s.ServeConn. Otherwise the returned Handler just forwards requests to http.

func GetCtxValue
