var GlobalStub func(ctx context.Context, method string, req, reply interface{},
	cc *grpc.ClientConn, invoker grpc.UnaryInvoker,
	opts ...grpc.CallOption) error

GlobalStub is test double and it is used when we cannot or don’t want to involve real server. Instead of the real server, we introduced a stub and defined what data should be returned. Example: func(ctx context.Context,

		method string, req, reply interface{}, cc *grpc.ClientConn,
		invoker grpc.UnaryInvoker, opts ...grpc.CallOption) error {
		if method == "/helloworld.Greeter/SayHello" {
			reply.(*pb.HelloReply).Message = "hello"
		}
		return nil
}

Functions

func ClientStubs

func ClientStubs(stubsFunc func(ctx context.Context, method string, req, reply interface{},
	cc *grpc.ClientConn, invoker grpc.UnaryInvoker,
	opts ...grpc.CallOption) error) func(ctx context.Context,
	method string, req, reply interface{}, cc *grpc.ClientConn,
	invoker grpc.UnaryInvoker, opts ...grpc.CallOption) error

func ServerStubs

func ServerStubs(stubsFunc func(
	ctx context.Context,
	req interface{},
	info *grpc.UnaryServerInfo,

) (resp interface{}, err error)) grpc.UnaryServerInterceptor

Types

type Client

type Client struct {
	// contains filtered or unexported fields
}

func NewClient

func NewClient(clientOptions *ClientOptions) *Client

NewClient create Client for business. clientOptions clientOptions can not nil. Deprecated: use NewClientWithOptionals instead.

func NewClientWithOptionals

func NewClientWithOptionals(options ...ClientOptional) *Client

func (*Client) Close

func (gc *Client) Close()

func (*Client) DialContext

func (gc *Client) DialContext(ctx context.Context, target string) *grpc.ClientConn

type ClientConn

type ClientConn struct {
	// contains filtered or unexported fields
}

Collect the grpc.ClientConn instances.

func NewClientConn

func NewClientConn(logger log.Logger) *ClientConn

func (*ClientConn) Close

func (cc *ClientConn) Close()

Close unity closes the grpc.ClientConn instances.

func (*ClientConn) CollectConn

func (cc *ClientConn) CollectConn(conn *grpc.ClientConn)

Examples：

client := grpc.NewClient(clientOptions)
ctx := context.Background()
conn := client.DialContext(ctx, ":50051")

clientConn := NewClientConn()
clientConn.CollectConn(conn).

func (*ClientConn) State

func (cc *ClientConn) State() []string

State unity show the grpc.ClientConn state.
