Hands-On RESTful Web Services with Go - Second Edition

Creating an RPC server

Let's create a simple RPC server that sends the UTC server time back to the RPC client. The RPC server and RPC client should agree upon two things:

• Arguments passed
• Value returned

The types of these two parameters should match exactly for both server and client. Let's look at the steps for creating an RPC server, as follows:

touch -p $GOPATH/src/github.com/git-user/chapter3/rpcServer/main.go

2. We should create an Args struct and a reply pointer to hold data for RPC calls.
3. Then, create a function for a remote client to execute, and name it GiveServerTime, as shown in the following code block:

type Args struct{}type TimeServer int64func (t *TimeServer) GiveServerTime(args ...
