Mastering Go - Second Edition

The RPC client

In this section, you are going to see the Go code of the RPC client, which will be saved as RPCclient.go and presented in four parts.

The first part of RPCclient.go is as follows:

package main 
 
import ( 
    "fmt" 
    "net/rpc" 
    "os" 
    "sharedRPC" 
) 

The second segment of RPCclient.go contains the following Go code:

func main() { 
    arguments := os.Args 
    if len(arguments) == 1 { 
        fmt.Println("Please provide a host:port string!") 
        return 
    } 
 
    CONNECT := arguments[1] 
    c, err := rpc.Dial("tcp", CONNECT) 
    if err != nil { 
        fmt.Println(err) 
        return 
    } 

Observe the use of the rpc.Dial() function for connecting to the RPC server instead of the net.Dial() function, even though the RCP server uses TCP.

The third segment of RPCclient.go is as follows:

 args := ...
