我在 REBOL2 中有这个代码:

port: open/direct tcp://localhost:8080
insert port request
result: copy port
close port

REBOL3 中的等价物是什么?

REBOL3 网络默认是异步的,所以 REBOL3 中的代码必须如下所示:

client: open tcp://localhost:8080
client/awake: func [event /local port] [
    port: event/port
    switch event/type [
        lookup  [open port]
        connect [write port to-binary request]
        read [
           result: to-string port/data
           close port
           return true
        ]
        wrote [read event/port]
    ]
    false
]
wait [client 30] ;the number is a timeout in seconds
close client
