运行客户端程序

> library(websockets)
> client = websocket("ws://192.168.1.201",port=7681)
> rece<-function(DATA, WS, HEADER) { +   D='' +   if(is.raw(DATA)){ +     cat("raw data") +     D = rawToChar(DATA) +   } +   cat("==>",D,"\n")}
> set_callback("receive",rece, client)
> websocket_write("2222", client)
[1] 1

> service(client)
raw data==> You sent 2222

> websocket_close(client)
Client socket 3  was closed.

转行问题， 改为

> library(websockets)
> client = websocket("ws://192.168.1.201",port=7681)
> rece<-function(DATA, WS, HEADER) { 
+   D='' 
+   if(is.raw(DATA)){ 
+     cat("raw data") 
+     D = rawToChar(DATA) 
+   } 
+   cat("==>",D,"\n")
+}
> set_callback("receive",rece, client)
> websocket_write("2222", client)
[1] 1

> service(client)
raw data==> You sent 2222

> websocket_close(client)
Client socket 3  was closed.
