micropython esp32 uwebsockets 实现客户端与服务的通信

import uwebsockets.client
import os

def hello():
    with uwebsockets.client.connect('ws://139.196.55.124:8181') as websocket:

        uname = os.uname()
        name = '{sysname} {release} {version} {machine}'.format(
            sysname=uname.sysname,
            release=uname.release,
            version=uname.version,
            machine=uname.machine,
        )
        websocket.send(name)
        print("> {}".format(name))

        greeting = websocket.recv()
        print("< {}".format(greeting))

hello()

代码2：

import uwebsockets.client    
websocket = uwebsockets.client.connect("ws://echo.websocket.org/")    
mesg = "The quick brown fox jumps over the lazy dog"    
websocket.send(mesg + "\r\n")    
resp = websocket.recv()    
print(resp)    
assert(mesg + "\r\n" == resp)    
# close the socket to reclaim memory    
websocket.close()
