用于阻塞当前的线程，后面的操作不会进行，直到服务端断开。
 
import time
import socketio

sio = socketio.Client()
start_timer = None


def send_ping():
global start_timer
start_timer = time.time()
sio.emit('ping_from_client')


@sio.event
def connect():
print('connected to server')
send_ping()


@sio.event
def pong_from_server(data):
global start_timer
latency = time.time() - start_timer
print('latency is {0:.2f} ms'.format(latency * 1000))
sio.sleep(1)
send_ping()


if __name__ == '__main__':
sio.connect('http://localhost:5000')
sio.wait()
print('next')

比如上述代码中，如果调用了sio.wait() , 那么next是不会被打印的。
 
如果注释掉后，那么next就可以正常被打印。 查看全部
