I can't use subprocess with python-socketio
1
I ensure towork() function creates a thread, and in h5 I can receive 'ready to work'. But after subprocess.Popen(), I can't receive 'sucess' or 'failed', it seems stopped.
Any help ?
this is part of flask
@socketio.on('work')
def towork():
t=threading.Thread(target=test)
t.start()
def test():
socketio.emit('listen',{'res':'ready to work'})
cmd='dir'
out=subprocess.Popen(cmd,shell=True,stdout=subprocess.PIPE)
status=out.wait()
if status==0:
socketio.emit('listen',{'res':'sucess'})
else:
socketio.emit('listen',{'res':'failed'})
part of h5
socket.on("listen",function(msg){
$('#show').append(`<p>{msg.res}</p>`);
});
python flask socket.io subprocess
