使用线程时出现套接字问题

我在业余时间一直在研究python游戏,但我遇到了问题。我使用基本线程模块使用套接字,当我使用一个客户端连接到服务器文件时,它工作正常。但更重要的是,在第一次冻结服务器和第一个客户端之后连接的任何连接。

以下是服务器的代码

import socket
import random
import thread
from saveState import Save
from grid import Grid   
import time
players = 0
save = Save()
grid = Grid()

def ready(c):
    ready = raw_input("Are you ready to play?\n")
    if(ready == "yes" or ready == "y"):
        grid.makeGrid() 
        c.send("ready")
def clientThread(conn,players):

    while True:
        print "taking requests"
        request = conn.recv(1024)
        segments = request.split(",,")
        if(segments[0] == "0" and players<200):
            print "registering player", addr
            serial = random.choice(list(range(999999)))
            conn.send("{}".format(serial))
            save.players[serial] = segments[2:]
            print save.players[serial][9]
            players+=1
        elif(segments[0] == "3"):
            if(segments[2] == "land"):
                conn.send("{},,{},,{},,{}".format(grid.getLandType(int(save.players[serial][9]),int(save.players[serial][10])), grid.getDesc(int(save.players[serial][9]),int(save.players[serial][10])),int(save.players[serial][9]),int(save.players[serial][10])))
        elif(segments[0]=="2"):
            if(segments[2]=="playerX" and int(segments[3])==-1):
                save.players[serial][9] = int(save.players[int(serial)][9])-1 
            elif(segments[2]=="playerX"):
                save.players[serial][9] = int(save.players[int(serial)][9])+1 
            if(segments[2]=="playerY" and int(segments[3])==-1):
                save.players[serial][10] = int(save.players[int(serial)][10])-1 
            elif(segments[2]=="playerY"):
                save.players[serial][10] = int(save.players[int(serial)][10])+1 
        elif(segments[0]=="4"):
            alreadySent = []
            for m in grid.monsters:
                if(m.X==save.players[int[segment[1]]][9] and m.Y==save.players[int[segment[1]]][10] and alreadySent[m]==False):
                    conn.send("{},,{}".format(m.name, True))
                elif(time.clock == 60*60*(12+8)):
                    conn.send("{},,{}".format("You see the sun set on the horizon. Monsters will be more aggressive now.", False))
        else:       
            print "sorry, there is an inconsistency in the request or the queue is full."



try:
    #start up socket
    s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    name = socket.gethostbyname(socket.gethostname())
    print name
    port = input("select port\n")
    s.bind((name, port))
    s.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
    #listen for any attempts to connect to the api
    #if anyone connects, give them a serial number and add their data to a storage file
    while True: 
        s.listen(5)
        c,addr = s.accept()
        thread.start_new_thread(ready,(c,))
        thread.start_new_thread(clientThread,(c, players))
    conn.close
    sock.close
except socket.error:
    print " either the server port is closed or in use. try again"

我做了一些研究,我最好的猜测是我需要使用线程模块中的锁,但我不确定。有什么建议吗?

提前致谢!

答案 0 :(得分:0)

所以问题就是控制台输入,因为小天然没有说。没有严重的黑客攻击,这种限制并没有真正解决方法,所以我提议即兴发挥。我的解决方案是使用python而不是使用控制台创建Web应用程序。这有一些好处。

  • 服务器可以轻松地一次处理多个输入
  • 输入输入时可能发生的事情(我的问题的解决方案)
  • 无需为用户下载任何文件,因为只需输入网址即可访问所有文件。

虽然不是一个完美的解决方案,但有时候寻找替代方案是下一个最好的选择。

感谢所有人的大力帮助!
