写了个客户端程序总是卡，要不就发送数据失败，求高手指点
服务器程序：
import socket
import time
import MySQLdb
host='212.155.144.165'
port=34586
bufsiz=1024
ADDR=(host,port)
s=socket.socket(socket.AF_INET,socket.SOCK_STREAM)
s.setsockopt(socket.SOL_SOCKET,socket.SO_REUSEADDR,1)
s.bind(ADDR)
s.listen(5)
while 1:
print 'waiting for connection...'
data=sc.recv(bufsiz)
if data=='load':
sc.send('ok')
x=‘0’
sc,addr=s.accept()
data1=sc.recv(bufsiz)
a=data1.split('/')
db=MySQLdb.connect(host='localhost',user='root',
passwd='123',db='python')
cur=db.cursor()
r=cur.execute('select usernumber from user')
r=cur.fetchall()
ns=[]
for rec in r:
ns.append(rec)
n=[]
for i in range(0,len(ns)):
n.append(ns[i][0])
if a[0] in n:
p=cur.execute("select password from user where usernumber=%s"%n)
p=cur.ferchone()
ns1=[]
for rec in p:
ns1.append(rec)
if a[1]==ns1[0]:
x = ‘1’
break
s.send(x)
cur.close()
db.close()
sc.close()
s.close()




客户端程序:
import socket
import wx
import wx.grid
import MySQLdb
host='212.155.144.165'
port=34586
bufsiz=1024
ADDR=(host,port)
sc=socket.socket(socket.AF_INET,socket.SOCK_STREAM)
sc.connect(ADDR)
#登录界面
class LoginDialog(wx.Frame):

def __init__(self):
self.logindialog=wx.Frame.__init__(self, None, -1, "A202 系统", size=(300, 300))
panel = wx.Panel(self, -1)
label1=wx.StaticText(panel,-1,'用户登录',pos=(120,20))
label2=wx.StaticText(panel,-1,'用户名:',pos=(10,50))

wx.Choice(panel, -1, (80, 150), choices=sampleList)
self.button1=wx.Button(panel,-1,'确定',pos=(50,200))
self.button2=wx.Button(panel,-1,'取消',pos=(150,200))
self.Bind(wx.EVT_BUTTON, self.OnButton1, self.button1)
self.Bind(wx.EVT_BUTTON, self.OnButton2, self.button2)
self.button1.SetDefault()
def OnButton1(self,event):
sc.send('load')
data=sc.recv(bufsiz)
if data=='ok':
logindlg=LoginDialog()
data1=self.name.GetValue()
data2=self.password.GetValue()
data3=data1+'/'+data2
sc.send(data3)
y=sc.recv(bufsiz)
if y=='1':
frame=mainframe(self)
frame.Show()
logindlg.Destroy()
else:
wx.MessageBox('用户名不存在或密码错误，请重新输入!', '提示信息', wx.OK|wx.ICON_INFORMATION)
logindlg.Destroy()

def OnButton2(self,event):
self.Close()
class mainframe(wx.Frame):
。。。。。。。。。
if __name__ == '__main__':
app = wx.PySimpleApp()
frame=LoginDialog()
frame.Show(True)
app.MainLoop()

看到你跟我最近要做的工具有些类似，我就贴了你的代码修改了下，
我的电脑没装数据库所以把相关的都注掉了，你试下
服务器：

Python code

import socketimport time#import MySQLdbhost='192.168.24.212'port=34586bufsiz=1024ADDR=(host,port)s=socket.socket(socket.AF_INET,socket.SOCK_STREAM)s.setsockopt(socket.SOL_SOCKET,socket.SO_REUSEADDR,1)s.bind(ADDR)s.listen(5)while 1:  print 'waiting for connection...'  sc,addr=s.accept()  data=sc.recv(bufsiz)  print 'data:',data  if data=='load':    sc.send('ok')    x='0'    data1=sc.recv(bufsiz)    print 'data1:',data1    a=data1.split('/')    #function = functemp.split(':')    #db=MySQLdb.connect(host='localhost',user='root',    #passwd='123',db='python')    #cur=db.cursor()    #r=cur.execute('select usernumber from user')    #r=cur.fetchall()    #ns=[]    #for rec in r:    #  ns.append(rec)    #  n=[]    #for i in range(0,len(ns)):    #  n.append(ns[i][0])    #if a[0] in n:    #  p=cur.execute("select password from user where usernumber=%s"%n)    #  p=cur.ferchone()    #  ns1=[]    #for rec in p:    #  ns1.append(rec)    #if a[1]==ns1[0]:    #  x = '1'    #  break    sc.send('1')    print '1111111'    #cur.close()    #db.close()sc.close()s.close()

服务器那块有问题，客户端发送数据：sc.send(data3)发送不过去，阻塞了，

感觉我很嗦，你试试吧，我也是菜鸟~~~
