python学习--服务期间通讯和mysql数据库操作

服务端

import socket
import json
s=socket.socket(socket.AF_INET,socket.SOCK_STREAM,0)
host=''
port=1234
s.bind((host,port))
s.listen(3)
while True:
        client,ipaddr=s.accept()
        print "Got a connect from %s" %str(ipaddr)
        data=client.recv(1024)
        metadata=json.loads(data)
        print "receive data:%s" %metadata[1]['name']
        client.send("echo:"+data)
        client.close()

客户端：

#! /usr/bin/env python
import socket
s=socket.socket(socket.AF_INET,socket.SOCK_STREAM,0)
host='localhost'
port=1234
s.connect((host,port))
#fileHandle = open('/root/test')
s.send('fileHandle')
data=s.recv(1024)
print "Reply from server----%s" %data

只要把客户端对应读取的文件 用json可是存数据  服务器端收到客户端发过来的数据

Python通过MySQL-Python把数据写进MySQL数据库

下载和安装

wget http://jaist.dl.sourceforge.net/project/mysql-python/mysql-python/1.2.3/MySQL-python-1.2.3.tar.gz
tar fvxz MySQL-python-1.2.3.tar.gz -C /usr/src/MySQL-python-1.2.3/
python setup.py build
python setup.py install

连接数据的代码：

,%s,%s,%s,%s￥

import MySQLdb
conn=MySQLdb.connect(host="localhost",user="root",passwd="123456",db="python",unix_socket="/tmp/mysql.sock")
cursor=conn.cursor()
sql = "insert into python values(%s,%s)"
param = (ip,status)
cursor.execute(sql,param)
conn.commit()
cursor.close()
conn.close()

把链接数据库的代码整合进服务器端的代码：

和服务器端写到一起
#!/usr/bin/env  python
import socket
import json
import MySQLdb
s=socket.socket(socket.AF_INET,socket.SOCK_STREAM,0)
host=''
port=1234
s.bind((host,port))
s.listen(3)
while True:
        client,ipaddr=s.accept()
        print "Got a connect from %s" %str(ipaddr)
        data=client.recv(1024)
        metadata=json.loads(data)
        ip = metadata[0]['ip']
        status = metadata[1]['status']
        conn = MySQLdb.connect(host="localhost",user="root",passwd="123456",db="python",unix_socket="/tmp/mysql.sock")
        cursor=conn.cursor()
        sql = "insert into python values(%s,%s)"
        param = (ip,status)
        cursor.execute(sql,param)
        conn.commit()
        cursor.close()
        conn.close()
        #print "receive data:%s" %metadata
        client.send("echo:"+data)
        client.close()

再添加一个故障处理，来处理从客户端接受的json格式数据key不符的问题，添加完的代码如下：

 

#!/usr/bin/env  python
import socket
import json
import MySQLdb
s=socket.socket(socket.AF_INET,socket.SOCK_STREAM,0)
host = ''
port = 1234
s.bind((host,port))
s.listen(3)
while True:
        client,ipaddr = s.accept()
        print "Got a connect from %s" %str(ipaddr)
        data=client.recv(1024)
        metadata=json.loads(data)
        try:
                ip = metadata[0]['ip']
                status = metadata[1]['status']
                conn = MySQLdb.connect(host="localhost",user="root",passwd="123456",db="python",unix_socket="/tmp/mysql.sock")
                cursor=conn.cursor()
                sql = "insert into python values(%s,%s)"
                param = (ip,status)
                cursor.execute(sql,param)
                conn.commit()
                cursor.close()
                conn.close()
                client.send("echo:"+data)
                client.close()
        except:
                client.send("Data ERROR")
                client.close()
