pythonbase模块
‘壹’ python的BaseHTTPServer模块怎样接收post请求能给出，把接收到的POST数据输...

基于BaseHTTPServer的http server实现，包括get，post方法，get参数接收，post参数接收。

from BaseHTTPServer import BaseHTTPRequestHandler, HTTPServer

import os, sys
class MyRequestHandler(BaseHTTPRequestHandler):
def do_GET(self):
mpath,margs=urllib.splitquery(self.path) # ?分割
self.do_action(mpath, margs)
def do_POST(self):
mpath,margs=urllib.splitquery(self.path)
datas = self.rfile.read(int(self.headers['content-length']))
self.do_action(mpath, datas)
def do_action(self, path, args):
self.outputtxt(path + args )
def outputtxt(self, content):
#指定返回编码
enc = "UTF-8"
content = content.encode(enc)
f = io.BytesIO()
f.write(content)
f.seek(0)
self.send_response(200)
self.send_header("Content-type", "text/html; charset=%s" % enc)
self.send_header("Content-Length", str(len(content)))
self.end_headers()
shutil.fileobj(f,self.wfile)
‘贰’ 如何在Python中访问HBase的数据
Python连接HBase时需要先加载Thrift和HBase的相关包，之后创建与HBase的连接并进行后续操作，具体代码如下：
# -*- coding: utf-8 -*-
import sys
reload(sys)
sys.setdefaultencoding('utf-8')
from thrift.transport.TSocket import TSocket
from thrift.transport.TTransport import TBufferedTransport
from thrift.protocol import TBinaryProtocol
from hbase import Hbase
from hbase.ttypes import *
import pymongo
import hashlib
import time
from datetime import datetime
class HBaseOperator():
def __init__(self):
self.host = "ip_address"
self.port = 9090
self.transport = TBufferedTransport(TSocket(self.host, self.port))
self.transport.open()
self.protocol = TBinaryProtocol.TBinaryProtocol(self.transport)
self.client = Hbase.Client(self.protocol)
def __del__(self):
self.transport.close()
def getAllTablesInfo(self):
#get table info
listTables = self.client.getTableNames()
print "="*40
print "Show all tables information...."
for tableName in listTables:
print "TableName:" + tableName
print " "
listColumns = self.client.getColumnDescriptors(tableName)
print listColumns
print " "
listTableRegions = self.client.getTableRegions(tableName)
print listTableRegions
print "+"*40
‘叁’ Python怎么能简单实现Base64编码和解码
Base64编码是一种“防君子不防小人”的编码方式。广泛应用于MIME协议，作为电子邮件的传输编码，生成的编码可逆，后一两位可能有“=”，生成的编码都是ascii字符。
优点：速度快，ascii字符，肉眼不可理解
缺点：编码比较长，非常容易被破解，仅适用于加密非关键信息的场合
Python Base64编码和解码示例：
>>> import base64
>>> s = '我是字符串'
>>> a = base64.b64encode(s)
>>> print a
ztLKx9fWt/u0rg==
>>> print base64.b64decode(a)
我是字符串
