python下的web服务器模块

python下的web服务模块有三种:

　　BaseHTTPServer: 提供基本的Web服务和处理器类，分别是HTTPServer和BaseHTTPRequestHandler

　　SimpleHTTPServer: 包含执行GET和HEAD请求的SimpleHTTPRequestHandler类

　　CGIHTTPServer: 包含处理POST请求和执行CGIHTTPRequestHandler类。

下面是CGIHTTPServer类示例：

root@u254:~/cp# tree
.
|-- cgi-bin
|   |-- get_info.py
|   |-- get_info.pyc
|   `-- hick.py
`-- http.py

http.py
#!/usr/bin/python
#encoding=utf-8
#supported by python2.7

import sys 
from CGIHTTPServer import CGIHTTPRequestHandler
from BaseHTTPServer import HTTPServer
server_addr = ('192.168.2.18', 20014)
httpd = HTTPServer(server_addr, CGIHTTPRequestHandler)
httpd.serve_forever()

hick.py
#!/usr/bin/python
#encoding=utf-8
#supported python2.7

import cgi
import sys
form = cgi.FieldStorage()
name = form["access"].value   #获取get传递的参数 

print "HTTP/1.0 200 OK"
print "Content-Type:text/html"
print ""
print ""
print "name %s"% name　　
print ""

执行效果图如下：　　

SimpleHTTPServer示例：

root@u254:~/cp# tree 
.
|-- get_info.py
|-- get_info.pyc
`-- http2.py

get_info.py如下：
#!/usr/bin/python
#encoding=utf-8
#supported python2.7

import commands
import json

def GetInfo(id):
        cmd = "radosgw-admin -c /etc/ceph/ceph.conf bucket stats  --uid="+ str(id) +" --categories={}"
        #cmd = "radosgw-admin bucket stats  --uid=37 --categories={} --access=radosgw-admin  --access-key=37 --secret=IXJcIub8Zprn7Vu+Tm3VId0LdrnMCfgpZ6sSb9zc"
        dict_t = {}
        content = commands.getoutput(cmd)
        #print content
        if content.find(")") != -1: 
                en_json = json.loads(content.split(')')[1])
        else:
                en_json = json.loads(content)
        for element in en_json:
                if "bucket" in element.keys() and "usage" in element.keys():
                        #print element["bucket"]
                        if "rgw.main" in element["usage"].keys() and "size_kb_actual" in element["usage"]["rgw.main"].keys():
                                #print element["usage"]["rgw.main"]["size_kb_actual"]
                                dict_t.setdefault(element["bucket"], element["usage"]["rgw.main"]["size_kb_actual"])
                        else:
                                dict_t.setdefault(element["bucket"], 0)
        #print json.dumps(dict_t) 
        return json.dumps(dict_t) 


if __name__ == "__main__":
    GetInfo(37)

http2.py如下：
#!/usr/bin/pyton
#encoding=utf-8
#supported by python2.7

def transDicts(params):
    dicts={}
    if len(params)==0:
        return
    params = params.split('&')
    for param in params:
        dicts[param.split('=')[0]]=param.split('=')[1]
    return dicts

if __name__=='__main__':
   try:
        server = HTTPServer(('203.156.196.254', 20014), MyRequestHandler)
        print 'started httpserver...'
        server.serve_forever()
   except KeyboardInterrupt:
        server.socket.close()
   pass

效果如下：
