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：
1 root@u254:~/cp# tree 2 . 3 |-- cgi-bin 4 | |-- get_info.py 5 | |-- get_info.pyc 6 | `-- hick.py 7 `-- http.py 8 9 http.py 10 #!/usr/bin/python 11 #encoding=utf-8 12 #supported by python2.7 13 14 import sys 15 from CGIHTTPServer import CGIHTTPRequestHandler 16 from BaseHTTPServer import HTTPServer 17 server_addr = ('192.168.2.18', 20014) 18 httpd = HTTPServer(server_addr, CGIHTTPRequestHandler) 19 httpd.serve_forever() 20 21 hick.py 22 #!/usr/bin/python 23 #encoding=utf-8 24 #supported python2.7 25 26 import cgi 27 import sys 28 form = cgi.FieldStorage() 29 name = form["access"].value #获取get传递的参数 30 31 print "HTTP/1.0 200 OK" 32 print "Content-Type:text/html" 33 print "" 34 print "" 35 print "name %s"% name 36 print ""
执行效果图如下： 
SimpleHTTPServer示例：
1 root@u254:~/cp# tree 2 . 3 |-- get_info.py 4 |-- get_info.pyc 5 `-- http2.py 6 7 get_info.py如下： 8 #!/usr/bin/python 9 #encoding=utf-8 10 #supported python2.7 11 12 import commands 13 import json 14 15 def GetInfo(id): 16 cmd = "radosgw-admin -c /etc/ceph/ceph.conf bucket stats --uid="+ str(id) +" --categories={}" 17 #cmd = "radosgw-admin bucket stats --uid=37 --categories={} --access=radosgw-admin --access-key=37 --secret=IXJcIub8Zprn7Vu+Tm3VId0LdrnMCfgpZ6sSb9zc" 18 dict_t = {} 19 content = commands.getoutput(cmd) 20 #print content 21 if content.find(")") != -1: 22 en_json = json.loads(content.split(')')[1]) 23 else: 24 en_json = json.loads(content) 25 for element in en_json: 26 if "bucket" in element.keys() and "usage" in element.keys(): 27 #print element["bucket"] 28 if "rgw.main" in element["usage"].keys() and "size_kb_actual" in element["usage"]["rgw.main"].keys(): 29 #print element["usage"]["rgw.main"]["size_kb_actual"] 30 dict_t.setdefault(element["bucket"], element["usage"]["rgw.main"]["size_kb_actual"]) 31 else: 32 dict_t.setdefault(element["bucket"], 0) 33 #print json.dumps(dict_t) 34 return json.dumps(dict_t) 35 36 37 if __name__ == "__main__": 38 GetInfo(37) 39 40 http2.py如下： 41 #!/usr/bin/pyton 42 #encoding=utf-8 43 #supported by python2.7 44 45 46 #encoding=utf-8 47 from BaseHTTPServer import BaseHTTPRequestHandler, HTTPServer 48 import io,shutil 49 import urllib,time 50 import sys 51 sys.path.append(r'./') 52 import getopt,string 53 import get_info 54 55 class MyRequestHandler(BaseHTTPRequestHandler): 56 def do_GET(self): 57 self.process(2) 58 def do_POST(self): 59 self.process(1) 60 61 def process(self,type): 62 content ="" 63 if type==1: 64 datas = self.rfile.read(int(self.headers['content-length'])) 65 datas = urllib.unquote(datas).decode("utf-8", 'ignore') 66 datas = transDicts(datas) 67 if datas.has_key('data'): 68 content = "data:"+datas['data']+"\r\n" 69 70 if '?' in self.path: 71 query = urllib.splitquery(self.path) 72 action = query[0] 73 if query[1]: 74 queryParams = {} 75 for qp in query[1].split('&'): 76 kv = qp.split('=') 77 print kv[1] 78 kv[1] = get_info.GetInfo(kv[1]) 79 queryParams[kv[0]] = urllib.unquote(kv[1]).decode("utf-8", 'ignore') 80 #content+= kv[0]+':'+queryParams[kv[0]]+"\r\n" 81 content+= queryParams[kv[0]]+"\r\n" 82 83 enc="UTF-8" 84 content = content.encode(enc) 85 f = io.BytesIO() 86 f.write(content) 87 f.seek(0) 88 self.send_response(200) 89 self.send_header("Content-type", "text/html; charset=%s" % enc) 90 self.send_header("Content-Length", str(len(content))) 91 self.end_headers() 92 shutil.copyfileobj(f,self.wfile) 93 def transDicts(params): 94 dicts={} 95 if len(params)==0: 96 return 97 params = params.split('&') 98 for param in params: 99 dicts[param.split('=')[0]]=param.split('=')[1] 100 return dicts 101 102 if __name__=='__main__': 103 try: 104 server = HTTPServer(('203.156.196.254', 20014), MyRequestHandler) 105 print 'started httpserver...' 106 server.serve_forever() 107 except KeyboardInterrupt: 108 server.socket.close() 109 pass
效果如下：
