用Python实现一个http server

# python2# coding = utf-8from BaseHTTPServer import HTTPServer, BaseHTTPRequestHandlerimport jsonclass RequestHandler(BaseHTTPRequestHandler):    def _set_headers(self):        self.send_response(200)        self.send_header('Content-type', 'application/json')        self.end_headers()    def do_GET(self):        response = {            'status':'SUCCESS',            'data':'hello from server'        }        self._set_headers()        self.wfile.write(json.dumps(response))    def do_POST(self):        content_length = int(self.headers['Content-Length'])        post_data = self.rfile.read(content_length)        print 'post data from client:'        print post_data        response = {            'status':'SUCCESS',            'data':'server got your post data'        }        self._set_headers()        self.wfile.write(json.dumps(response))def run():    port = 80    print('Listening on localhost:%s' % port)    server = HTTPServer(('', port), RequestHandler)    server.serve_forever()run()

 

python post json的两种方法:

# python2# coding = utf-8import jsonimport urllib2data = {    'key1':'value1',    'key2':'value2'}req = urllib2.Request('http://server_ip:server_port')req.add_header('Content-Type', 'application/json')response = urllib2.urlopen(req, json.dumps(data))print(response.read())

 

 

# python3# coding = utf-8import requestsmydict = {    'key1': 'value1',    'key2': 'value2'}r = requests.post("host:port/post", json=mydict)print(r.status_code)print(r.json())
