python http server handle json

用Python实现一个http server

# python2
# coding = utf-8

from BaseHTTPServer import HTTPServer, BaseHTTPRequestHandler
import json

class 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-8

import json
import urllib2

data = {
    '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-8

import requests

mydict = {
    'key1': 'value1',
    'key2': 'value2'
}

r = requests.post("host:port/post", json=mydict)
print(r.status_code)
print(r.json())
