Web Service by Python

To develop web service with Python is really simple.

Here are 2 examples.

Demo 1, hello world.

#!/usr/bin/env python27

#!/usr/bin/python27

from wsgiref.simple_server import make_server

# A relatively simple WSGI application. It's going to print out Hello,

def simple_app(environ, start_response):

    status = '200 OK'

    headers = [('Content-type', 'text/plain')]

    start_response(status, headers)

    ret = 'Hello Friend.'

    return ret

httpd = make_server('', 7001, simple_app)

print "Serving on port 7001..."

httpd.serve_forever()

Demo 1.1, Print out the environment parameters.

from wsgiref.util import setup_testing_defaults

from wsgiref.simple_server import make_server

# A relatively simple WSGI application. It's going to print out the

# environment dictionary after being updated by setup_testing_defaults

def simple_app(environ, start_response):

    setup_testing_defaults(environ)

    status = '200 OK'

    headers = [('Content-type', 'text/plain')]

    start_response(status, headers)

    ret = ["%s: %s\n" % (key, value)

           for key, value in environ.iteritems()]

    return ret

httpd = make_server('', 7100, simple_app)

print "Serving on port 7100..."

httpd.serve_forever()
