from flask import Flask,send_file
from flask import request
from flask import make_response

try:
  from urllib.parse import urlparse
except:
  from urlparse import urlparse

app = Flask(__name__)

base_path = ''

@app.route('/', methods=['GET', 'POST'])
def home():
#    resp = make_response('<h3>home<h3>', 200)
    return send_file("index.html")

@app.route('/signin', methods=['GET'])

    resp = make_response(html, 200)
    return resp

def handler(environ, start_response):
    parsed_tuple = urlparse(environ['fc.request_uri'])
    li = parsed_tuple.path.split('/')
    global base_path
    if not base_path:
        base_path = "/".join(li[0:5])
    return app(environ, start_response)
