$ cd /home/ubuntu/hoge/test
$ vim api/
# api/

from flask import Flask, Blueprint

api = Blueprint('api', __name__) # apiをモジュールとして定義

def index():
    return 'This is api'


$ vim

import sys
sys.path.insert(0, '/home/ubuntu/hoge/test')

from flask import Flask
app = Flask(__name__)

from api.body import api
app.regster_blueprint(api, url_prefix='/api')

def index():
    return 'This is app route'

if __name__ = '__main__':'')

        # The ServerName directive sets the request scheme, hostname and port that
        # the server uses to identify itself. This is used when creating
        # redirection URLs. In the context of virtual hosts, the ServerName
        # specifies what hostname must appear in the request's Host: header to
        # match this virtual host. For the default virtual host (this file) this
        # value is not decisive as it is used as a last resort host regardless.
        # However, you must set it for any further virtual host explicitly.

        # For most configuration files from conf-available/, which are
        # enabled or disabled at a global level, it is possible to
        # include a line for only one particular virtual host. For example the
        # following line enables the CGI configuration for this host only
        # after it has been globally disabled with "a2disconf".
        #Include conf-available/serve-cgi-bin.conf
