我见过Bluemix的烧瓶示例项目:https://github.com/IBM-Bluemix/bluemix-python-flask-sample
如何从此烧瓶应用程序连接到Cloudant?

我为使flask sample project工作所采取的步骤:
welcome.py
和requirements.txt
源代码以连接到Cloudant。 (见下面的例子)cf push
将您的更改推送到Cloudant。http://yourbluemixurl/createdb/test
以创建名为' test' 示例代码:
<强> welcome.py 强>
import os
import json
import requests
from flask import Flask
app = Flask(__name__)
app.config.update(
DEBUG=True,
)
@app.route('/')
def welcome():
return 'Welcome to flask and Cloudant on Bluemix.'
@app.route('/createdb/<db>')
def create_db(db):
try:
vcap = json.loads(os.getenv("VCAP_SERVICES"))['cloudantNoSQLDB']
cl_username = vcap[0]['credentials']['username']
cl_password = vcap[0]['credentials']['password']
url = vcap[0]['credentials']['url']
auth = ( cl_username, cl_password )
except:
return 'A Cloudant service is not bound to the application. Please bind a Cloudant service and try again.'
requests.put( url + '/' + db, auth=auth )
return 'Database %s created.' % db
port = os.getenv('VCAP_APP_PORT', '5000')
if __name__ == "__main__":
app.run(host='0.0.0.0', port=int(port))
requirements.txt
Flask==0.10.1
requests==2.7.0
