这是来自MongoLab的。 我们有一个通用的例子,说明如何利用官方假日司机(pymongo)在沙里连接起来。 这个例子并不是要从Heroku说来连接,而是应该这样。 不同之处在于,你需要把你的司机从你的Heroku ENV环境中conf,向司机供应。

Im 采用以下方法:
import os
from urlparse import urlsplit
from pymongo import Connection
url = os.getenv( MONGOLAB_URI , mongodb://localhost:27017/testdb )
parsed = urlsplit(url)
db_name = parsed.path[1:]
# Get your DB
db = Connection(url)[db_name]
# Authenticate
if @ in url:
user, password = parsed.netloc.split( @ )[0].split( : )
db.authenticate(user, password)
在安装了信oku后,通过在指挥线上运行<代码>heroku config进入连接线。
即将进入非政府组织会议部。 URI以这种形式:
<>code>MONGOLAB_URI => mongodb http://user:[电子邮箱::27707/db
简言之,通过从里面铺设一条连接线,从古丁的里叶中穿透。
我认为,应该做些什么:
import os
import sys
import pymongo
mongo_url = os.getenv( MONGOLAB_URI , mongodb://localhost:27017 )
db_name = mongotest
if __name__ == __main__ :
try:
connection = pymongo.Connection(mongo_url)
if localhost in self.mongo_url:
db_name = my_local_db_name
else:
db_name = self.mongo_url.rsplit( / ,1)[1]
database = connection[db_name]
except:
print( Error: Unable to Connect )
connection = None
if connection is not None:
database.test.insert({ name : foo })
PyMongo now provides a get_default_database()
method that makes this entire exercise trivial:
from pymongo import MongoClient
client = MongoClient(os.environ[ MONGOLAB_URI ])
db = client.get_default_database()
