-------------------------------Mongodb 连接---------------------------
1. 连接MongoDB
1）无密码连接
def __init__(self):
conn = MongoClient(host=MOGODB_HOST, port=MOGODB_PORT)
db = conn.test # admin 这个数据库要用于登陆不验证，一般不用
self.collection = db.datasource # 没有datasource会自动创建
2）有密码登陆验证连接
def __init__(self):
conn = MongoClient(host=MONGODB_HOST, port=MONGODB_PORT)
db = conn.admin
db.authenticate(name=MONGODB_USER, password=MONGODB_PASSWORD)
testdb = conn.testdb
self.collection = testdb.datasources

只能单条检测，将注释去掉即可，数据库文件自己建立即可
