使用flask_pymongo时身份验证失败 [英] Authentication failed when using flask_pymongo

问题描述

我确定MONGO_URI是正确的，因为它在pymongo中运行良好.但是当使用flask_pymongo时，它不起作用...这是我的测试代码:

I'm sure that the MONGO_URI is correct because it works well in pymongo. but when using flask_pymongo, it doesn't work... here is my test code:

from flask import Flask
from flask_pymongo import PyMongo
app = Flask(__name__)

app.config['MONGO_URI'] ='mongodb://root:aaa2016@localhost:27017/mongo_test'
mongo = PyMongo(app, config_prefix='MONGO')


@app.route('/')
def hello_world():
    mongo.db.user.insert({'username': "aaa"})
    return 'Hello World!'


if __name__ == '__main__':
    app.run()

运行它并访问127.0.0.1:5000，给出的响应为500.

run it and visit 127.0.0.1:5000, a response of 500 is given..

OperationFailure: Authentication failed.
127.0.0.1 - - [21/Jun/2016 20:40:25] "GET / HTTP/1.1" 500 -

任何帮助将不胜感激.

推荐答案

问题是，如果您使用 MONGO_URI 配置参数，则pymongo会尝试根据字符串中包含的数据库名称进行身份验证.您应该将config参数分解为以下内容，以便您可以指定数据库名称和身份验证来源.

The problem is if you use the MONGO_URI config parameter then pymongo attempts to authenticate against the db name included in the string. You should break up the config parameters into the following so you can specify a db name and an auth source.

app.config['MONGO_HOST'] = 'localhost'
app.config['MONGO_PORT'] = '27017'
app.config['MONGO_DBNAME'] = 'mongo_test'
app.config['MONGO_USERNAME'] = 'root'
app.config['MONGO_PASSWORD'] = 'aaa2016'
app.config['MONGO_AUTH_SOURCE'] = 'admin' . # root user is typically defined in admin db
