使用flask_pymongo时身份验证失败
使用flask_pymongo时身份验证失败
提问于 2016-06-21 21:03:46
我确信MONGO_URI是正确的，因为它在pymongo中工作得很好。但是当使用flask_pymongo时，它不能工作...下面是我的测试代码：
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，将给出500的响应。
OperationFailure: Authentication failed.
127.0.0.1 - - [21/Jun/2016 20:40:25] "GET / HTTP/1.1" 500 -任何帮助都将不胜感激。
更新:这是回溯：

问题是，如果使用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。您应该将配置参数分成以下几部分，以便可以指定db名称和身份验证源。
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 dbStack Overflow用户

这个问题可能很老，但我遇到了同样的问题，并找到了另一个可能适用于其他人的解决方案。
将?authSource=admin附加到MONGO_URI变量的末尾将根据管理员数据库而不是您要连接的数据库来验证您的凭据。
示例：app.config["MONGO_URI"] = "mongodb://username:password@host:port/db_name?authSource=admin"

如果您正在使用Flask-MongoEngine并使用app.config['MONGODB_*']设置mongo配置，那么您的uri将从这些变量生成，例如
app.config['MONGODB_DB'] = 'project1'
app.config['MONGODB_HOST'] = '192.168.1.35'
app.config['MONGODB_PORT'] = 12345
app.config['MONGODB_USERNAME'] = 'webapp'
app.config['MONGODB_PASSWORD'] = 'pwd123'但是，如果您需要向uri添加一些额外的参数(如查询参数authSource=admin)，则必须通过app.config['MONGODB_SETTINGS']传递mongo config
app.config['MONGODB_SETTINGS'] = {
'connect': False,
'host': 'mongodb://webapp:pwd123@192.168.1.35:12345/project1?authSource=admin'
