我是python的初学者。我正在尝试从我的 python 烧瓶应用程序连接到 Mongo DB 服务器。但是由于遇到以下问题，我无法运行该应用程序。

from flask import Flask, render_template
from flask_pymongo import PyMongo
from pymongo import MongoClient # Database connector

app=Flask(__name__)

app.config["MONGO_DBNAME"]="connect_to_pymon"
app.config["MONGO_URI"]="mongodb://mongo_test:mongo_test@123@ds129821.mlab.com:29821/connect_to_pymon"
mongo = PyMongo(app)

@app.route("/add")
def add():

    user = mongo.db.users
    user.insert[{"name":"kishor"}]
    return "users added!"

if __name__=='__main__':
    app.run(debug=True, port=8080)

这是我的源代码。当我执行此操作时，我收到以下错误，我无法跟踪它。

Traceback (most recent call last):
  File "C:/Users/kravi/PycharmProjects/GitUploadTest/mongoTest.py", line 9, in <module>
    mongo = PyMongo(app)

    "RFC 3986, use %s()." % quote_fn)
pymongo.errors.InvalidURI: Username and password must be escaped according to RFC 3986, use urllib.parse.quote_plus().

Process finished with exit code 1

注意：我还没有在我的电脑上安装 mongoDb。我正在使用 mongo db 作为服务

您可以使用 PyMongo 连接到您的数据库，如下所示：

from pymongo import MongoClient

client = MongoClient("mongodb://mongo_test:mongo_test@123@ds129821.mlab.com:29821/connect_to_pymon")

db = client["dbname"] # connect_to_pymon in your case

我知道在密码中使用像“@”这样的特殊字符是没有意义的，因为我们必须配置具有特定格式的 mongo URI，其中包含符号 @。我更改了数据库密码并尝试了，之后它工作了。！
