如何解决pymongo pymongo.errors.ServerSelectionTimeoutError:hour must be in 0..23, Timeout: 30s, Topology Description:

我对 mongo db 很陌生。尝试仅在本地主机上使用 find 方法进行简单的 mongo db 提取操作。 Mongo 在所有默认设置下运行。使用 sdsveicoli.Select() 和 python 3.7 包。我不明白我到底出了什么问题。分享代码如下。

场景 #1

pymongo version 3.11.3

这给了我下面的输出

from pymongo import MongoClient
con = MongoClient()
# con = MongoClient(host='localhost',port=27017) #tried this way also
print(con)
db = con.mydb
print(db)
collection = db.VA_collection
print(collection)
found = collection.find({'online':True})  # find returns all entries
print(found)
for i in found:
    print(i)

我的实际目标是在我使用 MongoClient(host=['localhost:27017'],document_class=dict,tz_aware=False,connect=True) Database(MongoClient(host=['localhost:27017'],connect=True),'mydb') Collection(Database(MongoClient(host=['localhost:27017'],'mydb'),'VA_collection') <pymongo.cursor.Cursor object at 0x000001D368534160> Traceback (most recent call last): File "C:/Users/PycharmProjects/flask_app_stuff/1_ mongo_restful/mongodb_connection.py",line 11,in <module> for i in found: File "C:\Users\PycharmProjects\flask_app_stuff\.venv\lib\site-packages\pymongo\cursor.py",line 1207,in next if len(self.__data) or self._refresh(): File "C:\Users\PycharmProjects\flask_app_stuff\.venv\lib\site-packages\pymongo\cursor.py",line 1100,in _refresh self.__session = self.__collection.database.client._ensure_session() File "C:\Users\PycharmProjects\flask_app_stuff\.venv\lib\site-packages\pymongo\mongo_client.py",line 1816,in _ensure_session return self.__start_session(True,causal_consistency=False) File "C:\Users\PycharmProjects\flask_app_stuff\.venv\lib\site-packages\pymongo\mongo_client.py",line 1766,in __start_session server_session = self._get_server_session() File "C:\Users\PycharmProjects\flask_app_stuff\.venv\lib\site-packages\pymongo\mongo_client.py",line 1802,in _get_server_session return self._topology.get_server_session() File "C:\Users\PycharmProjects\flask_app_stuff\.venv\lib\site-packages\pymongo\topology.py",line 488,in get_server_session None) File "C:\Users\PycharmProjects\flask_app_stuff\.venv\lib\site-packages\pymongo\topology.py",line 217,in _select_servers_loop (self._error_message(selector),timeout,self.description)) pymongo.errors.ServerSelectionTimeoutError: hour must be in 0..23,Timeout: 30s,Topology Description: <TopologyDescription id: 60804696a4bda0d1ee4db3f9,topology_type: Single,servers: [<ServerDescription ('localhost',27017) server_type: UnkNown,rtt: None,error=InvalidBSON('hour must be in 0..23')>]> Process finished with exit code 1 的地方构建 flask version 1.1.2 API，但这也会给我同样的错误，所以我尝试先构建基本的 API。代码如下

场景 #2

Flask-PyMongo version 2.3.0

错误日志如下

from flask import Flask,render_template
from flask_pymongo import PyMongo


app = Flask(__name__)
app.config["MONGO_URI"] = "mongodb://localhost:27017/mydb"
mongo = PyMongo(app)
print(mongo.db)


@app.route("/")
def home_page():
    online_users = mongo.db.VA_collection.find_one({"online": True})
    for k in online_users:
        print(k)
    return render_template("index.html",online_users=online_users)


if __name__ == "__main__":
    app.run(debug=True)

场景 #1 简单 MongoClient 我的观察是，当我尝试使用简单的 mongoclient 构造函数连接 db 时给了我这个输出 Database(MongoClient(host=['localhost:27017'],connect=False),'mydb') pymongo.errors.ServerSelectionTimeoutError: hour must be in 0..23,Topology Description: <TopologyDescription id: 6080490c1fe900cc22d6b873,error=InvalidBSON('hour must be in 0..23')>]> where connect is True

场景 #2 Flask 应用 当我使用flask-pymongo时，它的数据库连接构造函数给出了 Database(MongoClient(host=['localhost:27017'],connect=True) where connect is Flase

我不明白这是什么意思，但认为它可能会带来一些帮助。提前致谢，任何帮助将不胜感激。如果需要任何额外的细节，请告诉我
