Ubuntu22.04下Flask Python3调用MongoDB查询时遇Flask错误求助

home.py头部代码 #

from flask import Flask, render_template, url_for, request, redirect  
from kafka import KafkaConsumer
from kafka import KafkaProducer
import os
import time
import json
import pymongo

app = Flask(__name__)
app.secret_key = 'any random string'

myclient = pymongo.MongoClient("mongodb://localhost:27017/")
user_db = myclient["authentication"]
user_table = user_db["user_info"]

相关代码片段 #

print("0")
print(req)
print(type(user_table))
query = user_table.find({'uid':req['uid']})     
print(query)
print('1')

控制台输出 #

0
{'uid': '', 'email': '', 'password': ''}
<class 'pymongo.collection.Collection'>
<pymongo.cursor.Cursor object at 0x7f62f684f700>
1

输出完成后出现Flask错误，当前卡在教程第二章40分04秒，请求协助排查解决。
