下面的代碼需要html註冊表單數據，並且假設推送到mongoDB。python無法將數據推送到mongoDB
from flask import Flask
from flask import request
from flask import render_template, flash,redirect,url_for,session,logging
from flask_pymongo import PyMongo
from wtforms import Form, StringField, TextAreaField,PasswordField,validators
from passlib.hash import sha256_crypt
import bcrypt
app = Flask(__name__)
app.config['MONGO_NAME'] = 'amitesh_DB'
app.config['MONGO_HOST'] = 'mongodb://localhost:27017'
mongo = PyMongo(app)
@app.route('/')
def index():
if 'username' in session:
return 'you are logged in as' + session['username'] # gives the message and the name of the username that is logged in that session.
return render_template('index.html')
@app.route('/login')
def login():
#users = mongo.db.users
# users.find_one({'name' : request.form['username']})
return ''
#we are checking if the username that we are registering doesn't exist, if it does, it will return index.html
@app.route('/register', methods=['POST','GET'])
def register():
if request.method == 'POST':
users = mongo.db.users #connecting the collection called "users" in mongoDB
existing_user = users.find_one({'name':request.form['username']})# we are looking for a name in the mongoDB in the collection "users" that is a username that we are registering with.
if existing_user is None:#if the above request.form doesn't find the username with a name that we enter in the html form, then this "if" will allow the new username to register.
hashpass = bcrypt.hashpw(request.form['pass'].encode('utf-8'), bcrypt.gensalt())
users.insert({'name': request.form['username'],'password' : hashpass})
session['username'] = request.form['username']
return redirect(url_for('index'))
return 'username already exist' # means, "existing_users" wasn't none
return render_template('register1.html')
if __name__ == '__main__':
app.secret_key = 'mysecret'
app.run(debug=True)
我有以下問題::
1）雖然我剛纔提到的DB名稱，服務器地址，收藏，但我沒有看到蒙戈的數據，我蒙戈工作，並我的Python代碼可以傳達給它，作爲一個證明，下面是從蒙戈屏幕::

2）在Python代碼的一些消息，我已經使用bcrypt加密我的密碼，而密碼中插入文本提交，但它仍然是純文本。不知道我在這裏是否缺少任何東西。
