如何使用Python Flask将数据从html发送到MongoDB

-1

我正在尝试开发一个Web应用程序，我想在其中上传多个CSV文件并将它们传输到MongoDB。我用Python Flask来开发应用程序。如何使用Python Flask将数据从html发送到MongoDB

我已经创建了一个示例文件来测试几个概念，其中我已经实现了直到从本地桌面浏览文件。但是，我想上传相同的文件并将其传输到MongoDB。

你能帮我实现吗？我无法弄清楚如何实现这一目标。

瓶：

from flask import Flask, render_template, url_for, request, session, redirect 
from flask.ext.pymongo import PyMongo 
import bcrypt 

app = Flask(__name__) 

app.config['MONGO_DBNAME'] = 'mongologinexample' 
app.config['MONGO_URI'] = 'mongodb://Anvesha1124:[email protected]:57509/connect_to_mongo1124' 

mongo = PyMongo(app) 



@app.route('/login')

     return 'You are logged in as ' + session['username']""" 

    return render_template('header.html') 


@app.route('/login', methods=['POST'])

    users = mongo.db.users 
    login_user = users.find_one({'name' : request.form['username']}) 

    if login_user: 
     if bcrypt.hashpw(request.form['pass'].encode('utf-8'), login_user['password'].encode('utf-8')) == login_user['password'].encode('utf-8'): 
      session['username'] = request.form['username'] 
      return redirect(url_for('header')) 

    return 'Invalid username/password combination'

你似乎并没有把发布任何瓶代码在所有。 –

也添加了Python代码。请检查 –

您可以使用：Flask-PyMongo

例如：

@app.route('/uploads/<path:filename>', methods=['POST']) 
def save_upload(filename): 
    mongo.save_file(filename, request.files['file']) 
    return redirect(url_for('get_upload', filename=filename))
