Question

在我的代码中，有2种形式：1在登录页面上，其他在myapp页面上。当我在登录页面上按“提交”按钮时，它将直接显示keyerror'emp-name'..我将无法看到myapp.html页面。提交用户名和密码后，我想在myapp页面上发布员工代码。但是我的代码并没有发生这种情况。

app.py：

from flask import Flask, flash, redirect, render_template, request, session, abort,send_file
import os
from flask_sqlalchemy import SQLAlchemy
from sqlalchemy.orm import sessionmaker
from tabledf import *

engine = create_engine('sqlite:///tutorial.db', echo=True)
app = Flask(__name__)
@app.route('/')
def home():
    return  "Hello Employee <a href='/login'>Login</a>"

@app.route('/login')
def login():
    if not session.get('logged_in'):
        return render_template('login.html')
    else:
        return render_template('main.html')

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

   POST_USERNAME = str(request.form['username'])
   POST_PASSWORD = str(request.form['password'])

   Session = sessionmaker(bind=engine)
   s = Session()
   query = s.query(User).filter(User.username.in_([POST_USERNAME]), User.password.in_([POST_PASSWORD]) )
   result = query.first()
   if result:
       session['logged_in'] = True
       return render_template('main.html')
   else:
       flash('wrong password!')
       return render_template('login.html')
#   return home()

@app.route('/myapp', methods=['POST'])
def parse(): 
    stock = request.form['stock-name']
    function(stock)
    return render_template('download.html')

登录html：

myapp.html：

                    </div>
                  <input type="submit" value="Submit" >

            </div>
