我有一个 Python 代码。
import cx_Oracle
import re
from flask import Flask, render_template, request, url_for, redirect
app = Flask(__name__)
app.config['SECRET_KEY'] = 'd369342136ecd032f8b4a930b6bb2e0e'
@app.route('/add')
def edited():
connect = cx_Oracle.connect("********", "********", "******/XE")
cursor = connect.cursor()
cod_ed = request.form['cod_ed']
nome_ed = request.form['nome_ed']
endereco = request.form['endereco']
telefone = request.form['telefone']
cidade = request.form['cidade']
execute = """INSERT INTO editor VALUES
(:cod_ed, :nome_ed, :endereco, :telefone, :cidade)"""
cursor.execute(execute, {'cod_ed':cod_ed, 'nome_ed':nome_ed, 'endereco':endereco, 'telefone':telefone, 'cidade':cidade})
connect.commit()
@app.route('/', methods=['GET', 'POST'])
def add_data():
return render_template('forms.html')
@app.route('/post_data', methods=['GET','POST'])
def post_data():
return redirect(url_for('edited'))
if __name__ == "__main__":
app.run(host = 'localhost', port = 8000, debug=True)
和它的 html 通讯员:

总的来说,我对 Flask 和 Python 比较陌生。当我运行表单时,它们会显示出来,但是当我尝试将它们插入数据库时,我得到了这个:
werkzeug.exceptions.HTTPException.wrap.<locals>.newcls: 400 Bad Request: KeyError: 'cod_ed'
究竟是什么原因造成的,我该如何解决?
