我有一个 Python 代码。import cx_Oracleimport refrom flask import Flask, render_template, request, url_for, redirectapp = 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：<!DOCTYPE html><html><head> <!-- Latest compiled and minified CSS --> <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" integrity="sha384-BVYiiSIFeK1dGmJRAkycuHAHRg32OmUcww7on3RYdg4Va+PmSTsz/K68vbdEjh4u" crossorigin="anonymous"> <!-- Optional theme --> <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap-theme.min.css" integrity="sha384-rHyoN1iRsVXV4nD0JutlnGaslCJuC7uwjduW9SVrLvRYooPp2bWYgmgJQIXwl/Sp" crossorigin="anonymous">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？

在这里，您将表单数据发布到/post_data并将其重定向到，/add因此已编辑的函数将无法访问包含表单数据的请求对象。所以只需将表单操作更改/add为使其正常工作。
