python flask bucketlist应用程序

转载作者：太空宇宙更新时间：2023-11-04 10:10:16

我正在尝试使用教程构建一个 python flask web 应用程序，但我在实现我的 signUp 方法时遇到了问题。教程:http://code.tutsplus.com/tutorials/creating-a-web-app-from-scratch-using-python-flask-and-mysql--cms-22972

当我点击“注册”按钮时出现 500 错误:_name = Request.form['inputName']TypeError: 'cached_property' 对象没有属性 'getitem'

不确定为什么会收到 500 错误。任何帮助，将不胜感激。谢谢

下面是我的python代码:

from flask import Flask, render_template, json, Request

app = Flask(__name__)

@app.route('/main')
def main():
    return render_template('index.html')


@app.route('/showSignUp')
def showSignUp():
    return render_template('signup.html')


@app.route('/signUp',methods=['POST'])
def signUp():
    _name = Request.form['inputName']
    _email = Request.form['inputEmail']
    _password = Request.form['inputPassword']

    if _name and _email and _password:
        return json.dumps({'html':'<span>All fields good !!</span>'})
    else:
        return json.dumps({'html:':'<span>Enter the required fields</span>'})



if __name__ == "__main__":
    app.run(debug=True)

这是 javascript ajax 代码:

$(function () {
    $('#btnSignUp').click(function () {
        $.ajax({
            url: '/signUp',
            data: $('form').serialize(),
            type: 'POST',
            success: function(response) {
                console.log(response);
            },
            error: function(error) {
                console.log(error);
            }
        });
    });
});

这里是signup.html

最佳答案

我最近在实现的时候也遇到了同样的问题。

如下更改 app.py 中的注册代码，包括导入。

from flask import Flask, render_template, json, request

def signUp():
    _name = request.form['inputName']
    _email = request.form['inputEmail']
    _password = request.form['inputPassword']

注意:应该是request 不是Request

发生此错误是因为 Request 是 Flask 用来表示传入请求的类；然而，这不是请求本身。相反，Flask 将当前请求( Request 类的一个实例)存储在 request 变量中。
