Python Flask注册表表单-在服务器上找不到请求的URL

Question

我一直从中得到：

“404未找到-未找到”。

在服务器上找不到请求的URL。如果您手动输入URL，请检查拼写，然后再试一次。我肯定有一个愚蠢的错误，我是python新手，我花了几个小时试图理解这个问题。

我的代码：

@app.route('/register', methods=['GET', 'POST'])
def register():
    form = RegisterForm(request.form)
    if request.method =='POST' and form.validate():
        name = form.name.data
        lastname = form.lastname.data
        email = form.email.data

        # Create DictCursor
        cur = mysql.connection.cursor()

        # Execute query
        cur.execute("INSERT INTO users(name, lastname, email) VALUES(%s, %s, %s, %s)", (name, lastname, email))

        # Commit to DB
        mysql.connection.commit()

        # Close connection
        cur.close()

        flash('You are now subscribed to the podcast channel', 'success')

        redirect(url_for('index'))
    return render_template('register.html', form=form)

注册格式为：

{% extends 'layout.html' %}

{% block body %}
    <h1>Subscribe</h1>
    {% from "includes/_formhelpers.html" import render_field %}
    <form method="POST" action=="">
      <div class="form-group">
        {{render_field(form.name, class_="form-control")}}
      </div>
      <div class="form-group">
        {{render_field(form.lastname, class_="form-control")}}
      </div>
      <div class="form-group">
        {{render_field(form.email, class_="form-control")}}
      </div>
      <div class="form-group">
        {{render_field(form.confirm, class_="form-control")}}
      </div>
      <p><input type="submit" class="btn btn-primary" value="Submit"></p>
    </form>
{% endblock %}

我确认我可以直接联系http://127.0.0.1:5000/register.

在调试模式下运行应用程序，这就是我得到的：

• 使用stat重新启动
• 调试器处于活动状态

很抱歉再次提出一个非常老的问题，但您需要将表单操作指向“/注册”。这使得表单直接将数据传送到“/注册”路径，并执行在那里处理的指令。

<form method="POST" action="/register">
