我是 flask-py2neo-pyhon-neo4j 的新手，所以我需要一些帮助我有以下问题。我运行/执行的主要 .py 是 views.py 我有另一个 py 脚本，我在其中提交了一些 form_data.html> 更清楚 views.py --calls-->app.py--calls--> form_action.html & form_submit.html 我怎样才能实现这个序列？ flask-python 代码：views.py

@app.route('/vital', methods=['GET','POST'])
def vital():
#    username = session.get('username')

    name=request.form['pname']
    sfx=request.form['psfx']
    midname=request.form['pmidname']
    bsurname=request.form['pbsurname']

#    if not name:
#        flash('You must give your post a name.')
#    elif not sfx:
#        flash('You must give your post a suffix.')
#    elif not midname:
#        flash('You must give your post a midname.')
#    elif not bsurname:
#        flash('You must give your post a bsurname.')
#    else:
#        User(session['username']).vital(name, sfx, midname, bsurname)

    return render_template('form_action.html', username=username, sfx=sfx, midname=midname, bsurname=bsurname)

app.py

from flask import Flask, render_template, request, url_for
app = Flask(__name__)

@app.route('/')
def form():
    return render_template('form_submit.html')

@app.route('/hello/', methods=['POST'])
def hello():
    name=request.form['pname']
    sfx=request.form['psfx']
    midname=request.form['pmidname']
    bsurname=request.form['pbsurname']
    return render_template('form_action.html', name=name, sfx=sfx, midname=midname, bsurname=bsurname)

if __name__ == '__main__':
    app.run()
    send_data()

【解决方案1】：

最简单的方法是在重构模板后简单地包含模板。如果不重构它们，form_submit.html 中的内容将被添加，因此页面上会有两个<html>。一个简单的重构可能是：

base.html（新文件）

<html>
    <head>
        <title>{% block page_title %}{% endblock page_title %}</title>
    <link rel=stylesheet type=text/css href="{{ url_for('static', filename='style.css') }}">    
    </head>
    <body>
        {% block page_content %}{% endblock page_content %}
    </body>
</html>

form_submit.html（重构）

<form method="post" action="{{ url_for('hello') }}">
    <label for="pname">Name:</label>
            <input type="text" name="pname" /><br />
            <label for="psfx">Suffix: </label>
    <input type="text" name="psfx" /><br />
    <label for="pmidname">Middle Name: </label>
    <input type="text" name="pmidname" /><br />
    <label for="pbsurname">Birth Surname: </label>
    <input type="text" name="pbsurname" /><br />

    <input type="submit" />
</form>

form_action.html（重构）

Tell us  about <strong>{{name}}</strong> {{bsurname}}!

form_page.html（新文件）

{% extends "base.html" %}

{% block page_content %}
   Content of form_action: <br/>
   {% include "form_action.html" %}
   <br/>
   <br/>
   Content of form_submit: <br/>
   {% include "form_submit.html" %}
{% endblock page_content %}

还请注意，您现在应该在代码中呈现“form_page.html”。

你好阿德里亚诺，我完全按照你说的做了，但是当我按下链接“你好”时，我收到错误“方法不允许请求的 URL 不允许该方法。”
把@app.route('/hello/', methods=['POST'])改成@app.route('/hello/', methods=['POST', 'GET'])

【解决方案2】：

不是，但我找到了！ :) 非常感谢你，我很感激你提供了一些时间安德里亚诺我不得不将变量从一个更改为另一个我把它改成了 hello --> vital, form_submit-->vital.html 这是代码视图.py

@app.route('/vital')
def vital():
    return render_template('vital.html')
@app.route('/result',methods = ['POST', 'GET'])
def result():
    name=request.form['pname']
    sfx=request.form['psfx']
    midname=request.form['pmidname']
    bsurname=request.form['pbsurname']

    return render_template('form_action.html', 
                    name=name, 
                    sfx=sfx, 
                    midname=midname, 
                    bsurname=bsurname
                    )

form_action.html

<!doctype html>
<html>
  <body>
<!-- <blockquote> </blockquote> kanei kai tab k new line!! -->
    <div id="content">{% block content %}
        Tell us more about <strong>{{name}}</strong> {{bsurname}}!
        <br /><br /><br /><i>You've entered: </i><br />
        <i style="margin-left: 40px">{{midname}}</i><br />
        <i style="margin-left: 40px">{{bsurname}}</i><br /><br /><br /><br /><br /><br /><br />
    {% endblock %}</div>
    </div>
  </body>
</html>

重要的.html

<html>
     <body>
        <div id="container">
            <div class="title">
                <h1>Person's Vital Information</h1>
            </div>
            <div id="content">
                <form action = "http://localhost:5000/result" method = "POST">
                    <label for="pname">Name:</label>
                    <input type="text" name="pname" /><br />
                    <label for="psfx">Suffix: </label>
                    <input type="text" name="psfx" /><br />
                    <label for="pmidname">Middle Name: </label>
                    <input type="text" name="pmidname" /><br />
                    <label for="pbsurname">Birth Surname: </label>
                    <input type="text" name="pbsurname" /><br />

                <input type="submit" />
                </form>
            </div>
            <div class="title">

            </div>
        </div>
    </body>
