Python，烧瓶方法不允许

Question

我目前正在学习python，并且正在尝试编写一个应用程序。我已经完成了基础知识。我遵循了一个有用的教程，但却陷入了困境。我的理解是百分百的，所以任何帮助和推理都很棒。

我在尝试提交表单时遇到方法不允许的错误。我会发布下面的代码，希望有人可以提供帮助。

new_action.py

{% extends "base.html" %} 

{% block content %} 
    <h2>New Action Request</h2> 
    {% include 'flash.html' %} 
    <div class="well"> 
     <form class="form-horizontal" action="" method="post" name="post"> 
      {{ form.hidden_tag() }} 
      <div class="control-group{% if form.errors %} error{% endif %}"> 
       <label class="pull-right" for="post">Date: {{ 
        datetime.date(datetime.utcnow()) }}</label> 

       <div class="controls"> 
        {{form.timestamp}} 
       </div> 



       <label class="control-label" for="post">Raised By:</label> 

       <div class="controls"> 
        {{ form.raised_by }} 
        {% for error in form.errors.post %} 
         <span class="help-inline">[{{ error }}]</span><br> 
        {% endfor %} 
       </div> 
       <br/> 

       <label class="control-label" for="post">Source:</label> 

       <div class="controls">

Views.py

    form = ActionRequestForm() 
    if request.method == 'POST':

     #actionrequest = ActionRequest(id = form.id.data, category = form.category.data) 


     '''post = Post(body=form.post.data, timestamp=datetime.utcnow(), 
       author=g.user) 
     db.session.add(post) 
     db.session.commit() 
     flash('Your post is now live!')''' 

    return render_template('new_action.html', 
          user = user, 
          form = form, 
          datetime = datetime 
          ) 

Answer 1

表单正在尝试将数据发布到服务器。这是一个HTTP POST请求。您可以在视图中定义GET和SET方法。你需要在那里使用POST。

@app.route('/new_action', methods=['GET', 'POST']) # Changed SET to POST here 
@login_required 
def new_action(): 
    # ... what ever... 

对于HTTP，您应该通过RFC。没有SET方法。

Answer 2

@app.route('/new_action', methods=['GET', 'SET']) 

这行代码是只允许 “GET” 和 “SET” 的方法，而你正在试图“POST “到那条路。
