Python，不允许使用 Flask 方法

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。我遵循了一个很有帮助但被卡住了的教程。我的理解是 100% 达到标准，所以任何帮助和背后的推理都会很棒。

我在尝试提交表单时收到“方法不允许”错误。我将 post 下面的代码，希望有人能提供帮助。

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">

Answer 1

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

这行代码只允许 "GET" 和 "SET" 方法，而您正试图 "POST" 到那条路线。

Answer 2

您的表单正在尝试 POST 向服务器发送数据。这是一个 HTTP POST 请求。您在视图中定义 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...

您应该通过此 RFC 了解 HTTP。没有 SET 方法。
