Question

我正在开发一个烧瓶注册表，我收到一个错误：

error 405 method not found.

代码：

import os
# Flask
from flask import Flask, request, session, g, redirect, url_for, abort, \
     render_template, flash, Markup, send_from_directory, escape
from werkzeug import secure_filename

from cultura import app

# My app
from include import User

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

@app.route('/registrazione', methods=['POST']) 
def registration():
    if request.method == 'POST':
        username= request.form.username.data
        return render_template('registration.html', username=username)
    else :
        return render_template('registration.html')

registration.html：

<html>
<head> <title>Form di registrazione </title>
 </head> 

    <body>
    {{ username }}
    <form id='registration' action='/registrazione' method='post'>
    <fieldset >
    <legend>Registrazione utente</legend>
    <input type='hidden' name='submitted' id='submitted' value='1'/>
    <label for='name' >Nome: </label> 
    <input type='text' name='name' id='name' maxlength="50" /> <br>
    <label for='email' >Indirizzo mail:</label>
    <input type='text' name='email' id='email' maxlength="50" />
     <br>
    <label for='username' >UserName*:</label>
    <input type='text' name='username' id='username' maxlength="50" />
     <br>
    <label for='password' >Password*:</label>
    <input type='password' name='password' id='password' maxlength="50" />
    <br>
    <input type='submit' name='Submit' value='Submit' />

    </fieldset>
    </form>
    </body>
    </html>

当我访问localhost:5000/registrazione时，收到错误消息。我做错了什么？

Answer 1

这是因为您在定义路线时只允许POST请求。

当您在浏览器中访问/registrazione时，它会首先执行GET请求。只有在您提交表单后，您的浏览器才会执行POST。因此，对于像您这样的自我提交表单，您需要同时处理这两种形式。

使用

@app.route('/registrazione', methods=['GET', 'POST'])

应该有用。

使用带有JQuery，Ajax和json的wsgi的烧瓶应用示例：

activecalls.py

from flask import Flask, jsonify

application = Flask(__name__, static_url_path='')

@application.route('/')
def activecalls():
    return application.send_static_file('activecalls/active_calls_map.html')

@application.route('/_getData', methods=['GET', 'POST'])
def getData():
    #hit the data, package it, put it into json.
    #ajax would have to hit this every so often to get latest data.
    arr = {}
    arr["blah"] = []
    arr["blah"].append("stuff");

    return jsonify(response=arr)


if __name__ == '__main__':
    application.run()

Javascript json，/ static / activecalls / active_calls_map.html：

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js">
</script>

<script>
$.ajax({
    //url : "http://dev.consumerunited.com/wsgi/activecalls.py/_getData",
    url : "activecalls.py/_getData",
    type: "POST",
    data : formData,
    datatype : "jsonp",
    success: function(data, textStatus, jqXHR)
    {
        //data - response from server
         alert("'" + data.response.blah + "'");
    },
    error: function (jqXHR, textStatus, errorThrown)
    {
         alert("error: " + errorThrown);

    }
});
</script>

当你运行它。警告框打印：“stuff”。

Answer 3

仅供现在阅读的人。您必须先呈现/ registrazione，因为您可以访问表单数据。只是写。

@app.route("/registrazione")
    def render_registrazione() -> "html":
        return render_template("registrazione.html")

在定义def registration（）之前。顺序是关键。您无法在偶数可用之前访问数据。这是我对问题的理解。

Answer 4

更改方法注册名称

@app.route('/registrazione', methods=['POST']) 
def registrazione(): 
    if request.method == 'POST':
       username= request.form.username.data
       return render_template('registration.html', username=username)
   else :
       return render_template('registration.html')

方法不允许烧瓶错误405
