< / fieldset>
< / form>
< / body>
< / html>
当我访问 localhost：5000 / registrazione ，我收到错误。我在做什么错了？
解决方案
这是因为您在定义路由时只允许POST请求。
$ b
当您在浏览器中访问 / registrazione 时，它将首先执行GET请求。只有您提交表单，浏览器才会执行POST。因此，对于像你这样的自我提交表单，你需要同时处理这两个。
使用
@ app.route（'/ registrazione'，methods = ['GET'，'POST']）
应该有效。
I am developing a flask registration form, and I receive an error:
error 405 method not found.
Code:
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>
when I visit localhost:5000/registrazione, I receive the error. What am I doing wrong?
解决方案
This is because you only allow POST requests when defining your route.
When you visit /registrazione in your browser, it will do a GET request first. Only once you submit the form your browser will do a POST. So for a self-submitting form like yours, you need to handle both.
Using
@app.route('/registrazione', methods=['GET', 'POST'])
should work.
