不允许使用Flask 405方法 [英] Flask 405 Method Not Allowed

问题描述

单击"subimit"按钮后，我遇到了标题中的问题，当我将路由从应用程序分离到视图时，当我进入localhost:5000/register/时，问题开始显示，但是当我填写表格并单击提交"时我有问题405

after click subimit button I have problem like in title, the problem start showing when I separated routes from app to views, when I go to localhost:5000/register/ all is good but when I fill the form and click submit then I have problem 405

app.py

from flask import Flask,render_template,request,redirect,abort
app = Flask(__name__)
import views

app.add_url_rule('/', view_func=views.index)
app.add_url_rule('/login/', view_func=views.login)
app.add_url_rule('/register/', view_func=views.register)

if __name__ == '__main__':
    app.run(debug=True)

views.py

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

@app.route('/register/', methods=["GET","POST"])
def register():
    if request.method == "POST":
        req = request.form
        email = req.get("email")
        password = req["password"]
        phonenumber = request.form["phonenumber"]
        if email == "" or password == "" or phonenumber=="":
            feedback="Please fill the form"
            alert = "fail"
        else:
            feedback="Account created!"
            alert = "good"
        return render_template('register.html',feedback=feedback,alert=alert)
    return render_template('register.html')

@app.route('/')
def index():
    print("CIAO")
    return render_template('base.html')

和表格

<form class="" method="POST" action="{{ url_for('register') }}">
    <input type="email" name="email" placeholder="Email">
    <input type="password" name="password" placeholder="password" minlength="8">
    <input type="tel" name="phonenumber" placeholder="Numer Telefonu" minlength="8" maxlength="9">
    <input type="submit" name="submit">
</form>

推荐答案

Flask找不到/register/端点的POST方法处理程序.您正在混合 add_url_rule 和 @route .如果您想要可插入的视图，则只需要前者即可.

Flask is not finding the POST method handler for the /register/ endpoint. You're mixing add_url_rule and @route. You just need the former if you want pluggable views.

我建议在这里使用MethodView方法.每个模板都有一个单独的类，并在其中定义 get()和 post()方法.

I would recommend using the MethodView approach here. Have a separate class for each template and define the get() and post() methods within that.

app.py:

from flask import Flask
from views import Register, Login, Index

app = Flask(__name__)

app.add_url_rule('/', view_func=Index.as_view("index"))
app.add_url_rule('/login/', view_func=Login.as_view("login"))
app.add_url_rule('/register/', view_func=Register.as_view("register"))

if __name__ == '__main__':
    app.run(debug=True)

views.py:

from flask import Flask,render_template,request,redirect,abort
from flask.views import MethodView


class Register(MethodView):
    def get(self):
        return render_template('register.html')

    def post(self):
        req = request.form
        email = req.get("email")
        password = req["password"]
        phonenumber = request.form["phonenumber"]
        if email == "" or password == "" or phonenumber == "":
            feedback = "Please fill the form"
            alert = "fail"
        else:
            feedback = "Account created!"
            alert = "good"
        return render_template('register.html', feedback=feedback, alert=alert)


class Index(MethodView):
    def get(self):
        print("CIAO")
        return render_template('index.html')


class Login(MethodView):
    def get(self):
        return render_template('login.html')
