所请求的网址不允许使用方法

Question

from flask import *
from flask_restful import *
import sqlite3
import database


@app.route('/admin')
def admin():
    """ hanldes the admin page for user entry """

    db = database.database()
    db.create()
    db.table('admin')
    #data = db.print_database('admin')
    #return render_template ("mylogin.html", input = 'admin', dbs = data.fetchall())
    return render_template ("mylogin.html", input = 'admin')

@app.route('/admin', methods = ["POST"])
def admin_post():
    """ hanldes the admin page for user entry """
    print "handling post"
    return request.form['text']

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

HTML CODE：我没有在此处发布完整的代码，因为它没有偏离我所面临的问题。 我可以打开/ admin页面，当我输入内容时，出现错误“请求的URL不允许使用方法”

<h2>welcome admin</h2>
<form action="." method ="POST">
    hello admin
    <input type = "text" name = "text">
    <input type = "submit" name ="my-form" value = "Send">
</form>

Answer 1

将您的html更改为此：

<h2>welcome admin</h2>
<form action="{{ url_for('admin_post') }}" method ="POST">
   <input type = "text" name = "text">
   <input type = "submit" name ="my-form" value = "Send">
</form>

您基本上要做的就是将表单发送到仅接受GET请求的admin函数。

您需要将表单发布到接受POST请求的admin_post函数。
