Question

我是 Flask 的初级程序员，遇到了一个问题，但我的代码却看不到这个问题。

在登录文件中，我有一个表单，它会向 /check 发送一个请求，但我收到了一个类似的错误：The requested URL was not found on the server. If you entered the URL manually please check your spelling and try again.

我也有带有操作路径“/”的注册文件，这很有效。

代码如下：

from flask import Flask, render_template, request, url_for, redirect
from models.Data_Base import DataBase

app = Flask(__name__)

db = DataBase()

@app.route('/')
def main_page_render():
    return render_template('home.html')

@app.route('/login')
def login_page_render():
    return render_template('login.html')

@app.route('/check')
def check_page_render():
    print('{} {}'.format(request.form['user_name'],  request.form['password']))
    if request.form['user_name'] == 'admin' and request.form['password']:
        return redirect(url_for('admin_page_render'))
    elif db.verify_login(request.form['user_name'], request.form['password']) == True:
        return redirect('/fighter/{}'.format(request.form['user_name']))

@app.route('/admin')
def admin_page_render():
    return 'Admin Page'

@app.route('/fighter/<username>')
def fighter_page_render(username):
    return 'Fighter page'


@app.route('/register')
def register_page_render():
    return render_template('register.html')


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


<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>login_page</title>
</head>
<body>
    <h2>Login Page</h2>

    <form action="/check">
      <label for="user_name">User name:</label><br>
      <input type="text" id="user_name" name="user_name"><br>
      <label for="password">Password:</label><br>
      <input type="password" id="password" name="password"><br><br>
      <input type="submit" value="Submit">
    </form>

    <p>Click submit in order to get to your account</p>
</body>
</html>

解决方案可以是这样，尝试进行这些更改。

app.py
...

@app.route('/check', methods=["GET", "POST"])
def check_page_render():
     print('{} {}'.format(request.form['user_name'],  request.form['password']))
     if request.form['user_name'] == 'admin' and request.form['password']:
         return redirect(url_for('admin_page_render'))
     elif db.verify_login(request.form['user_name'], request.form['password']) == True:
         return redirect('/fighter/{}'.format(request.form['user_name']))

...

/templates/home.html

<!DOCTYPE html>
<html lang="en">
<head>
   <meta charset="UTF-8">
   <title>login_page</title>
 </head>
 <body>
    <h2>Login Page</h2>

  <form action="/check" method="POST">
  <label for="user_name">User name:</label><br>
  <input type="text" id="user_name" name="user_name"><br>
  <label for="password">Password:</label><br>
  <input type="password" id="password" name="password"><br><br>
  <input type="submit" value="Submit">
</form>

   <p>Click submit in order to get to your account</p>
</body>
</html>

尝试提交时表单请求烧瓶错误
