我得到了一个简单的flask服务器，管理登录页面。网页工作正常：登录，注销，注册等登录页面后，有一个“home.html”页面3图像。我试图做的是通过点击图像打开第二个网页。我试图加载的页面被称为“output.html”，它是在文件夹“templates”
文件夹结构：

• webserver
• 例如
• 网站
• 图像
• 静态
• 模板
• base.html
• home.html
• login.html
• main.html
• output.html
• sign_up.html
  *init.py
• auth.py
• models.py

Flask脚本：

from flask import Flask, render_template, url_for, redirect, send_from_directory, request
from flask_login import UserMixin, login_user, LoginManager, login_required, logout_user, current_user
from flask_wtf import FlaskForm
from wtforms import StringField, PasswordField, SubmitField
from wtforms.validators import InputRequired, Length, ValidationError
app = create_app()
#app = Flask(__name__, template_folder='templates')
app.config['SECRET_KEY'] = 'thisisasecretkey'
login_manager = LoginManager()
login_manager.init_app(app)
login_manager.login_view = 'login'
class RegisterForm(FlaskForm):
    username = StringField(validators=[
                           InputRequired(), Length(min=4, max=20)], render_kw={"placeholder": "Username"})
    password = PasswordField(validators=[
                             InputRequired(), Length(min=8, max=20)], render_kw={"placeholder": "Password"})
    submit = SubmitField('Register')
    
class LoginForm(FlaskForm):
    username = StringField(validators=[
                           InputRequired(), Length(min=4, max=20)], render_kw={"placeholder": "Username"})
    password = PasswordField(validators=[
                             InputRequired(), Length(min=8, max=20)], render_kw={"placeholder": "Password"})
    submit = SubmitField('Login')
#@app.route("/images/<path:filename>")
#def serve_image(filename):
#    return send_from_directory("images", filename)
@app.route('/')
def index():
    return render_template('home.html')
@app.route('/output', methods=['GET', 'POST'])
def output():
    return render_template('output.html')
@app.route('/login', methods=['GET', 'POST'])
def login():
    form = LoginForm()
    return render_template('login.html', form=form)
@app.route('/dashboard', methods=['GET', 'POST'])
@login_required
def dashboard():
    return render_template('dashboard.html')
@app.route('/logout', methods=['GET', 'POST'])
@login_required
def logout():
    logout_user()
    return redirect(url_for('login'))
@app.route('/register', methods=['GET', 'POST'])
def register():
    form = RegisterForm()
    return render_template('register.html', form=form)
if __name__ == '__main__':
    #app.run()
    app.run()

HTML端：

<div id="Ohm" class="tabcontent">
    <h3>Escolha um dos três circuitos</h3>
    <p>Clique OK para seguir</p>
    <div>
      <img 
        src="../images/circuit_R1.png" 
        width="30%" 
        height="auto"

        class="responsive" 
        onclick="redirecionarPaginaEAcionar('10010101', '/output')" 
        style="cursor: pointer;" >

 <script>
    function accionarReles(parametro)
      {
     (...)
    }
    
    function redirecionarPaginaEAcionar(parametro, url) {
      accionarReles(parametro); // Chama a função accionarReles com o parâmetro especificado
      window.location.href = url; // Redireciona para a URL especificada
    }
      
  </script>

所以，在我运行服务器并登录后，脚本调用home.html。当点击图像时，另一个html页面应该打开：output.html。然而，由于程序是我得到一个404错误页面找不到。
但是，如果我将输出替换为登录，这是同一个文件夹中的页面，一切都是正确的。
我找不到错误/错误，我不能打开另一个页面，除非是“login.html”，即使我把它移到“模板”之外，所以，我需要一些帮助来找到错误
