jinja2.exceptions.TemplateSyntaxError: expected token ',', got 'string' and TypeError: 'function' object is not subscriptable

Question

我尝试运行/homepage

@app.route('/')
def index():   
    return redirect(url_for(homepage))


@app.route('/homepage')
def homepage():
    return render_template('fullcalendar.html')

遇到错误：

TypeError: 'function' object is not subscriptable

当我在地址栏 127.0.0.1:5000/homepage 中写入时出现此错误：

  File "/home/pc/shudleApp1/env/lib/python3.6/site-packages/flask/helpers.py", line 318, in url_for
if endpoint[:1] == ".":

TypeError: 'function' object is not subscriptable

fullcalendar.html

<link href="{{ url_for('static', filename=css/fullcalendar.css') }}"/>
<link href="{{ url_for('static', filename= css/fullcalendar.print.css') }}" />
<script src="{{ url_for('static', filename=js/jquery-1.10.2.js' }}"></script>
<script src="{{ url_for('static', filename=js/jquery-ui.custom.min.js') }}"></script>
<script src="{{ url_for('static', filename=js/fullcalendar.js') }}"></script>
<script>

Answer 1

在 redirect(url_for(homepage)) 中，您将传递给 url_for homepage，这是您的函数而不是您的主页端点。

你应该通过 '/homepage'
