Python重定向(有延迟) [英] Python redirect (with delay)

问题描述

所以我在烧瓶上运行了这个python页面.直到我想要重定向之前，它都可以正常工作.

So I have this python page running on flask. It works fine until I want to have a redirect.

@app.route("/last_visit")
def check_last_watered():
    templateData = template(text = water.get_last_watered())
    return render_template('main.html', **templateData)
    return redirect(url_for('new_page')) #with a delay here of 3 secs

该站点工作正常，但无法重定向，而且我不知道如何延迟整个过程.想法...请:-)

The site works fine, but does not redirect and I wouldn't know how to delay the whole thing. Ideas... Please :-)

推荐答案

好吧，您的函数只会返回渲染的模板，而不会到达重定向语句.如果要显示页面，然后在延迟后执行重定向，请在模板中使用javascript重定向:

Well, your function just returns a rendered template and never reaches the redirect statement. If you want to show a page AND then do a redirect after a delay, use a javascript redirect in your template:

@app.route("/last_visit")
def check_last_watered():
    templateData = template(text = water.get_last_watered())
    templateData['redirect_url'] = url_for('new_page')
    return render_template('main.html', **templateData)

然后在您的 main.html 中:

<script>
    setTimeout(function(){
        window.location.href = '{{redirect_url}}';
    }, 2000);
</script>
