javascript - Flask + Heroku：H12 请求超时错误

Question

我有一个 Heroku 应用程序来运行 Scrapy Spider。启动后，我收到错误 H12。如何解决？

查询：

$.post('/wellness', {'specialty': specialty, 'state': state, 'city': city}, (res) => { 
      $(location).attr('href', 'http://127.0.0.1:5000/wellness')
    });

烧瓶：

if request.method == 'POST':
    specialty = request.form.getlist('specialty[]')
    state = request.form.getlist('state[]')
    city = request.form.getlist('city[]')

    settings = ''
    with open(file_json, 'r') as f:
        for line in f.read():
            settings += line

    settings = json.loads(settings)
    settings['specialty'] = specialty
    settings['state'] = state
    settings['city'] = city

    with open(file_json, 'w') as f:
        f.write(json.dumps(settings, indent=4))

    process = subprocess.Popen('python spiders/' + file_py, shell=True)
    process.wait()

return render_template(file_html)
