如何在Vagrant上从主机访问来宾机的URL？

Question

我正在运行Flask应用程序，其基本布局为：

def run_period():
    urllib2.urlopen('http://10.0.2.15:8080/foo')

@app.route('/')
def mainpage():
    run_period()

@app.route('/foo')
def entertainment():
    # do something

我的流浪文件配置如下：

VAGRANTFILE_API_VERSION = "2"

Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|
  config.vm.provision "shell", path: "pg_config.sh"
  # config.vm.box = "hashicorp/precise32"
  config.vm.box = "ubuntu/trusty32"
  config.vm.network "forwarded_port", guest: 8000, host: 8000
  config.vm.network "forwarded_port", guest: 8080, host: 8080
  config.vm.network "forwarded_port", guest: 5000, host: 5000
end

我在我的虚拟机中执行了ifconfig以获取我在urlopen()传递的IP地址。

但我无法在我的主机（Windows）机器上打开http://10.0.2.15:8080/。
