我正在制作一个非常简单的策划wxApp.

我已经安装了Python 2.7.9和wxPython 3.0.2

这是我的代码:

import wx
import wx.lib.plot as plot

class Pantalla(wx.Frame):
    def __init__(self):
        app = wx.App()
        self.frame1 = wx.Frame(None, title = "GRAFICADOR", id = -1, size=(500,500))
        self.panel1 = wx.Panel(self.frame1)
        self.panel1.SetBackgroundColour("white")
        plotter = plot.PlotCanvas(self.panel1, id=-1, pos = wx.Point(-1,-1), size = wx.Size(-1,-1), style = 0, name= 'plotCanvas')

        data = [(1,2), (2,3), (4,6)]
        line = plot.PolyLine(data, colour='red', width = 1)
        gc = plot.PlotGraphics([line], 'Line', 'Eje x', 'Eje y')
        plotter.Draw(gc, xAxis = (0,15), yAxis=(0,15))
        self.frame1.Show(True)
        app.MainLoop()

t = Pantalla()

但是,每当我测试它时,它都会抛出这个错误:

Traceback (most …

我正在使用node.js和hapi.js开发Restful API.我正在尝试记录请求我的一条路线的客户端的IP.

这是我目前的代码:

function(request, reply){
    var ip = request.headers['x-forwarded-for'] || request.connection.remoteAddress;
    console.log('IP: ' + ip);

    //more code...
}

但是当我查看我的日志时,ip是未定义的.我怎样才能解决我的问题？
