iOS文档说我们可以一次呈现一页或两页,具体取决于脊柱的位置或位置以及双面状态......
但是,我无法理解" UIPageViewController中究竟是什么脊柱？ "

我正在尝试使用http模块创建一个简单的服务器和一个带有node.js的简单客户端.服务器工作正常,但客户端不工作.请帮我找一下这个bug ...
服务器是:

var server = require('http').createServer();
server.on('request', function(req, res){
    res.end("hello, world");
});
server.listen(4000);

客户是:

var options = {
    host   : 'localhost',
    port   : 4000,
    method : 'GET',
    path   " '/'
};
require('http').request(options, function(res){
    console.log(require('util').inspect(res));
    res.on('data', function(data){
        console.log(data);
    });

我在不同的终端窗口中运行它们作为节点server.js和节点client.js.

我在大约10分钟后在client.js运行终端上得到以下提到的错误.

events.js:72
    throw er; // Unhandled 'error' event
          ^
Error: socket hang up
at createHangUpError (http.js:1473:15)
at Socket.socketOnEnd [as onend] (http.js:1569:23)
at Socket.g (events.js:175:14)
at Socket.EventEmitter.emit (events.js:117:20)
at _stream_readable.js:920:16
at process._tickCallback (node.js:415:13)

谢谢 !

我希望从iOS 7后台运行的应用程序向我的服务器发送一些数据(位置坐标).我正在使用NSURLSessions来实现此目的.
我对于我应该用于此目的的会话类型感到困惑:
默认会话:我们可以在后台创建和使用默认会话.如果是,它可以优雅地处理网络故障.
后台会话:我可以使用后台会话将数据作为NSData对象上传.

PS:在这两种情况下,一些代码将非常感谢处理网络故障.

我在我的服务器日志文件中找到了这些请求。我在亚马逊 EC2 上使用 nodejs。

虽然我的网站目前非常简单。无论您发送什么请求，它都会给您相同的响应。但是，这些要求真的让我害怕。我的网站甚至一点都不出名。

我的担忧是：
有人想黑我吗？
如果是，我可以对 EC2 上的 nodejs 采取哪些预防措施？

提前致谢...
