题:

是否有可能在PHP中存储类似于$ _SESSION ['somedata'] ="Hello"的会话数据？

到目前为止,这是我的代码:

创建内存存储

var MemoryStore = express.session.MemoryStore,
    sessionStore = new MemoryStore();

快速配置

app.configure(function(){
  app.set('views', __dirname + '/views');
  app.set('view engine', 'jade');
  app.use(express.bodyParser());
  app.use(express.methodOverride());
  app.use(express.cookieParser());
  app.use(express.session({
    store: sessionStore,
    secret: 'secret', 
    key: 'express.sid'}));
  app.use(require('stylus').middleware({src: __dirname + '/public'}));
  app.use(app.router);
  app.use(express.static(__dirname + '/public'));
});

解析cookie以获取握手授权的会话ID

var parseCookie = require('connect').utils.parseCookie;

io.set('authorization', function (data, accept) {
  if (data.headers.cookie) {
    data.cookie = parseCookie(data.headers.cookie);
    data.sessionID = data.cookie['express.sid'];

    sessionStore.get(data.sessionID, function (err, session) {
      if (err) 
      {
          accept(err.message, false); //Turn down the connection
      } 
      else
      {
          data.session …

是否可以在JavaScript对象中使用setTimout()？

目前动画方法调用运行一次,似乎setTimeout()没有完成它的工作.我已经设法让它工作,但是在一个非常hackish方法中,在类之外使用setTimeout.我想让动画循环成为AnimationManager类的工作.如果你能看到任何不良做法,或者我出错了......请给我一个抬头!

JavaScript的:

var AnimationManager = function(canvas)
{
    this.canvas = canvas;
    this.canvasWidth = canvas.width();
    this.canvasHeight = canvas.height();
    this.ctx = canvas.get(0).getContext('2d');
    this.running = true;

    this.start = function start(){
        this.running = true;
        this.animate();
    }

    /** Allow the animations to run */
    this.run = function run(){
        this.running = false;

    } 
    /** Stop the animations from running */    
    this.stop = function stop(){
        this.running = false;
    }

    this.animate = function animate()
    {
        if(this.running)
        {
            this.update();
            this.clear();
            this.draw();
        }
        setTimeout(this.animate, 40); //25 fps
    }

我正在尝试使用以下命令安装Node,socket.io和npm:

cd ~
sudo apt-get install libv8-2.0.3 libv8-dev libv8-dbg libssl-dev curl
wget http://nodejs.org/dist/node-v0.4.3.tar.gz
tar zxvf node-v0.4.3.tar.gz
cd node-v0.4.3
sudo ./configure && make && make install
sudo curl http://npmjs.org/install.sh | sudo sh
sudo npm install socket.io

但是脚本失败了:

sudo ./configure && make && make install

它无法在usr/local/include中创建节点目录.我正在使用sudo而且它不能正常工作...我有一种感觉,它与我从Windows安装的Ubuntu 11.04安装有关...但我可能是错的.当我去usr/local/include我没有权限做任何事情,即使我有root权限....

你知道为什么这不起作用吗？

这是完整的错误消息:

Cannot create folder '/usr/local/include/node/' (original error: [Errno 13] Permission denied: '/usr/local/include/node/')

是否可以将HTML元素传递到jade文件中,例如我希望以下内容用文本填充p元素,以及包含嵌套在p元素内的一些包含文本的代码元素.

包含字符串的JSON

var news = {
  one : {
    title : "Using JSON",
     body : "Using JSON is a great way of passing information into the jade template files."+
            "It can be looped over using jades each syntax <code>test</code>"
  },
  two : {
    title : "",
    body : ""
  }
}

路由HTTP请求

// Routes
app.get(navigation.home.uri, function(req, res){ //Home
  res.render(navigation.home.url, {
    title: navigation.home.title,
    navigation: navigation,
    news: news
  });
});

Jade文件片段,每个新闻项都有一个循环

  section#news
    - each item in news
      article(class="news")
        header
          h2 #{item.title}
        p …

如何从去:http://url:port/user?u=username到http://url:port/user/username节点服务器上使用快递框架时？

当前的JavaScript服务器端代码:

  app.get('/user', function(req, res){
    var username = req.param("u");    
    users.findOne({username : username}, function(err, result){      
      var user = {
        username : result.username,
        name : result.name,
        surname : result.surname,
        email : result.email     
      }

      res.render('user',
        {user : user}
      );
    })
  })

由于某种原因,添加控制器类对话框没有拾取电影和MovieDBContext分类.我是ASP.NET和Visual Studio 2010的新手,我应该为这些类在这里展示一些东西吗？

题:

如何考虑屏幕的矩形形状以确保圆圈精确地绘制到填充边界？

以下适用于"圆形"区域,但不适用于矩形区域......

dx = abs(center.x - place.x);
dy = abs(center.y - place.y);
dh = Math.sqrt((dx * dx) + (dy * dy));
radius = dh - padding;

光环设计:

如果问题似乎不明显,下面的图像代表我正在使用的当前方法.取决于地点的位置影响它伸入屏幕空间的距离.

我收到以下错误:

One or more validation errors were detected during model generation:   
\tSystem.Data.Entity.Edm.EdmEntityType: : EntityType 'UserAccount' has no key defined. Define the key for this EntityType.
\tSystem.Data.Entity.Edm.EdmEntitySet: EntityType: EntitySet 'UserAccounts' is based on type 'UserAccount' that has no keys defined.

此错误由代码触发:

_Db.Database.Initialize(true);

我假设由于某种原因它没有在模型上获取[Key]属性.最初当我尝试运行代码时,我没有添加key属性,这是否意味着已经创建/缓存了某些东西,这阻止了这个密钥的应用？

除了包含Entity Framework 5之外,MVC4项目几乎是一个空白的设置

型号代码

public class AccountContext: DbContext
{
    public AccountContext()
        : base("DefaultConnection")
    {          
    }

    public DbSet<UserAccount> UserAccounts { get; set; }
}

[Table("UserAccount")]
public class UserAccount
{
    [Key]
    [Required]        
    public string Username;

    [Required]
    [DataType(DataType.Password)]
    [StringLength(100, ErrorMessage …

登录

[HttpPost]
public ActionResult Login(LoginModel loginModel)
{
    if (ModelState.IsValid)
    {
        using (var _Db = new AccountContext())
        {
            var _UserAccount = _Db.UserAccounts.FirstOrDefault(u => u.Username == loginModel.Username && u.Password == loginModel.Password);

            if (_UserAccount == null)
            {
                ModelState.AddModelError("", "Account doesn't exist!");
            }
            else
            {
                FormsAuthentication.SetAuthCookie(loginModel.Username, false);
            }
        }
    }
    return RedirectToAction("Index", "Home");
}

重定向或显示视图

public ActionResult Index()
{
    if (HttpContext.User.Identity.IsAuthenticated)
    {
        return View("Index");
    }
    else
    {
        return RedirectToAction("LoginPage");
    }
}

我已经完成了代码,可以看到使用正确的用户名调用SetAuthCookie. FormsAuthentication.SetAuthCookie(loginModel.Username, false);

什么可以阻止用户进行身份验证？

使用Visual Studio 2013构建GenerateFakes成功时,它使用相同目标文件的相同路径.
