ASP.NET 成员资格使用与任何其他站点完全相同的机制,并且绝对容易受到 Firesheep 攻击。 Cookie 本身无法以防止其被劫持的方式进行加密。与服务器的所有通信都必须使用 SSL 或 WEP 无线加密进行加密,以防止会话劫持。

ASP.NET membership uses the exact same mechanism as any other site and is absolutely vulnerable to Firesheep attack. The cookie itself cannot be encrypted in a way that keeps it from being hijacked. All communication with the server must be encrypted to protect from session hijacking, using SSL or WEP wireless encryption.

ASP.NET 会员资格是否受到 Firesheep 的保护?

更新:

属性 fork=true 无效。

术语fork通常意味着您在任务(而不是您建议的目标)中运行的代码将在不同的进程(Java 术语中的虚拟机)中执行。

由任务的实现者(例如 NAnt 中的 NUnit 或 ANT 中的 Java 任务)来定义 fork 属性的含义。

Updated:

The property fork=true has no effect.

The term fork usually means that the code you run in a task, not target as you suggest, will execute in a different process (Virtual Machine in Java-lingo).

It is up to the implementer of a task, for instance NUnit in NAnt or the Java task in ANT, to define meaning of the fork property.

fork="true" 是什么意思?在 nant 脚本目标中做什么?

将额外的代码放入模块中并使用 -M。这将在循环之前运行。

您甚至可以通过 $ENV{PERL5OPT} 潜入一些东西,尽管开关非常有限;例如,没有 -e-E

我想如果你真的愿意的话,你也可以用 $ENV{PERL_ENCODING} 做一些离谱的事情。

这就是Acme:: 的全部领域。 不要这样做。 ☹

编辑:唯一喜欢的解决方案是非常没有创意且完全简单的INIT{}

Put your extra code in a module and use ‑M. That’ll run before the loop.

You might even be able to sneak something in via $ENV{PERL5OPT}, although the switches are pretty limited; no ‑e or ‑E, for example.

I suppose you could do something outrageous with $ENV{PERL_ENCODING} too, if you really wanted to.

This is all Acme:: territory. Please don’t. ☹

EDIT: The only solution I much like is the very uncreative and completely straightforward INIT{}.

如何指定“循环之前”使用“perl -ne”时的代码?

ExtensibleActionInvoker 声称能够在操作过滤器上执行属性注入。

正确 - 但不要将操作过滤器与可能无法实现它们的属性混淆。在 ASP.NET MVC 中解决此问题的最简洁方法是划分职责,即使 MVC 框架允许您将它们组合起来。

例如,使用一对类 - 一个仅保存数据的属性类:

// Just a regular old attribute with data values
class SomeAttribute : Attribute { ... }

以及一个注入了依赖项的过滤器:

// Gets dependencies injected
class SomeFilter : IActionFilter { ... }

SomeFilter 仅使用从获取 SomeAttribute 属性的典型方法通过 GetCustomAttributes() 的控制器或操作方法来完成所需的任何工作。

然后,您可以使用 ExtensibleActionInvoker 连接过滤器:

builder.RegisterControllers(...).InjectActionInvoker();
builder.RegisterType<ExtensibleActionInvoker>().As<IActionInvoker>();
builder.RegisterType<SomeFilter>().As<IActionFilter>();

它可能比使用属性作为过滤器方法编写的代码多一点,但代码的质量会更好长期来看(例如,通过避免服务定位器解决方案的属性限制和尴尬。)

The ExtensibleActionInvoker claims to be able to perform property injection on action filters.

Correct - but don't confuse action filters with the attributes that might not implement them. The cleanest way to approach this in ASP.NET MVC is to split responsibilities, even though the MVC framework allows you to combine them.

E.g., use a pair of classes - an attribute class that holds data only:

// Just a regular old attribute with data values
class SomeAttribute : Attribute { ... }

And a filter that has dependencies injected:

// Gets dependencies injected
class SomeFilter : IActionFilter { ... }

SomeFilter just uses the typical approach of getting the SomeAttribute attribute from the controller or action method via GetCustomAttributes() to do whatever work is needed.

You can then use ExtensibleActionInvoker to wire up the filter:

builder.RegisterControllers(...).InjectActionInvoker();
builder.RegisterType<ExtensibleActionInvoker>().As<IActionInvoker>();
builder.RegisterType<SomeFilter>().As<IActionFilter>();

It might be a little more code than you'd write using the attribute-as-filter approach, but the quality of the code will be better in the long run (e.g. by avoiding the limitations of attributes and the awkwardness of the Service Locator solutions.)

您需要定义 ELSE:

SELECT LastName, CASE FirstName WHEN 'Ian' THEN JobNo ELSE FirstName END
FROM Employees

我默认返回 FirstName,如果您不希望将其替换为其他内容。只需确保数据类型相同以避免潜在问题(我假设 JobNo 是 varchar 引用代码,用于演示语法)。

You need to define the ELSE:

SELECT LastName, CASE FirstName WHEN 'Ian' THEN JobNo ELSE FirstName END
FROM Employees

I've defaulted to return the FirstName, if you don't want that just replace with something else. Just make sure the datatypes are equivalent to avoid potential issues (I've assumed JobNo is a varchar ref code for purpose of demonstrating syntax).

SQL中使用CASE选择字段?

当我从 initWithCoder 加载子视图控制器时也遇到了这个问题,这是一个初始化的好地方,但请记住,您必须在视图加载后将其添加为实际的子视图。

因此,将这样的内容移出:

[self addChildViewController: self.pageViewController];
[self.view addSubview: self.pageViewController.view];
[self.pageViewController didMoveToParentViewController:self];

...从 init 方法中移出并移至 viewDidLoad 中。并不是说这特别是您的问题,但这可能对其他人有帮助。

I also had this problem when I loaded a child view controller from initWithCoder, which is a good place to initialise, but keep in mind you have to add it as an actual child AFTER the view has loaded.

So shift something like this:

[self addChildViewController: self.pageViewController];
[self.view addSubview: self.pageViewController.view];
[self.pageViewController didMoveToParentViewController:self];

...out of your init method and into viewDidLoad. Not saying this is your problem in particular but this may be helpful to others.

UV 和法线通常由艺术家控制。可以使用 UV 的梯度来计算切线和副法线。一直计算切线和副法线往往有点昂贵,因此您通常会根据基础几何体预先计算它们一次。最好在发货前进行,以减少装载时间。

UVs and normals are usually under the control of the artist. Tangents and binormals can be calculated using the gradient of the UVs. It tends to be a bit expensive to calculate the tangent and binormals all the time, so you usually precalculate them based on the underlying geometry once. Preferably before you ship to reduce loading times.

好的,我找到了解决方案。这并不容易,但最终找到了如何根据字符限制来限制帖子数量。毫无疑问,其他人会发现这个答案很有帮助,代码如下:

<?php

/* Fetches all post data from the Wordpress DB */
$fetched_posts = array(

    'community'     => get_posts('numberposts=3&tag=community'),
    'communication' => get_posts('numberposts=3&tag=communication'),
    'energy'        => get_posts('numberposts=3&tag=energy'),
    'health'        => get_posts('numberposts=3&tag=health'),
    'prosperity'    => get_posts('numberposts=3&tag=prosperity'),
    'simplicity'    => get_posts('numberposts=3&tag=simplicity'),
    'materials'     => get_posts('numberposts=3&tag=materials'),
    'mobility'      => get_posts('numberposts=3&tag=mobility'),
    'aesthetic'     => get_posts('numberposts=3&tag=aesthetic')
);

// Convert all array entries into variables
extract($fetched_posts);

 /**
 * Show menu items will output items from a particular tagged category
 * but only as many that will fit in the navigation menu space.
 * 
 * @param mixed $object
 * @param mixed $maximum
 */
 function show_menu_items($object, $maximum = 70) {

     // Number of elements in the array
     $total   = 0;

     // Total number of characters we've counted
     $counted = 0;

     // The counter for number of iterations
     $counter = 0;

     // Store all of the titles for this particular object
     foreach ($object as $object) {
        $post_titles[] = $object->post_title; 
     }

     // Store the total number of elements in the array
     $total = count($post_titles);

     // If we actually have page nav items
     if ($total != 0) { 

         // For every post title found count the characters
        foreach ($post_titles as $post_title) {

            // Count characters and keep counting for every title
            $counted = $counted + strlen($post_title);

             // Increment the counterizzle
            $counter++;

            // If the length is less than or equal to our maximum
            if ($counted != $maximum) {

                // Display the links
                echo '<a href="#'.url_title($post_title, 'dash', TRUE).'">'.$post_title.'</a>';

                if ($counter != $total) {
                    echo ' | ';
                }

            }

        }

    } else {
        echo 'No for this subject...';
    }


 }

?>

Okay, I worked out the solution. It wasn't easy, but eventually worked out how to limit the number of posts based on character constraints. No doubt others will find this answer helpful, here's the code:

<?php

/* Fetches all post data from the Wordpress DB */
$fetched_posts = array(

    'community'     => get_posts('numberposts=3&tag=community'),
    'communication' => get_posts('numberposts=3&tag=communication'),
    'energy'        => get_posts('numberposts=3&tag=energy'),
    'health'        => get_posts('numberposts=3&tag=health'),
    'prosperity'    => get_posts('numberposts=3&tag=prosperity'),
    'simplicity'    => get_posts('numberposts=3&tag=simplicity'),
    'materials'     => get_posts('numberposts=3&tag=materials'),
    'mobility'      => get_posts('numberposts=3&tag=mobility'),
    'aesthetic'     => get_posts('numberposts=3&tag=aesthetic')
);

// Convert all array entries into variables
extract($fetched_posts);

 /**
 * Show menu items will output items from a particular tagged category
 * but only as many that will fit in the navigation menu space.
 * 
 * @param mixed $object
 * @param mixed $maximum
 */
 function show_menu_items($object, $maximum = 70) {

     // Number of elements in the array
     $total   = 0;

     // Total number of characters we've counted
     $counted = 0;

     // The counter for number of iterations
     $counter = 0;

     // Store all of the titles for this particular object
     foreach ($object as $object) {
        $post_titles[] = $object->post_title; 
     }

     // Store the total number of elements in the array
     $total = count($post_titles);

     // If we actually have page nav items
     if ($total != 0) { 

         // For every post title found count the characters
        foreach ($post_titles as $post_title) {

            // Count characters and keep counting for every title
            $counted = $counted + strlen($post_title);

             // Increment the counterizzle
            $counter++;

            // If the length is less than or equal to our maximum
            if ($counted != $maximum) {

                // Display the links
                echo '<a href="#'.url_title($post_title, 'dash', TRUE).'">'.$post_title.'</a>';

                if ($counter != $total) {
                    echo ' | ';
                }

            }

        }

    } else {
        echo 'No for this subject...';
    }


 }

您真的希望分类跨度具有 display: block 吗?这迫使每个人都走上一条单独的线。从功能上讲,

有点相同(和

有点相同)。

您可能正在寻找 display: inline-block。这使您能够像您一样阻止属性(高度、宽度),但仍使其在周围内容中移动。另一种选择是使用 display: table-cell此处有一个显示支持图表。

Do you really want the classed spans to have display: block? That forces each one onto a seperate line. Functionally, <span style="display: block"> is kinda the same thing as <div> (and <div style="display: inline"> is kinda the same thing as <span>).

You're probably looking for display: inline-block. That gives you the ability to block attributes (height, width) like you are, but still leave it moving around within the surrounding contents. Another alternative is to use display: table-cell. There's a chart of display support here.

或许。也许不是。

您可以编写高效的面向对象代码。您可能会编写低效的结构化代码。

这取决于应用程序、代码编写得如何以及代码的优化程度。一般来说,您应该编写代码,使其具有良好、干净、模块化的架构并且设计良好,然后,如果您遇到性能问题,请优化导致性能问题的热点。

在有意义的地方使用面向对象编程,在有意义的地方使用结构化编程。您不必在其中之一中进行选择:您可以同时使用两者。

Maybe. Maybe not.

You can write efficient object-oriented code. You can write inefficient structured code.

It depends on the application, how well the code is written, and how heavily the code is optimized. In general, you should write code so that it has a good, clean, modular architecture and is well designed, then if you have problems with performance optimize the hot spots that are causing performance issues.

Use object oriented programming where it makes sense to use it and use structured programming where it makes sense to use it. You don't have to choose between one and the other: you can use both.

只要按照这个顺序,

您就可以将任意数量的子元素放在 FrameLayout 中。

<FrameLayout
    >
    <child1
        ....
        android:layout_gravity="center"
        .....
        />
    <Child2
        ....
        android:layout_gravity="center"
        />
</FrameLayout>

所以关键是

在子视图中添加android:layout_gravity="center"

例如:

我将 CustomViewTextView 放在 FrameLayout 上,如下所示

代码:

<FrameLayout
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    >
    <com.airbnb.lottie.LottieAnimationView
        android:layout_width="180dp"
        android:layout_height="180dp"
        android:layout_gravity="center"
        app:lottie_fileName="red_scan.json"
        app:lottie_autoPlay="true"
        app:lottie_loop="true" />
    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:textColor="#ffffff"
        android:textSize="10dp"
        android:textStyle="bold"
        android:padding="10dp"
        android:text="Networks Available: 1\n click to see all"
        android:gravity="center" />
</FrameLayout>

结果:

enter图片描述在这里

Just follow this order

You can center any number of child in a FrameLayout.

<FrameLayout
    >
    <child1
        ....
        android:layout_gravity="center"
        .....
        />
    <Child2
        ....
        android:layout_gravity="center"
        />
</FrameLayout>

So the key is

adding android:layout_gravity="center"in the child views.

For example:

I centered a CustomView and a TextView on a FrameLayout like this

Code:

<FrameLayout
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    >
    <com.airbnb.lottie.LottieAnimationView
        android:layout_width="180dp"
        android:layout_height="180dp"
        android:layout_gravity="center"
        app:lottie_fileName="red_scan.json"
        app:lottie_autoPlay="true"
        app:lottie_loop="true" />
    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:textColor="#ffffff"
        android:textSize="10dp"
        android:textStyle="bold"
        android:padding="10dp"
        android:text="Networks Available: 1\n click to see all"
        android:gravity="center" />
</FrameLayout>

Result:
