刚刚发现这个有效:

#include <sys/types.h>
#include <sys/socket.h>
#include <sys/ioctl.h>
#include <net/if.h>
#include <stdio.h>
#include <string.h>

void mac_eth0(unsigned char MAC_str[13])
{
    #define HWADDR_len 6
    int s,i;
    struct ifreq ifr;
    s = socket(AF_INET, SOCK_DGRAM, 0);
    strcpy(ifr.ifr_name, "eth0");
    ioctl(s, SIOCGIFHWADDR, &ifr);
    for (i=0; i<HWADDR_len; i++)
        sprintf(&MAC_str[i*2],"%02X",((unsigned char*)ifr.ifr_hwaddr.sa_data)[i]);
    MAC_str[12]='\0';
    close(s);
}

int main(int argc, char *argv[])
{
    unsigned char mac[13];

    mac_eth0(mac);
    puts(mac);

    return 0;
}

Just found this to be working:

#include <sys/types.h>
#include <sys/socket.h>
#include <sys/ioctl.h>
#include <net/if.h>
#include <stdio.h>
#include <string.h>

void mac_eth0(unsigned char MAC_str[13])
{
    #define HWADDR_len 6
    int s,i;
    struct ifreq ifr;
    s = socket(AF_INET, SOCK_DGRAM, 0);
    strcpy(ifr.ifr_name, "eth0");
    ioctl(s, SIOCGIFHWADDR, &ifr);
    for (i=0; i<HWADDR_len; i++)
        sprintf(&MAC_str[i*2],"%02X",((unsigned char*)ifr.ifr_hwaddr.sa_data)[i]);
    MAC_str[12]='\0';
    close(s);
}

int main(int argc, char *argv[])
{
    unsigned char mac[13];

    mac_eth0(mac);
    puts(mac);

    return 0;
}

一种方法是使用存储库模式。为此,您在 Model 文件夹中创建 Repository 对象,并将所有与数据库相关的方法放入其中。您的控制器调用存储库类来获取数据。这允许您将真实的模型对象与数据库访问方法分开。

One approach is to use the repository pattern. To do this, you create Repository objects in your Model folder and you place all of you database-related methods in them. Your controllers call the repository classes to get the data. This allows you to separate the real model objects from the database accessing methods.

模型视图控制器:控制器或模型是否从服务器获取数据?

我知道这已经有很多年了,OP现在很可能已经找到了解决方案,但对于任何遇到这个问题的人来说,这是我的简单解决方案。

  var navBarHeight = $('#navBar').height();
            $('html, body').animate({
                scrollTop: $("#scrollDestination").offset().top-navbarheight
            }, 1000);

I know this is years old and the OP has most likely found a solution by now, but here's my simple solution for anyone who comes across this anyway..

  var navBarHeight = $('#navBar').height();
            $('html, body').animate({
                scrollTop: $("#scrollDestination").offset().top-navbarheight
            }, 1000);

使用百分比 % 滚动到顶部 .offset()

不应该拥有任何没有src属性的标签!

但是您可以使用$(' img:not([src]), img[src=""]') 选择 src 属性为空或缺失的图像。

You are not supposed to have any <img/> tags without a src attribute!

But you can use $('img:not([src]), img[src=""]') to select images with empty or missing src attrs.

当您说您的 Python 进程“生成并执行”cgi-php 脚本时,我相信您的意思是“它通过执行 PHP CLI 可执行文件来调用我的 PHP 脚本,并将我的脚本的名称传递给它。”

使用 PHP CLI 可执行文件,不会自动设置 HTTP 特定的超全局变量和环境值。您必须在 Python 服务器进程中读取所有 HTTP 请求标头和 GET/POST 数据,然后在 PHP 脚本使用的环境中设置它们。

整个实验听起来很有趣,但这就是 mod_php 已经做的事情。

When you say your Python process "spawns and executes" a cgi-php script, I believe what you mean is "it calls my PHP script by executing the PHP CLI executable, passing it the name of my script."

Using the PHP CLI executable, HTTP-specific superglobals and environment values will not be set automatically. You would have to read in all HTTP request headers and GET/POST data in your Python server process, and then set them in the environment used by your PHP script.

The whole experiment sounds interesting, but this is what mod_php does already.

从 CGIHTTPServer 访问 POST 请求数据 (python)

问题似乎仅存在于企业库验证中。我使用 NetTiers 验证重新生成了项目,但没有遇到问题。我无法弄清楚问题是什么,但通过 NetTiers 验证生成项目使问题消失了。

The issue seems to be just in the Enterpise Library validation. I regenerated the project with NetTiers validation and I don't have the issue. I wasn't able to figure out what the issue was, but generating the project with the NetTiers validation made the problem go away.

发问者特别要求 CSS 解决方案,但根据答案,需要添加更多行以保留 href='page.html'。对我来说正确的方法应该是添加 onclick HTML 属性。这是解决方案;

<a style="" href="page.html" onclick="this.href=''">page link</a>

这样可以将 href 链接保留在编码中以供将来使用。

Questioner specifically asks for CSS solution but according to answers more lines needs to be added just to keep href='page.html'. To me correct approach should be adding onclick HTML attribute. Here is the solution;

<a style="" href="page.html" onclick="this.href=''">page link</a>

This way href link can be kept in coding for future usage.

是否可以使用 CSS 使 HTML 锚标记不可点击/不可链接?

解决明文密码问题的提示:

  • 访问并登录Artifactory。
  • 登录后,单击屏幕右上角的用户名。
  • 将您的密码输入 em Unlock 按钮,启用加密密码。
  • 复制将在屏幕下方显示的标签并将其粘贴到 settings.xml 文件中。如果您只想复制密码,请确保它与下面显示的标签完全一致,包括密码开头的“\”。
  • 请记住使用 POM.xml 中定义到标签中的服务器 ID 来调整标签
  • 单击“更新”按钮并准备就绪!检查下一个项目发布时是否一切顺利。

Tip to solve the problem with the clear text password:

  • Access and login into Artifactory.
  • Once you are logged in, click over your user name, on the superior right corner of the screen.
  • Put your password then clique in the em Unlockbutton, enabling the encrypted password.
  • Copy the tag that will be showed on the inferior part of the screen and paste it into the settings.xml file. If you prefer to just copy the password, be sure about let it exactly equals the tag showed below, including the "\" at the beginning of the password.
  • Remember to adjust the tag with the id of your server, defined into the tag, in your POM.xml
  • Click in Update button and ready! Check if everything will occur well at the next project's publication.

有优雅的解决方法吗?

从 C++11 开始,您可以使用 using 声明 来继承来自基类的构造函数(不包括默认、复制或移动构造函数):

class Parent
{
public:
  Parent(int i) { }
};

class Child : public Parent
{
public:
  using Parent::Parent; // inherits Parent(int)
};

int main()
{
  Child child(4);
  return 0;
}

Is there an elegant workaround?

Since C++11, you can use a using declaration to inherit constructors (not including default, copy or move constructors) from a base:

class Parent
{
public:
  Parent(int i) { }
};

class Child : public Parent
{
public:
  using Parent::Parent; // inherits Parent(int)
};

int main()
{
  Child child(4);
  return 0;
}

为什么 C++构造函数继承?

我今天遇到了同样的问题。重新启动 XCode 并没有解决我的问题。我可以通过使用项目“派生数据”“删除”选项使事情恢复正常,该选项可以在<强>组织者。组织者表示,“派生数据包括索引、构建输出和日志”。我猜想索引构建输出导致了这个问题。

I encountered the same problem today. Restarting XCode did not fix the problem for me. I was able to get things back to normal by using "Delete" option of "Derived Data" of the project that can be found under Organizer. Organizer says that, "Derived Data includes index, build output and logs". I guess that either index or build output was causing this issue.

我注意到这个问题主要发生在我安装了 nuget 包之后。添加nuget包后我发现我无法签出。重新启动 Visual Studio 会有所帮助。

基于此讨论:

我使用了这个似乎有效的解决方案:
(如果网页消失,我已将解决方案复制到此处)

Control Panel / Internet Options / Security Tab
Select "Local Intranet"
Click Sites button
Click Advanced Button
Add your TFS server http address to the list. e.g. http://tfs
Restart Visual Studio

不要让“Internet 选项”部分欺骗了您。我不使用 Internet Explorer,这解决了我的问题。

I noticed that the problem occurred mostly after i installed a nuget package. After adding a nuget package i found that I could not check out. Restarting Visual Studio helped.

Based on this discussion:

i used this solution which appears to be working:

它正在寻找不存在的文件,
如果解决方案中缺少您的诡计,它将不允许构建。

这是解决方案中的问题,认为文件存在,如果您通过 Windows 资源管理器查看文件应该所在的位置,则它不再存在。所以它试图复制不存在的文件..

希望这有帮助

--误读

文件上的右键。
选择选项构建操作并选择内容
复制到输出目录 选择始终复制(这将确保将文件复制到目录中)

发布,文件应该在那里

,您应该准备好开始:)

It is looking for file that does not exists,
if your wile is missing in solution it will not allow to build.

this is problem in solution thinking that file is exists and if you look via windows explorer to location where the file is supossed to be, it is not there anymore. So it is trying to copy nonexisting file ..

Hope this helps

--misread

right button on the file.
select option build action and select content
copy to output directory select copy always (this will ensure coping the file into the directory)

publish and the file should be there

and you should be ready to go:)

如果您不以 -A 开头,即使 CLI 也可能调用 SHOW TABLES。

Even the CLI may call SHOW TABLES if you don't start it with -A.

mysql 可以自动触发 SHOW TABLES 吗?

Boost Geometry 库 昨天发布,有一个实现<代码>凸包算法。一张图片表达了一千多个单词:

在此处输入图像描述

尽管这构建了一个“新的” ' 非凹形(即凸形)的形状;这可能是也可能不是您想要的。然而,在此过程中,算法必然能够对凹/凸形状进行分类,因此您可能仍然对该库感兴趣。

有关凸包算法的一般信息:


由于 Adrian Japon 或多或少地建议“命中测试”(遏制测试)是关心凸/凹几何形状的常见原因,而无需话不多说,我将重点介绍相应的 Boost Geometry 算法:

再说一遍,真的是因为图片太漂亮了。请注意,虽然图片建议查询多边形上的点,但这些算法是完全通用的,可用于测试另一个n多边形的完全包含子>

在此处输入图像描述

The Boost Geometry library that was published yesterday, has an implementation of Convex Hull algorithm. A picture says more than a thousand words:

enter image description here

Although this constructs a 'new' shape that is non-concave (i.e. convex); This may or may not be precisely what you want. However, in the process the algorithm is bound to be able to classify shape a concave/convex, so you'd likely be interested in the library nonetheless.

General information on convex hull algorithm:


Since Adrian Japon more or less suggested that 'hit testing' (containment test) is of a usual reason to care about convex/concave geometries, without further ado, I'll highlight the corresponding Boost Geometry algorithm for that: within.

Again, really because the picture is so pretty. Note that though the picture suggests querying for a point against a polygon, the algorithms are fully generic and can be used to test complete containment on n-dimensional polygons in another
