Why wouldn't dns_get_record show CNAMEs when I KNOW they exist?

I'm playing with DNS record lookup in PHP and am running into something confusing. I've looked up 2 different domains each using different hosts and different authoritative name servers. Both of these domains I know for certain have CNAMES. I've looked up DNS records using this online tool: http://network-tools.com/ I've also looked them up using PHP's dns_get_record. A, NS, SOA, MX, etc. all come back. But no CNAMES. I get false/empty array. In both cases I can log into the DNS control for these domains and see the CNAMES. Why in the world would this be happening? The goal is to allow lookup

1.绘制描边文本 ctx.strokeText(str,x0,y0) 参数一:需要绘制的文本 参数二三:文本绘制的基点(文字默认在基点的右上方) 它有自己的独立路径 ctx.strokeStyle:设置文本颜色 ctx.font:设置文本,语法与 CSS font 属性相同。详见https://www.runoob.com/cssref/pr-font-font.html 注意:即使拥有独立路径,依然会继承前面代码设置的绘制样式,包括描边颜色,虚线 <script> var canvas = document.querySelector("canvas") var ctx = canvas.getContext("2d") //绘制中心线 ctx.moveTo(0,canvas.height/2) ctx.lineTo(canvas.width,canvas.height/2) //绘制虚线 ctx.setLineDash([5,10]) //描边 ctx.stroke() //开启路径 ctx.beginPath() ctx.moveTo(canvas.width/2,0) ctx.lineTo(canvas.width/2,canvas.height) //绘制虚线 ctx.setLineDash([5,10]) //描边 ctx.stroke() //以正中央为基点绘制文本)

Amazon S3: using DNS alias to bucket + HTTPS at the same time

I want to create an S3 bucket in the Frankfurt zone, and make the files accessible with the URL: https://files.stample.co/filename So I want both HTTPS, and a custom DNS alias (CNAME) at the same time. According to what I understand, Amazon has a wildcard certificate for URL https://*.s3.amazonaws.com . HTTPS / SSL So this wildcard will: Work for https://stample-files.s3.amazonaws.com Not work for https://files.stample.co.s3.amazonaws.com So what I understand and confirmed by other StackOverflow posts is that if I want SSL to work I have to use a bucket name with no dot otherwise the Amazon

解压文件,首先熟悉程序的功能与需求: 第一步:打开软件有一个nag窗口,嗯,这个是要去掉的(都让你kill了,这么贱的要求,就满足他吧) 然后是主要界面,注册,退出 两个功能都是一样的,都是注册的意思,这是我们要完成的(main 目标) 没有其他的需求了,点击Exit和x都没有nag窗口。 第二步:查壳与脱壳 没有壳,Delohi编写 第三步:破解 载入OD,通过查找字符串,看到nag窗口的文字 双击字符串,找到位置,发现这是一个函数,应该就是那个窗体函数了, 下断,运行,retn后回到call函数下方,nop掉刚刚的函数,导出。运行一下,nag已经去掉。 验证部分: 第一种:爆破 找到字符串,查看对应位置 可以看到,失败和成功之间有一个jnz判断,只要不实现跳转,那么就是成功 所以,直接nop掉这个jnz的判断语句,那么就成功爆破了。 同样的,后面的校验也是如此: 找到这个位置,nop掉对应的jnz判断 然后保存并导出,3.0版本已经完全爆破成功。 然而,不会写注册机的逆向不是一个好的逆向,所以,得看看注册码的加密方式。 方法二:逆向算法 菜鸡看了大佬的wp, https://www.52pojie.cn/thread-264393-1-1.html 找到判断验证的位置,下断并运行一下,能看到堆栈和系统的备注信息: 可以通过结果和注释,能够猜测,注册码应该是CW-XXXX

How to redirect siteA to siteB with A or CNAME records [closed]

I have 2 hosts and I would like to point a subdomain on host one to a subdomain on host two: subdomain.hostone.com --> subdomain.hosttwo.com I added a CNAME record to host one that points to subdomain.hosttwo.com but all I get is a ' 400 Bad Request ' Error. Can anyone see what I'm doing wrong? Eric Z Beard Try changing it to "subdomain -> subdomain.hosttwo.com" The CNAME is an alias for a certain domain, so when you go to the control panel for hostone.com, you shouldn't have to enter the whole name into the CNAME alias. As far as the error you are getting, can you log onto subdomain.hostwo

Why isn’t it possible to use a CNAME redirect with HTTPS

This Google Storage documentation page states that You can use a CNAME redirect only with HTTP, not with HTTPS. But I cannot see any reason for that. Can anyone explain me why? kupson Assume you have a CNAME record: travel-maps.example.com CNAME c.commondatastorage.googleapis.com. Browser resolves name travel-maps.example.com and gets IP for c.commondatastorage.googleapis.com , then connects to port 443 of this address. Server with this IP couldn't possibly have proper certificate for travel-maps.example.com (and all other domain names with CNAME records like this). Only example.com domain

ASP.NET Mvc Razor视图语法

在ASP.NET MVC中有两套模版引擎,一套是ASPX,一套是Razor,从事过WebForms开发的朋友们,对于ASPX模版已经很熟悉了,下面我说一下我所熟悉的Razor模版引擎的一些语法,供大家参考: 在ASPX中我们使用 <% %> 在里面编写C#代码 在Razor中我们将会使用 @ 符号这个核心语法,给程序员提供了大量的便利,废话不多说,我一一举例: 1.首先如何定义变量,我们在 .cshtml 这个视图上,定义C#变量的话,我们可以先定义一个C#代码块,在这个代码块里编写C#语法 定义一个C#代码块: @{   //定义一个变量   string name="我是一个字符串"; } //输出这个字符串 @name 2.假如我们现在有一个需求,让我们输出10个<span>我爱北京天安门</span>,那么肯定要使用for循环了 @for(var i=0;i<10;i++){ <span>我爱北京天安门</span> } 有同学可以有疑问了,为什么我们在C#代码段里面可以直接写html标签,ASPX里我们必须将C#代码放在<%%>中,因为Razor引擎有一个非常强大的功能,那就是自动识别<>(尖括号),当在Razor中遇到<>的时候,Razor会自动识别这里是Html语法,看到@符号就知道开始编写C#代码了。 那么我们就有疑问了,Razor视图是如何识别的呢? 在ASPX中
