nginx_proxy - 请教大神:PHP或Nginx如何在301重定向中伪造referer?
需求是这样的,用户访问a.com时将其重定向到b.com,同时不能让b.com通过referer检测到用户是从a.com过来的。
请问大神这样的功能能否实现?

思路就不对。
不管你是PHP的重定向,Nginx的重定向,甚至前端JS的重定向。
都无所谓。。。。。。最后都是浏览器执行重定向的操作的。
Referer或者Origin之类的参数,是浏览器加上去的。
要看具体浏览器的具体情景,不同的浏览器表现完全不一样(或者说,基本无法预测和控制)。
Update:
有看到一些其他的思路,不过都有局限,也没什么保证,可以参考

试试把a.com做成https
重定向的地址归根还是浏览器去执行了,楼主可以做个中转,a.com
重定向到c.com
,再重定向b.com
referer是浏览器发出的,不是nginx和php所能决定的
后台方案:通过proxy,对b.com做一个透明代理。
前台方案:通过js,或者链接
如果你是在某个网站比如A.com,有个链接点击之后进入b.com,然后要消除refer,把链接改成下面这样子:
<code><a rel="noreferrer" onclick="noreferclick(this);" href="b.com" target="_blank">xxx</a> function noreferclick(o){ var b,e,c,g,d,f,h;b=$(o);c=b.attr("href"); e="<meta http-equiv="Refresh" content='0; URL="+$("<p/>").text(c).html()+"'>"; if($.browser.webkit){ b.attr("rel","noreferrer"); return true; } var userAgent = navigator.userAgent.toLowerCase(); if(userAgent.indexOf("firefox")!=-1){ if(b.attr("added")){ return true; } else{ h="data:text/html;charset=utf-8,"+encodeURIComponent(e); b.attr("added",1); b.attr("href",h); return true; } } else{ var a=b.attr("target")||"_self"; switch(a){ case "_self": case window.name: a=window; break; default: a=window.open(null,a); break; } a=a.document; a.clear(); a.write(e); a.close(); return false; } } </code>
大部分浏览器适用。
如果不是,比如c.com点击链接到a.com,然后转b.com,只有a.com是可控的。参考上面的点击操作做个js跳转。

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

The core benefits of PHP include ease of learning, strong web development support, rich libraries and frameworks, high performance and scalability, cross-platform compatibility, and cost-effectiveness. 1) Easy to learn and use, suitable for beginners; 2) Good integration with web servers and supports multiple databases; 3) Have powerful frameworks such as Laravel; 4) High performance can be achieved through optimization; 5) Support multiple operating systems; 6) Open source to reduce development costs.

What’s still popular is the ease of use, flexibility and a strong ecosystem. 1) Ease of use and simple syntax make it the first choice for beginners. 2) Closely integrated with web development, excellent interaction with HTTP requests and database. 3) The huge ecosystem provides a wealth of tools and libraries. 4) Active community and open source nature adapts them to new needs and technology trends.

PHP is a server-side scripting language used for dynamic web development and server-side applications. 1.PHP is an interpreted language that does not require compilation and is suitable for rapid development. 2. PHP code is embedded in HTML, making it easy to develop web pages. 3. PHP processes server-side logic, generates HTML output, and supports user interaction and data processing. 4. PHP can interact with the database, process form submission, and execute server-side tasks.
