^符号在网址中的含义是什么？ [英] What does a ^ sign mean in a URL?

问题描述

我需要从网页抓取一些链接数据，并且我正在使用一个简单的手写PHP抓取工具它。爬虫通常工作正常;然后我来到这样的网址：

http://www.example.com/example.asp?x7=3^^^ ^^ select％20col1，col2％20 from％20table％20where％20recordid％3E = 20 ^^^^^

当在浏览器中键入时，但我的搜寻器无法检索此页面。我得到一个HTTP请求失败的错误。

解决方案

插入符号（^）不是URL中的保留字符，应该按原样使用。但是，如果您遇到问题，只需用它的十六进制编码替换％5E 。

是的， URL中的原始SQL就像是一个闪烁的大霓虹灯，读着EXPLOIT ME PLEASE！。无论谁设计的网站是脑死亡。

What is the meaning of a ^ sign in a URL?

I needed to crawl some link data from a webpage and I was using a simple handwritten PHP crawler for it. The crawler usually works fine; then I came to a URL like this:

http://www.example.com/example.asp?x7=3^^^^^select%20col1,col2%20from%20table%20where%20recordid%3E=20^^^^^

This URL works fine when typed in a browser but my crawler is not able to retrieve this page. I am getting an "HTTP request failed error".

解决方案

Caret (^) is not a reserved character in URLs, so it should be acceptable to use as-is. However, if you re having problems, just replace it with its hex encoding %5E.

And yeah, putting raw SQL in the URL is like a big flashing neon sign reading "EXPLOIT ME PLEASE!". Whoever designed the site in question is brain-dead.
