urldecode

原理 大多数web程序都会对输入字符进行转换，例如addslashes(),mysql_real_escape_string(), mysql_escape_string()，也就是对单引号',双引号",NULL,反斜杠\进行转义，但是如果程序中存在 urldecode()或者rawurldecode()的话就会出现问题。 当用户传入值时，程序会自动对字符进行一次urldecode,如果程序又进行一次urldecode()，就会出现二次注入，例如?id=1%2527，第一次自动解码为?id=1%27,再进行一次urldecode()变成?id=1' 成功绕过 漏洞挖掘关键字 rawurldecode() urldecode() 来源： https://www.cnblogs.com/cimuhuashuimu/p/11544508.html

I am decoding characters in a URL by using HTTPUtility.URLDecode. Here are the characters I have to decode: %26 = "&" %28 = "(" %29 = ")" %20 = " " %5B = "[" %5D = "]" %2C = "," %23 = "#" %F3 = "ó" (spanish character) HTTPUtility.URLDecode works great on all but the last one. I am doing a find/replace on that last character right now, but hoping there is a better automatic way so I don't have to update the find/replace in the future. You should use an overload of HttpUtility.UrlDecode() that accepts an encoding : HttpUtility.UrlDecode("%F3", Encoding.GetEncoding("ISO-8859-1")) This assumes it

I type the following url into my web browser and press enter. http://localhost/website.aspx?paymentID=6++7d6CZRKY%3D&language=English Now in my code when I do HttpContext.Current.Request.QueryString["paymentID"], I get 6 7d6CZRKY= but when I do HttpContext.Current.Request.QueryString.ToString() I see the following: paymentID=6++7d6CZRKY%3D&language=English The thing I want to extract the actual payment id that the user typed in the web browser URL. I am not worried as to whether the url is encoded or not. Because I know there is a weird thing going on here %3D and + sign at the same time ! But

I just need to decode a URL, for example, replace %2E with . I can hack out a method if one isn't build in, but my assumption is that there must be a URL decoding tool already existing. Mitch Wheat No. But here's one: URL Encoder and Decoder for VB Or something along the lines of (possibly not complete): Public Function URLDecode(ByVal strEncodedURL As String) As String Dim str As String str = strEncodedURL If Len(str) > 0 Then str = Replace(str, "&amp", " & ") str = Replace(str, "&#03", Chr(39)) str = Replace(str, "&quo", Chr(34)) str = Replace(str, "+", " ") str = Replace(str, "%2A", "*")

Is there a way to perform a MySQL query and have one of the columns in the output directly urldecode, rather than have PHP do it. For example this table 'contacts' would contain, ------------------------------------ |name |email | ------------------------------------ |John Smith|johnsmith%40hotmail.com| ------------------------------------ SELECT * FROM `contacts` Would output, John Smith | johnsmith%40@hotmail.com Is there something along the lines of, SELECT name, urldecode(email) FROM `contacts` To output, John Smith | johnsmith@hotmail.com If anyone is still looking for a mysql decode

I have a file with a list of user-agents which are encoded. E.g.: Mozilla%2F5.0%20%28Macintosh%3B%20U%3B%20Intel%20Mac%20OS%20X%2010.6%3B%20en I want a shell script which can read this file and write to a new file with decoded strings. Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.6; en I have been trying to use this example to get it going but it is not working so far. $ echo -e "$(echo "%31+%32%0A%33+%34" | sed 'y/+/ /; s/%/\\x/g')" My script looks like: #!/bin/bash for f in *.log; do echo -e "$(cat $f | sed 'y/+/ /; s/%/\x/g')" > y.log done Here is a simple one-line solution. $ urldecode() {

I wrote a custom xml parser and its locking up on special characters. So naturally I urlencoded them into my database. I can't seem to find an equivalent to php's urldecode() . Are there any extentions for jquery or javascript that can accomplish this? You could use the decodeURIComponent function to convert the %xx into characters. However, to convert + into spaces you need to replace them in an extra step. function urldecode(url) { return decodeURIComponent(url.replace(/\+/g, ' ')); } Shahzeb chohan Check out this one function urldecode (str) { return decodeURIComponent((str + '').replace(/\
