온라인 URL 디코더

My program is writing URL-encoded strings into a text file like this one.

topic1=1&topic2=2&topic3=3&

However, I'm trying to reverse the process by opening the same file and breaking that file up in a manner that I can retrieve into name/value-like pairs.

' Final Challenge Category    Dim sr As StreamReader = New StreamReader("./Game" + nudGameNo.Value.ToString() + "/Final/category.txt")    strLine = WebUtility.UrlDecode(sr.ReadLine)

The closest function that I can find to help is HttpUtility.ParseQueryString but I can't seem to run it in a WinForms application. (Even if I use Imports System.Web)

I've also tried to do a .Split with & being the separator, however problems start up if a particular value contains an & of it's own.

Is it possible to break this form of string up?

import reimport urllibimport HTMLParserurlRegex = re.compile(r'(.+)&data=')match=urlRegex.search('https://na01.safelinks.protection.outlook.com/?url=https%3A%2F%2Foffice.memoriesflower.com%2FPermission%2F%2525%2524%255E%2526%2526*%2523%2523%255E%2524%2525%255E%2526%255E*%2526%2523%255E%2525%2525%2526%2540%255E*%2523%2526%255E%2525%2523%2526%2540%2525*%255E%2540%255E%2523%2525%255E%2540%2526%2525*%255E%2540%2Foffice.php&data=01%7C01%7Cdavid.levin%40mheducation.com%7C0ac9a3770fe64fbb21fb08d50764c401%7Cf919b1efc0c347358fca0928ec39d8d5%7C0&sdata=PEoDOerQnha%2FACafNx8JAep8O9MdllcKCsHET2Ye%2B4%3D&reserved=0')x = match.group()urlRegex_1 = re.compile(r'url=(.+)&data=')match_1 = urlRegex_1.search(x)print match1.group(1)htmlencodedurl = urllib.unquote(urllib.unquote(match1.group(1)))actual_url = HTMLParser.HTMLParser().unescape(htmlencodedurl)

So the 'actual_url' displays this:'https://office.memoriesflower.com/Permission/%$^&&##^$%^&^&#^%%&@^*#&^%'

I need it to display this:

https://office.memoriesflower.com/Permission/office.php

$url is my encoded URL which I am using for redirection. But when this URL gets loaded in browser, hackers can inject malicious code by adding javascript in one of the parameters. What I did here is am again decoding and encoding this URL so that if some one has injected any code it will get automatically un-executable by decode-encode process. Mentioned above is working as expected. Problem comes at the redirection step, when encoded URL hits the browser; browser is automatically converting %3E to > and %3C to <

$url = "https%3A%2F%2Fwww.MYWEBSITENAME.in%2F%27;%3Cinput%20autofocus%20onfocus=alert(document.domain)%3E";$url = urldecode($url);$urld = htmlentities(urlencode($url));header("location:".'http://MYREDIRECTLOCATION&id=111&pname=myproductname&url='.$urld);

// output of htmlentities(urlencode )) is https%3A%2F%2Fwww.MYWEBSITENAME.in%2F%27%3B%3Cinput+autofocus+onfocus%3Dalert%28document.domain%29%3E

My question is how can I stop browser from converting %3E to > and %3C to <, I tried htmlentities but didn't work!

There is a question here on stack overflow that answers PART of my question (see link)https://stackoverflow.com/a/17431971/2461910

Unfortunately, this solution is cumbersome, because it always encodes/decodes the ENTIRE current document.

My question is: How can I change the JavaScript in that solution to only modify whatever text is SELECTED in the current document?

I tried using Editor.currentView.selected, but that throws an error when the script runs. If only I could find a document describing what all functions objects and properties are visible to the jN plugin. I suppose that's a topic for another question. Oh well.

I have the following URL:

https://www.example.com/%2522%25D0%25B7%25D0%25B5%25D0%25BB%25D0%25B5%25D0%25BD-%25D1%2581%25D0%25B2%25D1%258F%25D1%2582%2522

If I unquote the URL, I get the following:

>>> urllib.parse.unquote(url)'https://www.example.com/%22%D0%B7%D0%B5%D0%BB%D0%B5%D0%BD-%D1%81%D0%B2%D1%8F%D1%82%22'

Which tells me that I need to unquote it yet again, like so:

>>> urllib.parse.unquote(url)'https://www.example.com/%22%D0%B7%D0%B5%D0%BB%D0%B5%D0%BD-%D1%81%D0%B2%D1%8F%D1%82%22'

I notice that with most of the URLs that have been encoded twice, they have the %25 (the quote character) in them. Is this efficient for detecting a URL that needs to be decoded twice, or are there more characters? If doing this for billions of URLs, most of which are fine with a single decoding, are there any disadvantages to decoding twice for every URL?
