온라인 URL 디코더

The following code:

context.Response.Write(    context.Request.Url.AbsolutePath    + "\n" + Uri.UnescapeDataString(context.Request.Url.AbsolutePath)    + "\n" + context.Server.UrlDecode(context.Request.Url.AbsolutePath)    + "\n" + HttpUtility.UrlDecode(context.Request.Url.AbsolutePath));

Outputs:

Using a tool like this one and inputting /uploads/324/d7925fa2-2d3a-4cae-ba3d-e22f48cbe55c/c/1415663111_250/regenera%20hp%20-%20c%C3%B3pia%20(2).png and pressing decode results in:

Why are my attempts at URL decoding not resulting in the correct value?

I'm not sure what this is called so I'm having trouble searching for it. How can I decode a string with unicode from http\u00253A\u00252F\u00252Fexample.com to http://example.com with JavaScript? I tried unescape, decodeURI, and decodeURIComponent so I guess the only thing left is string replace.

EDIT: The string is not typed, but rather a substring from another piece of code. So to solve the problem you have to start with something like this:

var s = 'http\\u00253A\\u00252F\\u00252Fexample.com';

I hope that shows why unescape() doesn't work.

I am using WebClient to fetch som web requests:

public static string PostHttp(string url, Dictionary<string, string> headers, Dictionary<string, string> postParams){    using (WebClient client = new WebClient())    {                        if (headers != null)        {            foreach (var header in headers)            {                client.Headers.Add(header.Key, header.Value);            }        }        var reqparm = new System.Collections.Specialized.NameValueCollection();        if (postParams != null)        {            foreach (var param in postParams)            {                reqparm.Add(param.Key, param.Value);            }        }        byte[] responsebytes = client.UploadValues(url, "POST", reqparm);        return  Encoding.UTF8.GetString(responsebytes);    }}

And I get something like following in Visual Studio:

\\\"see_more_cards_id\\\",\\\"href\\\":\\\"\\\\\\/page_content_list_view\\\\\\/more\\\\\\/?page_id=200168320060101&start_cursor=\\\\u00257B\\\\u002522timeline_cursor\\\\u002522\\\

In post man it looks better here I would just be able to do an url decode:

\"see_more_cards_id\",\"href\":\"\\\/page_content_list_view\\\/more\\\/?page_id=200168320060101&start_cursor=\%7B\%22timeline_cursor\%22\%3

In Chrome debugger its like following:

\"see_more_cards_id\",\"href\":\"\\\/page_content_list_view\\\/more\\\/?page_id=200168320060101&start_cursor=\\u00257B\\u002522timeline_cursor\\u002522\\u00253A\\u002522timeline_unit\\

What I am looking for is a decoded versions like:

"see_more_cards_id","href":\"/page_content_list_view/more/?page_id=200168320060101&start_cursor={"timeline_cursor":""timeline_unit:timeline_unit: 1:00000000001564446283:04611686018427387904:091:00000000001564446283:04611686018`427387904:09

I tried searching for decoding characters like u002522 but there is only a very limited information. I found following post that suggested using Uri.UnescapeDataString but this didnt decode the chars.

Decode chars

How can I decode an encoded URL parameter using C#?

For example, take this URL:

my.aspx?val=%2Fxyz2F

i want to encode a json because it contains special characters

I try to use simple urlencode but it doesn't work. When I print the variable in alert on the js is empty

$sql="select name,surname from agents";$res = $conn->query($sql);while($row = $res->fetch_assoc()) {   $rows[] = $row;}$json = json_encode($rows);echo urlencode($json);
