Dekoder online Url

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);

I'm converting the page to canvas and then canvas to the image. Function convertCanvasToImage returns image link as base64 encoded link. Looking for a solution to decode it cause I'll need that later and would be easier.

Encoded image starts with data:image/png;base64,longString.

I tried

var  decodedData = window.atob(n); and http://www.webtoolkit.info/javascript-base64.html

But it returns chinese characters.

Also, I tried sending the encoded string to the server via ajax and then try with base64_decode. Still, I get odd output.

Any reference or solution how to decode base64 png image and get normal URL of the image? Is it possible for a canvas to return normal URL not encoded?

how to redirect encoded special characters url to proper address?in my project encoded url routing to web page.i created route something like this

{ path: 'welcome/:id', component: WelcomeComponent },

actually i am passing url like http://localhost/welcome%3Fid%3D45but this is not acceptingand it is accepting only http://localhost/welcome?id=45
