Question

I am trying to assign the encrypted value into session storage in .cshtml file. but I couldn't. I am getting a different error each time. Error I got: Uncaught SyntaxError: Unexpected token ')' , Uncaught SyntaxError: Invalid left-hand side in assignment

<script type="text/javascript">
@{
    string createApplicationRequestPKey =Request.QueryString["cpk"];
    if(createApplicationRequestPKey != null)
    {
                @:sessionStorage.setItem('CreateApplicationRequestPKey', @createApplicationRequestPKey);
                @:location.href = '/';
            }
        }</script>

Sample request :url?cpk=U2FsdGVkX1+S3rsDcNeHuP5g6LokgGx9/xV1QcSVR+g=

Try using the encodeURI function in javascript :

    string createApplicationRequestPKey = encodeURI(Request.QueryString["cpk"]);

If you are using c# on the server side use base64 or urlencode:

    public static string Base64Encode(string plainText) {
      var plainTextBytes = System.Text.Encoding.UTF8.GetBytes(plainText);
      return System.Convert.ToBase64String(plainTextBytes);
    }
    public static string Base64Decode(string base64EncodedData) {
      var base64EncodedBytes = System.Convert.FromBase64String(base64EncodedData);
      return System.Text.Encoding.UTF8.GetString(base64EncodedBytes);
    }

    string encoded = System.Web.HttpUtility.UrlEncode(cpk);
