У продаји УРЛ Енцодер

In one of my PHP based project, I need to pass some parameter (through HTTP GET method), those values are in Arabic.

So what I did is: I am using PHP function urlencode() before passing them through URL, and those encoded values seems OK. But the problem arises when I want to use those values in the target URL page. I mean suppose the encoded value is: %23%F8%A7%F9%83%F8%AB%F8%B1_%F9%85%F9%85%F8%A7_%F8%AA%F8%AA%F9%88%F9%82%F8%B9

Now in the show page, the output it prints by echo is #������������������������

The above is what I got after decoding!

Which is obviously not properly decoded.

Can anyone know how can I solve this problem?

I am creating a site using CodeIgniter. I have an url like http://mysite.com/albums/MJ/Dangerous.html where MJ is the artist name and Dangerous is the name of the album. Both of these are dynamic and fetched from a database.

In the database there are some albums which have a slash ('/') character in them. So, such an URL becomes http://mysite.com/albums/50-cent/Get+Rich+or+Die+Tryin%27%2FThe+Massacre.html. On decoding, it turns out as http://ringtones/albums/50-cent/Get Rich or Die Tryin'/The Massacre.html. Here the artist is 50-cent and the album name is Get Rich or Die Tryin'/The Massacre

My question is, what do I do so that I get the entire album name, i.e. Get Rich or Die Tryin'/The Massacre.html as a single argument with the slash character? Currently CodeIgniter shows an error as "Page not found" when I click on such an URL. All other URL's which doesn't have the / works fine.

Occasionally getting "Unauthorized Error" when my Base64 encoded token contains a "+" sign (which is a valid Base 64 character)

I am using Visualize-JS to render the Jasper report in MVC Boilerplate. To authenticate every request, I am using the pre authorization flow where I am sending a Base64 encoded token from my application and on Jasper server decoding it.

Everything is working fine except, occasionally I am getting "Unauthorized Error". When I checked I found it is only failing when my Base64 encoded token contains a "+" sign (which is a valid Base 64 character). My C# code is URL encoding the + sign as %2B whereas the Java code while decoding the same URL converts %2B into a space. (Note - I am encoding in C# and decoding in Java since, Jasper server only supports JAR files).

Is anyone else facing this or have faced earlier and found the solution?

For now, as a work around I am replacing the space with a + sign but, I am searching for a better solution.

Here is the faulty token, C# code for encoding and Java code for decoding

C# Code for Encryption -

    public string Encrypt(string plainText)    {        byte[] plainBytes = Encoding.UTF8.GetBytes(plainText);        return HttpUtility.UrlEncode(Convert.ToBase64String(Encrypt(plainBytes, GetRijndaelManaged(_config.EncryptionKey))));    }    public RijndaelManaged GetRijndaelManaged(string secretKey)    {        byte[] keyBytes = new byte[16];        byte[] secretKeyBytes = Encoding.UTF8.GetBytes(secretKey);        Array.Copy(secretKeyBytes, keyBytes, Math.Min(keyBytes.Length, secretKeyBytes.Length));        return new RijndaelManaged        {            Mode = CipherMode.CBC,            Padding = PaddingMode.PKCS7,            KeySize = 128,            BlockSize = 128,            Key = keyBytes,            IV = keyBytes        };    }    public byte[] Encrypt(byte[] plainBytes, RijndaelManaged rijndaelManaged)    {        return rijndaelManaged.CreateEncryptor().TransformFinalBlock(plainBytes, 0, plainBytes.Length);    }

Java Code - encryptedText here is the token mentioned above

    public String decrypt(String encryptedText){        encryptedText = decode(encryptedText);        byte[] cipheredBytes = Base64.getDecoder().decode(encryptedText);        byte[] keyBytes = getKeyBytes(secretKey);        return new String(decrypt(cipheredBytes, keyBytes, keyBytes), "UTF-8");    }    public static String decode(String url)      {          try {              String prevURL="";              String decodeURL=url;              while(!prevURL.equals(decodeURL))              {                  prevURL=decodeURL;                  decodeURL=URLDecoder.decode( decodeURL, "UTF-8" );            }              return decodeURL.replace(" ", "+");        } catch (UnsupportedEncodingException e) {              return "Issue while decoding" +e.getMessage();          }      }    private byte[] getKeyBytes(String key) throws UnsupportedEncodingException{        byte[] keyBytes= new byte[16];        byte[] parameterKeyBytes= key.getBytes("UTF-8");        System.arraycopy(parameterKeyBytes, 0, keyBytes, 0, Math.min(parameterKeyBytes.length, keyBytes.length));        return keyBytes;    }

Is there a way to use the Nodejs URL module to url encode binary data?

For example, the set of bytes \x12\x34\x56\x78\x9a, once encoded is equivalent to %124Vx%9a.

I don't have a problem doing this in Python:

>>> urllib.parse.urlencode({'q':b'\x12\x34\x56\x78\x9a'})'q=%124Vx%9A'

Trying this in Nodejs I get the wrong encoding as %124Vx%EF%BF%BD:

> u = new URL('http://www.google.com');> qvar = Buffer('123456789a','hex')<Buffer 12 34 56 78 9a>> u.searchParams.set('q',qvar.toString('utf8'))> uURL {  href: 'http://www.google.com/?q=%124Vx%EF%BF%BD',  origin: 'http://www.google.com',  protocol: 'http:',  username: '',  password: '',  host: 'www.google.com',  hostname: 'www.google.com',  port: '',  pathname: '/',  search: '?q=%124Vx%EF%BF%BD',  searchParams: URLSearchParams { 'q' => '\u00124Vx�' },  hash: ''}

If I could pass in the byte buffer directly to searchParams.set() I am guessing I'd have more luck. The URL object expects strings for its parameters, so how can I convert raw hex to a string that it will properly quote?

Do you know a fast and simple way to encode a Javascript Object into a string that I can pass via a GET Request?

No jQuery, no other frameworks - just plain Javascript :)
