We know that `WWW` has a contructor with a `byte[ ]` parameter as the post data, and it’s quite handy to deal with encoding senstive servers. Why doesn’t `UnityWebRequest.Post` has a similar overload? I know the string post data version but it’ll cause our Django server to complain.

I think you can do something like this:
```csharp
byte[] ByteArray;
UnityWebRequest WebRequest = new UnityWebRequest( URL , UnityWebRequest.kHttpVerbPOST );
UploadHandlerRaw MyUploadHandler = new UploadHandlerRaw( ByteArray );
MyUploadHandler.contentType= "application/x-www-form-urlencoded"; // might work with 'multipart/form-data'
WebRequest.uploadHandler= MyUploadHandler;
```

Thanks for your answer. Yup, we can use this, but this doesn’t smell good.

System.Text has string encoders built-in:
UnicodeEncoding.Unicode.GetString(bytearray)
Same for ASCII, UTF8, UTF32, etc. …
Set up the handler as a PUT, apply the message body, change the method to a POST and Unity won’t auto-mangle the content.

Thanks. It seems WWWForm instead of WWWForm.data work for us.

Actualy you can!
using (UnityWebRequest www = new UnityWebRequest(markerURL))
{
yield return www;
byte[ ] yourBytes = [www.downloadHandler.data;](http://www.downloadHandler.data;)

You can.
string pathToImage = null;
using (UnityWebRequest www = new UnityWebRequest(markerURL))
{
yield return www;
byte[ ] yourBytes = [www.downloadHandler.data;](http://www.downloadHandler.data;)
pathToImageC = Application.persistentDataPath + “/” + f\_type;
if (!Directory.Exists(Path.GetDirectoryName(pathToImageC)))
Directory.CreateDirectory(Path.GetDirectoryName(pathToImageC));
else
{
Directory.Delete(pathToImageC);
Directory.CreateDirectory(Path.GetDirectoryName(pathToImageC));
}
System.IO.File.WriteAllBytes(pathToImageC, yourBytes);
}
