java - Scala Play WS.put Array[Bytes] setting negative bytes to 0b111111 -

-

i doing http put of array[byte] using play's web service client. reason, setting negative bytes 63 (0b111111). sent same byte stream using java's http stuff , sent on byte array properly. hints?

here example:

    //play web service send bytes     val bytes = array[byte](0, -3, 2, ...)     ws.url(httpservice).put(bytes)       //java send bytes     val j = new url(httpservice)     val con = j.openconnection().asinstanceof[httpurlconnection]     con.setdooutput(true)     con.setrequestmethod("put")     val out = con.getoutputstream.asinstanceof[bytearrayoutputstream]     out.write(bytes)     out.close()      val input = con.getinputstream     while (input.available() > 0) input.read()      input.close()     con.disconnect()

i had set character set iso-8859-1. in general better use base64 send byte array on line; however, couldn't in context of problem. below example of solution. note, setting content type application/octet-stream before , didn't work. fix charset=iso-8859-1 addition.

  ws.url(url).withheaders("content-type" -> "application/octet-stream;charset=iso-8859-1")
