        public static java.lang.String readLine​(java.io.InputStream inputStream)
                                 throws java.io.IOException
        Read a line of bytes from an InputStream. Useful when an InputStream may contain both text and binary data.
        Parameters:
        inputStream - A source of data
        Returns:
        A line of text read from inputStream, with terminating \r\n or \n removed, or null if no data is available.

        java.io.IOException - on trouble reading from input stream

      • readRawLine

        public static byte[] readRawLine​(java.io.InputStream inputStream)
                          throws java.io.IOException
        Reads a raw line from an InputStream, up till \n. Since HTTP allows \r\n and \n as terminators, this gets the whole line. This code is adapted from org.apache.commons.httpclient.HttpParser
        Parameters:
        inputStream - A stream to read from.
        Returns:
        Array of bytes read or null if none are available.
        Throws:
        java.io.IOException - if the underlying reads fail
