      • readRawLine

        public static byte[] readRawLine​(java.io.InputStream inputStream)
                          throws java.io.IOException
        Return byte array from an (unchunked) input stream. Stop reading when "\n" terminator encountered If the stream ends before the line terminator is found, the last part of the string will still be returned. If no input data available, null is returned.
        Parameters:
        inputStream - the stream to read from
        Returns:
        a byte array from the stream
        Throws:
        java.io.IOException - if an I/O problem occurs

      • readLine

        public static java.lang.String readLine​(java.io.InputStream inputStream,
                                        java.lang.String charset)
                                 throws java.io.IOException
        Read up to "\n" from an (unchunked) input stream. If the stream ends before the line terminator is found, the last part of the string will still be returned. If no input data available, null is returned.
        Parameters:
        inputStream - the stream to read from
        charset - charset of HTTP protocol elements
        Returns:
        a line from the stream
        Throws:
        java.io.IOException - if an I/O problem occurs

        Deprecated.
        use #readLine(InputStream, String)
        Read up to "\n" from an (unchunked) input stream. If the stream ends before the line terminator is found, the last part of the string will still be returned. If no input data available, null is returned
        Parameters:
        inputStream - the stream to read from
        Returns:
        a line from the stream
        Throws:
        java.io.IOException - if an I/O problem occurs

      • parseHeaders

        public static Header[] parseHeaders​(java.io.InputStream is,

        is - the stream to read headers from
        charset - the charset to use for reading the data
        Returns:
        an array of headers in the order in which they were parsed
        Throws:
        java.io.IOException - if an IO error occurs while reading from the stream
