      • formUrlEncode

        public static java.lang.String formUrlEncode​(NameValuePair[] pairs,
                                                     java.lang.String charset)
        Form-urlencoding routine. The default encoding for all forms is `application/x-www-form-urlencoded'. A form data set is represented in this media type as follows: The form field names and values are escaped: space characters are replaced by `+', and then reserved characters are escaped as per [URL]; that is, non-alphanumeric characters are replaced by `%HH', a percent sign and two hexadecimal digits representing the ASCII code of the character. Line breaks, as in multi-line text field values, are represented as CR LF pairs, i.e. `%0D%0A'.

        if the given charset is not supported, ISO-8859-1 is used instead.

        Parameters:
        pairs - the values to be encoded
        charset - the character set of pairs to be encoded
        Returns:
        the urlencoded pairs

      • getString

        public static java.lang.String getString​(byte[] data,
                                                 int offset,
                                                 int length,
                                                 java.lang.String charset)
        Converts the byte array of HTTP content characters to a string. If the specified charset is not supported, default system encoding is used.
        Parameters:
        data - the byte array to be encoded
        offset - the index of the first byte to encode
        length - the number of bytes to encode
        charset - the desired character encoding
        Returns:
        The result of the conversion.

      • getString

        public static java.lang.String getString​(byte[] data,
                                                 java.lang.String charset)
        Converts the byte array of HTTP content characters to a string. If the specified charset is not supported, default system encoding is used.
        Parameters:
        data - the byte array to be encoded
        charset - the desired character encoding
        Returns:
        The result of the conversion.

        public static byte[] getBytes​(java.lang.String data,
                                      java.lang.String charset)
        Converts the specified string to a byte array. If the charset is not supported the default system charset is used.
        Parameters:
        data - the string to be encoded
        charset - the desired character encoding
        Returns:
        The resulting byte array.

      • getAsciiBytes

        public static byte[] getAsciiBytes​(java.lang.String data)
        Converts the specified string to byte array of ASCII characters.
        Parameters:
        data - the string to be encoded
        Returns:
        The string as a byte array.

        Converts the byte array of ASCII characters to a string. This method is to be used when decoding content of HTTP elements (such as response headers)
        Parameters:
        data - the byte array to be encoded
        offset - the index of the first byte to encode
        length - the number of bytes to encode
