Method Detail

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 encodedcharset
- the character set of pairs to be encoded- Returns:
- the urlencoded pairs

- 2.0 final

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 encodedoffset
- the index of the first byte to encodelength
- the number of bytes to encodecharset
- the desired character encoding- Returns:
- The result of the conversion.
- Since:
- 3.0
-
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 encodedcharset
- the desired character encoding- Returns:
- The result of the conversion.
- Since:
- 3.0
-
getBytes
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 encodedcharset
- the desired character encoding- Returns:
- The resulting byte array.
- Since:
- 3.0
-
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.
- Since:
- 3.0
-
getAsciiString
public static java.lang.String getAsciiString(byte[] data, int offset, int length)
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 encodedoffset
- the index of the first byte to encodelength
- the number of bytes to encode- Returns:
- The string representation of the byte array
- Since:
- 3.0
-
getAsciiString
public static java.lang.String getAsciiString(byte[] data)
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- Returns:
- The string representation of the byte array
- Since:
- 3.0
