方法详细资料

encode

public static String encode(String string)

Encode string as a byte array in Base64 annotation.

参数:

string -

返回:

The Base64-encoded data as a string

encodeBytes

public static String encodeBytes(byte[] source)

Encodes a byte array into Base64 notation.

参数:

source - The data to convert

返回:

The Base64-encoded data as a String

抛出:

NullPointerException - if source array is null

IllegalArgumentException - if source array, offset, or length are invalid

从以下版本开始:

2.0

encodeBytes

public static String encodeBytes(byte[] source,
                                 int off,
                                 int len)

Encodes a byte array into Base64 notation.

参数:

source - The data to convert

off - Offset in array where conversion should begin

len - Length of data to convert

返回:

The Base64-encoded data as a String

抛出:

NullPointerException - if source array is null

IllegalArgumentException - if source array, offset, or length are invalid

从以下版本开始:

2.0

encodeBytesToBytes

public static byte[] encodeBytesToBytes(byte[] source,
                                        int off,
                                        int len)

Similar to encodeBytes(byte[], int, int) but returns a byte array instead of instantiating a String. This is more efficient if you're working with I/O streams and have large data sets to encode.

参数:

source - The data to convert

off - Offset in array where conversion should begin

len - Length of data to convert

返回:

The Base64-encoded data as a String if there is an error

抛出:

NullPointerException - if source array is null

IllegalArgumentException - if source array, offset, or length are invalid

从以下版本开始:

2.3.1

decode

public static byte[] decode(String str)
                     throws UnsupportedEncodingException

抛出:

UnsupportedEncodingException

decoder

public static String decoder(String str)
                      throws UnsupportedEncodingException

抛出:

UnsupportedEncodingException
