方法详细信息

getString
public static String getString(byte[] data,
                               int offset,
                               int length,
                               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.

参数：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返回：The result of the conversion.

getString
public static String getString(byte[] data,
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.

参数：data - the byte array to be encodedcharset - the desired character encoding返回：The result of the conversion.

getBytes
public static byte[] getBytes(String data,
String charset)
Converts the specified string to a byte array. If the charset is not supported the default system charset is used.

参数：data - the string to be encodedcharset - the desired character encoding返回：The resulting byte array.

getAsciiBytes
public static byte[] getAsciiBytes(String data)
Converts the specified string to byte array of ASCII characters.

参数：data - the string to be encoded返回：The string as a byte array.

getAsciiString
public static 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)

参数：data - the byte array to be encodedoffset - the index of the first byte to encodelength - the number of bytes to encode返回：The string representation of the byte array

getAsciiString
public static String getAsciiString(byte[] data)
Converts the byte array of ASCII characters to a string. This method isto be used when decoding content of HTTP elements (such as responseheaders)
参数：data - the byte array to be encoded返回：The string representation of the byte array
