PHP的pack("H*", $str)转换为java函数
最近在接一个PHP的接口,使用到pack("H*", $str),怎么进行转换呢,如下:public static byte[] str2pack(String str) {
int nibbleshift = 4;
int position = 0;
int len = str.length()/2 + str.length()%2;
byte[] output = new byte;
for (char v : str.toCharArray()) {
byte n = (byte) v;
if (n >= '0' && n <= '9') {
n -= '0';
} else if (n >= 'A' && n <= 'F') {
n -= ('A' - 10);
} else if (n >= 'a' && n <= 'f') {
n -= ('a' - 10);
} else {
continue;
}
output |= (n << nibbleshift);
if (nibbleshift == 0) {
position++;
}
nibbleshift = (nibbleshift + 4) & 7;
}
return output;
}
