1576059389832
返回值：[49, 53, 55, 54, 48, 53, 57, 51, 56, 57, 56, 51, 50]
返回值：[49, 53, 55, 54, 48, 53, 57, 51, 56, 57, 56, 51, 50]
返回值：[49, 53, 55, 54, 48, 53, 57, 51, 56, 57, 56, 51, 50]
注意：getBytes() 默认是UTF-8，Str1.getBytes() 返回byte数组地址
用Arrays.toString()进行内容打印
python bytearray
a = '1576059389832'
b = bytearray(a, encoding='utf-8')
print(b)
print([x for x in bytearray('1576059389832','windows-1252')])
print([x for x in bytearray('1576059389832','utf_8')])
print([x for x in bytearray('1576059389832','gbk')])
print([x for x in bytearray('1576059389832','latin_1')])
bytearray(b'1576059389832')
bytearray(b'1576059389832')
[49, 53, 55, 54, 48, 53, 57, 51, 56, 57, 56, 51, 50]
[49, 53, 55, 54, 48, 53, 57, 51, 56, 57, 56, 51, 50]
[49, 53, 55, 54, 48, 53, 57, 51, 56, 57, 56, 51, 50]
[49, 53, 55, 54, 48, 53, 57, 51, 56, 57, 56, 51, 50]
注意：print([x for x in bytearray('1576059389832', 'utf_8')]) 进行byte数组内容的输出，
bytearray('1576059389832',encoding='utf-8') 返回bytearray(b'1576059389832’）
