類型不正確.os.path.join 期待傳入一個字符串類型的參數(shù), 而你這里傳入了一個_hashlib.HASH類型的對象.
>>> import hashlib>>> hashlib.sha1(b'this is plaintext') <sha1 HASH object @ 0x7f0a100539e0>
我估計(jì)你是想獲取HASH的 16 進(jìn)制結(jié)果.可以用hexdigest方法, 就像這樣:
>>> print(hashlib.sha1(b'this is plaintext').hexdigest())29487b3263304dba8c04fbe1169a8b8044e0bf8e
或者返回 Bytes 類型, 然后再轉(zhuǎn)碼(不推薦):
>>> print(hashlib.sha1(b'this is plaintext').digest())
b')H{2c0M\xba\x8c\x04\xfb\xe1\x16\x9a\x8b\x80D\xe0\xbf\x8e'
