TypeError: a bytes-like object is required, not 'str' - hmac

Question

我看到这个错误：

TypeError: a bytes-like object is required, not 'str' 
    python3.6/base64.py", line 58, in b64encode encoded = binascii.b2a_base64(s, newline=False)`

代码如下：

import base64
import hmac
import hashlib
import binascii

....
def post(self,request):
    body = str(request.body).encode()
    sign_signature = base64.b64encode(hmac.new('tester'.encode(), body, hashlib.sha256).hexdigest())

Answer 1

将您的代码行替换为：

sign_signature = base64.b64encode(hmac.new('tester'.encode(), body, hashlib.sha256).digest())

digest returns bytes -> we want to b64encode it, and b64encode accepts bytes, so we're good.
