【问题描述】：
首先：非常感谢 Authlib 创建者/其他开源创建者和支持者。
我希望 Authlib 0.11 将 oauth 令牌作为 JWT 返回。 我尝试按照 Authlib 网站中提供的文档创建一个带有 Authlib 0.11 https://docs.authlib.org/en/latest/flask/2/authorization-server.html#token 的 JWT 令牌生成器。
由于我是这个主题的新手，我仍然无法找出将我的 JWT 令牌生成器方法传递给 config:OAUTH2_ACCESS_TOKEN_GENERATOR 的正确方法
感谢任何帮助。
这是我的虚拟 jwt 令牌生成器：
from authlib.jose import jwt
def gen_access_token(client, grant_type, user, scope):
log.debug('Not used yet in the JWT:: {} \n{} \n{} \n{}'.format( client, grant_type, user, scope))
header = {'alg': 'RS256'}
payload = {
'iss': 'http://127.0.0.1:5000/oauth/token',
'sub': 'test client',
'aud': 'profile'
}
try:
key = open('wf-app-server.key', 'r').read()
s = jwt.encode(header, payload, key)
claims = jwt.decode(s, open('wf-app-pub.pem', 'r').read())
except Exception as e:
log.debug('JWT exception', e)
log.debug("jwt encoded:{}\n decoded :{} \n header:{}".format(
s, claims, claims.header))
return s
OAUTH2_REFRESH_TOKEN_GENERATOR = True
OAUTH2_TOKEN_EXPIRES_IN = {
'authorization_code': 874000,
'implicit': 3600,
'password': 600000,
'client_credentials': 600000
}
OAUTH2_ACCESS_TOKEN_GENERATOR = gen_access_token('bCsNV2Lo8hxD593Km84lWM5d', 'client_credentials', 'admin', 'profile')
-- 显示我的 JWT 令牌生成器的输出可以正确解码返回值--

首先，为了测试我的 oauth 令牌请求凭据是否正确，我尝试从 Authlib 请求具有正确 client_credentials 和默认 token_generator 的 oauth 令牌。有了这个，我得到了默认的 oauth 令牌。
其次，我使用令牌生成器更新了配置，然后当我请求具有相同客户端凭据的 oauth 令牌时，我收到以下错误：
2019-06-22 13:40:56,700 DEBUG authenticate_client_secret_basic (65)
Authenticate bCsNV2Lo8hxD593Km84lWM5d via "client_secret_basic"
success
I created this custom debug line below to understand what the default access_token_generator() takes as input parameters. It is exactly take the same types - my input parameter types also match!

当我将我的 gen_acc_token() 方法传递给配置时，我知道我做错了 - 但无法准确找出问题所在。
通过一个示例 gen_JWT_access_token() 的小代码 sn-p 会很棒。
