我有一个带有@jwt_required 装饰器的功能。

class Test(Resource):
    @jwt_required
    def get(self):
        return {"test": "ok" }

当设置正确的 HTTP 标头时，它工作正常，即

Authentication: Bearer [TOKEN]

但是当令牌无效/错误或混乱时，会引发 jwt.exceptions.DecodeError ：

File "env/lib/python3.6/site-packages/flask_restplus/resource.py", line 44, in dispatch_request
    resp = meth(*args, **kwargs)
  File "env/lib/python3.6/site-packages/flask_jwt_extended/view_decorators.py", line 103, in wrapper
    verify_jwt_in_request()
  File "env/lib/python3.6/site-packages/flask_jwt_extended/view_decorators.py", line 32, in verify_jwt_in_request
    jwt_data = _decode_jwt_from_request(request_type='access')
  File "env/lib/python3.6/site-packages/flask_jwt_extended/view_decorators.py", line 267, in _decode_jwt_from_request
    decoded_token = decode_token(encoded_token, csrf_token)
  File "env/lib/python3.6/site-packages/flask_jwt_extended/utils.py", line 80, in decode_token
    encoded_token, verify=False, algorithms=config.algorithm
  File "env/lib/python3.6/site-packages/jwt/api_jwt.py", line 84, in decode
    payload, _, _, _ = self._load(jwt)
  File "env/lib/python3.6/site-packages/jwt/api_jws.py", line 183, in _load
    raise DecodeError('Not enough segments')
jwt.exceptions.DecodeError: Not enough segments

我不能一直依赖客户总是使用正确的令牌。而且我无法捕捉到异常，因为它是在装饰器中引发的，而不是我自己的函数。所以结果是 http 500 错误。我应该如何更优雅地处理异常？

Flask-jwt-extended 应该优雅地为您处理这些问题。如果没有，您可能正在使用另一个破坏本机烧瓶功能的扩展（例如 flask-restful）。您可以尝试设置此选项来修复它app.config[‘PROPAGATE_EXCEPTIONS’] = True，或者如果您使用导致问题的不同烧瓶扩展，请查看此线程以获取一些建议https://github.com/vimalloc/flask-jwt-extended/issues/ 86
