cannot import name 'token_required'是怎么回事

这个错误通常出现在 Flask 应用程序中,因为 `token_required` 函数是从 Flask-JWT 库中导入的。该函数确保请求中包含有效的 JSON Web Token(JWT)。如果你的应用程序中没有使用 Flask-JWT 库,则会出现此错误。
要解决此问题,你可以在应用程序中导入所需的库,或者确保已正确安装库。如果你已经安装了 Flask-JWT 库但仍然遇到此问题,请确保在应用程序中正确导入 `token_required` 函数。

cannot import name 'token_required'
This error typically occurs when you are trying to use a function or decorator called `token_required` but it cannot be found in the current scope or module.
If you are trying to use the `token_required` decorator from the Flask-RESTful library, you may need to make sure that you have imported it correctly. Here is an example of how to properly import and use `token_required` in a Flask-RESTful application:
```
from flask import Flask
from flask_restful import Api, Resource, reqparse
from flask_jwt_extended import jwt_required, get_jwt_identity
from your_module import token_required
app = Flask(__name__)
api = Api(app)
class SecretResource(Resource):
@jwt_required
@token_required
def get(self):
current_user = get_jwt_identity()
return {'secret': 'Hello, {}! This is a secret message.'.format(current_user)}
api.add_resource(SecretResource, '/secret')
if __name__ == '__main__':
app.run(debug=True)
```
In this example, we have imported `token_required` from `your_module` and used it as a decorator alongside `jwt_required` to protect a resource endpoint. Make sure that the `token_required` function is defined and imported correctly in your module.
cannot import name 'BOS_TOKEN' from 'utils'
这个问题可能是因为你使用的代码没有正确导入 utils 模块中的 BOS_TOKEN。BOS_TOKEN 是一个特殊的标记,用于在文本序列开头表示开始符。请检查你的代码是否正确导入 utils 模块,并且确保 BOS_TOKEN 已经正确定义并可以被调用。如果还遇到问题,请提供更多代码和环境细节,我可以帮助你更好地解决。
