问题
老规矩，先上代码：
from flask import Blueprint, request, session
from src.api.urlSet import MyEnum
from flask_jwt_extended import create_access_token, jwt_required, get_jwt_identity, get_jwt
class sysTest():
def __init__(self):
self.bp = Blueprint("sys", __name__, url_prefix="/sys/")
self.Myenum = MyEnum()
self.bp.route(self.Myenum.route1, methods=['POST'])(self.route1)
self.bp.route(self.Myenum.route2, methods=['GET'])(self.route2)
@jwt_required
def route1():
pass
@jwt_required
def route2():
pass
看着很正常吧，但启动的时候 坑来了～

重点看：
AssertionError: View function mapping is overwriting an existing endpoint function: sys.wrapper
各种AI ，百度，Google 没有找到答案！ 在 www.5axxw.com/questions/c… 找到 类似的bug ，但按照 这位大神 的方法，是无法解决我的问题的 呜呜～～～不过也在其中受到了启发
AI 给的答案 是
from flask import Blueprint bp = Blueprint("sysUser", __name__, url_prefix="/sys/user") def route1(): pass def route2(): pass bp.add_url_rule('/route1', view_func=route1, endpoint='route1') bp.add_url_rule('/route2', view_func=route2, endpoint='route2')
但我的 '/route1' 是从 Myenum 中读取的，所以 在保持 源码 的情况下解决问题的方法是：
from flask import Blueprint, request, session
from src.api.urlSet import MyEnum
from flask_jwt_extended import create_access_token, jwt_required, get_jwt_identity, get_jwt
class sysTest():
def __init__(self):
self.bp = Blueprint("sys", __name__, url_prefix="/sys/")
self.Myenum = MyEnum()
self.bp.add_url_rule(self.Myenum.route1, methods=['POST'],
view_func=self.route1, endpoint='route1')
self.bp.add_url_rule(self.Myenum.route2, methods=['GET'],
view_func=self.route2, endpoint='route2')
@jwt_required
def route1():
pass
@jwt_required
def route2():
pass
呜呜～～～真是太难了～
