Question

我正在使用PyCharm CE和Flask在Python中编写RESTful API。我尝试将基本身份验证添加到API。我在应该需要登录的函数之前添加了@ auth.login_required。我添加了一个返回True或False的@ auth.verify_password函数。但是，每次此函数返回True时，它都会显示＆＃34; TypeError：视图函数未返回有效响应。函数返回None或没有return语句结束。＆＃34;在Insomnia中执行此操作时，它表示500内部服务器错误。这是我的代码

auth = HTTPBasicAuth()

@auth.verify_password
def verify(username, password):
    if not username and password:
        return False
    if username == "Num of Users":
        return False
    if username in userData:
        return str(userData[username]) == str(password)
    return False

以及它吐出的其他信息
