问题说明 #

处理字符串时，前两次类方法调用正常，但调用self.Reflector(xchar)时触发上述错误。已尝试确保返回值为字符串，仍无法解决。

解决方案 #

核心问题是实例属性与方法重名：
你的类中，存储反射器字符映射的实例属性（比如self.Reflector）和类方法Reflector同名了，导致self.Reflector指向的是字符串类型的属性，而非方法，调用时自然触发“字符串不可调用”的错误。

修正步骤：

1. 修改存储反射器映射的实例属性名称，比如改为self.reflector_map（避免与方法名冲突）；
2. 更新Reflector方法内的访问代码：

def Reflector(self, char):
    # 使用改名后的实例属性访问映射
    xchar = self.reflector_map[(ord(char) - 65) % 26]
    logging.info(f'Input: {char} Returned: {xchar}')
    return str(xchar)

同时检查类的初始化代码，确保反射器映射的变量名是修改后的self.reflector_map，避免再次出现命名冲突。
