有以下几个错误：

1. 在 `get_url` 方法中，需要在 `self` 参数之前添加 `@staticmethod` 装饰器，使其成为静态方法。

2. 在 `get_book_list` 方法中，`print(book_list)` 应该改为 `print(self.book_list)`，因为 `book_list` 是类成员变量。

3. 在 `get_book_list` 方法中，将 `self.bbok_list` 改为 `self.book_list`。

4. 在 `get_chapter_list` 方法中，将 `self.chapter_list.append((a["href"],a.text.replace("\n","")))` 改为 `self.chapter_list.append((self.root_url+a["href"],a.text.replace("\n","")))`，因为需要获取完整的章节链接。

5. 在 `get_content` 方法中，将 `print(url)` 和 `print(book_name)` 改为注释，因为这些是调试信息。

改正后的代码如下：
