    try {

        `${this.apiBaseUrl}${this.discussionApiPath}?lemmaId=${lemmaId}`,
        {
          headers: {
            "Content-Type": "application/json",

      return response.data;
    } catch (error: unknown) {
      if (axios.isAxiosError(error) && error.response) {
        throw new Error(`百度百科API错误: ${error.response.status} - ${JSON.stringify(error.response.data)}`);
      }
      throw error;
