• 方法[^本地需安装libreoffice]

  /**
  *@tips libreoffice 转换指令：
  * libreoffice6.2 invisible --convert-to pdf csDoc.doc --outdir /home/[转出目录]
  *
  * @function 实现文档类型转换为pdf或html
  * @param command:libreofficed的命令(具体以版本为准)；win：soffice； linux：libreoffice6.2
  *     fileSrcPath:转换文件的路径
  *         fileOutDir:转换后文件存储目录
  *       converterType：转换的类型pdf/html
  * @return fileOutPath 转换成功生成的文件的路径 error 转换错误
