使用Openoffice或LibreOffice实现World、Excel、PPTX在线预览

0180

预览方案

使用第三方服务

有三方服务提供了在线预览文档的功能，可以将文件上传到这些服务，然后嵌入其提供的预览组件到你的网页中。常用的服务包括 Google Docs、Microsoft Office Online 和 Adobe Document Cloud。

1.调用微软的在线预览功能实现

<iframe src='https://view.officeapps.live.com/op/view.aspx?src='+fileurl width='100%' height='100%' frameborder='1'></iframe>
<iframe src='https://view.officeapps.live.com/op/view.aspx?src='+fileurl width='100%' height='100%' frameborder='1'></iframe>
<iframe src='https://view.officeapps.live.com/op/view.aspx?src='+fileurl width='100%' height='100%' frameborder='1'></iframe>

2.调用google的文档在线预览实现

<iframe :src="https://docs.google.com/viewer?url="+fileurl></iframe>
<iframe :src="https://docs.google.com/viewer?url="+fileurl></iframe>
<iframe :src="https://docs.google.com/viewer?url="+fileurl></iframe>

3.调用XDOC文档预览服务

XDOC文档预览服务：https://view.xdocin.com/

XDOC还可以实现文本、带参数文本、html文本、json文本、公文等在线预览，具体实现方法请看官方文档

注意：预览资源必须是公共可访问的

使用前端库

使用一些前端库来实现文档的在线预览。例如，对于Word文档和Excel文件，可以使用mammoth.js或xlsx.js库来解析和渲染文件内容。对于 PDF 文件，可以使用pdf.js库来渲染和显示PDF内容。

excel：https://github.com/qax-os/excelize、https://github.com/tealeg/xlsx

pdf：https://github.com/mozilla/pdf.js

转换格式

将文档转换为特定格式，然后在网页中显示。例如：将Word、Excel、PDF转换成PDF、HTML、图片进行预览。

可以使用jodconverter，它是一个强大的文档转换工具，适用于需要将Office文档转换为其他格式的应用程序。

jodconverter

jodconverter概述

jodconverter是一个开源项目，用于将 Office 文档（如 Word、Excel、PowerPoint 等）转换为其他格式，例如 PDF、HTML、图像等。它基于 Java 平台，并使用 LibreOffice/OpenOffice 作为转换引擎。

jodconverter 提供了简单易用的 API，使开发人员能够在自己的应用程序中集成文档转换功能。它可以与 Java 应用程序一起使用，也可以通过 REST API 进行远程调用。

Github：https://github.com/jodconverter/jodconverter

主要特性

文档转换：jodconverter 可以将各种 Office 文档格式（如 DOCX、XLSX、PPTX 等）转换为其他格式，如 PDF、HTML、图像（PNG、JPEG 等）等。
批量转换：你可以使用 jodconverter 批量转换多个文档，提高转换效率。
异步转换：jodconverter 支持异步转换，可以在后台进行文档转换，不会阻塞主线程。
自定义配置：你可以根据需要配置转换过程中的参数，如输出格式、图像质量、页面大小等。
监听器支持：jodconverter 提供了监听器接口，可以在转换过程中监听转换状态和进度。
多平台支持：jodconverter 可以在多个平台上运行，包括 Windows、Linux 和 macOS。

安装OpenOffice

jodconverter依赖于Apache OpenOffice或LibreOffice,在使用jodconverter之前需要先安装二者其一

Apache OpenOffice是一款免费的开源办公软件套件，包含了文本编辑器、电子表格、演示文稿、图形处理和数据库管理等多种功能。它由Apache软件基金会开发和维护，支持跨平台，可以在Windows、Mac和Linux等操作系统上运行。Apache OpenOffice与Microsoft Office相似，可用于创建、编辑和共享各种文档、报告和电子邮件等内容。

安装LibreOffice

jodconverter依赖于Apache OpenOffice或LibreOffice,在使用jodconverter之前需要先安装二者其一

LibreOffice是一款免费的开源办公套件，它包括文本编辑器、电子表格、演示文稿、绘图和数据库管理工具等多个组件，可以用于处理各种常见的办公任务。LibreOffice由The Document Foundation开发，是OpenOffice.org的一个分支，其源代码是完全开放的，并且提供了对多种操作系统的支持，包括Windows、Mac OS X和Linux等。

配置JodConverter和LibreOffice

通过在应用程序的配置文件中添加以下属性来配置JodConverter和LibreOffice：

jodconverter:
  local:
    enabled: true
    # libreOffice根目录
    office-home: D:\LibreOffice
    # OpenOffice安装地址
    # office-home: D:\OpenOffice 4
    # 同时执行任务的个数,最大进程数
    max-tasks-per-process: 2
    # 开启多个进程，每个端口对应一个进程;设置端口号（任意设置）
    port-numbers: 3000
    # 任务执行的超时时间
    taskExecutionTimeout: 120000
    # 任务队列的超时时间
    taskQueueTimeout: 30000
    # 一个进程的超时时间
    process-timeout: 120000
jodconverter:

  local:

    enabled: true
    # libreOffice根目录
    office-home: D:\LibreOffice
    # OpenOffice安装地址
    # office-home: D:\OpenOffice 4
    # 同时执行任务的个数,最大进程数
    max-tasks-per-process: 2
    # 开启多个进程，每个端口对应一个进程;设置端口号（任意设置）
    port-numbers: 3000
    # 任务执行的超时时间
    taskExecutionTimeout: 120000
    # 任务队列的超时时间
    taskQueueTimeout: 30000
    # 一个进程的超时时间
    process-timeout: 120000
jodconverter:

  local:

    enabled: true
    # libreOffice根目录
