使用onlyoffice让你轻松实现word、ppt、excel在线编辑功能
一、了解onlyoffice
ONLYOFFICE Docs是一个开源办公套件，包括文本文档、电子表格和演示文稿的编辑器。它提供以下功能：
1、创建、编辑和查看文本文档、电子表格和演示文稿；
2、与其他队友实时协作处理文件；
3、ONLYOFFICE Docs 还支持用于将您的应用程序与在线办公室集成的WOPI 协议。
二、前提准备
搭建安装onlyoffice，具体参考官网地址：
https://helpcenter.onlyoffice.com/installation/docs-developer-install-ubuntu.aspx?from=api_csharp_example
三、开发进行中
1、准备一个接口返回config配置文件。
@GetMapping("/config/{fileId}")
@ApiOperation("返回配置信息")
public String getConfig(ModelMap map,@PathVariable String fileId){
//具体业务处理省略
//主要是获取一些信息，用于设置html中的脚本对象config上。
//4、设置视图数据：a、文件类型。b、用户信息。c、文件信息。
map.addAttribute("docType",documentType);
map.addAttribute("user",user);
map.addAttribute("fileManager",fileManager); //将html页面返回回去
return "onlineEdit";
}2、准备一个callback接口用于文件保存。
@PostMapping("/saveFile/{fileId}/{fileCode}")
@ApiOperation("在线编辑保存回调接口")
@ResponseBody
public void saveFile(HttpServletRequest request , HttpServletResponse response, @PathVariable String fileId, @PathVariable String fileCode) throws IOException {
PrintWriter writer = response.getWriter();
Scanner scanner = new Scanner(request.getInputStream()).useDelimiter("\\A");
String body = scanner.hasNext() ? scanner.next() : "";
JSONObject jsonObject = JSONObject.parseObject(body);
System.out.println(jsonObject);
//status等于2时表示已经准备好保存
if((Integer) jsonObject.get("status") == 2){
//2、根据返回的Url去下载文件
URL url = new URL((String) jsonObject.get("url"));
java.net.HttpURLConnection connection = (java.net.HttpURLConnection) url.openConnection();
InputStream stream = connection.getInputStream();
//此处获取到的流即是onlyoffice服务下的文件流。
//3、重新上传业务省略
connection.disconnect();
}
writer.write("{\"error\":0}");
}3、准备一个html页面。
