# 金山中台预览增加SDK以实现打印旋转等功能
# 改造背景
目前金山文档中台在线预览是请求金山文档中台预览接口返回预览地址，直接在页面上进行显示，此方案无法初始化金山文档中台的SDK，使用金山的SDK进行功能扩展。 比如追加实现打印、旋转、禁止pdf图片下载等功能。
本文档提供适配方法：实现初始化金山中台SDK，以方便做功能扩展。
# 适用版本
适用于V9.0及更老版本
V9.0SP1版本已经内置SDK
# 改造方案
预览文件的时候根据金山文档中台预览接口获取到预览地址， 通过WebOfficeSDK.config 方法在指定的挂载节点下创建一个文档应用，url参数为预览接口返回的地址，其他参数可以根据需求自定义，此时就可以调用文档应用对象的打印、旋转等方法。
# 适配版本
本次适配的中台版本为v6、v7，金山v5版本不适用。
# 可参考代码
Ctp-Studio 客开复用插件：金山中台在线预览支持打印旋转下载
# 涉及的工程
apps-api、apps-common、apps-office-plugins-front、apps-office-plugins、ctp-common、ctp-core
# 支持功能
1、公文、协同所有类型的正文在线预览支持打印、下载； 2、正文打印支持节点权限控制； 3、word、excel、ppt、pdf、ofd格式的附件线预览支持打印、下载； 4、pdf格式文件在线预览禁用图片下载； 5、pdf、ofd正文、附件支持左旋转、右旋转。
# 改动点
# apps-api
修改java类com.seeyon.apps.officePlugins.util.OfficeFileUtil.java
在pdfExts数组变量中加入“ofd”，原因是金山文档中台ofd格式文件预览调用的是pdf的接口，如下所示：
# apps-common
新增open-jssdk-v0.0.11.umd.js文件
此文件为金山文档中台官方提供的在线预览的sdk文件
# apps-office-plugins-front
修改BuildConfig.js文件
将金山在线预览需要编译的文件加入到entrys变量中，如下图所示：
新增webOfficePreview.html文件
webOfficePreview.html文件为挂载在线预览的页面，用于将在线预览的地址挂载到此页面元素中，页面渲染的时候需要加载open-jssdk-v0.0.11.umd.js和webOfficePreview.js文件，代码如下：

# apps-office-plugins
1、com.seeyon.apps.officePlugins.enums.WebOfficeEnums.java
在TypeEnum枚举中增加OnlinePreviewForV6枚举，如图所示：
2、com.seeyon.apps.officePlugins.helper.WebOfficeURLHelper.java
1)、增加setHeadersForWps4方法
public HttpHeaders setHeadersForWps4(URI url,HttpHeaders headers){
String path=url.getPath()+"?"+url.getQuery();
if (path.startsWith("/open")) {
path = path.replace("/open", "");
}

headers.add("Wps-Docs-Authorization", String.format("WPS-4 %s:%s", SystemGlobalConstant.WEBOFFICE_APPID, signature));
return headers;
}
2)、修改mapToWebOfficeUrlForPri方法
/**

UriComponentsBuilder builder;
if(isV6&&isPreview) {

} else {

}
});

HttpEntity<String> requestEntity;
if(isV6&&isPreview) {
headers=setHeadersForWps4(urlResult,headers);

}
LOGGER.info(MessageFormat.format("请求中台-2-：{0}，耗时{1}ms", this.webOfficeUrl+ typeEnum.getUrl(),System.currentTimeMillis()-t1));
return res.getUrl();
}
3、com.seeyon.apps.wpsassist.manager.WpsAssistOfficeApiImpl.java
添加如下代码：
4、新增java类com.seeyon.apps.weboffice.util.HMacUtil.java
package com.seeyon.apps.weboffice.util;
import javax.crypto.Mac;
import javax.crypto.spec.SecretKeySpec;
import java.security.MessageDigest;
import java.security.NoSuchAlgorithmException;
/**
* @author ranjf

if (temp.length()==1){
//1得到一位的进行补0操作
stringBuffer.append("0");
}
stringBuffer.append(temp);
}
return stringBuffer.toString();
}
}
5、新增Java类：com.seeyon.apps.officePlugins.vo.middleground.GetOnlinePreviewResponse.java
package com.seeyon.apps.officePlugins.vo.middleground;
import com.fasterxml.jackson.annotation.JsonInclude;
import com.fasterxml.jackson.annotation.JsonProperty;

public void setData(Map<String, Object> data) {
this.data = data;
}
public String getCode() {
return code;
}
public void setCode(String code) {
this.code = code;
}
public String getMsg() {
return msg;
}
public void setMsg(String msg) {
this.msg = msg;
}
}
6、修改java类：com.seeyon.apps.weboffice.manager.WpsWebOfficePreviewAdapter.java
1)、修改filter方法
修改前：
修改后：
最终代码如下：
public boolean filter(HttpServletRequest request, HttpServletResponse response) throws Exception {
// url中 包含文件名和其父级路径，如：-23634523412345123/-23634523412345123.html；-23634523412345123/file001.jpg
String viewURL;
String webOfficePreviewUrl= SystemEnvironment.getContextPath() +"/common/office/html/webOfficePreview.html";
try {
// 检查浏览器对于webOffice的兼容性
checkBrowserCompatible(request);
Object[] o = extractFileId(request.getRequestURI());
String suffix = request.getParameter("fileSuffix");
if(StringUtils.isNoneEmpty(suffix)){
suffix=suffix.replace(".","");
}
long fileId = (Long) o[0];
String fileName = request.getParameter("fileName");
if(Strings.isBlank(fileName)){
fileName=request.getParameter("dcs_titleName");
}
if(suffix==null){
if(fileName!=null&&fileName.lastIndexOf(".")>-1){
suffix=fileName.substring(fileName.lastIndexOf(".")+1);
}
}
viewURL = buildWpsPreviewUrl(request, String.valueOf(fileId),suffix);
viewURL += "&_w_third_watermark=" + URLEncoder.encode(StringUtils.trimToEmpty(getWatermarkText(request)), "utf-8").replaceAll("\\+","%20");
if (StringUtils.isNoneEmpty(fileName)){
viewURL += "&_w_third_filename=" + URLEncoder.encode(fileName,"UTF-8");
}
if (StringUtils.isNoneEmpty(suffix)){
viewURL += "&_w_third_suffix=" +suffix;
}
String fileCreateDate = request.getParameter("fileCreateDate");
if (StringUtils.isNoneEmpty(fileCreateDate)){
viewURL += "&_w_third_fileCreateDate=" + fileCreateDate;
}
//如果文件类型为空，并且不在支持的类型范围 走老的预览逻辑
if(suffix!=null&& OfficeFileUtil.getFileTypeCode(suffix)!=null) {
String userAgentForm=AppContext.getCurrentUser().getUserAgentFrom();
String ctxPath=SystemEnvironment.getContextPath();
webOfficePreviewUrl += "?ctxPath="+ctxPath+"&userAgentForm="+userAgentForm+"&fileId="+fileId+"&fileSuffix="+suffix+"&fileName="+URLEncoder.encode(fileName,StandardCharsets.UTF_8.toString())+"&viewUrl=" + URLEncoder.encode(viewURL, StandardCharsets.UTF_8.toString());
}else {
webOfficePreviewUrl=viewURL;
}
}catch (BrowserCompatibleException exception){
LOG.error("BrowserCompatibleException",exception);
return writeErrorMessageToBrower(response,9);
}catch (Exception exception){
LOG.error("",exception);
return writeErrorMessageToBrower(response,8);
}
redirect(response,webOfficePreviewUrl);
return false;
}
2)、修改buildWpsPreviewUrl方法，添加如红框中的代码
7、修改Java类com.seeyon.apps.wpsassist.manager.WpsAssistOfficeApiImpl.java
SUPPORT_SUFFIX集合中添加MIMETypeSuffix.ofdMIMEType.getSuffix()
8、修改java类：com.seeyon.ctp.rest.resources.WebOfficeV6CallbackResource.java
1)、添加静态常量：REP_TOKEN
private static final String REP_TOKEN = "x-wps-weboffice-token";
2)、修改getFileInfo方法，修改点如图：
修改前：
修改后：
# ctp-common
1、com.seeyon.ctp.common.content.mainbody.handler.impl.AbstractOfficeMainbodyHandler.java
修改getContentHtml()方法，如下图：
2、com.seeyon.ctp.common.content.mainbody.handler.impl.OFDMainbodyHandler.java
修改getTransView()方法，如下图：
3、com.seeyon.ctp.common.taglibs.support.EditorSupport.java
修改showOfficeHtmlContent()方法，如下图所示：
**4、com.seeyon.ctp.common.taglibs.support.ShowContentSuppert.java **
修改showOfficeHtmlContent()方法，如下图所示：
com.seeyon.ctp.common.web.filter.WebOfficeAuthenticator.java
修改authenticate()方法，获取token的时候先从header获取，如果没有就从url中获取，获取token的代码改为如下所示：
String tolen = Strings.isBlank(request.getHeader(REP_TOKEN)) ? (Strings.isBlank(request.getParameter("_w_tolen"))?request.getParameter("_w_third_tolen"):request.getParameter("_w_tolen")) : request.getHeader(REP_TOKEN);
# ctp-core
修改java类：com.seeyon.ctp.common.office.trans.util.OfficeTransHelper.java
