Spire.Cloud.SDK for Java提供了PdfAttachmentsApi接口添加附件addAttachment()、下载附件downloadAttachment()、获取附件信息getAttachmentsInfo(),本文将通过Java代码示例介绍具体实现方法。详细内容参考以下步骤:

一、导入jar文件。(有2种方式)

(推荐)方式1. 创建Maven项目程序,通过maven仓库下载导入。以IDEA为例,新建Maven项目,在pom.xml文件中配置maven仓库路径,并指定spire.cloud.sdk的依赖,如下:

<repositories>
<repository>
<id>com.e-iceblue</id>
<name>cloud</name>
<url>http://repo.e-iceblue.cn/repository/maven-public/</url>
</repository>
</repositories>
<dependencies>
<dependency>
<groupId> cloud </groupId>
<artifactId>spire.cloud.sdk</artifactId>
<version>3.5.0</version>
</dependency>
<dependency>
<groupId> com.google.code.gson</groupId>
<artifactId>gson</artifactId>
<version>2.8.1</version>
</dependency>
<dependency>
<groupId> com.squareup.okhttp</groupId>
<artifactId>logging-interceptor</artifactId>
<version>2.7.5</version>
</dependency>
<dependency>
<groupId> com.squareup.okhttp </groupId>
<artifactId>okhttp</artifactId>
<version>2.7.5</version>
</dependency>
<dependency>
<groupId> com.squareup.okio </groupId>
<artifactId>okio</artifactId>
<version>1.6.0</version>
</dependency>
<dependency>
<groupId> io.gsonfire</groupId>
<artifactId>gson-fire</artifactId>
<version>1.8.0</version>
</dependency>
<dependency>
<groupId>io.swagger</groupId>
<artifactId>swagger-annotations</artifactId>
<version>1.5.18</version>
</dependency>
<dependency>
<groupId> org.threeten </groupId>
<artifactId>threetenbp</artifactId>
<version>1.3.5</version>
</dependency>
</dependencies>

完成配置后,点击“Import Changes” 即可导入所有需要的jar文件。如果使用的是Eclipse,可参考这里的导入方法。

导入结果:

 

 

方式2手动下载jar包,然后解压文件,手动导入jar,同时还需另行手动导入其他几个jar文件。

 

二、登录冰蓝云账号,创建文件夹,上传文档。

三、创建应用程序,获取App ID及App Key

四、Java代码示例

【示例1】添加附件

import spire.cloud.pdf.sdk.ApiException;
import spire.cloud.pdf.sdk.Configuration;
import spire.cloud.pdf.sdk.api.PdfAttachmentsApi;
import java.io.File;
public class AddAttachment {
static String appId = "App ID";
static String appKey = "App Key";
static String baseUrl= "https://api.e-iceblue.cn";
static Configuration configuration = new Configuration(appId, appKey, baseUrl);
static PdfAttachmentsApi pdfAttachmentsApi = new PdfAttachmentsApi(configuration);
public static void main(String[] args) throws ApiException {
String name = "sample.pdf";//用于测试的PDF源文档
String outPath = "output/AddAttachment.pdf";//结果文档路径(结果文档保存在云端output文件夹下)
File file = new File("test.docx");//加载附件文档
String attachmentFileName = "AddAttachment.docx";//设置附件文档名称
String attachmentDescription = "A Nice File";//附件描述
String folder = "input";//源文档所在文件夹
String storage = null;//冰蓝云提供的2G免费云存储空间
String password = null;//源文档密码
//调用方法添加附件
 pdfAttachmentsApi.addAttachment(name, outPath, file, attachmentFileName, attachmentDescription, folder, storage, password);
}
}

附件添加结果:

 

【示例2】下载附件文档(以上文中生成的PDF文档为例,读取添加的Word附件)

import spire.cloud.pdf.sdk.ApiException;
import spire.cloud.pdf.sdk.Configuration;
import spire.cloud.pdf.sdk.api.PdfAttachmentsApi;
import java.io.File;
public class DownloadAttachment {
//配置账号信息
static String appId = "App ID";
static String appKey = "App Key";
static String baseUrl= "https://api.e-iceblue.cn";
static Configuration configuration = new Configuration(appId, appKey, baseUrl);
static PdfAttachmentsApi pdfAttachmentsApi = new PdfAttachmentsApi(configuration);
public static void main(String[] args) throws ApiException {
String name = "AddAttachment.pdf";//包含附件的PDF源文档
Integer orderNumber = 1;
String folder = "output";//源文档所在云端文件夹
String storage = null;//冰蓝云提供的2G免费云存储空间
String password = null;//源文档密码
//调用方法下载PDF文档中的附件文档
File response = pdfAttachmentsApi.downloadAttachment(name, orderNumber, folder, storage, password);
System.out.println(response);
}
}

读取结果如下,可在路径中查看下载的附件文档:

 

【示例3】获取附件信息

import spire.cloud.pdf.sdk.ApiException;
import spire.cloud.pdf.sdk.Configuration;
import spire.cloud.pdf.sdk.api.PdfAttachmentsApi;
import spire.cloud.pdf.sdk.model.Attachments;
public class GetAttachmentInfo {
//配置账号信息
static String appId = "App ID";
static String appKey = "App Key";
static String baseUrl= "https://api.e-iceblue.cn";
static Configuration configuration = new Configuration(appId, appKey, baseUrl);
static PdfAttachmentsApi pdfAttachmentsApi = new PdfAttachmentsApi(configuration);
public static void main(String[] args) throws ApiException {
String name = "AddAttachment.pdf";//包含附件的PDF源文档
String folder = "output";//源文档所在文件夹
String storage = null;//冰蓝云提供的2G云存储空间
String password = null;//源文档密码
//调用方法获取附件信息
Attachments response = pdfAttachmentsApi.getAttachmentsInfo(name, folder, storage, password);
System.out.println(response);
}
}

附件信息读取结果:

 

 

(完)
