Java 添加、下载、读取PDF中的附件信息
1、（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"E-iceblue官网-在线编辑-帮助文档-WebAPI-Java-通过 Maven 仓库安装 Spire.Cloud Web API "的导入方法。
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（相对比较麻烦一点）。
最终导入结果如下：
1、如下图：
1、如下图：
1、【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：
2、【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：
3、【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);
}
}
信息读取结果：
