Java 添加、下载、读取PDF附件信息(基于Spire.Cloud.SDK for Java)

 

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:


    
        com.e-iceblue
        cloud
        http://repo.e-iceblue.cn/repository/maven-public/
    



        
             cloud 
            spire.cloud.sdk
            3.5.0
        

        
         com.google.code.gson
        gson
        2.8.1
        

        
             com.squareup.okhttp
            logging-interceptor
            2.7.5
        

        
             com.squareup.okhttp 
            okhttp
            2.7.5
        

        
             com.squareup.okio 
            okio
            1.6.0
        

        
             io.gsonfire
            gson-fire
            1.8.0
        

        
            io.swagger
            swagger-annotations
            1.5.18
        

        
             org.threeten 
            threetenbp
            1.3.5
        

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)
