Spire.Cloud.Storage Java SDK给开发人员提供了FileApi接口，支持操作Word, Excel, PowerPoint, PDF等文件，主要包括文件的上传、移动、复制、下载及删除。本文将介绍如何调用FileApi接口上传文件。

首先：通过Maven仓库安装Spire.Cloud.SDK jar包及依赖，详细步骤可参考这篇文章。

其次：通过冰蓝云官网（https://cloud.e-iceblue.cn/）注册账号并登陆，在“我的应用”创建应用程序，获得App ID及App Key。

import spire.cloud.storage.sdk.Configuration;
import spire.cloud.storage.sdk.api.FileApi;
import java.io.File;

public class CloudWord {

    static String appId = "Your App ID";
    static String appKey = "Your App Key";
    static String baseUrl = "https://api.e-iceblue.cn";
    //配置App ID和App Key
    static Configuration configuration = new Configuration(appId, appKey, baseUrl);
    //创建FileApi实例
    static FileApi fileApi = new FileApi(configuration);

    public static void main(String[] args) throws Exception {
        //设置上传文件的路径及名称，无如文件夹，直接设置文件名称及格式
        String path = "NewWord.docx";

        //本地文件路径及名称
        String localFilePath = "D:/Sample.docx";
        File data = new File(localFilePath);
        String storageName = null;
        //上传文件
        fileApi.uploadFile(path, data, storageName);
    }

    public static void copyFile() throws Exception{
        //复制文件
        String srcPath = "input/test.docx";
        String destPath = "input/test/test2.docx";
        String srcStorageName = null;
        String destStorageName = null;
        fileApi.copyFile(srcPath, destPath, srcStorageName, destStorageName);
    }
        public static void deleteFile() throws Exception{
        //删除文件
        String path = "input/test.docx"; ;
        String storageName = null;
        fileApi.deleteFile(path, storageName);
    }
    public static void downloadFile() throws Exception{
        //下载文件
        String path = "input/test.docx";
        String storageName = null;
        File response = fileApi.downloadFile(path, storageName);
    }
    public static void moveFile() throws Exception{
        //移动文件
        String srcPath = "input/test.pptx";
        String destPath = "output/test/test.pptx";
        String srcStorageName = null;
        String destStorageName = null;
        fileApi.moveFile(srcPath, destPath, srcStorageName, destStorageName);
    }
}
