aliyun-sdk-oss-2.5.0.jar 這個文件 如果有最新版的話就下載最新版
aliyun.upload.AliyunConfigpackage aliyun.upload;public final class AliyunConfig { //你的oss所在域,要加http:// 不明白可以對照你的文件引用地址 public static String endpoint = "http://oss-cn-shenzhen.aliyuncs.com"; //密匙keyId 可以在阿里云獲取到 public static String accessKeyId = "xxxxxxx"; //密匙keySecret 可以在阿里云獲取到 public static String accessKeySecret = ""; //你的bucketName 名稱 即是你的OSS對象名稱 不明白查oss開發文檔專業術語 public static String bucketName = "";}
