有谁使用过阿里云oss的吗?多文件多图时怎么上传
前段时间正好做个项目，就是用的oss，普通上传和断点续传，代码贴出来，看是不是你需要的public class OssManage {public static String ACCESS_KEY_ID = null;public static String ACCESS_KEY_SECRET = null;public static String ENDPOINT = null;public static String BUCKETNAME = null;public static String BUCKETNAME_VIDEO = null;public static String OUT_OF_DATE = null;private OSSClient client = null;private ObjectMetadata meta = null;static{try {ACCESS_KEY_ID = SysConst.getProperty("OSS_ACCESS_KEY_ID");ACCESS_KEY_SECRET = SysConst.getProperty("OSS_ACCESS_KEY_SECRET");ENDPOINT = SysConst.getProperty("OSS_ENDPOINT"); BUCKETNAME = SysConst.getProperty("OSS_BUCKETNAME"); BUCKETNAME_VIDEO = SysConst.getProperty("OSS_BUCKETNAME_VIDEO"); OUT_OF_DATE = SysConst.getProperty("OSS_OUT_OF_DATE");} catch (java.lang.Exception e) {e.printStackTrace();}}public void init(){ // 初始化一个OSSClient client = new OSSClient(ENDPOINT,ACCESS_KEY_ID, ACCESS_KEY_SECRET); meta = new ObjectMetadata();}/** * @Description: 上传文件到OSS文件服务器 * @param content 文件流 * @param key 上传为OSS文件服务器的唯一标识 * @param mimeType 文档类型 * @throws Exception * @ReturnType:String OSSObject的ETag值。*/public String uploadFile(InputStream content,String key,String mimeType) throws Exception{//进行初始化init(); // 必须设置ContentLength meta.setContentType(mimeType); // 上传Object.

怎么上传图片到阿里云?
可以通过FTP的形式进行传输。或者是你做好的一个网站，把图片进行上传到网站，这样也到了阿里云的服务器下了。
android 阿里云 对象存储objectkey 是啥玩意
your-object-key就是你希望上传的文件在OSS中的名称，可以用“/"分割。比如：
bucket：mybucket，key=image/2014/1.jpg
上传成功后，对应的OSS域名就是
阿里云oss上传文件怎么返回上传文件的url
阿里云OSS中url中可以实现授权文件上传吗
Oss中url中授权文件上传可以实现
java版代码示例如下：GeneratePresignedUrlRequest generatePresignedUrlRequest =
1）url中包含签名的好像能够实现文件的下载，阿里云能实现url中授权文件上传吗？
new GeneratePresignedUrlRequest(bucketName, key);
2）java版代码示例如下：
generatePresignedUrlRequest.setMethod(HttpMethod.PUT);
generatePresignedUrlRequest.setExpiration(expires);
generatePresignedUrlRequest.addUserMetadata("usermeta", "uservalue"); // If you need to set user metadata
URL url = client.generatePresignedUrl(generatePresignedUrlRequest);
