使用java，简单的将关键代码粘出： jsp页面通过html提交file 后台： byte[] data = file.getBytes(); 生成token private String getUpToken(String key) { if (auth == null) { auth = Auth.create(ACCESS_KEY, SECRET_KEY); } return auth.uploadToken(BUCKET, key); } 上传字节数组 public String uploadFile(byte[] data) { UploadManager manager = new UploadManager(); String key = "test.jpg"; try { manager.put(data, key, getUpToken(key)); } catch (QiniuException e) { e.printStackTrace(); return null; } return DOWNLOAD_DOMAIN + key; } 上传本地文件 public String uploadFile(String path) { UploadManager manager = new UploadManager(); String key = "test.jpg"; try { manager.put(path, key, getUpToken(key)); } catch (QiniuException e) { e.printStackTrace(); return null; } return DOWNLOAD_DOMAIN + key; }
