問(wèn)題描述

當(dāng)我用java上傳文件到七牛服務(wù)器后，如何讓七牛返回訪問(wèn)該文件的url。

public static void uploadFile(String localFilePath,String fileName){Configuration cfg = new Configuration(Zone.zone1());//...其他參數(shù)參考類注釋UploadManager uploadManager = new UploadManager(cfg);//...生成上傳憑證，然后準(zhǔn)備上傳String accessKey = 'your access key';String secretKey = 'your secret key';String bucket = 'your bucket name';//如果是Windows情況下，格式是 D:qiniutest.png//String localFilePath = '/home/qiniu/test.png';//默認(rèn)不指定key的情況下，以文件內(nèi)容的hash值作為文件名String key = null;Auth auth = Auth.create(accessKey, secretKey);String upToken = auth.uploadToken(bucket);try { Response response = uploadManager.put(localFilePath, key, upToken); //解析上傳成功的結(jié)果 DefaultPutRet putRet = new Gson().fromJson(response.bodyString(), DefaultPutRet.class); System.out.println(putRet.key); System.out.println(putRet.hash);} catch (QiniuException ex) { Response r = ex.response; System.err.println(r.toString()); try {System.err.println(r.bodyString()); } catch (QiniuException ex2) {//ignore }} }

問(wèn)題解答

七牛不會(huì)返回文件的url你只需判斷上次成功了 URL 你就知道了bucket 對(duì)應(yīng)的IP 或 域名 http://aa.com

那么你的圖片訪問(wèn)路徑就是：

http://aa.com/自定義的文件名稱
