- Ver 1.0.0不建议使用
- 开发环境: Java 1.7或以上
- 运行环境: Java 1.7或以上
- 
Maven 您可以通过在pom.xml中添加以下依赖项,来配置您的Maven项目 <dependency> <groupId>cn.ucloud.ufile</groupId> <artifactId>ufile-client-java</artifactId> <version>latest-release-version</version> </dependency> 
- 
Gradle dependencies { /* * your other dependencies */ implementation 'cn.ucloud.ufile:ufile-client-java:latest-release-version' } 
- 基本说明:
- 
所有API均包含同步执行(execute)和异步执行(executeAsync)两种执行方式。 
- 
同步执行会返回指定的业务结果类,若执行出错则会抛出UfileException为父类的异常; 
- 
异步执行需要传入UfileCallback的回调接口,执行成功时会回调onResponse,泛型为回调结果(即:同步执行的返回类型),值得注意的是,若Ufile Server业务错误,也会回调onResponse,请注意结果类中的信息,若出现异常,则回调onError。 
- 
如果是上传下载等耗时API,建议使用异步执行(executeAsync),并可以重写UfileCallback中的onProgress回调来进行进度监听

- 
必须在使用UfileClient之前调用,即:必须是UfileClient第一个调用的方法才有效。否则使用默认UfileClient.Config UfileClient.configure(new UfileClient.Config( new HttpClient.Config(int maxIdleConnections, long keepAliveDuration, TimeUnit keepAliveTimeUnit) .setTimeout(连接超时ms,读取超时ms,写入超时ms) .setExecutorService(线程池) .addInterceptor(okhttp3拦截器) .addNetInterceptor(okhttp3网络拦截器))); 
// Bucket相关API的授权器
BucketAuthorization BUCKET_AUTHORIZER = new UfileBucketLocalAuthorization(
            "Your PublicKey", "Your PrivateKey");
            
UfileClient.bucket(BUCKET_AUTHORIZER)
    .APIs       // Bucket相关操作API
    .execute() or executeAsync(UfileCallback<T>)- 
同步 try { BucketResponse res = UfileClient.bucket(BUCKET_AUTHORIZER) .createBucket(bucketName, region, bucketType) .execute(); } catch (UfileClientException e) { e.printStackTrace(); } catch (UfileServerException e) { e.printStackTrace(); } 
- 
异步 UfileClient.bucket(BUCKET_AUTHORIZER) .createBucket(bucketName, region, bucketType) .executeAsync(new UfileCallback<BucketResponse>() { @Override public void onResponse(BucketResponse response) { } @Override public void onError(Request request, ApiError error, UfileErrorBean response) { } }); 
关于ObjectConfig的region参数,是指您的bucket所创建在的地区编码,请参考UCloud 地区列表
