Google Storage Json Api(JAVA)的批量请求

Question

我正在尝试从appengine(JAVA)的一个批处理请求中设置多个ACL.我不确定提出请求的URL应该是什么.该文件指出,"/批".还有其他例子吗？AFAIK无法从API资源管理器进行测试.

Answer 1

使用google-api-java-client库和Storage JSON API,批处理请求如下所示:

// Create the Storage service object
Storage storage = new Storage(httpTransport, jsonFactory, credential);

// Create a new batch request
BatchRequest batch = storage.batch();

// Add some requests to the batch request
storage.objectAccessControls().insert("bucket-name", "object-key1",
    new ObjectAccessControl().setEntity("user-123423423").setRole("READER"))
    .queue(batch, callback);
storage.objectAccessControls().insert("bucket-name", "object-key2",
    new ObjectAccessControl().setEntity("user-guy@example.com").setRole("READER"))
    .queue(batch, callback);
storage.objectAccessControls().insert("bucket-name", "object-key3",
    new ObjectAccessControl().setEntity("group-foo@googlegroups.com").setRole("OWNER"))
    .queue(batch, callback);

// Execute the batch request. The individual callbacks will be called when requests finish.
batch.execute();

请注意,您目前必须请求访问Storage JSON API,因为它处于有限测试阶段.
