使用Google Storage Json Api(JAVA)进行批处理请求 [英] Batch request with Google Storage Json Api (JAVA)

问题描述

我正在尝试在来自appengine(JAVA)的一个批处理请求中设置多个ACL.我不确定发出请求的网址应该是什么. 文档注明"/batch".是否有可用的示例了? AFAIK无法通过API资源管理器进行测试.

I'm attempting to set multiple ACLs in one batch request from appengine (JAVA). I am not sure what the URL should be for making the request. The documentation states "/batch". Are there anymore examples available? AFAIK this is not possible to test from the API explorer.

推荐答案

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

Using the google-api-java-client library and the Storage JSON API, a batch request would look like this:

// 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("[e-mail]").setRole("READER"))
    .queue(batch, callback);
storage.objectAccessControls().insert("bucket-name", "object-key3",
    new ObjectAccessControl().setEntity("[e-mail]").setRole("OWNER"))
    .queue(batch, callback);

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

请注意，由于它的测试版有限，此刻您必须请求访问Storage JSON API.

Note that you'll have to request access to the Storage JSON API at the moment, as it's in limited beta.
