管理文件访问权限（Android）

Get Object ACL 获取Object的ACL

以下代码用来获取对象的访问控制列表（ACL）：

client.getObjectACL("<bucketName>", "<objectKey>", new GetObjectACLResponseHandler() {

    @Override
    public void onSuccess(int statesCode, Header[] responceHeaders, AccessControlPolicy accessControlPolicy) {
	// 请求成功 返回accessControlPolicy对象
        Owner owner = accessControlPolicy.getOwner();
        HashSet<Grant> grants = accessControlPolicy.getAccessControlList().getGrants();
        for (Grant grant : grants) {
           // grant.getGrantee().getIdentifier()
           // grant.getPermission()
        }
    }

    @Override
    public void onFailure(int statesCode, Ks3Error error, Header[] responceHeaders, String response, Throwable paramThrowable) {
	//请求异常
    }
});

Put Object ACL 上传Object的ACL

以下代码用来写入对象的访问控制列表（ACL）：

PutObjectACLRequest request = new PutObjectACLRequest("<bucketName>", "<objectKey>");
// 使用封装好的权限对象
CannedAccessControlList cannedList = CannedAccessControlList.PublicRead;
// 当然也可以自行配置相关参数
// AccessControlList acList = new AccessControlList();
// request.setAccessControlList(acList);

request.setCannedAcl(cannedList);

client.putObjectACL(request, new PutObjectACLResponseHandler() {

    @Override
    public void onSuccess(int statesCode, Header[] responceHeaders) {
	//请求成功
    }

    @Override
    public void onFailure(int statesCode, Ks3Error error, Header[] responceHeaders, String response, Throwable paramThrowable) {
	//请求异常
    }
});
