Question

发出以下Java REST GET请求后，我收到的回复看起来与文档页面上的资源表示不同：https://cloud.google.com/storage/docs/json_api/v1/objects#resource

有人能看出我做错了吗？

HttpGet httpGet = new HttpGet("https://www.googleapis.com/storage/" +
"v1/b/fir-sqlite-6d578.appspot.com/o/" +
"FwhnuuaipmSrOU2lhPw8JqRHddw2%2F-L7-dxfPvKAQhrTGCmFu%2F" +
"Catalina_Island.PNG");

我按如下方式处理响应。

// get the response entity
HttpEntity httpEntity = httpResponse.getEntity();

// read from an inputstream
InputStream inputStream = httpEntity.getContent();
final int MAX_BUF_LEN = 2048;
char[] aChar = new char[MAX_BUF_LEN];
Reader reader = new BufferedReader(new InputStreamReader(inputStream, "UTF-8"));
int n;
while ((n = reader.read(aChar)) != -1) {
    System.out.print(aChar);
}

我得到的回应如下。（我编辑了响应以删除大量冗余空白区域）
