Question

我正在使用Jersey 2.16客户端来获取文件，当我尝试解析响应时，有些文件空了。

例如，在尝试获取URL时：

https://s1.yimg.com/uu/api/res/1.2/3LJG5Qp6cO9WVZ644ybK1A--/YXBwaWQ9eXRhY2h5b247aD0xNjQ7dz0yOTA7/https://ibdp.videovore.com/video/61260788?size=512x288

响应状态为200，我看到content-length标头指出应该有9081个字节，但是对inputStream.read的第一次调用返回-1。

以下是下载数据的代码：

private ByteArrayOutputStream downloadFile(Response response) {
    ByteArrayOutputStream outputStream = new ByteArrayOutputStream(1024);
    try {
        InputStream inputStream = response.readEntity(InputStream.class);
        byte[] bytes = new byte[1024];

        int readBytes = inputStream.read(bytes); // for the given URL this returns -1

        while (readBytes > 0) {
            outputStream.write(bytes, 0, readBytes);
            readBytes = inputStream.read(bytes);
        }
    } catch (Exception e) {
        e.printStackTrace();
    }
    return outputStream;
}

我得到的响应头：
