Question

我试图传输本地mp3文件。我测试的歌曲长5：33s。在Chrome和edge中，歌曲在播放前不到4分钟播放。

这是我的服务

@Path ("clips")
public class ClipService {

    @GET
    @Path(...)
    @Produces("audio/mp3")
    public Response streamAudio() {

        Clip clip = ...
        StreamingOutput output = buildStreamingOutput(clip);
        return Response.ok(output).header(HttpHeaders.CONTENT_LENGTH,         clip.getLength()).build();
    }

    private StreamingOutput buildStreamingOutput(Clip clip)
        throws Exception {

        return new StreamingOutput() {
            @Override
            public void write(final OutputStream out)
                throws IOException, WebApplicationException {

                byte[] buffer = new byte[1024];
                int bytesRead;
                try (InputStream in = clip.getInputStream()) {
                    while ((bytesRead = in.read(buffer)) > 0) {
                        out.write(buffer, 0, bytesRead);
                    }
                    out.flush();
                }
            }
        };
    }
}

剪辑类

public class Clip {

    private InputStream inputStream; // The file
    private long length; // File.length()

错误我得到......

我已经尝试在我的AppConfig中将ServerProperties.OUTBOUND_CONTENT_LENGTH_BUFFER设置为0无效。

对于那些不希望被某些自命不凡的人阻挠的人来说，这是一个答案：）

通过取消原始请求并发送带有范围标题的第二个请求，结果显示我使用句柄content-type=audio/mp3测试的2个浏览器。

Here's another post详细说明了如何处理范围请求。

StreamingOutput - 流完成写入之前的EofException
