java-servlet视频流ClientAbortException
作者：互联网
当我尝试从服务器流式传输视频文件时,我就遇到了servlet的问题.
服务器文件的代码
if (contentType == null) {
contentType = "application/octet-stream";
}
response.reset();
response.setBufferSize(ServerConfiguration.DEFAULT_BUFFER_SIZE);
response.setContentType(contentType);
response.setHeader("Content-Length", String.valueOf(file.length()));
response.setHeader("Content-Disposition", "inline; filename=\"" + file.getName() + "\"");
response.setHeader("Cache-Control", "public") ;
BufferedInputStream input = null;
BufferedOutputStream output = null;
try {
// Open streams.
input = new BufferedInputStream(new FileInputStream(file), ServerConfiguration.DEFAULT_BUFFER_SIZE);
output = new BufferedOutputStream(response.getOutputStream(), ServerConfiguration.DEFAULT_BUFFER_SIZE);
// Write file contents to response.
byte[] buffer = new byte[ServerConfiguration.DEFAULT_BUFFER_SIZE];
int length;
while ((length = input.read(buffer)) > 0) {
output.write(buffer, 0, length);
}
}
catch (Exception e) {
log(e);
}
finally {
// Gently close streams.
close(output);
close(input);
}
我已经将content-disposition设置为“ inline”,并且当我调试时,我可以看到请求在无限循环中到达服务器,并且每次它引发此错误时：

如果我将内容处置类型更改为附件-我能够下载文件并从localsytem播放文件(这意味着数据正确),但无法使用VLC播放器(网络)播放此视频文件(通过url)流选项)或我的自定义iphone媒体播放器.
我想做类似服务器-http://www.yo-yo.org/mp4/yu.mp4的操作.我可以通过提供VLC的URL或我的Iphone应用程序..网站的文件(http://www.yo-yo.org/mp4/)来播放此文件. .
yo-yo mp4文件的响应标头是
接受范围：字节
连接：保持活动
内容长度：7846115
内容类型：文本/纯文本；字符集= UTF-8
日期：2011年8月15日星期一18:01:12 GMT
ETag：“ 32a000f-77b8e3-3bd314df3c340”
保持活动：超时= 2
上次修改时间：2003年5月9日星期五,格林尼治标准时间
伺服器：Apache / 2.2.8(Fedora)
而我服务器的响应头是
缓存控制：公共
内容处置：内联； filename =“ 3648ef48-71bf-4393-9c0e-89fda68a683c.mp4”
内容长度：7846115
内容类型：视频/ mp4
日期：2011年8月15日星期一18:10:07 GMT
伺服器：Apache-Coyote / 1.1
请提供一些建议.我将非常感谢您的帮助
问候

解决方法:
我已经解决了上述问题. chrome发送字节范围的请求,服务器应处理此类请求,而不是在单个请求中写入完整的文件.
