返回的范围请求(HTTP range requests)视频流有很大几率会抛出异常

[ckvv]

Describe the problem（描述问题）

最小复现: https://github.com/ckvv/midway-range-request/blob/main/src/controller/home.controller.ts

启动后打开http://127.0.0.1:7001/ 有概率抛出以下异常信息，但是不影响视频播放

如果不用midwayjs实现的话就没有这个问题

这个更像是对方主动关闭了连接，试试直接 pipe 到 ctx.res 吧

[ckvv]

报错了

  return createReadStream(filePath).pipe(ctx.res);

}

[ckvv]

改成下面的不会再报错了，还是存在上面的Error: write EPIPE Error: read ECONNRESET 错误

ctx.respond = false;
return createReadStream(filePath).pipe(ctx.res);
