IOS 视频播放报错"AVFoundationErrorDomain code:-11850/-11828"

问题现象

IOS 播放 video 报错，Andriod 播放正常

释义

11850:服务端不支持 byte 请求
11850:服务端支持 byte 请求，响应参数错误

问题原因

IOS 视频请求会先发送请求 header 带有 Range:bytes=0-1 的字节请求，期望结果为视频流中的一个字节，http 状态码返回 206，例如请求

curl -H "Range: bytes=0-1" http://127.0.0.1:8180/test.mp4

解决方案

JAVA配置
