相关Issue

几个月前提过相关issue https://github.com/v2fly/v2ray-core/issues/1769 ，昨天测试v5.1.0版本，似乎还未修复。

你正在使用哪个版本的 V2Ray？

OS：Win10 21H2 V2Ray：v5.1.0

你的使用场景是什么？

比如使用 Chrome 通过 Socks/VMess 代理观看 YouTube 视频

你看到的异常现象是什么？

无法从stdin读取配置，未设置环境变量并移除了目录下config.json文件。 尝试使用v4.45.0内核是可以正常读取stdin。 以上测试均使用v4配置文件。

你期待看到的正常表现是怎样的？

正确读取stdin

请附上出错时软件输出的错误日志

未产生日志，仅输出如下信息。

V2Ray 5.1.0 (V2Fly, a community-driven edition of V2Ray.) Custom (go1.19 windows/amd64)
A unified platform for anti-censorship.

5.1 你这个是指两边版本的core运行参数有没有加run的区别？

[uuid855634]

v4.50 加与不加run 均能正常读取stdin。 v5.1.0 加run无法正常读取stdin， 不加run无法正常运行。

难道又是bug ？

I tested it on Arch Linux. I think you should close the standard input by youself. Input config then press Control and D.

在Win10 21H2上测试，使用v4配置格式在v4.50版本能正常读取StandardInput，v5.1.0使用-config参数从json文件中读取配置也很顺利，就是从StandardInput读取有点问题。有点迷。

貌似5.1 改了cli，文档没有更新，现在命令是这个 v2ray run -c **.json??

I think this is similar to #1949. This issue can be reproduced on v5.1.0 with a stdin stream larger than 2kB. Already fixed by #1923.

It seems to me that the issue has been fixed.
