你需要用setvbuf或者flush,刷新下缓存

from bee.lua.

这里如果stdin是true,stdout就读不到数据,从echo.exe来看,也没有收到任何数据。
如果stdout是false,就可以正常读到数据。

但是如果stdin设置为true,写完数据后马上close,stdout是可以正常读到返回的数据的。

我想要双向交互,好像不行啊。

local subprocess = require("bee.subprocess")

local process, err = subprocess.spawn({
    "d:\\myprojects\\echo\\echo.exe",
    stdin = true,
    stdout = true,
})

-- process.stdin:write("hello server.\n")
-- process.stdin:close()
-- process:wait()

local all = process.stdout:read(50000)
print(all)
