subprocess.stdin
代表子进程的 stdin
的 Writable Stream
。
如果子进程等待读取其所有输入,则在通过 end()
关闭此流之前,子进程将不会继续。
如果子进程衍生时 stdio[0]
设置为 'pipe'
以外的任何值,则此将是 null
。
subprocess.stdin
是 subprocess.stdio[0]
的别名。
这两个属性将引用相同的值。
如果子进程无法成功衍生,则 subprocess.stdin
属性可以是 null
或 undefined
。
A Writable Stream
that represents the child process's stdin
.
If a child process waits to read all of its input, the child will not continue
until this stream has been closed via end()
.
If the child was spawned with stdio[0]
set to anything other than 'pipe'
,
then this will be null
.
subprocess.stdin
is an alias for subprocess.stdio[0]
. Both properties will
refer to the same value.
The subprocess.stdin
property can be null
or undefined
if the child process could not be successfully spawned.
