subprocess.stdin

• <stream.Writable> | <null> | <undefined>

代表子进程的 stdin 的 Writable Stream。

¥A Writable Stream that represents the child process's stdin.

如果子进程等待读取其所有输入，则子进程将不会继续，直到通过 end() 关闭此流。

¥If a child process waits to read all of its input, the child process will not continue until this stream has been closed via end().

如果子进程是在 stdio[0] 设置为 'pipe' 以外的任何值的情况下生成的，那么这将是 null。

¥If the child process was spawned with stdio[0] set to anything other than 'pipe', then this will be null.

subprocess.stdin 是 subprocess.stdio[0] 的别名。这两个属性将引用相同的值。

¥subprocess.stdin is an alias for subprocess.stdio[0]. Both properties will refer to the same value.

如果无法成功生成子进程，则 subprocess.stdin 属性可以是 null 或 undefined。

¥The subprocess.stdin property can be null or undefined if the child process could not be successfully spawned.
