Ruby Io.popen stucks和cmd未关闭
我使用这行代码从方法Ruby Io.popen stucks和cmd未关闭,ruby,Ruby,我使用这行代码从方法send\u crs调用方法send\u csr1: send_csr1(pipe.read,@username,@password) 问题是通常会执行下一行代码: pipe.close_write 但不知何故,它不会导致cmd从未关闭。当我手动关闭它时,会出现以下错误: in `read': Interrupt from stack.rb:49:in `block in send_csr' from stack.rb:45:in `popen'
send\u crs
调用方法send\u csr1
:
send_csr1(pipe.read,@username,@password)
问题是通常会执行下一行代码:
pipe.close_write
但不知何故,它不会导致cmd从未关闭。当我手动关闭它时,会出现以下错误:
in `read': Interrupt
from stack.rb:49:in `block in send_csr'
from stack.rb:45:in `popen'
from stack.rb:45:in `send_csr'
from stack.rb:88:in `block in <main>'
from stack.rb:87:in `each'
from stack.rb:87:in `<main>'
可能pipe.read正在阻塞,等待它读取“所有输入”,请尝试使用recv或其他方法,如get[?]没有mehod recv,但基本上这是一个好主意!
def send_csr
IO.popen('cmd', 'r+') do |pipe|
