pexpect python

index = child.expect(['Question 1:'])
os.system('sleep 2')
print 'Question 1:' + 'answer1'
child.sendline('answer1')

index = child.expect(['Question 2:'])
os.system('sleep 2')
print 'Question 1:' + 'answer2'
child.sendline('answer2')

index = child.expect(['Question 3:'])
os.system('sleep 2')
print 'Question 1:' + 'answer2'
child.sendline('answer2')

此时，我有一些代码可以检查问题2＆amp;问题3不符合。我检查了pexpect日志，发送的语句正是我想要的（字节数和字符串）。

但是，当我检查perl代码接受的内容时，它会得到以下内容：

问题1：'回答1'＆lt; - 正确

问题2：'回答1'＆lt; - INCORRECT

问题3：'回答2answer 2'＆lt; - 由于某种原因将其合并为一个

有什么想法吗？在产生我的pexpect对象时，我没有使用任何特殊的东西：child=pexpect.spawn(cmd,timeout=140)

编辑：添加了询问问题2＆amp;的perl代码函数。 3

sub getpw


sub getpw
{   my ($name, $var, $encoding) = @_;
    my $pw = $$var;

    PWD: while(1) {

        getvar($name, \$pw, 1);
        print "\n";
        system("/bin/stty echo");
        return if $pw eq $$var && length($pw) == 80;
        if (length($pw) > 32) {
            print STDERR "ERROR: Password cannot exceed 32 characters, please reenter.\n";
            next PWD;
        }

你的python方面的代码没有任何问题。检查代码的perl端。为了演示我在下面创建了一个python问题和答案相互调用的脚本。当您执行answers.py时，它将产生如下预期输出。此外，您不需要执行sleep语句，child.expect将阻塞，直到收到预期的输出。

<强> questions.py

answers = {}
for i in range(1, 4):
    answers[i] = raw_input('Question %s:' % i)
print 'resuls:'
print answers

<强> answers.py

import pexpect
child=pexpect.spawn('./questions.py', timeout=140)
for i in range(1, 4):
    index = child.expect('Question %s:' % i)
    child.sendline('answer%s' % i)

child.expect('resuls:')
print child.read()

<强>输出

{1: 'answer1', 2: 'answer2', 3: 'answer3'}

Python pexpect sendline内容被缓冲？

pexpect python

sub getpw

sub getvar
