Python Fabric: How to answer to keyboard input?
提问by dzen
I would like to automate the response for some question prompted by some programs, like mysql prompting for a password, or apt asking for a 'yes' or ... when I want to rebuild my haystack index with a ./manage.py rebuild_index.
我想自动响应某些程序提示的某些问题，例如 mysql 提示输入密码，或 apt 要求输入“是”或 ... .
For MySQL, I can use the --password= switch, and I'm sure that apt has a 'quiet' like option. But how can I pass the response to other programs ?
对于 MySQL，我可以使用 --password= 开关，并且我确信 apt 有一个类似“安静”的选项。但是如何将响应传递给其他程序？

Why can't you just use pipes?
为什么你不能只使用管道？
For example, for an automated auto accept, just use yes, that just outputs a neverending stream of y.
例如，对于自动自动接受，只需使用yes，它只会输出一个永无止境的y.
yes | rm *.txt

If you are looking for a user to confirm an operation, use the confrim method.
如果您正在寻找用户来确认操作，请使用 confrim 方法。
if fabric.contrib.console.confirm("You tests failed do you want to continue?"):
#continue processing
Or if you are looking for a way to get input from the user, use the prompt method.
或者，如果您正在寻找一种从用户那里获取输入的方法，请使用提示方法。
password = fabric.operations.prompt("What is your password?")
回答by dzen
Those both methods are valid and works.
这两种方法都是有效的。
I choose the first one, because I didn't want to have any interaction with my deployment system.
我选择第一个，因为我不想与我的部署系统有任何交互。
So here is the solution I used:
所以这是我使用的解决方案：
% yes | ./manage.py rebuild_index
% yes | ./manage.py rebuild_index
