我正在尝试使用python子进程来调用第三方命令ParseAddress
。命令ParseAddress
打印出一行文本,要求用户输入地址列表,然后根据输入内容打印出堆栈跟踪信息。如果我手动运行该命令,则它看起来像:
$ParseAddress Appname <- Run the command in console
Paste the addresses - new line to continue
[0]0xaaaaaaaa <- a User paste a list of address here
[1]0xbbbbbbbb
[2]0xcccccccc
<- the user type 'enter' to continue
Stack Trace info: <-- results of running the ParseAddress
0xaaaaaaaa: Test::info::Runtest
0xbbbbbbbb: Test::info::SingleTestCase
0xcccccccc: ...
因此,如果我已经具有文本格式的列表地址,那么我认为subprocess()和communication()在这种情况下会有所帮助:
cmd = subprocess.Popen([ParseAddress, Appname], stdout=subprocess.PIPE, stdin=subprocess.PIPE, stderr=subprocess.STDOUT)
output, error = cmd.communicate(input="[0]0xaaaaaaaa\n[1]0xbbbbbbbb\n[2]0xcccccccc\n\n")
print(output)
当我将子进程与communite()一起使用时,控制台输出为:
$ParseAddress Appname
Paste the addresses - new line to continue
0xaaaaaaaa: ?? ??:0 <- subprocess.PIPE?
0xbbbbbbbb: ?? ??:0
0xcccccccc: ?? ??:0
Stack Trace info: <-- no results from the ParseAddress since the address info are in incorrect format
如果我使用
cmd.communicate(input="[0]0xaaaaaaaa\r\n[1]0xbbbbbbbb\r\n[2]0xcccccccc\r\n\r\n")
结果是:
$ParseAddress Appname
Paste the addresses - new line to continue
<-- No address here, no ideas why
Stack Trace info:
我的问题是为什么参数从[0]0xaaaaaaaa
更改为0xaaaaaaaa: ?? ??:0
?
使用communication()的正确方法是什么?
