如何運行帶有彩色文本的終端的pexpect腳本

當我在交互式會話中運行時，Pexpect可以正常工作，但如果它具有彩色文本，那麼它不僅僅匹配文本，而是將文本與ansi顏色相匹配。這個正則表達式非常複雜和大。有人可以告訴我如何處理這件事。如何運行帶有彩色文本的終端的pexpect腳本

例如：

，而不是僅僅在尋找：

「opendaylight用戶@根」

其尋找：

「或「\ x1b [1mlogout \ x1b [0m'關閉 OpenDaylight。\ r \ r \ n \ r \ n \ x1b。\ r \ r \ n
\ r \ n \ x1b [36mopendaylight-user \ x1b [0m \ x1b [0m \ x1b [34mroot \ x1b [0m>]。

這只是表達的一部分。

import pexpect 
import os 
def ex1(): 
     os.chdir("opendaylight/distribution-karaf-0.3.4-Lithium-SR4/bin/") 
     child=pexpect.spawn("./karaf clean",cwd="/home/ubuntu/opendaylight/distribution-karaf-0.3.4-Lithium-SR4/bin/") 
     child.expect("[email protected]>") 
     print child.before 
ex1()

我改變了。如果它沒有足夠的PLZ，讓我知道你期望什麼樣的變化 – user7369931

嘗試搜索忽略[轉義碼]（https://en.wikipedia.org/wiki/ANSI_escape_code） –

我用expect_exact得到的答案（），而不是預期（）。 expect（）與正則表達式匹配，但expect_exact與字符串匹配。

import pexpect 
    import os 
    def ex1(): 
     os.chdir("opendaylight/distribution-karaf-0.3.4-Lithium-SR4/bin/") 
     child=pexpect.spawn("./karaf clean",cwd="/home/ubuntu/opendaylight/distribution-karaf-0.3.4-Lithium-SR4/bin/") 
     child.expect_exact("\x1b[36mopendaylight-user\x1b[0m\x1b[[email protected]\x1b[0m\x1b[34mroot\x1b[0m>") 
     print child.before 
    ex1()
