10.117.142.201>nelshost": -c: line 1: syntax error: unexpected end of file
command terminated with exit code 1
can someone help me?有人能帮我吗?
Plain split
doesn't keep quoted strings together.普通
split
不会将引用的字符串保持在一起。 shlex.split()
does; shlex.split()
确实; but why not just split it yourself?但为什么不自己拆分呢?
output = subprocess.run(
[ "kubectl", "exec", "-it", jmeter_pod,
"-n", namespace, "--",
"bash", "-c", "echo "+ ext_ip_lfe +">nelshost\" "],
text=True, check=True,
capture_output=True).stdout
Notice also the switch to subprocess.run
;还要注意切换到
subprocess.run
; you should avoid Popen
always when you can.你应该尽可能避免使用
Popen
。
