如何编写Python程序从IPMI响应提取十六进制值并转ASCII字符串

你可以通过逐行匹配关键词+字符串分割的方式提取目标内容，完整可运行代码如下：

# 模拟你从命令行拿到的完整输出，实际使用时可以替换为subprocess拿到的stdout内容
cmd_output = """$> set system cmd -i 33 -c raw 0x38 0x0b 0x06 -- command 

    Ipmi Response: 31 2e 30 38 2e 32 30 32 31 30 38 32 35 00 00 00 
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
   Completion Code: Success
"""

target_hex = None
# 逐行遍历匹配目标行
for line in cmd_output.splitlines():
    stripped_line = line.strip()
    # 不区分大小写匹配前缀，兼容性更强
    if stripped_line.lower().startswith("ipmi response:"):
        # 仅按第一个冒号分割，避免内容异常导致截取错误
        target_hex = stripped_line.split(":", 1)[1].strip()
        break

if target_hex:
    # 转ASCII同时去掉末尾的空字符
    ascii_result = ''.join(chr(int(i, 16)) for i in target_hex.split()).rstrip('\x00')
    print(f"转换结果：{ascii_result}")
else:
    print("未匹配到Ipmi Response对应内容")

如果你需要直接在Python中执行IPMI命令获取输出，可以用subprocess模块实现：

import subprocess

cmd = ["set", "system", "cmd", "-i", "33", "-c", "raw", "0x38", "0x0b", "0x06", "--", "command"]
run_result = subprocess.run(cmd, capture_output=True, text=True)
cmd_output = run_result.stdout

示例运行后输出结果为1.08.20210825，和你提供的十六进制串对应内容一致。
