扩展包 pywebio_battery 的 run_shell 改进

[fengscarleteyes]

昨天用也是在windows7的环境下用 发现runshell 不支持gbk

__package__ = 'pywebio_battery'
__description__ = 'Utilities that help write PyWebIO apps quickly and easily.'
__url__ = 'https://pywebio.readthedocs.io/en/latest/battery.html'
__version__ = "0.3.0"
__version_info__ = (0, 3, 0, 0)

# 涉及代码块
def run_shell(cmd, output_func=partial(put_text, inline=True)):
    """Run command in shell and output the result to pywebio"""
    process = subprocess.Popen(cmd, shell=True, stdout=subprocess.PIPE, stderr=subprocess.STDOUT)
    while True:
        out = process.stdout.readline()
        if out:
            output_func(out.decode('utf8'))  # <- 这行 我手动改成了 output_func(out.decode('gbk'))

        if not out and process.poll() is not None:
            break

但是输出报错了 排查后 我手动进源码 改成 gbk 就能正常输出了...

与话题无关 如果平时遇到这类 涉及几个decode的问题量也不大 也不想太麻烦 有啥相对简洁优雅的方案呢? 直接try就可以吗? 我不是 开发科班出身 在这里额外请教下 ...
