您可以使用下面的代码作为您想要的内容的基础。您基本上需要进行一些定制的行拆分，以获得您想要的元素。请注意，用户代理是首先拆分报价字符的原因，因为这是唯一可能具有不可预测的空格数量的元素(AFAIK)。

我添加了一个简单的助手函数来显示元素的编号，并且展示了几种不同的拆分方法。变量名称可能需要更改，因为我不能100%确定您在nginx中登录的确切内容是什么……

def splitline(line: str) -> list:
    # these split is used multiple times, so do it once here
    # note that the useragent string might contain spaces, so we first need to split on quote chars
    split_quote = line.split('"')
    ip = split_quote[0].split()[0]
    date_time = split_quote[0].split('[')[1].split(']')[0]
    method = split_quote[1]
    http1, http2 = split_quote[2].split()
    useragent = split_quote[5]
    bytesize, resp_time1, prom, empty, ip_port, http3, resp_time2, http4, hex_string = split_quote[6].split()
    return [
        ip, date_time, method, http1, http2, useragent, bytesize, resp_time1, prom, empty, ip_port, http3, resp_time2, http4, hex_string
    ]

def print_elements(line):
    split_quote = line.split('"')
    for x, squote in enumerate(split_quote):
        print(f"{x:>2}    {squote}")
        for y, sspace in enumerate(squote.split()):
            print(f"{x:>2} {y:>2} {sspace}")

with open("logfile.log") as infile:
    data = infile.read().splitlines()

print_elements(data[0])

for line in data:
    print(splitline(line))
