考慮 asset/logdata.txt 中的標(biāo)準(zhǔn) Web 日志文件。該文件記錄用戶在訪問網(wǎng)頁時(shí)進(jìn)行的訪問（就像這個(gè)?。Ｈ罩镜拿恳恍卸加幸韵马?xiàng)目：主機(jī)（例如，'146.204.224.152'）user_name（例如，'feest6811'注意：有時(shí)用戶名會(huì)丟失！在這種情況下，請(qǐng)使用“-”作為用戶名的值。）提出請(qǐng)求的時(shí)間（例如，'21/Jun/2019:15:45:24 -0700'）post 請(qǐng)求類型（例如，'POST /incentivize HTTP/1.1'注意：并非所有內(nèi)容都是 POST?。┠娜蝿?wù)是將其轉(zhuǎn)換為字典列表，其中每個(gè)字典如下所示：example_dict = {"host":"146.204.224.152",
"user_name":"feest6811",
"time":"21/Jun/2019:15:45:24 -0700",
"request":"POST /incentivize HTTP/1.1"}這是 txt 數(shù)據(jù)文件的示例。我寫了這幾行代碼：import redef logs(): with open("assets/logdata.txt", "r") as file: logdata = file.read() #print(logdata) pattern=""" (?P<host>.*) (-\s) (?P<user_name>\w*) (\s) ([POST]*) (?P<time>\w*) """ for item in re.finditer(pattern,logdata,re.VERBOSE): print(item.groupdict()) return(item)logs()它幫助我完成了任務(wù)"host"，"user_name"但是我無法繼續(xù)完成其余的要求。有人可以幫忙嗎？

請(qǐng)看下面的代碼：
import re
regex = re.compile(
r'(?P<host>(?:\d+\.){1,3}\d+)\s+-\s+'
r'(?P<user_name>[\w+\-]+)?\s+'
r'\[(?P<time>[-\w\s:/]+)\]\s+'
r'"(?P<request>\w+.+?)"'
)
def logs():
data = []
with open("assets/logdata.txt", "r") as f:
logdata = f.read()
for item in regex.finditer(logdata):
x = item.groupdict()
if x["user_name"] is None:
x["user_name"] = "-"
data.append(x)
return data
logs()

您正在使用\wget?user_names，但\w不包括-可以在日志中的內(nèi)容（通用日志格式（CLF）），因此您可以使用\S+（除空格之外的一個(gè)或多個(gè)任何內(nèi)容）作為替代方案。對(duì)于time您可以創(chuàng)建一個(gè)捕獲組，僅允許該字段的預(yù)期字符（類）（例如\w\s，-+時(shí)區(qū)、/日期和:時(shí)間）用方括號(hào)（文字）括起來，可以為request使用".
