Question

我是python的新手，我正尝试（使用python）浏览大量大型自定义日志文件，以从某些GET请求中提取参数，并尝试从中获取som统计信息。我有点遥远，但我遇到了两个问题，我和我的同事无法弄清他们为什么让我们如此头痛。

我想做什么

使用字符串“ REQUEST = GetMap”提取所有行的服务名称。服务的名称在字符串“ / bios / wms / app /”和第一个问题标记“？”之间在行中。我提到它必须是第一个问号，因为每行中可以有多个问号（例如，我的日志示例中的倒数第二行有两个问号）。

我使用的正则表达式是：

rexp_name = r"(^.+/bios/wms/app/(?P<name>.+)\?)"

我的问题是我的正则表达式只是找到行中的最后一个问号，并返回“ / bios / wms / app /”和最后一个问号之间的整个字符串，而不仅仅是第一个问号。对于带有几个问号的行，该名称变得很长。

您是否有办法知道在第一个问号之后停止正则表达式？
