^(.*)HTTP(.*)$

        二、将-字符所在行-后面的内容全部删除。

例子：

39.100.84.190 - [-] [2023-09-09T00:16:52+08:00] "[-] [-] test" 400 [-] [- 150 1.576 -]

39.100.84.190 - [-] [2023-09-09T00:17:04+08:00] "[-] [-]  " 400 [-] [- 150 2.121 -]

39.100.84.190 - [-] [2023-09-09T00:17:12+08:00] "[-] [-] test" 400 [-] [- 150 3.801 -]

        三、将client: 字符所在行前面的内容全部删除。
