在python中从.dat文件中提取值

Question

输入file.dat文件：

2017-04-05 16:52:45.564|CN:-|SSLPROTOCOL:TLSv1.2|SSLCIPHER:ECDHE-RSA-AES256-GCM-SHA384|HTTPMETHOD:PATCH|URI:/portal/cache/num_active_capione_nodes|RESPONSETIME:9|STATUS:200|CLIENTIPADDRESS:10.202.30.123|CLIENT:portal-admin@capitalone.com|RESPONSEBODYSIZE:12

输出：我想要用^A分隔的值，例如：

TLSv1.2 ^A ECDHE-RSA-AES256-GCM-SHA384 ^A PATCH ^A /portal/cache/num_active_capione_nodes ^A 9 ^A 200 ^A 10.202.30.123 ^A portal-admin@capitalone.com ^A 12

Answer 1

这应该这样做：

with open("foo.dat", "r+") as f:
    data = f.read()
    data = ata.replace('|', ' ^A ')
    f.seek(0)
    f.write(data)
