如何从帖子标题中打印单个行，python

Question

这是重要的代码：

elif msgheader.startswith( 'POST' ):
        print "The POST msg:\n", msgheader

这是回应：

The POST msg:
POST / HTTP/1.1

Connection: keep-alive

comment=test

现在我的问题是如何打印出响应的各个行，例如评论字段。我尝试使用此代码，但出现错误：

print['comment']

Exception (with type 'exceptions.TypeError'): string indices must be integers, not str

假设您使用的是 urllib2，则必须使用类似的东西：

print msgheader.getheader('content-type')

你应该使用 requests 库：

print msgheader['content-type']
