具体的是\n
carriage return
（没有\t）

在curl的文档里有提到：
curl will make sure that each header you add/replace is sent with the proper end-of-line marker, you should thus not add that as a part of the header content: do not add newlines or carriage returns, they will only mess things up for you.

但是我想要到http协议的依据，这样是不行的
例如这里
http://www.w3.org/Protocols/rfc2616/rfc2616-sec2.html#sec2.2
有http的协议说header line是不能包括回车，必须要quote的么？

header

add

will

header的字段值可以包含换行符，但后面必需跟有空格或tab，否则后面的字符就会被当做下一个字段来解析。

@pyKun tab是\t

rfc2616 2.2 http://www.w3.org/Protocols/rfc2616/rfc2616.txt

"HTTP/1.1 header field values can be folded onto multiple lines if the
continuation line begins with a space or horizontal tab. All linear
white space, including folding, has the same semantics as SP. A
recipient MAY replace any linear white space with a single SP before
interpreting the field value or forwarding the message downstream."

@pyKun 我是指\r\n或\n后面加空格

@elden
貌似看懂点了，换行到下个文本间要加空格

那参照django和curl，其实我的client拒绝掉包含换行的value其实也没有问题

@pyKun django不清楚，但curl是遵循rfc2616规范的
