HTTP头键允许的字符

Question

我检查了HTTP头键允许字符的不同文档。我没有发现任何具体的结果，比如这些字符是不允许的?有没有人能帮我找出哪些是HTTP头密钥中允许的有效字符?

Answer 1

header-field   = field-name ":" OWS field-value OWS
field-name     = token
token          = 1*tchar
tchar          = "!" / "#" / "$" / "%" / "&" / "'" / "*"
/ "+" / "-" / "." / "^" / "_" / "`" / "|" / "~"
/ DIGIT / ALPHA
; any VCHAR, except delimiters
