我已经对正确的主机名语法进行了一些阅读,并且无法弄清楚什么是非常合适的主机名/ URL语法您能告诉我以下URL在语法上是否正确吗?
I have done some reading on proper Hostname syntax and can't figure out what is a really proper Hostname/URL syntax Can you please tell me if the following URLs are syntactically correct?
1.2.3.4.5.6.7 / something 10.123.143.13333 / something 1.2 .3.4.5.6.7 / something some.host.name/something
这些只是我无法弄清楚的一些例子。 这些网址是否正确?
Those are just some examples that i couldn't figure out. Are those URLs correct?
推荐答案这些不是网址,因为它们缺少方案。
These are not URLs, as they are missing a scheme.
假设您的意思是HTTP网址,它们将是:
Assuming that you mean HTTP URLs, they would be:
1.2.3.4.5.6.7/something 10.123.143.13333/something 1.2.3.4.5.6.7/something some.host.name/somethingRFC 3986定义主机子组件(HTTP(S)URI的RFC 2616如下)。
RFC 3986 defines the syntax of the host subcomponent for all URIs (and RFC 2616 for HTTP(S) URIs follows that).
主机您的示例URI的名称将是:
The host names of your example URIs would be:
1.2.3.4.5.6.7 10.123.143.13333 1.2.3.4.5.6.7 some.host.name有效主机名遵循 IP-literal , IPv定义的语法(在上面链接的部分中) 4address ,或 reg-name :
Valid host names follow the syntax defined (in the section linked above) by IP-literal, IPv4address, or reg-name:
检查 IP-literal :
作为 IP-literal 要求用方括号括起来( [ ... ] ),没有 IP-文字主机名。
As an IP-literal requires enclosing square brackets ([…]), none are IP-literal host names.
检查 IPv4地址:
作为 IPv4地址必须包含三个。个字符, 1.2.3.4.5.6.7 , 1.2.3.4.5.6.7 ,以及部分。 host.name 不能是 IPv4address 主机名。
As an IPv4address must contain exactly three . characters, 1.2.3.4.5.6.7, 1.2.3.4.5.6.7, and some.host.name can’t be IPv4address host names.
虽然 10.123.143.13333 有三个。, 13333不是有效的 dec-octet ,所以它不是 IPv4地址。
While 10.123.143.13333 has three ., "13333" is not a valid dec-octet, so it’s not an IPv4address.
检查 reg-name :
您的所有示例均有效 reg-name 主机名,如 0-9 , az ,。是允许的字符。
All of your examples are valid reg-name host names, as 0-9, a-z, and . are allowed characters.
请注意,不意味着这些是DNS中的有效域名。 RFC 3986并未强制要求使用特定的注册名称查找技术。
Note that this does not mean that these are valid domain names in the DNS. RFC 3986 "does not mandate a particular registered name lookup technology".
