PublicSuffix

Mozilla的Public Suffix List的本地Rust库

此库使用Mozilla的Public Suffix List以可靠地确定域名后缀。此crate提供了一个可动态更新的列表。如果您需要一个更快但静态的列表，请改用psl crate。

注意：此crate的v1版本包含验证域名和电子邮件地址的逻辑。从v2版本开始，此功能已移动到addr crate。此crate也不再为您下载列表。

设置

将此crate添加到您的Cargo.toml

[dependencies]
publicsuffix = "2"

示例

use publicsuffix::{Psl, List};

// the official list can be found at
// https://publicsuffix.org/list/public_suffix_list.dat
let list: List = "<-- your public suffix list here -->".parse()?;

let suffix = list.suffix(b"www.example.com")?;
assert_eq!(suffix, "com");
assert_eq!(suffix.typ(), Some(Type::Icann));

let domain = list.domain(b"www.example.com")?;
assert_eq!(domain, "example.com");
assert_eq!(domain.suffix(), "com");

let domain = list.domain("www.食狮.中国".as_bytes())?;
assert_eq!(domain, "食狮.中国");
assert_eq!(domain.suffix(), "中国");

let domain = list.domain(b"www.xn--85x722f.xn--55qx5d.cn")?;
assert_eq!(domain, "xn--85x722f.xn--55qx5d.cn");
assert_eq!(domain.suffix(), "xn--55qx5d.cn");

let domain = list.domain(b"a.b.example.uk.com")?;
assert_eq!(domain, "example.uk.com");
assert_eq!(domain.suffix(), "uk.com");

let domain = list.domain(b"_tcp.example.com.")?;
assert_eq!(domain, "example.com.");
assert_eq!(domain.suffix(), "com.");
