关于 rhai-url

此crate为Rhai脚本语言提供对url::Url的访问。

用法

Cargo.toml

[dependencies]
rhai-url = "0.0.4"

Rhai 脚本

// create a new Url
let url = Url("http://example.com/?q=query");

// get the absolute url as a string
print(url.href); // print 'http://example.com/?q=query'
print(url.to_string()); // print 'http://example.com/?q=query'

// get the url query string, without the leading ?
print(url.query); // print 'q=query'

// get the url fragment
print(url.fragment); // print ''

// hash is an alias of fragment
print(url.hash); // print ''

// clear the query
url.query_clear();
print(url.query); // print ''

// remove a query key
url.query_remove("q");

// query_remove with no arguments will clear the query string
url.query_remove();

// adds a query key value pair into the query string
url.query_append("q", "name");

您可以在测试中查看如何使用这些函数的示例。

Rust源代码

use rhai::{Engine, EvalAltResult};
use rhai::packages::Package;
use rhai_url::UrlPackage;
use url::Url;

fn main() -> Result<(), Box<EvalAltResult>> {
    // Create Rhai scripting engine
    let mut engine = Engine::new();

    // Create url package and add the package into the engine
    let package = UrlPackage::new();
    package.register_into_engine(&mut engine);

    // Print the url
    let url = engine.eval::<Url>(r#"Url("http://test.dev/")"#)?;

    println!("{}", url);

    // Print the url string, equivalent of to_string()
    let href = engine.eval::<String>(r#"Url("http://test.dev/").href"#)?;

    println!("{}", href);

    Ok(())
}
