I have this URL as a String: "http://blah.com/a/b?a=1&b=2".
How can I remove or replace the GET parameter for b or strip the parameters entirely using Rust?
The ParseOptions of the rust-url package doesn't seem to give me anything for this.
Am I just limited to using String methods to find/replace?
let mut url = Url::parse("http://blah.com/a/b?a=1&b=2").unwrap();
url.set_query(None);
You can also take the query as pairs and manipulate it https://docs.rs/url/2.1.1/url/struct.Url.html#method.query_pairs_mut
Example how to update the query value for b (caution I'm a Rust beginner)
use url::Url;
fn main() {
let url = Url::parse("http://blah.com/a/b?a=1&b=2").unwrap();
let query: Vec<(_, _)> = url.query_pairs()
.filter(|p| p.0 != "b")
.collect();
let mut url2 = url.clone();
url2.set_query(None);
for pair in query {
url2.query_pairs_mut()
.append_pair(&pair.0.to_string()[..], &pair.1.to_string()[..]);
}
url2.query_pairs_mut()
.append_pair("b", "5");
println!("New Query: {}", url2);
}
