URL Encoded middleware for the Iron web framework. Decode URL Encoded data from GET request queries and POST request bodies.
This example shows how to use urlencoded to parse GET request parameters.
extern crate iron;
extern crate urlencoded;
use iron::prelude::*;
use iron::status;
use urlencoded::UrlEncodedQuery;
fn log_params(req: &mut Request) -> IronResult<Response> {
// Extract the decoded data as hashmap, using the UrlEncodedQuery plugin.
match req.get_ref::<UrlEncodedQuery>() {
Ok(ref hashmap) => println!("Parsed GET request query string:\n {:?}", hashmap),
Err(ref e) => println!("{:?}", e)
};
Ok(Response::with((status::Ok, "Hello!")))
}
// Test out the server with `curl -i "http://localhost:3000/?name=franklin&name=trevor"`
fn main() {
Iron::new(log_params).http("127.0.0.1:3000").unwrap();
}
urlencoded is a part of Iron's core bundle.
- Parses a URL query string into a
HashMap
s that mapsString
representations of keys onto aVec
ofString
values. - Values are stored in a
Vec
to ensure that no information is lost if a key appears multiple times. The query stringa=b&a=c
will result in a mapping froma
to[b, c]
. - Parses POST request bodies for web form data (MIME type:
application/x-www-form-urlencoded
).
If you're using Cargo
to manage dependencies, just add urlencoded to Cargo.toml
:
[dependencies.urlencoded]
version = "*"
Otherwise, cargo build
, and the rlib will be in your target
directory.
Along with the online documentation,
you can build a local copy with cargo doc
.
