params

A plugin for the Iron web framework that parses parameters from incoming requests from the following sources:

• JSON data (Content-Type: application/json)
• URL-encoded GET parameters
• URL-encoded Content-Type: application/x-www-form-urlencoded parameters
• Multipart form data (Content-Type: multipart/form-data)

This plugin combines all request parameters from these sources into a single params::Map accessible through any Iron request using req.get_ref::<params::Params>(). Example:

```rust fn handler(req: &mut Request) -> IronResult { use params::{Map, Params};

let map: Map = try!(req.get_ref::<Params>());

match map.find(&["user", "name"]) {
    // Assume, for example, the request URL here is:
    // http://localhost:3000/handler?user[name]=Marie
    Some(&Value::String(ref name)) => assert_eq!(name, "Marie"),
    _ => panic!("Unexpected parameter type!"),
}

} ```

You can perform custom request parameter deserialization by implementing params::FromValue for any Sized type. See src/conversion.rs for inspiration!

This crate is fully documented, and we're working on hosting it at ironframework.io.

See examples/params.rs for an interactive example.
