urlencoded [![Build Status](https://secure.travis-ci.org/iron/urlencoded.png?branch=master)](https://travis-ci.org/iron/urlencoded)
====

> URL Encoded middleware for the [Iron](https://github.com/iron/iron) web framework.
> Decode URL Encoded data from GET request queries and POST request bodies.

## Example

This example shows how to use urlencoded to parse GET request parameters.

```rust
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();
}
```

## Overview

urlencoded is a part of Iron's [core bundle](https://github.com/iron/core).

- Parses a URL query string into a `HashMap`s that maps `String` representations
of keys onto a `Vec` of `String` values.
- Values are stored in a `Vec` to ensure that no information is lost if a key appears multiple times.
The query string `a=b&a=c` will result in a mapping from `a` to `[b, c]`.
- Parses POST request bodies for web form data (MIME type: `application/x-www-form-urlencoded`).

## Installation

If you're using `Cargo` to manage dependencies, just add urlencoded to `Cargo.toml`:

```toml
[dependencies.urlencoded]
version = "*"
```

Otherwise, `cargo build`, and the rlib will be in your `target` directory.

## [Documentation](http://ironframework.io/doc/urlencoded)

Along with the [online documentation](http://ironframework.io/doc/urlencoded),
you can build a local copy with `cargo doc`.
