Crate oauth1_request

Expand description

Yet yet yet another OAuth 1.0 client library.

Usage

Add this to your Cargo.toml:

[dependencies]
oauth = { version = "0.6", package = "oauth1-request" }

For brevity, we refer to the crate name as oauth throughout the documentation, since the API is designed in favor of qualified paths like oauth::get.

Create a request

A typical authorization flow looks like this:

// Define a type to represent your request.
#[derive(oauth::Request)]
struct CreateComment<'a> {
   article_id: u64,
   text: &'a str,
}

let uri = "https://example.com/api/v1/comments/create.json";

let request = CreateComment {
   article_id: 123456789,
   text: "A request signed with OAuth & Rust 🦀 🔏",
};

// Prepare your credentials.
let token =
   oauth::Token::from_parts("consumer_key", "consumer_secret", "token", "token_secret");

// Create the `Authorization` header.
let authorization_header = oauth::post(uri, &request, &token, oauth::HMAC_SHA1);
// `oauth_nonce` and `oauth_timestamp` vary on each execution.
assert_eq!(
   authorization_header,
   "OAuth \
        oauth_consumer_key=\"consumer_key\",\
        oauth_nonce=\"Dk-OGluFEQ4f\",\
        oauth_signature_method=\"HMAC-SHA1\",\
        oauth_timestamp=\"1234567890\",\
        oauth_token=\"token\",\
        oauth_signature=\"n%2FrUgos4CFFZbZK8Z8wFR7drU4c%3D\"",
);

// You can create an `x-www-form-urlencoded` string or a URI with query pairs from the request.

let form = oauth::to_form(&request);
assert_eq!(
   form,
   "article_id=123456789&text=A%20request%20signed%20with%20OAuth%20%26%20Rust%20%F0%9F%A6%80%20%F0%9F%94%8F",
);

let uri = oauth::to_query(uri.to_owned(), &request);
assert_eq!(
   uri,
   "https://example.com/api/v1/comments/create.json?article_id=123456789&text=A%20request%20signed%20with%20OAuth%20%26%20Rust%20%F0%9F%A6%80%20%F0%9F%94%8F",
);

See Request for more details on the derive macro.

If you want to authorize a request with dynamic keys, use oauth::ParameterList.

use std::fmt::Display;

let request = oauth::ParameterList::new([
   ("article_id", &123456789 as &dyn Display),
   ("text", &"A request signed with OAuth & Rust 🦀 🔏"),
]);

let form = oauth::to_form(&request);
assert_eq!(
   form,
   "article_id=123456789&text=A%20request%20signed%20with%20OAuth%20%26%20Rust%20%F0%9F%A6%80%20%F0%9F%94%8F",
);

Use oauth::Builder if you need to specify a callback URI or verifier:

let uri = "https://example.com/oauth/request_temp_credentials";
let callback = "https://client.example.net/oauth/callback";

let client = oauth::Credentials::new("consumer_key", "consumer_secret");

let authorization_header = oauth::Builder::<_, _>::new(client, oauth::HmacSha1::new())
   .callback(callback)
   .post(uri, &());
